Emla Patch (lidocaine and prilocaine) is a topical anesthetic medication used to temporarily numb the skin before certain medical procedures. It helps reduce pain and discomfort caused by needles and other minor procedures involving the skin.

Emla Patch contains two active ingredients: lidocaine and prilocaine. These medications work together to block pain signals from the nerves in the area where the patch is applied.

Unlike medications that relieve pain throughout the body, Emla Patch works directly on the skin. It produces temporary local anesthesia without causing you to lose consciousness.

Your healthcare provider may recommend Emla Patch before medical procedures that involve puncturing or treating the skin.

Local Anesthesia Before Medical Procedures

Emla Patch is primarily used to provide local anesthesia to intact skin before procedures that may cause pain or discomfort.

It can be particularly helpful for people who are sensitive to needles or experience discomfort during routine medical treatments.

Emla Patch may be used for the following procedures:

  • Needle Insertions: Emla Patch helps numb the skin before procedures involving needles, such as blood tests, intravenous (IV) catheter insertion, and certain injections. By reducing pain at the application site, the patch can make needle-related procedures more comfortable.
  • Blood Tests: The patch may be applied before blood collection to reduce the pain associated with inserting a needle into the skin. This can be especially helpful for people who require frequent blood tests.
  • Intravenous (IV) Catheter Placement: Emla Patch may be used before inserting an IV catheter, which is a small tube placed into a vein to deliver fluids or medications. Numbing the skin beforehand may reduce discomfort during insertion.
  • Minor Dermatological Procedures: Emla Patch may help reduce pain during certain minor skin procedures. Depending on the procedure, your healthcare provider may recommend the patch before treatment.
  • Certain Skin Biopsies: For selected superficial skin procedures, Emla Patch may help numb the skin before treatment. However, deeper biopsies may still require additional local anesthetic injections to provide adequate pain relief.
  • Certain Laser Treatments: Your healthcare provider may recommend topical anesthesia before selected laser procedures to make treatment more comfortable. The suitability of Emla Patch depends on the treatment area, type of laser procedure, and instructions for your specific patch.

Emla Patch helps reduce pain where it is applied, but it may not completely eliminate all sensations during a procedure.

You may still feel pressure, movement, or some discomfort, particularly if the procedure affects deeper tissues beneath the skin.

Your healthcare provider will determine whether Emla Patch provides sufficient anesthesia or whether another form of pain management is necessary.

How Does Emla Patch Work?

Emla Patch contains lidocaine and prilocaine, two medications that belong to a class of drugs called local anesthetics.

Local anesthetics work by temporarily blocking the transmission of nerve signals in a specific area of the body.

Normally, when your skin is touched, punctured, or injured, sensory nerves send electrical signals to your brain. Your brain interprets some of these signals as pain.

Emla Patch helps interrupt this process by preventing nerves in the treated area from transmitting pain signals normally.

The patch delivers lidocaine and prilocaine through the surface of your skin, allowing the medications to reach nerve endings beneath the application site.

Lidocaine: Blocks Pain Signals

Lidocaine is a local anesthetic that helps prevent pain signals from travelling through sensory nerves.

It works by blocking sodium channels, which are structures in nerve cell membranes that allow electrical signals to travel along nerves.

When these sodium channels are blocked, nerve cells cannot transmit pain signals as effectively.

As a result, the treated skin gradually becomes numb, making needle insertion or other minor procedures less uncomfortable.

Prilocaine: Supports Local Anesthesia

Prilocaine is another local anesthetic that works similarly to lidocaine.

It also blocks sodium channels in nerve cells, preventing electrical signals from travelling normally.

When applied to the skin, prilocaine helps reduce nerve sensitivity and contributes to the numbing effect of the patch.

Combining prilocaine with lidocaine allows both medications to work together to provide temporary local anesthesia.

Combined Action of Lidocaine and Prilocaine

Emla Patch contains both lidocaine and prilocaine in a topical anesthetic formulation designed to deliver medication through intact skin.

Together, these ingredients help:

  • Temporarily Numb the Skin: Reduce sensitivity in the area where the patch is applied.
  • Block Pain Signals: Prevent sensory nerves from transmitting pain signals normally.
  • Reduce Needle-Related Discomfort: Make blood tests, injections, and IV catheter insertion more comfortable.
  • Support Minor Medical Procedures: Provide temporary surface anesthesia for certain procedures involving the skin.
  • Maintain Consciousness: Numb the treated area without causing general anesthesia or making you unconscious.

The numbing effect is temporary. Normal skin sensation gradually returns after the patch is removed and the medication wears off.

How Long Does Emla Patch Take to Work?

Emla Patch does not numb the skin immediately after application. The medication needs time to pass through the outer layer of your skin and reach the sensory nerves beneath the surface.

For most adults, Emla Patch should be applied at least one hour before a needle insertion or other procedure for which the patch is appropriate. The exact application time depends on your age and your healthcare provider’s instructions.

After the patch has been applied for the recommended period, the numbing effect may last for at least two hours after removal.

Even when the area is numb, you may still feel touch or pressure during the procedure. However, the patch helps reduce the pain associated with puncturing the skin. 

Important Information About Emla Patch

Emla Patch is designed for use on intact, unbroken skin. Do not apply it to open wounds, irritated skin, or infected areas unless your healthcare provider has specifically confirmed an appropriate treatment.

Avoid applying the patch near your eyes or mouth. Do not cut, reuse, or leave the patch on longer than recommended.

Tell your healthcare provider if you are allergic to lidocaine, prilocaine, or other local anesthetics. You should also discuss any history of methemoglobinemia, a condition that affects how your blood carries oxygen.

Special precautions are necessary when using Emla Patch in infants and young children because the recommended number of patches and application duration depend on age and other health factors.

Emla Patch helps make needle insertions and certain minor medical procedures more comfortable by temporarily numbing the skin. Always follow the instructions for your specific patch, since Emla Cream and Emla Patch have different approved uses.

For reference, Emla Patch is approved in Canada for topical pain relief on intact skin associated with needle insertion, including IV catheter placement and blood sampling. 

Emla Patch is a topical anesthetic medication used to temporarily numb the skin before certain medical procedures, such as blood tests, injections, and intravenous (IV) catheter insertion.

The patch contains two local anesthetics that work together to block pain signals from the nerves beneath the skin. This helps reduce discomfort when a needle enters the treated area.

Emla Patch is applied directly to clean, dry, unbroken skin at the site where the procedure will take place. It generally needs to remain on the skin for approximately one hour before the procedure to provide adequate numbing.

Each patch is designed to numb a circular area of skin approximately 1 inch (2.5 cm) in diameter. The exact numbing effect may vary depending on the application time, skin condition, and individual response.

Your healthcare provider will determine how many patches you need and how long they should remain in place. Do not apply more patches or leave them on longer than instructed.

How to Apply Emla Patch

Follow these steps to apply Emla Patch safely and correctly:

  1. Wash your hands: Clean your hands thoroughly with soap and water before handling the patch. This helps prevent dirt and bacteria from reaching the application site.
  2. Prepare the skin: Gently clean the area where the patch will be applied and make sure it is completely dry. Do not apply lotions, oils, or other skincare products to the application site unless your healthcare provider instructs you to do so.
  3. Open the package: Carefully remove Emla Patch from its protective packaging. Check that the patch is intact and has not been damaged.
  4. Remove the protective liner: Peel away the protective liner to expose the adhesive portion of the patch. Avoid touching the white, round area that contains the anesthetic medication.
  5. Position the patch: Place Emla Patch directly over the area where the needle will be inserted or the procedure will take place. Make sure the medicated center is positioned correctly.
  6. Secure the edges: Press firmly around the adhesive edges to attach the patch to your skin. Avoid pressing directly on the medicated center, as this may cause the medication to spread or leak.
  7. Record the application time: After securing the patch, gently press around the edges to confirm that it is attached properly. Use a ballpoint pen to write the application time on the patch’s outer surface, if directed. This helps you keep track of how long the patch has been in place.
  8. Leave the patch in place: Keep Emla Patch on your skin for the amount of time recommended by your healthcare provider, usually approximately one hour before the procedure.
  9. Remove the patch before the procedure: At the instructed time, carefully peel the patch away from your skin. Your healthcare provider may remove it immediately before starting the procedure.
  10. Dispose of the used patch: Fold the patch in half with the sticky sides together and discard it safely, away from children and pets. Wash your hands after removal unless your hands are the treatment site.

Do not reuse Emla Patch. Each patch is intended for a single application.

Important Tips When Using Emla Patch

Apply the Patch Before Your Procedure

Emla Patch requires time to numb the skin effectively.

For most adults, the patch is generally applied approximately one hour before a needle-related procedure, such as a blood test or IV catheter insertion.

During this time, lidocaine and prilocaine gradually penetrate the skin and reduce the sensitivity of nearby nerve endings.

Applying the patch immediately before a procedure may not provide enough time for the medication to work.

Follow the application schedule recommended by your healthcare provider, particularly if the patch is being used for a child or before a specific medical procedure.

Apply Only to Healthy, Unbroken Skin

Emla Patch is designed for use on intact skin.

Do not apply the patch to open wounds, cuts, scrapes, burns, rashes, or other areas of damaged skin.

Broken or inflamed skin may absorb more medication than healthy skin, which can increase the risk of side effects.

Avoid applying Emla Patch to mucous membranes, including the inside of your mouth or nose, unless a healthcare provider has specifically prescribed an appropriate formulation for that purpose.

If you are unsure whether the selected application site is suitable, ask your healthcare provider before using the patch.

Avoid Contact With Your Eyes, Nose, and Mouth

Emla Patch is intended for external use on the skin only.

Avoid getting the medication into your eyes, nose, ears, or mouth.

If the medication accidentally gets into your eye, rinse it gently with water or saline and seek medical advice promptly.

Because local anesthetics can temporarily reduce eye sensation, you may not immediately notice irritation or injury.

Avoid rubbing the affected eye and protect it from further irritation until normal sensation returns and a healthcare professional has assessed whether additional treatment is necessary.

If the medication accidentally enters your mouth, do not swallow it. Remove any remaining product and contact a healthcare professional for advice.

Do Not Leave the Patch on Longer Than Recommended

Always follow the application time recommended by your healthcare provider.

Leaving Emla Patch on your skin longer than instructed may increase the amount of lidocaine and prilocaine absorbed into your body.

Excessive absorption can increase the risk of side effects, including local skin reactions and, rarely, serious effects on the nervous system, heart, or blood.

The appropriate application time depends on your age, the number of patches used, and the procedure being performed.

Do not apply extra patches or extend the treatment period in an attempt to achieve deeper or longer-lasting anesthesia.

If your procedure is delayed, ask your healthcare provider whether the patch should remain in place or be removed.

Use Extra Caution When Applying Emla Patch to Children

Emla Patch may be used in certain pediatric patients when prescribed or recommended by a healthcare provider.

However, children, particularly infants and young children, may be more sensitive to local anesthetic medications.

The recommended number of patches and maximum application time depend on the child’s age and medical condition.

If you are applying Emla Patch to a child, make sure the patch is securely attached and cannot easily be removed.

Supervise your child to prevent them from peeling off the patch, chewing it, or putting it in their mouth.

Accidental swallowing or chewing of a medicated patch can be dangerous and requires immediate medical attention.

Do not use more patches than recommended or leave them on longer than instructed.

Protect the Numbed Skin From Injury

After Emla Patch has been removed, the treated skin may remain numb for some time.

Because the medication temporarily reduces pain sensation, you may not immediately notice minor injuries, irritation, or exposure to uncomfortable temperatures.

Until normal sensation returns, avoid scratching, rubbing, or bumping the treated area.

You should also avoid exposing the numb skin to excessive heat or cold, including heating pads, hot water bottles, ice packs, or very cold surfaces.

If you are applying Emla Patch to a child, supervise them to prevent scratching, biting, or rubbing the numb area.

Normal skin sensation will gradually return as the medication wears off.

How Long Does Emla Patch Take to Work?

Emla Patch generally begins providing noticeable skin numbness approximately one hour after application.

The medication needs time to penetrate the skin and reach the sensory nerves that transmit pain signals.

For most needle-related procedures, the patch should remain in place for at least one hour, unless your healthcare provider recommends a different application time.

The numbing effect may continue to increase briefly after the patch is removed. Following a one- to two-hour application, skin numbness generally lasts for at least two hours after removal.

However, the duration of anesthesia can vary depending on your age, the application site, and how long the patch remains on your skin.

You may still feel pressure or touch during your procedure, even when the treated area is numb. 

How to Remove and Dispose of Emla Patch

Emla Patch should be removed after the recommended application time, usually immediately before your medical procedure.

To remove the patch, gently lift one edge and slowly peel it away from your skin.

Avoid pulling aggressively, particularly if your skin is sensitive or irritated.

Once removed, fold the used patch in half with the adhesive sides together. This helps prevent accidental contact with any medication remaining on the patch.

Dispose of the patch according to the instructions provided with your medication or your pharmacist’s recommendations.

Keep used and unused patches away from children and pets. Even after use, a patch may contain enough medication to cause harm if it is chewed or swallowed.

Wash your hands thoroughly after handling and removing the patch, unless your hands are the treatment area.

Do not reuse an Emla Patch. Each patch is intended for a single application.

When to Contact Your Healthcare Provider

Contact your healthcare provider if you experience persistent redness, swelling, burning, itching, or irritation after using Emla Patch.

Mild temporary redness or paleness of the treated skin may occur and usually disappears as the medication wears off.

However, severe skin irritation, blistering, unusual swelling, or persistent discomfort should be assessed by a healthcare professional.

Seek immediate medical attention if you develop difficulty breathing, severe dizziness, unusual confusion, seizures, or blue, grey, or brownish discolouration of your skin, lips, or nails. These symptoms may indicate a serious reaction, including methemoglobinemia, a rare condition that reduces the blood’s ability to carry oxygen.

Always use Emla Patch exactly as directed. Applying the patch to clean, dry, intact skin, allowing sufficient time for numbness to develop, and following the recommended application duration can help reduce pain during needle-related procedures while minimizing the risk of side effects.

Emla Patch: Patch

  • 2.5/2.5%

Before using Emla Patch, tell your healthcare provider about any medical conditions, allergies, or medications you are taking.

Emla Patch is a topical anesthetic used to temporarily numb the skin before certain medical procedures, such as blood tests, vaccinations, injections, and intravenous (IV) catheter insertion.

Although Emla Patch is generally well tolerated when used correctly, it may cause side effects in some people. The risk of serious reactions may increase when too many patches are used, the patch is left on longer than recommended, or the medication is applied to damaged skin.

Certain medical conditions, including blood disorders, liver disease, and kidney disease, may also require additional precautions.

Always follow the recommended application instructions and treatment duration to help reduce the risk of unwanted side effects.

Allergic Reactions and Hypersensitivity

Do not use Emla Patch if you are allergic to lidocaine, prilocaine, other similar local anesthetics, or any of the ingredients in the patch.

Lidocaine and prilocaine belong to a class of medications called amide-type local anesthetics. These medications work by temporarily blocking nerve signals in the treated area, reducing pain and sensitivity.

Although allergic reactions to these medications are uncommon, they can occur in some people.

Tell your healthcare provider if you have a history of allergies, particularly if you have previously experienced an allergic reaction to a local anesthetic used during dental treatments, injections, or minor medical procedures.

Possible symptoms of an allergic reaction include:

  • Skin Rash: You may develop redness, hives, or an unusual rash.
  • Itching: The treated area or other parts of your body may become itchy.
  • Swelling: You may notice swelling around the application site, face, or lips.
  • Skin Irritation: Burning, redness, or discomfort may become more severe after applying the patch.
  • Breathing Difficulties: A severe allergic reaction may cause wheezing, shortness of breath, or throat swelling.

Stop using Emla Patch and contact your healthcare provider if you develop a new rash, unusual swelling, or persistent irritation.

Seek emergency medical attention immediately if you experience difficulty breathing or swelling of your face, tongue, lips, or throat.

Application to Damaged or Irritated Skin

Emla Patch is designed for use on healthy, intact skin.

Do not apply the patch to open wounds, cuts, scrapes, burns, rashes, or other areas where the skin is damaged.

Broken or inflamed skin may absorb lidocaine and prilocaine more quickly than healthy skin. This can increase the amount of medication entering your bloodstream and raise your risk of side effects.

Tell your healthcare provider if you have eczema, atopic dermatitis, psoriasis, or another skin condition affecting the area where you plan to apply the patch.

Some inflammatory skin conditions may change how quickly the medication is absorbed, which can affect the appropriate application time.

Emla Patch should not be applied to mucous membranes, including the inside of your mouth or nose.

If the skin at your intended application site is irritated, infected, or damaged, ask your healthcare provider whether another location or anesthetic treatment would be more appropriate.

Use in Infants and Children

Emla Patch should be used with particular caution in infants and young children because they may be more sensitive to the effects of lidocaine and prilocaine.

One of the most important concerns is methemoglobinemia, a rare but potentially serious blood condition that reduces the blood’s ability to carry oxygen effectively.

Infants younger than three months are at greater risk because their bodies are less able to process certain substances that can cause methemoglobinemia.

According to Canadian product information, Emla Patch should not be used in infants younger than three months unless a healthcare professional specifically recommends it. When prescribed for this age group, strict limits apply to the number of patches and application duration. 

For older infants and children, the recommended number of patches and maximum application time depend on age, body weight, and medical condition.

Children should be monitored carefully during and after treatment, especially if they have other risk factors for methemoglobinemia.

Possible warning signs include unusual tiredness, weakness, difficulty breathing, or blue, grey, or brownish discolouration of the lips, skin, or fingernails.

If your child develops any of these symptoms, remove the patch and seek emergency medical attention.

Never apply more patches or leave them on longer than recommended by your child’s healthcare provider.

Methemoglobinemia Risk

Emla Patch contains prilocaine, a local anesthetic that can occasionally cause methemoglobinemia.

Methemoglobinemia occurs when an excessive amount of hemoglobin in the blood changes into a form that cannot carry oxygen effectively.

As a result, your body’s tissues and organs may not receive enough oxygen.

Although this condition is rare, it can become life-threatening if not treated promptly.

The risk may be higher in infants, people with glucose-6-phosphate dehydrogenase (G6PD) deficiency, individuals with certain blood disorders, and those taking medications that increase methemoglobin formation.

Possible symptoms include:

  • Blue or Grey Skin Discoloration: Your lips, fingernails, or skin may appear bluish, greyish, or brownish.
  • Difficulty Breathing: You may experience shortness of breath or unusually rapid breathing.
  • Severe Tiredness: You may feel extremely weak or exhausted.
  • Dizziness or Headache: You may become lightheaded or experience a persistent headache.
  • Confusion: Severe cases may cause unusual confusion or reduced alertness.
  • Rapid Heartbeat: Your heart may beat faster as your body attempts to compensate for reduced oxygen delivery.

Symptoms may develop during or after use.

Remove Emla Patch and seek emergency medical attention immediately if you notice signs of methemoglobinemia.

Tell your healthcare provider if you or your child have G6PD deficiency, a history of methemoglobinemia, or another condition affecting how the blood carries oxygen.

Drug Interactions and Concurrent Medications

Before using Emla Patch, tell your healthcare provider or pharmacist about all medications and supplements you take.

Certain medications may increase the risk of methemoglobinemia when used with prilocaine.

These include some antibiotics and other medications that can affect the blood’s ability to carry oxygen.

Examples include sulfonamide antibiotics, dapsone, and certain other medications associated with methemoglobin formation.

Using Emla Patch with other local anesthetics may also increase your overall exposure to lidocaine or similar medications.

This could increase the risk of side effects affecting your nervous system or heart.

Certain medications used to treat irregular heart rhythms, such as amiodarone or mexiletine, may also require additional precautions.

Tell your healthcare provider if you use prescription medications, over-the-counter products, topical anesthetic creams, herbal supplements, or other products containing lidocaine or prilocaine.

Do not combine Emla Patch with other numbing medications unless your healthcare provider confirms that they can be used safely together.

Systemic Absorption and Overuse

Although Emla Patch is applied directly to your skin, small amounts of lidocaine and prilocaine can enter your bloodstream.

When the patch is used correctly, the amount absorbed is generally limited. However, using too many patches, leaving them on longer than recommended, or applying them to damaged skin may increase absorption.

Excessive exposure to local anesthetics can cause serious side effects involving the nervous system, heart, or blood.

Possible warning signs include dizziness, unusual drowsiness, ringing in the ears, confusion, tremors, or seizures.

In severe cases, excessive local anesthetic absorption may cause dangerous changes in heart rhythm or other life-threatening complications.

The risk may be greater in people with severe liver disease, kidney disease, certain heart conditions, or other medical conditions that affect how the body processes medications.

Your healthcare provider may recommend a different number of patches or a shorter application time based on your medical history.

Do not use more patches or leave Emla Patch on your skin longer than instructed. Applying additional medication will not necessarily improve pain relief and may increase the risk of serious complications.

Choking and Accidental Swallowing

Emla Patch can present a choking or poisoning hazard if it becomes detached and is placed in a child’s mouth.

Infants and young children may try to remove the patch, chew it, or swallow it.

Because the patch contains lidocaine and prilocaine, accidental swallowing can expose a child to potentially harmful amounts of local anesthetic.

If you are applying Emla Patch to a child, make sure the patch is securely attached and cannot easily be removed.

Supervise your child during treatment, particularly if they frequently put their fingers or objects into their mouth.

Take extra care with infants who are lying on their stomachs or in positions where the patch may become loose or difficult to monitor.

Avoid placing the patch where a child can easily reach it or pull it off.

After use, fold the patch in half with the adhesive sides together and dispose of it safely.

If a child chews or swallows an Emla Patch, seek immediate medical advice or contact a poison control center. Do not wait for symptoms to develop.

Eye Contact and Eye Irritation

Emla Patch should not come into contact with your eyes.

Lidocaine and prilocaine temporarily reduce sensation in the areas where they are applied. If the medication enters your eye, it may cause irritation and temporarily reduce your eye’s ability to detect discomfort.

This can increase the risk of corneal injury because you may not immediately notice irritation, scratching, or foreign particles.

If Emla medication accidentally gets into your eye, rinse it thoroughly with clean water or saline.

Avoid rubbing your eye and protect it from further irritation until normal sensation returns.

Contact your healthcare provider promptly if you experience persistent redness, pain, blurred vision, or sensitivity to light.

Do not apply Emla Patch around your eyes unless a healthcare professional has specifically instructed you to use an appropriate anesthetic preparation for that area.

Skin Irritation and Local Reactions

Some people may experience mild skin reactions after applying Emla Patch.

These reactions usually occur at the application site and may include redness, temporary whitening of the skin, mild swelling, itching, or a burning sensation.

The skin may also feel unusually warm or sensitive after the patch is removed.

In most cases, these effects are temporary and disappear as the medication wears off.

However, persistent redness, severe itching, blistering, or increasing swelling may indicate irritation or an allergic reaction.

If you experience severe or worsening skin symptoms, remove the patch and contact your healthcare provider.

Avoid scratching or rubbing the treated area, especially while your skin remains numb.

Because Emla Patch temporarily reduces pain sensation, you may not notice minor injuries or irritation immediately.

Protect the treated skin from excessive heat, cold, scratching, and pressure until normal sensation returns.

Pregnancy and Breastfeeding

If you are pregnant, planning to become pregnant, or breastfeeding, speak with your healthcare provider before using Emla Patch.

Lidocaine and prilocaine may enter your bloodstream after being absorbed through the skin. The amount absorbed depends on the number of patches used, how long they remain in place, and the condition of your skin.

Available information has not established a clear risk of birth defects from appropriate use, but data specifically evaluating Emla Patch during pregnancy are limited.

Your healthcare provider will consider whether the expected benefits of temporary skin anesthesia outweigh any potential risks.

If you are breastfeeding, small amounts of lidocaine and prilocaine may pass into breast milk after systemic absorption. However, exposure to a breastfed infant is expected to be low when the patch is used appropriately.

Your healthcare provider can determine whether Emla Patch is suitable for you while breastfeeding.

Avoid applying the patch directly to your breasts or nipples unless specifically instructed by a healthcare professional.

Do not use additional patches or extend the recommended application time without medical advice.

When to Contact Your Healthcare Provider

Contact your healthcare provider if you develop persistent skin redness, swelling, burning, itching, or other unexpected symptoms after using Emla Patch.

You should also seek medical advice if you have an existing skin condition, a history of allergic reactions to local anesthetics, or concerns about using the patch on a child.

Seek emergency medical attention immediately if you experience difficulty breathing, seizures, severe confusion, an irregular heartbeat, or blue, grey, or brownish skin discolouration. These symptoms may indicate a serious reaction requiring urgent treatment.

Always follow the recommended number of patches, application time, and instructions for the treatment area.

Emla Patch can help reduce pain during minor medical procedures, but correct application is essential for safe and effective use. Following the recommended precautions can help minimize skin irritation, excessive anesthetic absorption, and other potentially serious side effects.

How Long Should I Leave the Emla Patch On?

Emla Patch is generally applied at least one hour before a needle-related procedure, such as a blood test, vaccination, or intravenous (IV) catheter insertion. The patch needs time to allow the local anesthetic ingredients to penetrate your skin and temporarily block pain signals from the nerves beneath the surface. Applying it approximately one hour before your procedure helps provide sufficient numbing to reduce discomfort. For adults, the patch may remain in place for longer when appropriate, but it should not be left on for more than five hours. The maximum application time is shorter for infants and may vary for children depending on their age. Leaving Emla Patch on longer than recommended does not necessarily improve pain relief and may increase the amount of medication absorbed into your bloodstream. Your healthcare provider will determine the appropriate application time based on your age, medical history, and the procedure being performed. Always follow the recommended application time. If your medical procedure is delayed, ask your healthcare provider whether you should remove the patch or leave it in place.

Can I Reuse the Emla Patch?

No, Emla Patch is designed for single use only and should never be reused. Each patch contains a specific amount of lidocaine and prilocaine that gradually penetrates the skin during application. Once the patch has been used, the amount of medication remaining may not provide reliable pain relief. Reusing a patch may also increase the risk of skin irritation or contamination, especially if it has come into contact with your hands or other surfaces. After removing Emla Patch, carefully fold it in half with the adhesive sides together. This helps prevent accidental contact with any medication remaining on the patch. Dispose of the used patch according to the instructions on the packaging or your pharmacist’s recommendations. Keep used and unused patches out of the reach of children and pets. Even after use, a patch may contain enough medication to cause harm if accidentally chewed or swallowed. If you need local anesthesia for another procedure, use a new patch and follow the recommended application instructions.

Can Emla Be Used to Numb Other Areas of the Body Besides the Skin?

Emla Patch is specifically designed to provide temporary local anesthesia on intact, unbroken skin. It is commonly used to reduce pain before needle insertions, blood tests, vaccinations, and certain other minor medical procedures. The patch should not be applied to open wounds, cuts, burns, rashes, or mucous membranes, such as the inside of your mouth or nose. Applying Emla Patch to damaged or sensitive tissues may increase the absorption of lidocaine and prilocaine, potentially raising the risk of side effects. Although Emla Cream may be used for additional medical purposes, including certain procedures involving mucous membranes or leg ulcers, these uses require specific instructions and precautions. Emla Patch and Emla Cream are different formulations and should not be used interchangeably without guidance from a healthcare professional. If you need to numb an area other than intact skin, ask your healthcare provider which local anesthetic formulation is most appropriate.

Is Emla Patch Safe for Use in Infants?

Emla Patch may be used in infants, including full-term newborns, when appropriate. However, special precautions are necessary because infants are more sensitive to local anesthetic medications. One of the main concerns is methemoglobinemia, a rare but potentially serious condition that reduces the blood’s ability to carry oxygen effectively. Infants younger than three months have a greater risk of developing methemoglobinemia because their bodies are still developing the ability to process certain substances. For infants younger than three months, Emla Patch should only be used under medical guidance. The recommended limit is one patch applied for no longer than one hour. For infants aged three to twelve months who meet the appropriate weight requirements, up to two patches may be permitted, depending on the healthcare provider’s instructions. The maximum application duration is generally four hours. Children older than twelve months have different dosing limits based on their age and body weight. Parents and caregivers should carefully follow the recommended number of patches and application time. Children should also be supervised to prevent them from removing, chewing, or swallowing the patch. Contact your healthcare provider before using Emla Patch on an infant, particularly if the child was born prematurely, has a blood disorder, or takes medications that may increase the risk of methemoglobinemia. Seek emergency medical attention if your child develops difficulty breathing, unusual weakness, or blue, grey, or brownish discoloration around the lips, skin, or fingernails. 

Can I Apply More Than One Emla Patch at a Time for a Larger Area of Numbing?

Yes, more than one Emla Patch may be used when appropriate, but the number of patches depends on your age, the size of the treatment area, and the procedure being performed. Each Emla Patch is designed to numb a small, circular area of skin approximately one inch (2.5 cm) in diameter. For procedures involving more than one needle insertion site, your healthcare provider may recommend applying separate patches to the selected areas. Adults may use multiple patches when necessary, provided they follow the recommended application limits. For infants and children, stricter limits apply to the number of patches that can be used at the same time and how long they may remain on the skin. Applying too many patches can increase the amount of lidocaine and prilocaine absorbed into your bloodstream, raising the risk of serious side effects. If you need to numb a larger area of skin, your healthcare provider may recommend Emla Cream or another suitable anesthetic treatment. Do not apply additional Emla Patches or cover larger areas than recommended without consulting your healthcare provider. 

Can I Purchase Emla Without a Prescription?

Yes, Emla Patch is available without a prescription in Canada and can be purchased at participating pharmacies. It contains lidocaine and prilocaine, two local anesthetics that temporarily numb the skin and help reduce discomfort during needle-related procedures. Emla is available in different formulations, including patches and cream. Your pharmacist can help you choose the most appropriate option based on the procedure and the area that needs numbing. Although Emla Patch is available without a prescription in Canada, you should still follow the product instructions carefully. Speak with your pharmacist or healthcare provider before using Emla Patch if you have a history of allergic reactions to local anesthetics, certain blood disorders, or other medical conditions that may increase your risk of side effects. If you are purchasing Emla Patch for an infant or young child, ask a healthcare professional about the recommended number of patches and maximum application time. Prescription requirements and availability may differ in other countries. 

Can I Apply the Emla Patch Myself, or Do I Need Someone to Help Me?

You can usually apply Emla Patch yourself, provided you can comfortably reach the treatment area and follow the application instructions correctly. The patch is designed for convenient use at home or in a healthcare setting before certain medical procedures. Before applying the patch, wash your hands and make sure the selected skin area is clean, dry, and free from cuts, rashes, or irritation. Carefully remove the protective liner without touching the white, round medicated area. Place the patch over the site where the procedure will take place and press firmly around the adhesive edges to keep it securely attached. The patch is generally applied approximately one hour before your procedure. Recording the application time can help you remember when it should be removed. If you have difficulty reaching the application site, limited hand movement, or another condition that makes applying the patch challenging, a caregiver or healthcare professional can help you. For children, an adult should apply the patch and supervise them while it remains in place to prevent accidental removal or swallowing. Before applying Emla Patch, confirm the correct application site with your healthcare provider, particularly if you are preparing for a vaccination, blood test, or IV catheter insertion. Using Emla Patch correctly can help reduce pain and discomfort during minor medical procedures. Whether you apply it yourself or receive assistance, always follow the recommended application time, number of patches, and safety precautions.
