Prinivil contains the active ingredient lisinopril, a prescription medication used to treat high blood pressure, heart failure, and certain patients after a heart attack.
It belongs to a group of medicines called angiotensin-converting enzyme (ACE) inhibitors. These medicines help relax blood vessels and reduce the amount of work the heart has to do.
Prinivil is commonly prescribed to treat hypertension, or high blood pressure, in adults and in children 6 years of age and older.
High blood pressure means that blood is pushing against the walls of the arteries with more force than normal. Over time, this can place extra strain on the heart and damage blood vessels.
Because high blood pressure often causes no obvious symptoms, many people may feel well even when their blood pressure is too high.
Prinivil helps blood vessels relax and widen, making it easier for blood to move through the body.
When blood can flow more easily, the pressure inside the blood vessels decreases. This helps reduce the workload on the heart and can improve overall circulation.
Keeping blood pressure within a healthy range can help lower the risk of serious complications over time.
These may include stroke, heart attack, heart failure, kidney damage, and other blood vessel problems.
Prinivil is often used as part of a long-term treatment plan that may also include diet, exercise, and other medications.
Prinivil may also be prescribed to treat heart failure.
Heart failure does not mean that the heart has completely stopped working. It means that the heart is not pumping blood as effectively as the body needs.
This can lead to symptoms such as shortness of breath, tiredness, swelling in the legs or ankles, and difficulty with physical activity.
By relaxing blood vessels, Prinivil makes it easier for the heart to pump blood forward.
This reduces the resistance the heart has to work against and may help improve circulation throughout the body.
Over time, this can help reduce strain on the heart and improve symptoms in some people with heart failure.
Prinivil may also be prescribed after an acute heart attack in certain patients.
A heart attack can damage part of the heart muscle and may reduce the heart’s ability to pump efficiently.
Lisinopril may be used as part of a broader treatment plan to help support heart function and improve survival after a heart attack.
The left ventricle is the main pumping chamber of the heart.
After a heart attack, this chamber may become weaker and less effective at pumping blood. This is known as left ventricular dysfunction.
Prinivil can help reduce the workload on the left ventricle and improve the way blood moves through the circulation.
Prinivil blocks an enzyme in the body called angiotensin-converting enzyme, or ACE.
Normally, ACE helps produce a hormone called angiotensin II.
Angiotensin II causes blood vessels to tighten and also encourages the body to retain sodium and water. Both of these effects can increase blood pressure and make the heart work harder.
By blocking ACE, lisinopril reduces the production of angiotensin II.
As a result, blood vessels remain more relaxed and open.
This lowers blood pressure and decreases the resistance against which the heart must pump.
ACE inhibition can also reduce signals that encourage the body to retain salt and water.
This may help reduce the amount of fluid the heart has to circulate, which can be especially helpful in people with heart failure.
Reducing blood pressure and the workload on the heart can help protect the heart from ongoing strain.
In people with heart failure or after a heart attack, ACE inhibitors such as lisinopril may also help limit harmful changes in the size and shape of the heart that can occur after heart damage.
Prinivil begins lowering blood pressure relatively soon after a dose, but the full effect may take several weeks of regular treatment.
If you are taking it for heart failure, improvements in symptoms may also develop gradually.
Continue taking it exactly as prescribed even if you do not notice an immediate difference.
Prinivil does not cure high blood pressure or heart failure.
Instead, it helps control the condition and reduce the risk of complications when used regularly.
Because high blood pressure may not cause symptoms, feeling well does not necessarily mean that the medication is no longer needed.
Take Prinivil consistently and at about the same time each day unless your healthcare provider gives you different instructions.
Do not stop taking it suddenly or change your dose on your own.
Your healthcare provider may monitor your blood pressure, kidney function, and potassium levels during treatment to make sure the medication is working safely and effectively.
Lisinopril is taken by mouth, usually once a day, exactly as prescribed by your healthcare provider.
You can take it with or without food. Food does not significantly affect how lisinopril works, so you can choose a time that fits your routine.
Try to take your dose at about the same time every day. This can help you remember your medication and keep a steady amount of lisinopril in your body.
The dose of lisinopril varies depending on the condition being treated.
For adults, doses may range from 2.5 mg to 40 mg once daily.
Your healthcare provider will choose the dose based on factors such as your blood pressure, heart condition, kidney function, other medications, and how well you tolerate treatment.
Some people may need to begin with a lower dose.
This may include people who have kidney problems, are taking diuretics or other blood pressure medicines, are dehydrated, or are more likely to experience a sudden drop in blood pressure.
Starting with a lower dose allows your healthcare provider to see how your body responds before increasing the medication.
When lisinopril is used for high blood pressure, treatment is usually started at a dose appropriate for your individual needs.
Your healthcare provider may gradually increase the dose if your blood pressure remains too high.
Blood pressure should be checked regularly so your provider can determine whether your current dose is working well.
For heart failure, lisinopril is often started at a low dose, such as 2.5 mg to 5 mg once daily.
The dose may then be gradually increased depending on your symptoms, blood pressure, kidney function, and potassium levels.
Starting slowly can help reduce the risk of dizziness or a sudden drop in blood pressure.
Lisinopril may also be prescribed after a heart attack in certain patients.
The dosing schedule may be different from the schedule used for high blood pressure or heart failure.
If lisinopril is prescribed after a heart attack, follow the exact dosing instructions provided by your healthcare team.
Lisinopril may be prescribed for children 6 years of age and older with high blood pressure.
The dose is generally based on the child’s body weight.
A healthcare provider will calculate the appropriate starting dose and may gradually adjust it depending on the child’s blood pressure response.
Children should only take lisinopril under the supervision of a healthcare professional.
Take the tablet with a glass of water.
Swallow it as directed. If you have difficulty swallowing tablets, ask your pharmacist or healthcare provider whether another formulation or method of administration is appropriate.
Lisinopril begins lowering blood pressure after you start taking it, but you may not notice any physical difference.
The full blood-pressure-lowering effect may take approximately 2 to 4 weeks of regular treatment.
Continue taking it every day even if you do not feel different.
If you are taking lisinopril for heart failure, improvements may occur more gradually.
It may take several weeks or longer before you notice changes in symptoms such as shortness of breath, tiredness, or your ability to perform daily activities.
Do not stop treatment simply because you do not notice an immediate improvement.
Lisinopril works best when taken regularly every day.
High blood pressure often does not cause obvious symptoms, so feeling well does not mean that your blood pressure is controlled without medication.
Continue treatment for as long as your healthcare provider recommends.
If you forget to take lisinopril, take the missed dose when you remember unless it is almost time for your next dose.
If your next scheduled dose is close, skip the missed dose and continue with your usual schedule.
Do not take two doses at the same time to make up for a forgotten dose.
If you are uncertain about whether to take a missed dose, contact your healthcare provider or pharmacist.
This is especially important if you take other medications that affect your blood pressure or heart function.
Taking more lisinopril than prescribed can cause your blood pressure to become too low.
Symptoms may include dizziness, weakness, lightheadedness, fainting, or unusual tiredness.
Always take only the amount prescribed.
Do not stop taking lisinopril without speaking with your healthcare provider.
Stopping treatment may allow your blood pressure to rise again or may worsen heart failure.
If your medication needs to be changed, your healthcare provider will tell you how to do so safely.
Your healthcare provider may ask you to check your blood pressure regularly.
Keeping track of your readings can help show whether lisinopril is working and whether your dose needs to be adjusted.
Lisinopril can affect how the kidneys work, especially when treatment is first started or the dose is increased.
Your healthcare provider may order blood tests to check kidney function, including creatinine levels.
People who already have kidney problems may need closer monitoring or a different dose.
Lisinopril can increase the amount of potassium in the blood.
Your healthcare provider may check your potassium level, particularly if you have kidney disease or take potassium supplements, potassium-containing salt substitutes, or medications that can also raise potassium.
Vomiting, diarrhea, heavy sweating, or not drinking enough fluids can cause dehydration.
When you are dehydrated, lisinopril may cause your blood pressure to fall too low or may affect your kidneys.
Contact your healthcare provider if you have significant vomiting or diarrhea while taking the medication.
Lisinopril may sometimes cause dizziness or lightheadedness, particularly when treatment first begins or after the dose is increased.
Stand up slowly after sitting or lying down to give your body time to adjust.
Lisinopril may be prescribed alone or together with other medications.
If you take diuretics, other blood pressure medicines, or medicines for heart disease, your healthcare provider may need to monitor you more closely because the combination can lower blood pressure further.
Take lisinopril once daily at a consistent time, follow your prescribed dose, and attend regular medical appointments.
Regular monitoring of your blood pressure, kidney function, and potassium can help your healthcare provider make sure the medication continues to work safely and effectively.
Prinivil (Lisinopril) is available in the following forms and strength:
Prinivil should not be used during pregnancy because lisinopril can harm an unborn baby, especially during the later stages of pregnancy.
If you become pregnant while taking Prinivil, contact your healthcare provider as soon as possible.
Do not take Prinivil if you are allergic to lisinopril or another ACE inhibitor.
Tell your healthcare provider about any previous serious allergic reaction to this type of medication before starting treatment.
Prinivil can rarely cause angioedema, which is sudden swelling under the skin.
This may affect the face, lips, tongue, or throat and can make breathing difficult. If you have had angioedema from an ACE inhibitor in the past, Prinivil may not be appropriate for you.
Seek emergency medical care if you develop swelling of the face, lips, tongue, or throat.
Prinivil can interact with certain prescription medicines, over-the-counter products, supplements, and herbal products.
Tell your healthcare provider about everything you take, especially other blood pressure medicines, diuretics, potassium supplements, salt substitutes containing potassium, and medicines that can affect kidney function.
Lisinopril can affect kidney function in some people.
You may need closer monitoring if you already have kidney disease, are older, are dehydrated, or take other medicines that can affect the kidneys.
Your healthcare provider may order blood tests to check how well your kidneys are working.
People with conditions such as diabetes, heart disease, or kidney problems may need closer monitoring while taking Prinivil.
Your healthcare provider may adjust your dose based on your blood pressure, kidney function, potassium level, and overall health.
Prinivil may cause low blood pressure, especially when treatment is first started or the dose is increased.
The risk may be higher if you are dehydrated, have low blood volume, or take a high dose of a diuretic.
Symptoms can include dizziness, weakness, lightheadedness, or fainting.
Prinivil may cause dizziness, headache, tiredness, or weakness in some people.
Avoid driving, operating machinery, or doing anything that requires full alertness until you know how the medication affects you.
A persistent dry cough is a known side effect of ACE inhibitors such as lisinopril.
If the cough becomes bothersome or does not go away, talk to your healthcare provider. Another type of blood pressure medicine may be considered if needed.
Prinivil can increase the amount of potassium in your blood, a condition called hyperkalemia.
The risk may be higher if you have kidney disease, diabetes, or take potassium supplements or other medicines that raise potassium levels.
Your healthcare provider may check your blood potassium during treatment.
Some people may be at increased risk of sudden worsening of kidney function while taking Prinivil.
This includes older adults, people with reduced kidney function, people who are dehydrated, and those taking other medicines that affect the kidneys.
Contact your healthcare provider if you develop significant vomiting, diarrhea, or dehydration.
Alcohol can increase the blood-pressure-lowering effect of lisinopril and may make dizziness or lightheadedness worse.
If you drink alcohol, ask your healthcare provider whether it is safe for you and how much is appropriate.
Unlike some other heart and blood pressure medicines, grapefruit juice is not known to have a significant interaction with lisinopril.
However, continue to follow your healthcare provider’s dietary instructions, especially if you have kidney problems or have been advised to limit potassium.
While taking Prinivil, your healthcare provider may monitor your blood pressure, kidney function, and potassium levels.
Regular follow-up helps make sure the medication is working effectively and that any potential problems are detected early.
Lisinopril begins working relatively quickly. Its blood-pressure-lowering effect can start within about 1 hour, with a stronger effect developing over the next several hours. However, the full benefit may take several weeks of regular treatment, so continue taking it exactly as prescribed even if you do not notice an immediate difference.
Prinivil does not usually cause traditional withdrawal symptoms. However, stopping it suddenly may allow your blood pressure to rise again or may worsen heart failure or other heart-related conditions. Do not stop Prinivil without first speaking with your healthcare provider.
Sexual side effects such as reduced sex drive or erectile dysfunction can occur, although they are not among the most common side effects of lisinopril. If you notice persistent changes in sexual function, discuss them with your healthcare provider. Other medical conditions or medications may also contribute.
Prinivil is usually taken once daily, and it can generally be taken at any time of day. Because lisinopril may cause dizziness when you first start treatment, your healthcare provider may suggest taking the first dose at bedtime. After that, choose a time you can follow consistently and take it at about the same time every day.
Lisinopril may begin lowering blood pressure within a few hours after a dose. Its strongest effect from a single dose may occur several hours later, but the overall blood-pressure-lowering benefit can take 2 to 4 weeks to fully develop. If you are taking lisinopril for heart failure, symptom improvement may take several weeks or even longer. Continue treatment as prescribed and attend regular follow-up appointments so your healthcare provider can monitor your progress.
