VIAGRA (active ingredient: sildenafil) is a prescription medication used to treat erectile dysfunction (ED). Erectile dysfunction is a condition in which a man has difficulty getting or maintaining an erection firm enough for sexual activity.

VIAGRA was developed by Pfizer, a global pharmaceutical company. The medication was originally studied in the late 1980s as a potential treatment for angina (chest pain) and high blood pressure. During clinical trials, researchers discovered that sildenafil had a significant effect on erectile function. Based on these findings, Pfizer shifted its focus and developed VIAGRA as a treatment for erectile dysfunction.

VIAGRA belongs to a group of medications called phosphodiesterase type 5 (PDE5) inhibitors. These medications work by increasing blood flow to the penis during sexual stimulation, making it easier to achieve and maintain an erection.

Treatment of Erectile Dysfunction (ED)

VIAGRA is used to help men with erectile dysfunction improve their ability to get and keep an erection suitable for sexual activity.

It is important to understand that VIAGRA does not cause an automatic erection. Sexual stimulation is still required for the medication to work.

Key Benefits of VIAGRA

  • Helps improve erectile function.
  • Makes it easier to achieve and maintain an erection.
  • Works in response to sexual stimulation.
  • May help improve confidence and sexual satisfaction.

How VIAGRA Works

VIAGRA works by blocking an enzyme called phosphodiesterase type 5 (PDE5). This action relaxes blood vessels and increases blood flow to the penis during sexual arousal.

By improving blood flow, VIAGRA helps support a natural erectile response when sexual stimulation occurs.

VIAGRA should be taken exactly as prescribed by your healthcare provider. For most men, the medication is taken as needed about 1 hour before sexual activity. However, VIAGRA may be taken anywhere from 30 minutes to 4 hours before sexual activity, depending on your individual response to the medication.

VIAGRA can be taken with or without food. However, taking it with a high-fat meal may delay how quickly the medication begins to work. If you want the fastest possible effect, taking VIAGRA on an empty stomach or after a light meal may be helpful.

Certain medical conditions, age-related factors, or medications may affect the dose that is right for you. Your healthcare provider may recommend a lower dose or adjust how often you take the medication based on your individual needs.

Recommended Dosage for Erectile Dysfunction (ED)

Adults

  • Recommended starting dose: 50 mg taken as needed
  • Take approximately 1 hour before sexual activity
  • May be taken anywhere from 30 minutes to 4 hours before sexual activity
  • Dose may be decreased to 25 mg or increased to 100 mg based on effectiveness and tolerability
  • Maximum recommended dose: 100 mg per day
  • Do not take more than one dose within a 24-hour period

When Will VIAGRA Start Working?

VIAGRA may begin working within 30 minutes of taking a dose. However, the exact timing can vary from person to person.

Sexual stimulation is required for VIAGRA to work. The medication does not cause an automatic erection and will only help you achieve an erection when you are sexually aroused.

How Long Do the Effects Last?

The effects of VIAGRA can last for several hours. Some men may continue to experience benefits for up to 18 hours after taking a dose, although the strength of the effect gradually decreases over time.

If you have questions about how to take VIAGRA or what dose is right for you, speak with your healthcare provider or pharmacist for guidance.

  • Diarrhea
  • Difficulty falling asleep or staying asleep
  • Flushing (feeling of warmth)
  • Headache
  • Heartburn
  • Muscle aches
  • Nosebleeds
  • Numbness, burning, or tingling in the arms, hands, feet, or legs

  • Fainting
  • Itching or burning during urination
  • Rash

Viagra and its generic alternative Sildenafil are available in the following forms and strengths:

  • 25 mg
  • 50 mg
  • 100 mg

Sildenafil: Tablet

  • 25 mg
  • 50 mg

Before taking VIAGRA, tell your healthcare provider if you are allergic to sildenafil, any other medications, or any of the ingredients in VIAGRA. If you are unsure whether you have an allergy to any ingredient, your pharmacist can provide a complete list of ingredients.

Do not take VIAGRA if you are taking riociguat (Adempas) or any medication that contains nitrates. Common nitrate medications include nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Taking VIAGRA with these medications can cause a sudden and dangerous drop in blood pressure, which may lead to dizziness, fainting, heart attack, or stroke.

Sildenafil is also available in products used to treat pulmonary arterial hypertension (PAH). If you are pregnant, planning to become pregnant, or breastfeeding, discuss the benefits and risks of treatment with your healthcare provider before using sildenafil. If you become pregnant while taking sildenafil, contact your healthcare provider as soon as possible.

Do not take more VIAGRA than prescribed. Doses higher than 100 mg have not been shown to improve effectiveness and may increase the risk of side effects.

The most common side effects of VIAGRA include:

  • Headache
  • Facial flushing
  • Upset stomach or indigestion
  • Nasal congestion
  • Back pain
  • Muscle pain
  • Nausea
  • Dizziness
  • Skin rash

Although these side effects are usually mild, contact your healthcare provider if they become severe, persistent, or bothersome.

VIAGRA may occasionally affect vision. Some people have reported changes in color vision, increased sensitivity to light, or blurred vision while taking sildenafil. In rare cases, sildenafil has also been associated with hearing problems, including sudden hearing loss. Seek medical attention immediately if you experience sudden vision changes, hearing loss, ringing in the ears, or a significant decrease in hearing.

Always tell your healthcare provider about all prescription medications, over-the-counter products, vitamins, and herbal supplements you take before starting VIAGRA. This can help reduce the risk of drug interactions and side effects.

How Should I Store VIAGRA?

Store VIAGRA in its original container with the lid tightly closed. Keep the medication at room temperature and protect it from excess heat and moisture. Avoid storing it in the bathroom, where humidity levels can be high. Always keep VIAGRA out of the reach of children and pets to help prevent accidental ingestion.

What Other Information Should I Know?

Keep all scheduled appointments with your healthcare provider while using VIAGRA. These visits allow your healthcare provider to monitor your treatment and address any questions or concerns you may have. Do not share VIAGRA with anyone else, even if they have symptoms similar to yours. The medication has been prescribed specifically for your individual health needs and may not be safe or appropriate for another person. If you need a prescription refill or have questions about your medication, speak with your pharmacist or healthcare provider for assistance.

Is VIAGRA Safe?

VIAGRA is generally considered safe when taken exactly as prescribed by a healthcare provider. Its safety and effectiveness have been evaluated in clinical trials and supported by more than 20 years of medical use. Like all medications, VIAGRA can cause side effects and may not be suitable for everyone. Before starting treatment, discuss your medical history, current medications, and any health concerns with your healthcare provider to ensure that VIAGRA is an appropriate option for you.
