VIAGRA (sildenafil citrate) was developed by Pfizer, a global pharmaceutical company. It was originally researched in the late 1980s as a potential treatment for angina (chest pain) and high blood pressure. However, during clinical trials, researchers noticed that the drug was more effective at improving erectile function. As a result, Pfizer shifted its focus and pursued VIAGRA as a treatment for erectile dysfunction (ED).
VIAGRA (active ingredient: sildenafil) is a prescription medication indicated for the treatment of ED. ED is when a man has trouble getting or keeping an erection for sexual activity.
VIAGRA belongs to a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors. These medications help improve blood flow to the penis, making it easier to get an erection with sexual stimulation.
VIAGRA (sildenafil) should be taken about an hour before sexual activity. It can be taken up to 4 hours before but should not be used more than once a day. VIAGRA can be taken with or without food, but a high-fat meal may delay its effects. Some health conditions and medications may require a lower dose or less frequent use. If you are unsure how to take VIAGRA, talk to your healthcare provider.
The usual starting dose for erectile dysfunction (ED) is 50 mg, taken as needed about 1 hour before sexual activity. The dose can be adjusted based on response, with a minimum of 25 mg and a maximum of 100 mg per day. VIAGRA starts working within 30 minutes, and its effects can last up to 18 hours. Do not take more than one dose in 24 hours.
Viagra and its generic alternative Sildenafil are available in the following forms and strengths:
Tell your healthcare provider if you are allergic to VIAGRA (sildenafil), any other medications, or any ingredients in VIAGRA products. Your pharmacist can provide a list of ingredients to help you avoid potential allergic reactions.
Do not take VIAGRA if you are using or have recently used Riociguat (Adempas) or nitrates. Nitrates include isosorbide dinitrate (Isordil), isosorbide mononitrate (Monoket), and nitroglycerin (Minitran, Nitro-Dur, Nitromist, Nitrostat). Taking VIAGRA with these medications can cause a serious drop in blood pressure.
VIAGRA is used to treat pulmonary arterial hypertension (PAH) in women. If you are pregnant, planning to become pregnant, or breastfeeding, tell your healthcare provider before taking VIAGRA. If you become pregnant while using it, contact your healthcare provider immediately.
Doses higher than 100 mg do not increase effectiveness but may raise the risk of side effects. The most common side effects of sildenafil include headache, flushing, upset stomach, nasal congestion, back pain, muscle pain, nausea, dizziness, and rash. About 2% of patients experience these side effects.
Sildenafil has been linked to vision changes, including color perception, light sensitivity, and blurred vision. In rare cases, it has been associated with hearing loss (ototoxicity), which may be reversible in some patients.
Keep VIAGRA in its original container, tightly closed, and out of reach of children. Store the tablets at room temperature, away from heat and moisture.
Keep all appointments with your healthcare provider. Do not share VIAGRA with others. If you have questions about refilling your prescription, ask your pharmacist.
VIAGRA is safe when taken as prescribed. Its safety has been studied in clinical trials and confirmed through over 20 years of medical use.
