Sildenafil (Viagra) is a generic prescription erectile dysfunction (ED) medication used for helping men achieve and maintain an erection when sexually aroused. It improves blood flow to the penis for stronger erections. Sildenafil has been helping men overcome ED symptoms since 1998 and is trusted by millions each year for improving confidence in the bedroom.
Sildenafil belongs to a class of medications called PDE5 inhibitors. The PDE5 enzyme is responsible for tightening blood vessels and reducing circulation to stop an erection. Blocking PDE5 allows the blood vessels in the penis to relax and widen so more blood can enter. While Sildenafil does not cause erections, it supports your body’s response to stimulation and helps with achieving and maintaining a firm erection.
Pulmonary arterial hypertension (PAH) patients may also be prescribed Sildenafil. This condition occurs when the blood vessels narrow in the lungs, causing high blood pressure and symptoms like fatigue, dizziness, and shortness of breath. Sildenafil is not a cure for PAH, but it can significantly slow the progression of PAH symptoms and improve quality of life.
Sildenafil is well-tolerated by most men. As the original medication for ED, it has been extensively studied and researched. Not everyone will experience side effects, and clinical reports have found that most side effects are mild and temporary.1 Speak to your physician to find out if Sildenafil is safe for you.

Take Sildenafil by mouth with a glass of water about 30–60 minutes before sexual activity. Sildenafil has a quick onset time of as fast as 15 minutes for some men. After a dose, you will have approximately a 4-hour window where Sildenafil will help you achieve a stronger erection when sexually stimulated. Other tips for maximizing the benefits of Sildenafil:
Sildenafil should never be taken with nitrate medications, which can cause a dangerous drop in blood pressure if combined. Men who have blood pressure conditions, liver or kidney disease, or a history of stroke or heart attack may require strict medical supervision when taking Sildenafil. Other cautions include:
If you experience light-headedness during sex, vision or hearing loss, or a prolonged and painful erection, get medical help right away to reduce the risk of permanent damage. Always speak to your doctor if you have any concerns about Sildenafil.
Common side effects of Sildenafil include:
These effects are typically mild and temporary, with many users experiencing little to no discomfort. However, Sildenafil may cause some rarer but more more serious side effects, including:
If any of these severe side effects occur, seek medical attention immediately. Consult your doctor for a complete and comprehensive list of Sildenafil side effects.
Sildenafil typically lasts 4–6 hours. Depending on food intake and dosage, Sildenafil typically starts working within 30–60 minutes after dosing.
Headache, flushing, and nasal congestion are the most common side effects of Sildenafil. Other side effects may include indigestion, dizziness, and mild vision changes.
Sildenafil is used primarily to treat ED. Because of how it improves blood circulation, some patients with pulmonary arterial hypertension (PAH) are also prescribed Sildenafil.
Yes. Sildenafil and Viagra use the same active ingredient and provide identical benefits. However, Sildenafil is the generic option and is priced considerably lower than its brand-name version.
