Viagra (sildenafil) is a prescription drug used to treat erectile dysfunction (ED). It belongs to a class of medications known as phosphodiesterase-5 inhibitors (PDE5-Is). It works by increasing the blood flow to the penis, allowing for an erection.
Sildenafil is usually taken orally as a tablet and should be taken about an hour before sexual activity. It can also be taken once a day if prescribed by a doctor. Sildenafil is sometimes used off-label to treat secondary Reynaud phenomenon, female sexual arousal disorder, and as an adjunct in the treatment of altitude-induced hypoxemia.
Viagra may be used alone or in combination with other medications to treat erectile dysfunction. However, you should consult your doctor before taking Viagra with other medications, as some medications may interact with it and cause dangerous side effects. Additionally, if you are taking any nitrate medications, it is important to avoid taking Viagra, as this can cause a dangerous drop in blood pressure.
Sildenafil should be taken about an hour before sexual activity but can be taken up to 4 hours before. It should not be taken more than once a day. Sildenafil can be taken with or without food but taking it with a high-fat meal may delay its effects. Certain health conditions and medications may require a lower dosage or that you take sildenafil less often than once a day. If you are unsure about how to take sildenafil, talk to your doctor or pharmacist for more information.
The recommended starting dose of sildenafil for Erectile Dysfunction (ED) is 50 mg, taken as needed approximately 1 hour before sexual activity. The dose can be adjusted depending on the patient’s response, with a maximum dose of 100 mg per day and a minimum dose of 25 mg per day. The onset of action can occur within 30 minutes, and the effects can last up to 18 hours. Patients should not exceed the maximum dosing frequency once daily.
