About Viagra

Viagra is a phosphodiesterase-5 (PDE5) inhibitor, which works by relaxing muscles found in the walls of blood vessels to increase blood flow.

Viagra is used to treat erectile dysfunction (ED) and impotence in men. Viagra is available only by prescription. The generic medication is known as sildenafil.

Viagra may be prescribed as a tablet. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.

If you are prescribed Viagra, be sure to complete the full course of the ED medication unless your doctor specifically tells you to stop. If you don’t complete your prescription, the ED medication may not fully treat your erectile dysfunction.

Viagra uses

There are several FDA-approved uses for Viagra, but your healthcare provider may also prescribe it off-label to treat other medical conditions.

Your doctor may prescribe Viagra for any of the following reasons, or other reasons not listed here. If you have questions about why a medication is prescribed, ask your online doctor or pharmacist.

  • Erectile dysfunction (ED)

    Viagra is FDA-approved to treat erectile dysfunction and impotence in men.

    Another brand of sildenafil, Revatio, is used to treat pulmonary arterial hypertension (high blood pressure) and improve exercise capacity in men and women. This page contains specific information for Viagra, not Revatio.

How to take Viagra

Your pharmacist will provide you with instructions on how to take your Viagra prescription. Be sure to read your prescription label and follow the instructions. Call your doctor or pharmacy if you have any questions.

Viagra can come in different doses, so be sure to follow the specific instructions on your prescription. This medication usually comes in the form of a tablet.

General instructions may include:

  • Viagra is typically taken when needed, 30 minutes to one hour before sexual activity.

  • You may take it up to four hours before sexual activity.

  • Do not take Viagra more than once per day.

What to avoid while taking Viagra

Viagra has 312 drug interactions. Don’t change what you are taking without checking with your doctor or pharmacist. That includes other medications or supplements, as well as over-the-counter medicines. 

Possible drug interactions with Viagra include:

  • Medications used to treat high blood pressure or a prostate disorder

  • Antibiotics, such as clarithromycin, erythromycin, or telithromycin

  • Antifungal medications

  • Medicine used to treat HIV and AIDs

  • Medications used to treat pulmonary arterial hypertension

  • Nitrates


Do not take Viagra with nitrate medicine. When taken together, these medications can cause a sudden and serious decrease in blood pressure.

Viagra may cause low blood pressure, and drinking alcohol may increase this effect. Talk to your healthcare provider before drinking alcohol. Drinking grapefruit juice with Viagra may lead to unwanted side effects.

Medication alternatives to Viagra

If your healthcare provider prefers to put you on another treatment altogether, they may suggest other ED medications in another drug class. Here are some common doctor-recommended alternatives based on your health issue:
