Viagra is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, viagra works by increasing blood flow to the penis to help a man get and keep an erection. Viagra does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). Practice “safe sex” such as using latex condoms. Consult your doctor or pharmacist for more details.

How to use viagra Tablet

Read the Patient Information Leaflet provided by your pharmacist before you start taking viagra and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

To treat erectile dysfunction-ED, take viagra by mouth as directed by your doctor, usually as needed. Take sildenafil at least 30 minutes, but no more than 4 hours, before sexual activity (1 hour before is the most effective). Do not take more than once daily.

A high-fat meal may delay how quickly viagra begins to work.

The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
