01The 50 mg name on two cartons

It is not a United States Viagra NDC. The recommended starting dose of sildenafil for most patients is 50 mg, used as needed about 1 hour before sexual activity.

The dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day. Sexual stimulation is required. Viagra is not indicated for women.

VIAGRA tablets contain sildenafil citrate equivalent to 25 mg, 50 mg, or 100 mg of sildenafil. VIAGRA is supplied as blue, film-coated, rounded-diamond-shaped tablets.

02The hour written on the U.S. label

VIAGRA may be taken anywhere from 30 minutes to 4 hours before sexual activity. Most studies assessed the efficacy of VIAGRA approximately 60 minutes post dose. Both sildenafil and the metabolite have terminal half lives of about 4 hours.

This site’s sildenafil brief locks 100 mg.

03Nitrate stop

Sildenafil is contraindicated in patients using any form of organic nitrate, either regularly or intermittently. Do not combine with other PDE5 inhibitors.
