Since none of my wife's uncles were stil lving, we tested 4 of her known 1st cousins to see if we could uncover the mystery. One of my wife's male 1st cousins is now showing as a Close family - 1st cousin match and I suspect that he and the new cousin are really half-siblings.
Your healthcare provider will tell you how much VIAGRA to take and when to take it. Do not take VIAGRA more than once a day. VIAGRA usually starts to work within 30-60 minutes. You may take it up to 4 hours before sexual activity.
A Stacy Wiegman, PharmD, Pharmacy, answered. The recommended dose of Viagra to treat erectile dysfunction is 50 mg taken one hour before sexual activity. However, some men are able to take Viagra from 30 minutes to four hours before sexual activity. Talk to your doctor about the best timing for you.
