The Viagra effect for less

From the May 2012 issue of Consumer Reports:   “Viagra (sildenafil) is not slated to become available as a generic until 2019. But sildenafil is also sold as Revatio, a 20-milligram pill for pulmonary arterial hypertension that will become available as a generic in September. (Pfizer makes both drugs.) Men who take the 25-milligram dose of Viagra ($23 a pill) could talk with their doctor about switching to a 20-milligram pill of generic sildenafil (expected to drop to $10 a pill by March 2013). Those who take higher doses of Viagra are better off staying with the branded version for now. But by 2015, generic sildenafil is expected to cost $1 a pill; at that point, men who take 50 or 100 milligrams of Viagra might combine multiple 20-milligram pills of generic sildenafil.”
