While a single tablet of Viagra is priced as high as $70 in the United States, generic drugs like sildenafil tablets are available for as little as $3 each when purchased online. Even though the active ingredients are the same, if you’re switching from Pfizer’s brand-name Viagra to a generic form of sildenafil, it’s important to check that you’re purchasing tablets with a similar dosage to the one your healthcare provider prescribed. Sildenafil may also be sold under different brand names in other countries.
