Viagra (sildenafil) is manufactured by Pfizer. It is an established brand that comes from Pfizer’s sildenafil product portfolio.
Yes. While Pfizer manufactures the branded Viagra, sildenafil is also made by multiple companies as generic versions after patent exclusivity ends (or in markets where generics are permitted). In practice, the “manufacturer” on a prescription or bottle depends on whether you’re getting brand Viagra or a specific generic product.
Look at the label on your prescription bottle for the “manufacturer” or “marketed by” name, since generic sildenafil products can come from different manufacturers even when the active ingredient is the same (sildenafil).
