Cenforce 25 mg tablets, which contain sildenafil citrate (the same active ingredient as in Viagra), are not FDA-approved in the United States for over-the-counter or prescription use under the brand name "Cenforce." Here's why: FDA Approval Status: Cenforce is a generic version of sildenafil that is primarily produced by Centurion Laboratories in India. Although sildenafil citrate (the active ingredient in Cenforce) is FDA-approved under the brand name Viagra for the treatment of erectile dysfunction (ED), Cenforce itself does not have FDA approval for sale in the U.S. The FDA has strict regulations on medications that are marketed and sold within the U.S., and Cenforce is not included in their approved list for marketing or use. Generic Versions of Sildenafil: Generic sildenafil Cenforce 25 mg  may be approved by regulatory bodies in other countries, but not necessarily by the FDA in the U.S. Only FDA-approved generics (like Sildenafil by Pfizer or other FDA-approved manufacturers) are allowed to be marketed in the U.S. under specific regulations. Legality in the U.S.: Cenforce is available through online pharmacies and may be imported or sold illegally in the U.S. without the proper FDA oversight. It’s important to be cautious about purchasing medications from unofficial sources, as they may be counterfeit or not meet safety standards. Alternative: Viagra, the brand name for sildenafil, is FDA-approved for the treatment of ED. FDA-approved generics for sildenafil are available in the U.S., which are considered safe and effective when prescribed by a doctor.
