Cenforce 100 mg, which contains sildenafil citrate, is primarily manufactured in India by Centurion Laboratories. While it is widely available in India and sold through online pharmacies globally, it is not officially approved by major regulatory agencies like the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA). However, some countries allow its use under personal importation laws for individual treatment with a valid prescription. In places like the UK, Canada, and Australia, Cenforce may be available through certain online channels, but it is not formally listed as an approved drug by their national health authorities. Always consult a healthcare provider before use.
