Cenforce 100 is a medication primarily used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is the same active ingredient found in Viagra. Sildenafil works by increasing blood flow to the penis, which helps men achieve and maintain an erection during sexual stimulation. Cenforce 100 is available in tablet form and is typically taken orally, usually about 30 minutes to 1 hour before sexual activity. It's important to note that Cenforce 100 should only be used under the guidance of a healthcare professional, as it may not be safe for everyone and can interact with certain medications or medical conditions.
