Cenforce 25 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection. It's important to note that Cenforce 25 mg should be taken as directed by a healthcare professional, typically about 30 minutes to 1 hour before sexual activity. The effects of the medication usually last for about 4 to 6 hours.
