Prescription required
Sildenafil is a prescription medication used to treat erectile dysfunction (ED) in men. It works by boosting blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which relax blood vessels and improve circulation. It is taken by mouth as needed, typically 30 minutes to 1 hour before sexual activity, and should not be used more than once per day.
