Vidalista is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient tadalafil, which works by increasing blood flow to the penis and helping men to achieve and maintain an erection. Vidalista is taken orally, usually 30 minutes before sexual activity. It can be taken with or without food, and its effects can last up to 36 hours. It is important to note that Vidalista does not cure ED, but only helps to temporarily improve symptoms.
