Vidalista 40 mg is the treatment for erectile dysfunction, or ED, one of the most dangerous disorders that plague men. This ED medicine is often given 30 to 60 minutes to an hour prior to having sex. Chew, smash, or break the tablet; instead, swallow the whole thing whole with a glass of water. Use it as needed, with or without food. When a man's erection diminishes at crucial times, Vidalista 40 mg becomes necessary. Thus, the main purpose of Vidalista 40 mg is to make sure that the penis remains erect for a considerable period of time prior to sexual activity. Do not combine the drug with other addictive substances, such as alcohol.
