Vidalista Professional is a medication that men with erectile dysfunction can take. Tadalafil, an inhibitor of phosphodiesterase type 5, is one of its constituents. It usually occurs 30–60 minutes before sexual activity, and its effects can last up to 36 hours. Store the drug at room temperature. Avoid being in the sun. After taking a dose, avoid taking more than one pill in 24 hours. Never break or chew the prescription drug. It is possible to take it orally together with a glass of water. However, you should always swallow the drug whole rather than trying to chew or shatter it.
