Vidalista 20mg is a generic version of Cialis, which is a medication used to treat erectile dysfunction (ED) in men. It is often referred to as the "weekend pill" because it can last for up to 36 hours. This means that you can take it once and have the ability to get an erection for multiple sexual encounters over the course of a weekend.

Vidalista 20 works by increasing blood flow to the penis, which helps men to get and maintain an erection. It does this by blocking the action of an enzyme called phosphodiesterase-5 (PDE5). PDE5 breaks down cGMP, which is a chemical that helps to relax the blood vessels in the penis. By blocking the action of PDE5, tadalafil allows more cGMP to build up, which leads to increased blood flow to the penis and an erection.

Vidalista 20mg is generally well-tolerated, but it can cause some side effects, such as headache, flushing, upset stomach, and back pain. These side effects are usually mild and go away on their own. In rare cases, tadalafil can cause more serious side effects, such as a sudden decrease in blood pressure or a heart attack. If you experience any serious side effects, you should stop taking Vidalista 20mg and seek medical attention immediately.
