Tadalista 40 mg is a high-dose formulation of tadalafil, used to treat erectile dysfunction (ED) in men. It contains 40 mg of tadalafil, a PDE5 inhibitor, which works by relaxing the blood vessels in the penis, increasing blood flow during sexual arousal and helping men achieve and maintain a firm erection. Common side effects may include headache, back pain, muscle aches, flushing, and upset stomach. These are generally mild and temporary. Serious side effects, such as priapism (prolonged erection), vision changes, or chest pain, require immediate medical attention.
