Vidalista is a widely used medication for treating erectile dysfunction (ED) in men. Its active ingredient is Tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil helps increase blood flow to the penis during sexual stimulation, enabling men to achieve and maintain an erection. Common side effects include headache, flushing, nasal congestion, back pain, indigestion, and muscle aches. Serious side effects like chest pain, vision loss, or an erection lasting more than 4 hours (priapism) require immediate medical attention.
