Tadalista Professional is a medication used to treat erectile dysfunction (ED) in men. It contains Tadalafil, a PDE5 inhibitor, that helps increase blood flow to the penis during sexual arousal, allowing men to achieve and maintain an erection. Common side effects include headache, dizziness, flushing, indigestion, and muscle aches. More serious side effects such as vision problems, chest pain, or priapism (a prolonged erection lasting more than 4 hours) are rare, but should be addressed immediately with medical attention.
