Vidalista CT 20 mg is a chewable tablet used to treat erectile dysfunction (ED) in men. It contains Tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor that increases blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. It is taken as needed, not daily, and should not be used more than once every 24 to 36 hours. Common side effects may include headache, flushing, nasal congestion, back pain, indigestion, or dizziness. The chewable form may increase palatability but doesn’t reduce the risk of side effects.
