Sildigra 100 mg is a brand name for a generic version of sildenafil citrate, which is commonly used to treat erectile dysfunction (ED) in men. Sildenafil works by increasing blood flow to the penis during sexual arousal, helping men achieve and maintain an erection. Common side effects may include headaches, flushing, indigestion, dizziness, and nasal congestion. Less common but serious side effects can include vision changes or sudden loss of vision, chest pain, or priapism (a prolonged and painful erection).
