Cialis is a prescription medication primarily used to treat erectile dysfunction (ED) and symptoms of benign prostatic hyperplasia (BPH) in men. Its active ingredient, tadalafil, works by increasing blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. Cialis is known for its long-lasting effect, up to 36 hours, earning it the nickname “the weekend pill.” It should be taken as directed by a healthcare professional, and is not suitable for everyone, especially those with certain heart conditions. Side effects may include headache, indigestion, back pain, or muscle aches, which usually subside.
