Tadagra 20 mg is a medication that contains tadalafil, used primarily to treat erectile dysfunction (ED) in men. Tadalafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing blood vessels in the pill, which allows increased blood flow during physical stimulation, helping men achieve and maintain an erection. Common side effects may include headache, flushing, nasal congestion, and upset stomach.
