Tadarise 10 mg is commonly marketed as a medicine containing tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED). Tadalafil works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. For tadalafil used as needed for ED, 10 mg is a commonly recommended starting dose. Depending on effectiveness and tolerability, a healthcare professional may adjust the dose. It should generally not be taken more than once in 24 hours. Tadalafil may remain effective for up to 36 hours, although this does not mean an erection will last continuously.
