Tadact 20 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It contains the active ingredient tadalafil, which belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Tadalafil works by increasing blood flow to the penis during sexual stimulation, which helps to achieve and maintain an erection. Tadact 20 mg tablets are typically taken orally, with or without food, as directed by a healthcare provider. The recommended dosage may vary depending on individual factors such as the severity of erectile dysfunction and the individual's response to the medication.
