Tadaflo 20 mg is a medication that contains Tadalafil, which is primarily used to treat erectile dysfunction (ED) and, in some cases, benign prostatic hyperplasia (BPH). Tadalafil works by relaxing the blood vessels in the penis, increasing blood flow and helping to achieve and maintain an erection during sexual stimulation. Its effects can last up to 36 hours, allowing for greater spontaneity in sexual activity. For BPH, Tadaflo 20 mg helps to relieve symptoms such as difficulty in starting the flow of urine, weak stream, and the need to urinate frequently or urgently.
