Different types of #Tadalafil medication are available and it is important to understand how to take them before taking them. Dosage, uses and common side effects vary depending on the type of Tadalafil medication. Tadalafil comes in tablet form and should be swallowed whole with a glass of water. The dosage for erectile dysfunction (ED) is usually 10 mg or 20 mg taken as needed about an hour before sexual activity. The maximum dose per day is 40 mg. If you have liver problems, your doctor may prescribe a lower dose or advise against taking tadalafil altogether. Tadalfil can also be used to treat benign prostatic hyperplasia (BPH), which is an enlarged prostate gland that can cause urinary problems such as difficulty starting urination, weak stream, getting up often at night to urinate, dribbling after urination and having to go urgently (nocturia). For BPH the usual dosage is 5 mg daily taken at the same time each day #health
