What is Tadalafil?
Tadalafil is a medication used to treat erectile dysfunction, the inability to get or keep an erection. Erectile dysfunction, sometimes called impotence, has several causes. Causes of erectile dysfunction include heart disease, high blood pressure, diabetes, low testosterone, stress, depression, and most commonly being due to a narrowing of the arteries that take blood to the penis. Tadalafil is a phosphodiesterase (PDE) inhibitor which helps to relax and widen blood vessels and improves the flow of blood. In erectile dysfunction, it increasing blood flow to the penis during sexual stimulation can help to cause and maintain an erection.
Benefits of Tadalafil
Tadalafil is also used for symptoms of benign prostatic hyperplasia (BPH), an enlarged prostate, which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency in adult men. Tadalafil has the ability to make these symptoms less severe and reduce the chance that prostate surgery will be needed. The FDA has approved Tadalafil for treatment of BPH.
Tadalafil is also used in men and women to treat the symptoms of pulmonary arterial hypertension (PAH). This is a high blood pressure that occurs in the main artery that carries blood from the right side of the heart (the ventricle) to the lungs. Tadalafil is used to improve the ability to exercise in people with PAH, which can cause shortness of breath, dizziness, and tiredness.
Side Effects of Tadalafil
Use Tadalafil exactly as directed by your doctor. Do not use more than prescribed. If too much is used, the chance of side effects or other problems is increased. Do not use Tadalafil if you are also using a nitrate drug for chest pain or heart problems. This includes Nitroglycerin, Isosorbideinitrate, and Isosorbide Mononitrate. Taking Tadalafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure.
