Doxazosin is used to treat high blood pressure and/or benign protatic hyperplasia (BPH). The prostate is one of the main components of the male reproductive system and plays a vital role in the development of the male sex organs. In adult men, its main function is to add important fluids to the semen supplying nourishment to the sperm during ejaculation. This protects the semen against naturally occurring acids located within the vagina. In many men, the prostate begins to grow when they are in their 50s and usually continues to grow throughout the rest of their lives. As the prostate grows, it puts pressure on the urethra. As pressure builds, it may lead to bothersome urinary symptoms and future complications. This condition is known as enlarged prostate, or benign prostatic hyperplasia (BPH), and is a noncancerous enlargement of the prostate. Although enlarged prostate is not life threatening, it does require long-term management by both you and your doctor. There are several treatment options available to men with enlarged prostate (BPH).
Doxazosin side effects, that may go away during treatment, include dizziness, headache, nausea, drowsiness, lack of energy, dry mouth, or nasal congestion. If Doxazosin side effects continue or are bothersome, check with your doctor. CONTACT YOUR DOCTOR IMMEDIATELY if you experience Doxazosin side effects like chest pain, swelling of hands or feet, ringing in the ears, blurred vision, decreased sexual ability, easy bleeding or bruising, or irregular or unusually fast heartbeat. IF YOU EXPERIENCE Doxazosin side effects like difficulty breathing; tightness of chest; swelling of eyelids, face, or lips; or if you develop a rash or hives, tell your doctor immediately. Do not take any more doses of this medicine unless your doctor tells you to do so. If you notice other Doxazosin side effects not listed above contact your doctor, nurse, or pharmacist.
