Doxazosin is one of a group of medicines called alpha-blockers. It is used to treat high blood pressure, or the symptoms caused by enlargement of the prostate gland in men.
Doxazosin can be used to treat high blood pressure (hypertension), by relaxing blood vessels so that blood passes through them more easily. This helps to lower blood pressure.
In patients with an enlarged prostate gland, doxazosin is taken to treat poor and/or frequent passing of urine. This is common in patients with an enlarged prostate gland. Doxazosin works by relaxing muscle around the bladder exit and prostate gland so urine is passed more easily.
Talk to your doctor or pharmacist before taking Doxazosin if:
If you are undergoing eye surgery because of cataract (cloudiness of the lens) please inform your eye specialist before the operation that you are using or have previously used Doxazosin. This is because Doxazosin may cause complications during the surgery which can be managed if your specialist is prepared in advance. Before starting treatment with Doxazosin your doctor may perform tests to rule out other conditions such as prostate cancer that may cause the same symptoms as benign prostatic hyperplasia (enlargement of the prostate gland).
Persistent painful erections may occur very rarely. If this happens you should contact a doctor immediately.
When you start to take Doxazosin you may experience faintness or dizziness caused by low blood pressure, when getting up from sitting or lying down. If you feel faint or dizzy, you should sit or lie down until you feel better and avoid situations where you might fall or hurt yourself. Your doctor may want to measure your blood pressure regularly at the start of therapy to reduce the possibility of these effects happening.
Doxazosin is not recommended for use in children or adolescents below 18 years as safety and efficacy have not yet been established. Benign prostate hyperplasia is not relevant in children.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. There are some medicines that may interact with Doxazosin. Ask your doctor or pharmacist before use if you are taking any of these medicines as they may change the effect of Doxazosin.
Please refer to section 3.
