Brand names: UroXatral
Uroxatral is used to treat the symptoms of an enlarged prostate—a condition technically known as benign prostatic hyperplasia or BPH. The walnut-sized prostate gland surrounds the urethra (the duct that drains the bladder). If the gland becomes enlarged, it can squeeze the urethra, interfering with the flow of urine. This can cause difficulty in starting urination, a weak flow of urine, and the need to urinate urgently or more frequently. Uroxatral doesn't shrink the prostate. Instead, it relaxes the muscle around it, freeing the flow of urine and decreasing urinary symptoms.
Uroxatral can cause dizziness and even fainting, especially in the first few hours after taking it. Be very careful about driving, operating machinery, or performing dangerous tasks during this period.
Uroxatral should be taken with the same meal each day. Do not crush or chew the tablets.
Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe to continue using Uroxatral.
This side effects list is not complete. If you have any questions about side effects you should consult your doctor. Report any new or continuing symptoms to your doctor right away.
If you have moderate or severe liver problems, you should not use Uroxatral. You should also avoid the drug if you have ever had an allergic reaction to it. Make sure your doctor is aware of any drug reactions you might have experienced.
Benign enlargement of the prostate is not the only condition that can cause male urinary inefficiency and discomfort. Other possibilities include infection, obstruction, cancer of the prostate, and bladder disorders. Before prescribing Uroxatral, your doctor will want to do various tests to determine the cause of your urinary problems.
Stop taking Uroxatral immediately and call your doctor if symptoms of angina pectoris (chest pain due to a heart condition) start or get worse.
Be sure to tell your doctor about any history of electrical problems with your heart (QT prolongation) before you start taking Uroxatral. Also let the doctor know if you have any problems with your kidneys or liver.
If Uroxatral is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Uroxatral with the following:Alpha-blockers (used to treat high blood pressure or BPH) such as carvedilol (Coreg), prazosin (Minipress), doxazosin (Cardura), tamsulosin (Flomax)Atenolol (Tenormin)Cimetidine (Tagamet)Diltiazem (Cardizem)Itraconazole (Sporanox)Ketoconazole (Nizoral)Ritonavir (Norvir)

Any medication taken in excess can have serious consequences. If you suspect an overdose of Uroxatral, seek emergency treatment immediately. Symptoms of an overdose may include low blood pressure.
