name: Flomax
Pronounced: FLOW-maks
Generic name: Tamsulosin hydrochloride , Flomax MR ( tamsulosin hydrochloride,
Flomaxtra )
Why is Flomax prescribed?
Flomax 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.
Flomax doesn't shrink the prostate. Instead, it relaxes the muscle
around it, freeing the flow of urine and decreasing urinary symptoms.
Most important fact about Flomax
Flomax can cause dizziness, especially when you first stand up. Be
careful about driving, operating machinery, and performing any other
hazardous task until you know how you react to the drug.
How should you take Flomax?
Take Flomax once daily, half an hour after the same meal each day.
Do not crush, chew, or open the capsule.
--If you miss a dose...
Take it as soon as you remember. If it is almost time for your next
dose, skip the one you missed and go back to your regular schedule.
Do not take 2 doses at once.
If you miss several doses in a row, resume treatment with a dose of
1 capsule daily and check with your doctor on how to proceed.
--Storage instructions...
Store at room temperature.

Why should Flomax not be prescribed?

Special warnings about Flomax
Remember that, in a few men, Flomax can cause a drop in blood pressure
upon first standing up, which in turn can lead to dizziness or fainting.
Avoid driving and other hazardous tasks for 12 hours after your first
dose or a dosage increase, and be careful to stand up slowly until
you're sure the drug won't make you dizzy. If you do become dizzy,
sit down until it passes.
Although the problem is extremely rare (affecting perhaps 1 in 50,000)
Flomax has been known to cause priapism--a painful, persistent erection
unrelated to sexual activity. If you develop this side effect, call
your doctor without delay. The condition can lead to permanent impotence
if not treated immediately.

If Flomax 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 Flomax with any of the following:
