What is Flomaxtra XL
Flomaxtra XL contains the active substance tamsulosin hydrochloride. It acts by relaxing the
muscles in the prostate and urethra (the tube that carries urine to the outside), and lets
urine pass more readily through the urethra and aids urination.
In the prostate gland, bladder and urethra there are specialised cells containing alpha1Areceptors that cause the muscles in the urethra to tighten. Flomaxtra XL is an alpha1Aadrenoceptor blocker, which reduces the action of these specialised cells and relaxes the
muscles making it easier to pass water.
What Flomaxtra XL is used for
Flomaxtra XL is used to treat the symptoms associated with benign prostatic hyperplasia
(BPH) which is enlargement of the prostate gland.
These symptoms include difficulty in starting to pass water, frequent trips to the toilet to
pass water, a feeling of not completely emptying the bladder and having to get up several
times in the night to pass water.
Do not use Flomaxtra XL if you
• are allergic to tamsulosin or any of the other ingredients of Flomaxtra XL (listed in
section 6)
• have a severe liver condition
• have ever fainted or felt dizzy when suddenly sitting or standing up. Dizziness can
sometimes occur when taking Flomaxtra XL, particularly if you are also taking other
alpha1- blockers. If you do feel weak or dizzy make sure you sit or lie down straight away
until the symptoms have disappeared.
Warnings and precautions
Talk to your doctor before using Flomaxtra XL
• If you have kidney problems
• If you are undergoing or have been scheduled for eye surgery because of cloudiness of
the lens (cataract) or increased pressure in the eye (glaucoma).
Please inform your eye specialist that you have previously used, are using or are planning
to use tamsulosin hydrochloride. The specialist can then take appropriate precautions with
respect to medication and surgical techniques to be used. Ask your doctor whether or not
you should postpone or temporarily stop taking this medicine when undergoing eye surgery
because of a cloudy lens (cataract) or increased pressure in the eye (glaucoma).
