1) What Flomaxtra XL is and what it is used for
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 alpha1A-receptors that cause the muscles in the urethra to
tighten. Flomaxtra XL is an alpha1A-adrenoceptor 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.

2) What you need to know before you use Flomaxtra XL

• are allergic to tamsulosin or any of the other ingredients of
Flomaxtra XL (listed in section 6)

• 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

take appropriate precautions with respect to medication and surgical

postpone or temporarily stop taking this medicine when undergoing eye
surgery because of a cloudy lens (cataract) or increased pressure in the
eye (glaucoma).
