What is Flomaxtra XL
Erythromycin, an antibiotic used to treat infections
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.
Please inform your doctor that you are on Flomaxtra XL before any
operation or dental procedure as there is a potential that your
medicine may interfere with the effects of the anaesthetic.
What is in this leaflet:
4. Possible side effects
1. WHAT FLOMAXTRA XL IS AND WHAT IT IS USED FOR
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
Pregnancy, breast-feeding and fertility
Flomaxtra XL is not indicated for use in women.
In men, abnormal ejaculation has been reported (ejaculation
disorder). This means that the semen does not leave the body via
the urethra, but instead goes into the bladder (retrograde
ejaculation) or the ejaculation volume is reduced or absent
(ejaculation failure). This phenomenon is harmless.

There is no information available on whether Flomaxtra XL affects
the ability to drive or to operate machinery or equipment. However,
it is known that Flomaxtra XL may cause drowsiness, blurred vision,
dizziness and fainting. If you suffer from these do not drive or

have ever fainted or felt dizzy when suddenly sitting or

down straight away until the symptoms have disappeared.
