1) What Xalacom is and what it is used for
Xalacom contains two medicines: latanoprost and timolol. Latanoprost
belongs to a group of medicines known as prostaglandin analogues.
Timolol belongs to a group of medicines known as beta-blockers.
Latanoprost works by increasing the natural outflow of fluid from the
eye into the bloodstream. Timolol works by slowing the formation of
fluid in the eye.
Xalacom is used to reduce the pressure in your eye if you have
conditions known as open angle glaucoma or ocular hypertension.
Both these conditions are linked to an increase in the pressure within
your eye, eventually affecting your eyesight. Your doctor will usually
prescribe you Xalacom when other medicines have not worked

2) What you need to know before you use Xalacom
Xalacom can be used in adult men and women (including the elderly),
but is not recommended for use if you are less than 18 years of age.
Do not use Xalacom eye drops solution:
• if you are allergic (hypersensitive) to either of the medicines in
Xalacom (latanoprost or timolol), beta-blockers, or any of the other
ingredients of Xalacom (listed in section 6)
• if you have now or have had in past respiratory problems such as
asthma, severe chronic obstructive bronchitis (severe lung disease
which may cause wheeziness, difficulty in breathing and/or longstanding cough)
• if you have serious heart problems or heart rhythm disorders
• if you are pregnant (or trying to become pregnant)
• if you are breast feeding

tightness, breathlessness or choking), heart failure, low blood
• disturbances of heart rate such as slow heart beat
• breathing problems, asthma or chronic obstructive pulmonary
• poor blood circulation disease (such as Raynaud’s disease or
Raynaud’s syndrome)
• diabetes as timolol may mask signs and symptoms of low blood
• overactivity of the thyroid gland as timolol may mask signs and
• you are about to have any kind of eye surgery (including cataract
surgery) or have had any kind of eye surgery in the past
• you suffer from eye problems (such as eye pain, eye irritation, eye
inflammation or blurred vision)
• you know that you suffer from dry eyes

instructions for contact lens wearers in section 3
• you know that you suffer from angina (particularly a type known as
Prinzmetal angina)
• you know that you suffer from severe allergic reactions that would
usually require hospital treatment
• you have suffered or are currently suffering from a viral infection of
the eye caused by the herpes simplex virus (HSV)

Xalacom with food and drink
Normal meals, food or drink have no effect on when or how you
should use Xalacom.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or
are planning to have a baby, ask your doctor for advice before taking
this medicine.
Latanoprost and timolol have been found to have no effect on male or
female fertility in animal studies.
Driving and using machines
When you use Xalacom your vision may become blurred for a short
time. If this happens to you, do not drive or use any tools or machines
until your vision becomes clear again.
Xalacom contains benzalkonium chloride
Xalacom contains a preservative called benzalkonium chloride. This
preservative may cause eye irritation or disruption to the surface of
the eye. It can be absorbed by contact lenses and is known to
discolour soft contact lenses. Therefore, avoid contact with soft
contact lenses. See the instructions for contact lens wearers in section

3) How to use Xalacom
Always use this medicine exactly as your doctor or pharmacist has
told you. Check with your doctor or pharmacist if you are not sure.
The recommended dose for adults (including the elderly) is one drop
once a day in the affected eye(s).
Do not use Xalacom more than once a day, because the effectiveness
of the treatment can be reduced if you administer it more often.
Use Xalacom as instructed by your doctor until your doctor tells you to
Your doctor may want you to have extra checks on your heart and
circulation if you use Xalacom.
Contact lens wearers
If you wear contact lenses, you should remove them
before using Xalacom. After using Xalacom you
should wait 15 minutes before putting your contact
lenses back in.

7. After using Xalacom, press a finger into the corner of your eye, by
the nose (figure 4) for 2 minutes. This helps to stop latanoprost +
timolol getting into the rest of the body.

Tell your doctor before you have an operation that you are using
Xalacom as timolol may change effects of some medicines used
during anaesthesia.
Other medicines and Xalacom
Tell your doctor or pharmacist if you are taking, have recently taken or
might take any other medicines, including using eye drops and
medicines obtained without a prescription.
Xalacom can affect or be affected by other medicines you are using,
including other eye drops for the treatment of glaucoma. Tell your
doctor if you are using or intend to use medicines to lower blood
pressure, heart medicine or medicines to treat diabetes.
In particular, speak to your doctor or pharmacist if you know that you
are taking any of the following types of medicine:

If you use Xalacom with other eye drops
Wait at least 5 minutes between using Xalacom and using the other
eye drops.
If you use more Xalacom than you should
If you put too many drops in your eye you may experience some
minor irritation in your eye and your eyes may water and turn red. This
should pass but if you are worried contact your doctor for advice.

If you swallow Xalacom
If you swallow Xalacom accidentally you should contact your doctor
for advice. If you swallow a lot of Xalacom you may feel sick, have
stomach pains, feel tired, flushed and dizzy and start to sweat.
If you forget to use Xalacom
Carry on with the usual dosage at the usual time. Do not take a
double dose to make up to the dose you have forgotten. If you are
unsure about anything talk to your doctor or pharmacist.

4) Possible side effects
Like all medicines this medicine can cause side effects, although not
everybody gets them.
You can usually carry on taking the drops, unless the effects are
serious. If you're worried, talk to a doctor or pharmacist. Do not stop
using Xalacom without speaking to your doctor.
Listed below are the known side effects of using Xalacom. The most
important side-effect is the possibility of a gradual, permanent change
in your eye colour. It is also possible that Xalacom might cause
serious changes in the way your heart works. If you notice changes in
your heart rate or heart function you should speak to a doctor and tell
them you have been using Xalacom.
The following are known side effects of using Xalacom:

have eyes of one colour (blue, grey, green or brown eyes). Any
changes in your eye colour may take years to develop. The colour
change may be permanent and may be more noticeable if you use
Xalacom in only one eye. There appears to be no problems
associated with the change in eye colour. The eye colour change
does not continue after Xalacom treatment is stopped.
