What Xalacom is and what it is used

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 adequately.

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 long-standing cough)
• if you have serious heart problems or heart rhythm
• if you are pregnant (or trying to become pregnant)
• if you are breast-feeding
Warnings and precautions
Talk to your doctor or pharmacist before using
Xalacom if you have now or have had in the past:
• coronary heart disease (symptoms can include
chest pain or tightness, breathlessness or
choking), heart failure, low blood pressure
• disturbances of heart rate such as slow heart beat
• breathing problems, asthma or chronic obstructive
pulmonary disease
• poor blood circulation disease (such as Raynaud’s
disease or Raynaud’s syndrome)
• diabetes as timolol may mask signs and symptoms
of low blood sugar
• overactivity of the thyroid gland as timolol may
mask signs and symptoms
• 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
• you wear contact lenses. You can still use
Xalacom but follow the 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
• you have suffered or are currently suffering from a
viral infection of the eye caused by the herpes
simplex virus (HSV)
Tell your doctor before you have an operation that
you are using Xalacom as timolol may change
effects of some medicines used during anaesthesia.

In particular, speak to your doctor or pharmacist if
you know that you are taking any of the following
types of medicine:
• Prostaglandins, prostaglandin analogues or
prostaglandin derivates
• Beta-blockers
• Epinephrine
• Drugs used to treat high blood pressure such
as oral calcium channel blockers,

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.

the effects are serious. If you're worried, talk to a
doctor or pharmacist. Do not stop using Xalacom

increasing the amount of brown pigment in the
coloured part of the eye known as the iris. If you
have mixed-colour eyes (blue-brown, grey-brown,
yellow-brown or green-brown) you are more likely
to see this change than if you 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.
Common (may affect up to 1 in 10 people):

Like other medicines applied into eyes, Xalacom is
absorbed into the blood. The timolol portion of this
combination may cause similar side effects as seen
with intravenous and/or oral beta-blocking agents.
Incidence of side effects after topical ophthalmic
application is lower than when medicines are, for
example, taken by mouth or injected. Listed side
effects include reactions seen within the class of
beta-blockers when used for treating eye conditions:
• Generalized allergic reactions including swelling
beneath the skin that can occur in areas such as
the face and limbs and can obstruct the airway
which may cause difficulty swallowing or
breathing, hives or itchy rash, localized and
generalized rash, itchiness, severe sudden
life-threatening allergic reaction.
• Low blood glucose levels.
• Difficulty sleeping (insomnia), depression,
nightmares, memory loss.
• Fainting, stroke, reduced blood supply to the brain,
increases in signs and symptoms of myasthenia
gravis (muscle disorder), dizziness, unusual
sensations like pins and needles, and headache.
• Signs and symptoms of eye irritation (e.g. burning,
stinging, itching, tearing, redness), inflammation of
the eyelid, inflammation in the cornea, blurred
vision and detachment of the layer below the
retina that contains blood vessels following
filtration surgery which may cause visual
disturbances, decreased corneal sensitivity, dry
eyes, corneal erosion (damage to the front layer of
the eyeball), drooping of the upper eyelid (making
the eye stay half closed), double vision.
• Slow heart rate, chest pain, palpitations, oedema
(fluid build up), changes in the rhythm or speed of
the heartbeat, congestive heart failure (heart
disease with shortness of breath and swelling of
the feet and legs due to fluid build up), a type of
heart rhythm disorder, heart attack, heart failure.
