What Xalacom is used for
Xalacom is used to lower raised pressure in the eye and to treat glaucoma. Glaucoma is a condition in which the pressure of fluid in the eye may be high. However, some people with glaucoma may have normal eye pressure.
Glaucoma is usually caused by a build up of the fluid which flows through the eye. This build up occurs because the fluid drains out of your eye more slowly than it is being pumped in. Since new fluid continues to enter the eye, joining the fluid already there, the pressure continues to rise. This raised pressure may damage the back of the eye resulting in gradual loss of sight. Damage can progress so slowly that the person is not aware of this gradual loss of sight. Sometimes even normal eye pressure is associated with damage to the back of the eye.
There are usually no symptoms of glaucoma. If glaucoma is not treated it can lead to serious problems, including total blindness. In fact, untreated glaucoma is one of the most common causes of blindness.
Xalacom is made up of 2 active ingredients, latanoprost and timolol maleate. Latanoprost works by allowing more fluid to flow out from within your eye(s). Timolol maleate lowers the pressure in the eye by reducing the production of fluid.
Latanoprost belongs to a family of medicines called prostaglandin agonists. Timolol maleate belongs to a family of medicines called beta-blockers.
Although Xalacom helps control your glaucoma it does not cure it. So you must keep using it until your doctor tells you to stop.
Ask your doctor if you have any questions about why Xalacom has been prescribed for you.
Your doctor may have prescribed it for another reason.
Xalacom is not recommended for use in children. The safety and effectiveness of Xalacom in children have not been established.
Before you use Xalacom

- you have an allergy to Xalacom or any of the ingredients listed at the end of this leaflet
- Symptoms of an allergic reaction may include:
- asthma, wheezing or shortness of breath

Before you start to use it
Tell your doctor if:
- you have had an allergy to any other medicines or any other substances, such as foods, preservatives or dyes
- you are pregnant or intend to become pregnant
There is no adequate experience with Xalacom in pregnant women, therefore, it should not be used during pregnancy.
- you are breast-feeding or intend to breast-feed
One of the active ingredients in Xalacom has been detected in breast milk. Because of the potential harm to the infant, nursing women should either stop using Xalacom or stop breast-feeding while using it.
- you have or have had any medical conditions, especially the following:
- heart disease
- lung disease
- circulation problems
- any other types of glaucoma or eye conditions
- myasthenia gravis
Tell your doctor if you plan to have surgery.
If you have not told your doctor about any of the above, tell him or her before you use Xalacom.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines and Xalacom may interfere with each other. These include:
- certain medicines used to treat high blood pressure or heart conditions such as beta-blockers, calcium channel blockers or digoxin
- certain medicines used to treat irregular heartbeats such as amiodarone and quinidine
- some medicines used to treat depression, such as phenelzine, fluoxetine or paroxetine
- some medicines used to treat Parkinson's disease, such as selegiline
- adrenaline, a hormone used in the treatment of asthma, slow or irregular heartbeat, acute allergic disorders and glaucoma
- some medicines that may have been prescribed to help you pass urine or restore normal bowel movements
- narcotics such as morphine used to treat moderate to severe pain
- eye drops which contain an ingredient called thiomersal. If using such eye drops as well as Xalacom, you should wait at least 5 minutes between using these eye drops and Xalacom
- medicines used to treat diabetes or high blood sugar
- some other eye drops that contain a beta-blocker or a prostaglandin. The use of two or more beta-blocker eye drops and/or two or more prostaglandin eye drops at the same time is not recommended.
Your doctor or pharmacist has more information on medicines to be careful with or avoid while using Xalacom.
How to use Xalacom
Use Xalacom only when prescribed by your doctor.
Follow all directions given to you by your doctor carefully.
They may differ from the information contained in this leaflet.
If you are being changed from one eye drop to another, follow your doctor's instructions carefully as to when to stop the old drops and when to start the new drops.
How much to use
The usual dose of Xalacom is one drop into the affected eye, or eyes, once daily.
Use Xalacom every day, at about the same time each day, unless your doctor tells you otherwise.
Using your eye drops at the same time each day will have the best effect on your eye pressure. It will also help you remember when to use the eye drops.
How to use it
If you are wearing soft contact lenses, remove them before putting the drops in your eye.
The preservative in Xalacom (benzalkonium chloride) may be deposited in soft contact lenses. You can put your soft contact lenses back into your eyes 15 minutes after you have used Xalacom.
If using other eye drops in addition to Xalacom, wait at least 5 minutes before putting any other drops in your eye(s).
Be careful not to touch the dropper tip against your eye, eyelid or anything else.
Touching the dropper tip against something may contaminate the eye drops and give you an eye infection.
You may find it easier to put drops in your eye while you are sitting or lying down.
- Wash your hands well with soap and water.
- Twist off the protective overcap from the bottle.
- Unscrew the inner cap.
- Use your finger to gently pull down the lower eyelid of your affected eye.
- Tilt your head back and look up.
- Place the tip of the bottle close to but not touching your eye. Squeeze the bottle gently so that only one drop goes into your eye, then release the lower eyelid. Close your eye. Do not blink or rub your eye.
- While your eye is closed, place your index finger against the inside corner of your eye and press against your nose for about two minutes. This will help to stop the medicine from draining through the tear duct to the nose and throat, from where it can be absorbed into other parts of your body. Ask your doctor for more specific instructions on this technique.
- Screw the inner cap back on the bottle.
- Wash your hands again with soap and water to remove any residue.
You may feel a slight burning sensation in the eye shortly after using the eye drops.
If this persists, or is very uncomfortable, contact your doctor or pharmacist.
How long to use it
Continue using Xalacom every day for as long as your doctor prescribes.
Xalacom helps control your condition but does not cure it.
If you forget to use it
If you miss a dose, skip the dose you missed and use your next dose when you are meant to.
If you are not sure whether to skip the dose, talk to your doctor or pharmacist.
Do not use double the amount to make up for the dose that you missed.
If you use too much (overdose)
If you accidentally put several drops in your eye(s), immediately rinse your eye(s) with warm water.
If you think that you or anyone else may have swallowed Xalacom, immediately telephone your doctor or the Australian Poisons Information Centre (telephone 13 11 26) or the New Zealand National Poisons Information Centre (telephone 0800 POISON or 0800 764 766) for advice, or go to Accident and Emergency at your nearest hospital. Do this even if there are no signs of discomfort or poisoning.
If Xalacom is accidentally swallowed, or if you use too many drops, you may feel light-headed or dizzy, you may faint, have a very slow pulse rate, or have wheezing or difficulty breathing. Other effects include headache, nausea, abdominal pain, fatigue, hot flushes and sweating.
While you are using Xalacom
Things you must do
To make sure Xalacom is working properly, have your eye pressure checked regularly. Have your eyes checked regularly for any other changes, including a change in eye colour.
A slow change in eye colour, which may be permanent, has been reported to occur in some patients who use Xalacom. Your doctor will decide whether you should continue using Xalacom.
If you develop an eye infection, receive an eye injury, or have eye surgery tell your doctor.
Your doctor may tell you to use a new container of Xalacom because of possible contamination of the old one, or may advise you to stop your treatment with Xalacom.

If you stop using your eye drops, your eye pressures may rise again and damage to your eye may occur.
Things to be careful of
Be careful driving or operating machinery until you know how Xalacom affects you.
Xalacom generally does not cause any problems with your ability to drive a car or operate machinery. However, it may cause blurred vision in some people. Make sure you know how you react to Xalacom or that your vision is clear before driving a car or operating machinery.

After using Xalacom
Keep your eye drops in a safe place away from the sight and reach of children.
A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
Before opening Xalacom, keep the bottle in its box in a refrigerator (2°C - 8°C) protected from light.
After opening Xalacom, keep the bottle in its box in a cool place where the temperature stays below 25°C, but do not refrigerate. Keep the box properly closed and protected from light.
Do not store Xalacom or any other medicine in the bathroom or near a sink. Do not leave it in the car or on window sills. Do not carry the eye drops in pockets of your clothes.
Heat and dampness can destroy some medicines.
Put the top back on the bottle right away after use to avoid contaminating the eye drops.
Write the date on the bottle when you open the eye drops and throw out any remaining solution after four weeks.
Open a new bottle every 4 weeks.
Eye drops contain a preservative which helps prevent germs growing in the solution for the first four weeks after opening the bottle. After this time there is a greater risk that the drops may become contaminated and cause an eye infection.
If your doctor tells you to stop using the eye drops or they have passed their expiry date, ask your pharmacist what to do with any remaining solution.
What it looks like
Xalacom eye drops come in a plastic bottle with a dropper and screw cap inside a protective overcap. Remove this overcap before use.
When you first receive your Xalacom bottle, it will appear half full. This corresponds to 2.5 mL of eye drop solution, giving a minimum of 80 drops. This volume is enough to last 4 weeks if used in both eyes.
The active ingredients in Xalacom eye drops are latanoprost and timolol maleate. Each 1 mL of Xalacom contains 50 micrograms of latanoprost and 5 mg of timolol (equivalent to 6.83 mg timolol maleate). Each drop contains about 1.5 micrograms of latanoprost and 150 micrograms of timolol.
Xalacom eye drops also contain:
- sodium chloride
- sodium phosphate monobasic monohydrate
- sodium phosphate dibasic anhydrous
- Water for Injections
- benzalkonium chloride (as a preservative).
