What Xalaprost is used for
Xalaprost 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.
Xalaprost belongs to a family of medicines called prostaglandin agonists.
It lowers the pressure in the eye by allowing more fluid to flow out from within your eye.
Although Xalaprost helps control your glaucoma it does not cure it. So you must keep using it until your doctor tells you to stop.
Xalaprost is used, either alone or in combination with other eye medicines, to lower raised pressure within your eye.
Ask your doctor if you have any questions about why Xalaprost has been prescribed for you. Your doctor may have prescribed it for another reason.
Xalaprost is not addictive.
Xalaprost is not recommended for use in children. The safety and effectiveness of Xalaprost in children have not been established.
Before you use Xalaprost
When you must not use it
Do not use Xalaprost if:
- you have an allergy to Xalaprost 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
– swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing
– hives, itching or skin rash
- the bottle or packaging shows signs of tampering
- the expiry date on the pack has passed.
If you use this medicine after the expiry date has passed, it may not work.
If you are not sure whether you should start using Xalaprost, talk to your doctor.
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
Your doctor will discuss the possible risks and benefits of using Xalaprost during pregnancy.
- you are breast-feeding or intend to breast-feed
Your doctor will discuss the possible risks and benefits of using Xalaprost when breast-feeding.
- you have or have had any medical conditions such as severe asthma, or any other types of glaucoma or eye conditions.
If you have not told your doctor about any of the above, tell him or her before you use Xalaprost.
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 Xalaprost may interfere with each other. These include:
- eye drops which contain an ingredient called thiomersal. If using such eye drops as well as Xalaprost, you should wait at least 5 minutes between using these eye drops and Xalaprost
- some other eye drops that contain a prostaglandin. The use of two or more prostaglandin eye drops at the same time is not recommended.
How to use Xalaprost
Use Xalaprost 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 Xalaprost is one drop into the affected eye, or eyes, once daily.
Use Xalaprost every day, at about the same time each day, preferably in the evening, 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 Xalaprost (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 Xalaprost.
If using other eye drops in addition to Xalaprost, 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 Xalaprost every day for as long as your doctor prescribes. Xalaprost 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, immediately rinse your eye with warm water.
If you think that you or anyone else may have swallowed Xalaprost, immediately telephone your doctor or the Australian Poisons Information Centre (telephone 13 11 26) or go to Accident and Emergency at your nearest hospital. Do this even if there are no signs of discomfort or poisoning.
While you are using Xalaprost
Things you must do
To make sure Xalaprost 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 Xalaprost. Your doctor will decide whether you should continue using Xalaprost.
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 Xalaprost because of possible contamination of the old one, or may advise you to stop your treatment with Xalaprost.
If you become pregnant while using Xalaprost, tell your doctor immediately.
If you are about to be started on any new medicine tell your doctor and pharmacist that you are using Xalaprost.
Tell all doctors and pharmacists who are treating you that you are using Xalaprost.
Things you must not do
Do not give Xalaprost to anyone else, even if they have the same condition as you.
Do not use this medicine to treat any other complaints unless your doctor tells you to.
Do not stop using Xalaprost without first talking to your doctor. If you stop using 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 Xalaprost affects you. Xalaprost 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 Xalaprost or that your vision is clear before driving a car or operating machinery.
Check with your doctor as soon as possible if you have any problems while using Xalaprost, even if you do not think the problems are connected with the medicine or are not listed in this leaflet. Like other medicines, Xalaprost can cause some side effects. If they occur, most are likely to be minor and temporary. However, some may be serious and need medical attention.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
- a slow change in eye colour over a period of time. The iris may become browner in colour and appear darker. This change may be permanent and more noticeable if you are only being treated in one eye
- blurred vision, double vision or other visual problems
- irritation or feeling of having something in the eye. This may be worse during the first two or three days of using Xalaprost
- eye pain
- redness, burning or watering of the eye(s)
- discharge, itching of the eye(s), crusty eyelashes
- darkening, thickening, lengthening or an increase in the number of eye lashes and the fine hair on the eyelids
- misdirected eyelashes sometimes causing eye irritation
- darkening of the skin of the eyelids
- crusting, redness, thickening, itching or burning of the eyelids
- sensitivity to light
- skin rash
- muscle/joint pain
- painful, urgent or frequent urination.
If any of the following happen, stop using Xalaprost and tell your doctor immediately or go to Accident and Emergency at your nearest hospital:
- wheezing, difficulty in breathing (asthma or worsening of asthma)
- shortness of breath
- chest pain
- swelling of the face, lips, mouth, tongue or throat which may cause difficulty in swallowing or breathing
- white deposits or plaque in the cornea causing the transparent front part of your eye to look white or cloudy.
These are rare but serious side effects. You may need urgent medical attention.
Tell your doctor if you notice any other effects. Other side effects not listed above may also occur in some patients.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
After using Xalaprost
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 Xalaprost, keep the bottle in its box in a refrigerator (2°C – 8°C) protected from light.
After opening Xalaprost, 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 Xalaprost 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
Xalaprost 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 Xalaprost 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 ingredient in Xalaprost eye drops is latanoprost. Each 1 mL of Xalaprost contains 50 micrograms of latanoprost. Each drop contains about 1.5 micrograms of latanoprost.
Xalaprost eye drops also contain:
- sodium chloride
- sodium phosphate monobasic monohydrate
- sodium phosphate dibasic anhydrous
- water for injections
- benzalkonium chloride (as a preservative).
Xalaprost can be identified by the Australian Register Number AUST R 217151, which is found on the box.
