What this medicine is used for

The name of your medicine is Chemmart Latanoprost. It contains the active ingredient latanoprost.
It is used to:
lower raised pressure in the eye
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.
Latanoprost 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 this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that this medicine is addictive.

Use in children

Latanoprost is not recommended for use in children. The safety and effectiveness of latanoprost in children have not been established.

3. You are currently pregnant or you plan to become pregnant. Do not use this medicine whilst pregnant until you and your doctor have discussed the risks and benefits involved.

Taking other medicines

Some medicines may interact with latanoprost. These include:
eye drops which contain an ingredient called thiomersal. If using such eye drops as well as latanoprost, you should wait at least 5 minutes between using these eye drops and latanoprost.
some other eye drops that contain a prostaglandin. The use of two or more prostaglandin eye drops at the same time is not recommended.
If you are using any of these you may need a different dose or you may need to take different medicines.
Other medicines not listed above may also interact with latanoprost.

How to use this medicine

Use latanoprost only when prescribed by your doctor.
Follow carefully all directions given to you by your doctor.
Their instructions may be different to the information 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 latanoprost is one drop into the affected eye, or eyes, once daily.
Use latanoprost every day, at about the same time each day, preferably in the evening, unless your doctor tells you otherwise.

How to use it

The preservative in latanoprost (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 latanoprost.
If using other eye drops in addition to latanoprost, wait at least 5 minutes before putting any other drops in your eye(s).
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.

1. Wash your hands well with soap and water.

2. Unscrew the cap and break off from seal.

3. Use your finger to gently pull down the lower eyelid of your affected eye.

4. Tilt your head back and look up.

5. Place the tip of the bottle close to but not touching your eye.

6. 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.

7. 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.

8. Screw the cap back on the bottle.

9. Wash your hands again with soap and water to remove any residue.

If this persists, or is very uncomfortable, contact your doctor.

When to use it

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 long to use it for

Continue using latanoprost every day for as long as your doctor prescribes.
Latanoprost helps control your condition but does not cure it.

If you forget to use it

If it is almost time to put your next dose, skip the missed dose and use your next dose at the usual time. Otherwise put it as soon as you remember and then go back to taking your medicine as you would normally.
If you are not sure whether to skip the dose, talk to your doctor.
Do not double dose to make up for missed doses.
This may increase the chance of you experiencing side effects.
If you have trouble remembering to use your medicine, ask your pharmacist for some hints to help you remember.

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 latanoprost, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency department at your nearest hospital.
