What COSOPT-Preservative Free is used for
COSOPT-Preservative Free is used to lower raised pressure in the eye and to treat glaucoma for patients who might be sensitive to preservative-containing formulations or for whom the use of a preservative free formulation is otherwise advisable.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.Also, some people with raised eye pressure may not have glaucoma.
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.The only way of knowing that you have glaucoma is to have your eye pressure, optic nerve and visual field checked by an eye specialist or optometrist.If glaucoma is not treated it can lead to serious problems.You may have no symptoms but eventually glaucoma can lead to total blindness. In fact, untreated glaucoma is one of the most common causes of blindness.
Although COSOPT-Preservative Free helps control your glaucoma it does not cure it.
For more information about glaucoma, contact Glaucoma Australia (PO Box 420, Crows Nest 1585, telephone 1800 500 880).
COSOPT-Preservative Free contains two active ingredients, dorzolamide hydrochloride and timolol maleate.Both of these active ingredients lower pressure in the eye by reducing the production of fluid, but they do this in different ways.
Dorzolamide hydrochloride belongs to a family of medicines called carbonic anhydrase inhibitors.Timolol maleate belongs to a family of medicines called beta-blockers.
COSOPT-Preservative Free is not addictive.

How to use COSOPT-Preservative Free
How much to use
Your doctor will tell you how many drops you need to use each day.
Use COSOPT-Preservative Free only when prescribed by your doctor.
The usual dose for adults is one drop of COSOPT-Preservative Free twice a day, in either one or both eyes.
Follow all directions given to you by your doctor carefully.
They may differ from the information contained in this leaflet.
Use COSOPT-Preservative Free 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.
After using COSOPT-Preservative Free, wait at least 10 minutes before putting any other eye drops in your eye(s).
How to use it
You may find it easier to put drops in your eye while you are sitting or lying down.
The solution from one individual unit dose pipette of COSOPT-Preservative Free is to be used immediately after opening.Since sterility cannot be maintained after the individual unit dose pipette is opened, any remaining contents must be discarded immediately after administration.
If you are wearing soft contact lenses, remove them before putting the drops in your eye.
Wash your hands well with soap and water.
Open the foil pouch which contains 15 individual unit dose pipettes.There are three strips of 5 pipettes each in the pouch.
Break off one pipette from the strip and twist open the top of the pipette.
Hold the pipette upside down in one hand, with your thumb or index finger over the “finger push” area.
Using your other hand, gently pull down your lower eyelid to form a pouch.
Tilt your head back and look up.
Put the tip of the pipette close to your lower eyelid.Do not let it touch your eye.
Release one drop into the pouch formed between your eye and eyelid by gently squeezing the pipette.
Close your eye and keep it closed.Do not blink or rub your eye.
While your eye is still 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.
If you are using COSOPT-Preservative Free in both eyes, repeat this procedure for your other eye.
Discard the pipette, even if there is some solution remaining.
Store the remaining unopened pipettes in the foil pouch; the remaining pipettes must be used within 15 days.
Wash your hands again with soap and water to remove any residue.
You may feel a slight burning sensation in the eye after using the eye drops.
If this persists, or is very uncomfortable, contact your doctor or pharmacist.
How long to use it
COSOPT-Preservative Free helps control your condition but does not cure it. Therefore COSOPT-Preservative Free must be used every day.Continue using COSOPT-Preservative Free for as long as your doctor prescribes.
If you forget to use it
If it is almost time for your next dose, skip the dose you missed and have your next dose when you are meant to.Otherwise, use the drops as soon as you remember, and then go back to using them as you would normally.
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 have trouble remembering to use your eye drops, ask your pharmacist for some hints.
If you use too much (overdose)
If you think that you or anyone else may have swallowed any or all of the contents of a pipette of COSOPT-Preservative Free, or used too many drops, immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to accident or emergency at your nearest hospital.Do this even if there are no signs of discomfort or poisoning.
If COSOPT-Preservative Free 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.
