What Nyogel is used for
This medicine is used to lower the pressure in the eye and to prevent loss of vision in glaucoma.
It works by decreasing the formation of fluid which flows through the eye.
The eye is filled with fluid which is constantly being replaced. If excessive amounts of fluid are produced or if it cannot drain away properly, the pressure inside the eye can damage the nerve cells that transmit information from the eye to the brain. This nerve cell damage is called glaucoma.
Glaucoma is often but not always associated with increased pressure in the eye. A reduction of the pressure inside the eye can prevent further nerve cell damage.
There are usually no symptoms of glaucoma. Damage can progress so slowly that you are not aware of a gradual loss of sight. The only way of knowing 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.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is not addictive.
It is available only with a doctor's prescription.
There is not enough information to recommend the use of this medicine for children under the age of 12 years.

- an overactive thyroid
- any other type of glaucoma than that for which you have been given this medicine
Tell your doctor if you are pregnant or plan to become pregnant. Your doctor can discuss with you the risks and benefits involved.
Tell your doctor if you wear soft contact lenses. The preservative in Nyogel (benzalkonium chloride) is known to discolour soft contact lenses. You should not wear soft contact lenses while using this medicine. You can put your contact lenses into your eyes 15 minutes after you have used Nyogel.
If you have not told your doctor about any of the above, tell him/her before you start using Nyogel.
Taking other medicines
Tell your doctor or pharmacist if you are taking or using any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.
Some medicines and Nyogel may interfere with each other. These include:
- medicines used to treat high blood pressure including a group of medicines called beta-blockers that are also used to treat heart problems and to prevent migraine
- other medicines used to treat glaucoma
- medicines used to treat heart disease or abnormal heart beat
- medicines used to treat depression or schizophrenia
- cimetidine used to treat stomach ulcers.
These medicines may be affected by Nyogel or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while using this medicine.
How to use Nyogel
Follow the directions given to you by your doctor or pharmacist carefully. These directions may differ from the information contained in this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
How much to use
The usual dose is one drop in the affected eye(s) daily.
How to use it
To use this medicine:
- First wash your hands and sit or stand comfortably.
- With your head tilted back, use your forefinger to gently pull down the lower lid of the eye to be treated.
- Hold the container upside down above your eye and place the dropper tip close to your eye but without touching the eye or lid.
- Squeeze the bottle gently so that only one drops falls into the pouch between your lower lid and your eye, then release your lower lid.
To ensure you get the correct dose, keep the bottle vertical while putting in the drops.
- Close your eyelid and gently press the inner corner of your eye for one minute.
- Treat your other eye in the same way if your doctor has told you to do this.
- Put the cap back on the bottle. Discard the bottle and remaining gel four weeks after opening.
If you are using any other eye drops at the same time as Nyogel, leave an interval of at least 5 minutes between each eye drop to stop the drops being washed out of the eye. Use Nyogel last.
When to use it
Use your medicine at about the same time each day, preferably in the morning. Using it at the same time each day will have the best effect. It will also help you remember when to use it.
How long to use it
Continue using your medicine for as long as your doctor tells you. This medicine helps to control your condition, but does not cure it. It is important to keep using your medicine even if you feel well.
If you forget to use it
If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to.
Otherwise, use it as soon as you remember, and then go back to using your medicine as you would normally.
Do not use a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to use your medicine, ask your pharmacist for some hints.
If you use too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26 in Australia or 0800 764 766 in New Zealand) if you think that you or anyone else may have used too much Nyogel. Do this even if there are no signs of discomfort or poisoning. You may need medical attention.
While you are using Nyogel
Things you must do
If you wear soft contact lenses, stop wearing them while you are using Nyogel.
If you are going to have surgery, tell the surgeon or anesthetist that you are using this medicine. You may be advised to gradually stop using Nyogel prior to surgery.
If you have diabetes, you should monitor your blood sugar carefully, particularly when starting Nyogel. Nyogel may mask the symptoms of low blood sugar.
If you are having an x-ray that requires you to have an injection of dye containing iodine, tell the person doing the x-ray that you are using Nyogel. Nyogel and x-ray injections that contain iodine may interfere with one another.
If you become pregnant while using this medicine, tell your doctor immediately.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are using Nyogel.
Tell any other doctors, dentists and pharmacists who treat you that you are using this medicine.
Keep all of your doctor's appointments so that your progress can be checked.
Things you must not do
Do not use Nyogel to treat any other complaints unless your doctor tells you.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop using your medicine or lower the dosage without checking with your doctor.
Things to be careful of
Be careful driving or operating machinery until you know how Nyogel affects you. This medicine may cause visual disturbances and dizziness or fatigue in some people. If you get these symptoms when you use it, do not drive, operate machinery or do anything else that could be dangerous until this effect has worn off.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using Nyogel. This medicine helps most people with increased pressure in the eye, but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

The above list includes serious side effects which may require medical attention. Serious side effects are rare.
Tell your doctor if you notice anything else that is making you feel unwell. Other side effects not listed above may also occur in some people.
After using Nyogel
Keep your eye gel in a cool dry place where the temperature stays below 25°C.
After opening, use the bottle of eye gel for four weeks and then get a new bottle of eye gel, even if there is some left in the old bottle.
Store the dropper bottle upside down in the carton to facilitate instillation of the eye gel.
Do not store Nyogel or any other medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.
Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
If your doctor tells you to stop using this medicine or the expiry date has passed, ask your pharmacist what to do with any medicine that is left over.
