What ENIDIN® eye drops are used for
ENIDIN® eye drops are 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. 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, including total blindness. In fact, untreated glaucoma is one of the most
common causes of blindness.
Although ENIDIN® eye drops help control your glaucoma, it does not cure it.
For more information about glaucoma, contact the Glaucoma Australia Inc. (telephone
1800 500 880).
ENIDIN® eye drops are used, either alone or in combination with other eye drops/medicines,
to lower raised pressure within your eye(s).
Mechanism of action:
ENIDIN® eye drops lower the pressure in the eye by decreasing the fluid produced and helping
the flow of fluid out of the eye chamber.
Your doctor may have prescribed ENIDIN® eye drops for another reason. Ask your doctor if you have any questions about why
ENIDIN® eye drops have been prescribed for you.

How to use ENIDIN® eye drops
How much to use
The usual dosage of eye drops is one drop in the eye(s) every twelve hours. If you
are using more than one eye drop product, wait 5 to 10 minutes before using the second
product so that the first eye drop is not washed out by, or interacts with the second.
Your doctor will tell you how many drops you need to use each day. Use ENIDIN® eye drops 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.
Use ENIDIN® eye drops 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.
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 to use it
You may find it easier to put drops in your eye while you are sitting or lying down.
If you are wearing soft contact lenses, remove them before putting the drops in your
eye.
To open a new bottle of ENIDIN® eye drops, first tear off the protective seal from the bottle. The seal will break
and you can pull it off and then throw it away.
1. Wash your hands well with soap and water.
2. Shake the bottle gently.
4. Hold the bottle upside down in one hand between your thumb and forefinger or index
finger.
5. Using your other hand, gently pull down your lower eyelid to form a pouch or pocket.
6. Tilt your head back and look up.
7. Put the tip of the bottle close to your lower eyelid. Do not let the tip touch your
eye.
8. Release one drop into the pouch or pocket formed between your eye and eyelid by gently
squeezing the bottle.
9. Close your eye. Do not blink or rub your eye.
10. 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.
11. Replace the cap, sealing it tightly.
12. Wash your hands again with soap and water to remove any residue.
Wait 15 minutes before replacing your contact lenses.
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.
Be careful not to touch the dropper tip against your eye, eyelid or anything else
to avoid contaminating the eye drops.
Contaminated eye drops may give you an eye infection.
How long to use it
ENIDIN® eye drops help control your condition but does not cure it. Therefore ENIDIN® eye drops must be used every day. Continue using ENIDIN® eye drops for as long as your doctor prescribes.
For some people ENIDIN® eye drops may have been prescribed for a short time before or after eye surgery.
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 the drops as soon as you remember, and
then go back to using/taking 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 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 any or all of the contents
of a bottle of ENIDIN® eye drops, immediately telephone your doctor or Poisons Information Centre (telephone
13 11 26) for advice, or go to casualty at your nearest hospital.
Do this even if there are no signs of discomfort or poisoning.
