1) What Combigan is and what it is used for
Combigan is an eye drop that is used to control glaucoma. It contains two
different medicines (brimonidine and timolol) that both reduce high pressure
in the eye. Brimonidine belongs to a group of medicines called alpha-2
adrenergic receptor agonists. Timolol belongs to a group of medicines
called beta-blockers. Combigan is prescribed to reduce high pressure in the
eye when beta-blocker eye drops used alone are not enough.
Your eye contains a clear, watery liquid that feeds the inside of the eye.
Liquid is constantly being drained out of the eye and new liquid is made to
replace this. If the liquid cannot drain out quickly enough, the pressure
inside the eye builds up and could eventually damage your sight. Combigan
works by reducing the production of liquid and increasing the amount of
liquid that is drained. This reduces the pressure inside the eye whilst still
continuing to feed the eye.

2) What you need to know before you use Combigan

face, lips and throat, wheeziness, feeling faint, shortness of breath, itching
or redness around the eye

is particularly important to tell your doctor if you are taking:
• pain killers

• medicines for heart conditions (for example an abnormal heartbeat) such
as beta blockers, digoxin or quinidine (used to treat heart conditions and
some types of malaria)

• another eye drop used to lower high pressure in the eye (glaucoma)

• medicines to treat severe allergic reactions

Important information about some of the ingredients of Combigan
Contact Lenses
• Do not use Combigan while your contact lenses are in your eyes. Wait at
least 15 minutes after using Combigan before putting your lenses back in.
• A preservative in Combigan (benzalkonium chloride) may cause eye
irritation and is also known to discolour soft contact lenses.

3) How to use Combigan
Always use Combigan exactly as your doctor has told you. You should
check with your doctor or pharmacist if you are not sure. Combigan must
not be used in infants below 2 years of age. Combigan should not usually
be used in children and adolescents (from 2 to 17 years).
The recommended dose is one drop of Combigan, twice a day about 12
hours apart. Do not change the dose or stop taking it without speaking to
your doctor.
If you have other eye drops as well as Combigan, leave at least 5 minutes
between using Combigan and the other eye drops.
Instructions for use
You must not use the bottle if the tamper-proof seal on the bottle neck is
broken before you first begin to use it.
Wash your hands before opening the bottle. Tilt your head back and look at
the ceiling.

1. Gently pull down the lower eyelid until there is a small pocket.
2. Turn the bottle upside down and squeeze it to release one drop into
each eye that needs treatment.
3. Let go of the lower lid, and close your eye.
4. Keep the eye closed and press your finger against the corner of your
eye (the side where your eye meets your nose) for two minutes. This
helps stop Combigan getting into the rest of the body.
If a drop misses your eye, try again.
To avoid contamination, do not let the tip of the bottle touch your eye or
anything else. Put the screw-cap back on to close the bottle, straight after
you have used it.
If you use more Combigan than you should
If you use more Combigan than you should, it is unlikely to cause you any
harm. Put your next drop in at the usual time. If you are worried, talk to your
doctor or pharmacist.
Babies and Children
Several cases of overdose have been reported in babies and children
receiving brimonidine (one of the ingredients of Combigan) as part of
medical treatment for glaucoma. Signs include sleepiness, floppiness, low
body temperature, paleness and breathing difficulties. Should this happen,
contact your doctor immediately.
Adults and Children
If Combigan has been accidentally swallowed then you should contact your
doctor immediately.
If you forget to use Combigan
If you forget to use Combigan, use a single drop in each eye that needs
treatment as soon as you remember, and then go back to your regular
routine. Do not take a double dose to make up for a forgotten dose.
If you stop using Combigan
Combigan should be used every day to work properly.

Some of these effects may be due to an allergy to any of the ingredients.
Additional side effects have been seen with brimonidine or timolol and
therefore may potentially occur with Combigan.

Leaflet date: 23.03.2016

The following additional side effects have been seen with brimonidine:
- Inflammation within eye, small pupils, difficulty sleeping cold-like
symptoms shortness of breath, symptoms involving the stomach and
digestion, general allergic reactions, skin reactions including redness,
face swelling itching rash and widening of blood vessels
Like other medicines applied into eyes, Combigan (brimonidine/timolol) is
absorbed into the blood. Absorption of timolol, a beta blocker component of
Combigan, may cause similar side effects as seen with intravenous” and /or
“oral” beta-blocking agents. Incidence of side effects after topical
ophthalmic administration is lower than when medicines are for example,
taken by mouth or injected. Listed side effects include reactions seen within
the class of beta-blockers when used for treating eye conditions:
- Generalised allergic reactions, including swelling beneath the skin (that
can occur in areas such as the face and limbs, and can obstruct the
airway which may cause difficulty swallowing or breathing), hives (or
itchy rash), localised and generalised rash, itchiness, severe sudden life
threatening allergic reaction
- Low-blood glucose levels
- Difficulty in sleeping (insomnia), nightmares, memory loss
- Stroke, reduced blood supply to the brain, increased signs and
symptoms of myasthenia gravis (muscle disorder), unusual sensations
(like pins and needles).
- Inflammation in the cornea, detachment of the layer below the retina
that contains blood vessels following filtration surgery which may cause
visual disturbances, decreased corneal sensitivity, corneal erosion
(damage to the front layer of the eyeball), drooping of the upper eyelid
(making the eye half closed), double vision
