6. Contents of the pack and other information
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
Do not use Combigan eye drops solution:
if you are allergic (hypersensitive) to brimonidine tartrate, timolol, beta-blockers or
any of the other ingredients of this medicine (listed in section 6). Symptoms of an
allergic reaction may include swelling of the face, lips and throat, wheeziness, feeling
faint, shortness of breath, itching or redness around the eye.
if you have now or have had in the past respiratory problems such as asthma, severe
chronic obstructive bronchitis (severe lung disease which may cause wheeziness,
difficulty in breathing and/or long-standing cough).
if you have heart problems such as low heart rate, heart failure, heart beat
disorders (unless controlled by a pacemaker).
if you are taking monoamine oxidase (MAO) inhibitors or certain other
antidepressant drugs.
Combigan should not be used in children less than 2 years old and should not usually be
used in children aged 2 to 17.
If you think any of these points apply to you, do not use Combigan until you have talked
again to your doctor.

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. 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 minute. 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
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.
If you have any further questions on the use of this product, ask your doctor or pharmacist.

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
Like other medicines applied into eyes, Combigan (brimonidine/timolol) is absorbed into the
blood. Absorption of timolol, a beta blocker component of Comgiban, 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
- Chest pain, oedema (fluid build up), changes in the rhythm or speed of the heart beat, a
type of heart rhythm disorder, heart attack, heart failure,
- Raynaud’s phenomenon, cold hands and feet
- Constriction of the airways in the lung (predominantly in patients with pre-existing
disease) difficulty breathing, cough Indigestion, abdominal pain, vomiting
- Hair loss, skin rash with white silvery coloured appearance (psoriasiform rash) or
worsening of psoriasis, skin rash
- Muscle pain not caused by exercise
- Sexual dysfunction, decreased libido
- Muscle weakness/tiredness
Other side effects reported with eye drops containing phosphates:
In very rare cases, some patients with severe damage to the clear layer at the front of the
eye (the cornea) have developed cloudy patches on the cornea due to calcium build up
during treatment.
