1. What ALPHAGAN is and what it is used for

ALPHAGAN is used to reduce pressure within the eye. The active ingredient in ALPHAGAN is brimonidine tartrate which belongs to a group of medicines called alpha-2 adrenergic receptor agonists and works by reducing pressure within the eyeball.

It can be used either alone, when beta-blocker eye drops are contraindicated, or with another eye drop, when a single medicine is not enough to lower the increased pressure in the eye, in the treatment of open angle glaucoma or ocular hypertension.

2. What you need to know before you use ALPHAGAN
Do not use ALPHAGAN
  • If you are allergic (hypersensitive) to brimonidine tartrate or any of the other ingredients of this medicine (listed in section 6).
  • If you are taking monoamine oxidase (MAO) inhibitors or certain other antidepressants. You must inform your doctor if you are taking any antidepressant drug.
  • If you are breast-feeding.
  • In infants/babies (from birth until 2 years).

Warnings and precautions

Talk to your doctor before using ALPHAGAN

  • If you suffer or have suffered from depression, reduced mental capacity, reduced blood supply to the brain, heart problems, a disturbed blood supply of the limbs or a blood pressure disorder.
  • If you have or have had in the past kidney or liver problems.

Children and Adolescents

ALPHAGAN is not recommended for use in children between the ages of 2 and 12 years.

ALPHAGAN should not usually be used in adolescents aged 12 to 17 as clinical studies have not been performed in this age group.

Other medicines and ALPHAGAN

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Tell your doctor if you are taking any of the following medicines:

  • pain killers, sedatives, opiates, barbiturates or are regularly consuming alcohol.
  • anaesthetics.
  • to treat a heart condition or to lower blood pressure.
  • that can affect the metabolism like chlorpromazine, methylphenidate and reserpine.
  • which work on the same receptor as ALPHAGAN, for example isoprenaline and prazosin.
  • monoamine oxidase (MAO) inhibitors and other antidepressants.
  • medicines for any condition, even if unrelated to your eye condition.
  • or if the dose of any of your current medicines is changed.

These could affect your treatment with ALPHAGAN.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Do not use ALPHAGAN if you are pregnant unless your doctor considers it necessary.

ALPHAGAN should not be used while breast-feeding.

Driving and using machines

ALPHAGAN may cause blurred or abnormal vision. This effect may seem worse at night or in reduced lighting.

ALPHAGAN may also cause drowsiness or tiredness in some patients.

If you experience any of these symptoms, do not drive or use machinery until the symptoms are cleared.

ALPHAGAN contains Benzalkonium chloride

ALPHAGAN contains 0.25 mg benzalkonium chloride in each 5 ml of solution which is equivalent to 0.05 mg/ml.

Benzalkonium chloride is a preservative which may be absorbed by soft contact lenses and may change the colour of the contact lenses. You should remove contact lenses before using this medicine and put them back 15 minutes afterwards.

Benzalkonium chloride may also cause eye irritation, especially if you have dry eyes or disorders of the cornea (the clear layer at the front of the eye). If you feel abnormal eye sensation, stinging or pain in the eye after using this medicine, talk to your doctor.

3. How to use ALPHAGAN

Always use ALPHAGAN exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.


The recommended dose is one drop twice daily in the affected eye(s), approximately 12 hours apart. Do not change the dose or stop taking ALPHAGAN without speaking to your doctor.

Children under 12 years

ALPHAGAN must not be used for infants below 2 years of age.

ALPHAGAN is not recommended for use in children (from 2 years until 12 years).

Instructions for use

ALPHAGAN comes as eye drops. Always wash your hands before applying eye drops. Your prescription label tells you how many drops to use at each dose. If you use ALPHAGAN with another eye drop, wait 5-15 minutes before applying the second eye drop.

Apply your eye drops in the following way:

1. Tilt your head back and look at the ceiling.
2. Gently pull the lower eyelid down until there is a small pocket.
3. Squeeze the upturned dropper bottle to release a drop into your eye.
4. Whilst keeping the affected eye closed, press your finger against the corner of the closed eye (the side where the eye meets the nose) and hold for 1 minute.

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. Replace and tighten the cap straight after use.

If you use more ALPHAGAN than you should


In adults who were instilling more drops than prescribed, the side effects reported were those already known to occur with ALPHAGAN.

Adults who accidentally swallowed ALPHAGAN experienced decrease in blood pressure, which in some patients was followed by the increase in blood pressure.


Serious side effects were reported in children who accidentally swallowed ALPHAGAN. Signs included sleepiness, floppiness, low body temperature, paleness and breathing difficulties. Should this happen, contact your doctor immediately.

Adults and Children

If ALPHAGAN has been accidentally swallowed or if you have used more ALPHAGAN than you should, please contact your doctor immediately.

If you forget to use ALPHAGAN

If you forget to take a dose, apply it as soon as you remember. If, however, it is almost time for your next dose, you should omit the missed dose altogether and then follow your normal routine.

If you stop using ALPHAGAN

To be effective ALPHAGAN must be used every day. Do not stop using ALPHAGAN until your doctor tells you to.

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