What ALPHAGAN® P 1.5 eye drops are used for

ALPHAGAN® P 1.5 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.

Eye 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.

ALPHAGAN® P 1.5 eye drops lower the pressure in the eye by decreasing the fluid produced and helping the flow of fluid out of the eye chamber.

Although ALPHAGAN® P 1.5 eye drops help control your glaucoma, it does not cure it.

ALPHAGAN® P 1.5 eye drops are used, either alone or together with other eye drops/medicines, to lower raised pressure within your eye(s).

ALPHAGAN® P 1.5 eye drops are only available with a doctor’s prescription from pharmacies.

Your doctor may have prescribed ALPHAGAN® P 1.5 eye drops for you instead of ALPHAGAN® eye drops. The main difference between ALPHAGAN® P 1.5 and ALPHAGAN® is the preservative; ALPHAGAN® P 1.5 contains ‘Purite’ (hence the ‘P’) whereas ALPHAGAN® contains benzalkonium chloride (see Product Description).

ALPHAGAN® P 1.5 belongs to a family of medicines called alpha-adrenergic agonists.

Your doctor may have prescribed ALPHAGAN® P 1.5 eye drops for another reason. Ask your doctor if you have any questions about why ALPHAGAN® P 1.5 eye drops have been prescribed for you.

How to use ALPHAGAN® P 1.5 eye drops

How much to use

Your doctor will tell you how many drops you need to use each day. Use ALPHAGAN® P 1.5 eye drops only when prescribed by your doctor.

The usual dosage of eye drops is one drop in the eye(s) every twelve hours.

Follow all directions given to you by your doctor carefully. The directions may differ from the information contained in this leaflet.

Use ALPHAGAN® P 1.5 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.

After using ALPHAGAN® P 1.5, wait at least 5 - 10 minutes before putting any other eye drops in your eye.

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.

To open a new bottle of ALPHAGAN® P 1.5 eye drops, first tear off the protective seal from the bottle. The contents are sterile if seal is intact. 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.
  3. Remove the cap.
  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.

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.

ALPHAGAN® P 1.5 eye drops are for use in eyes only.

How long to use it

ALPHAGAN® P 1.5 eye drops help control your condition but do not cure it. Therefore ALPHAGAN® P 1.5 eye drops must be used every day. Continue using ALPHAGAN®P 1.5 eye drops for as long as your doctor prescribes.

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 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 ALPHAGAN® P 1.5 eye drops, immediately telephone your doctor or Poisons Information Centre (New Zealand Freephone 0800 764 766) for advice, or go to Accident and Emergency at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning.

After using ALPHAGAN® P 1.5 eye drops


Keep your eye drops in a cool place where the temperature stays below 25°C.

Do not store it or any other medicine in the bathroom or near a sink. Do not leave it in the car or on window sills. Do not carry the eye drops in pockets of your clothes. Heat and dampness can destroy some medicines.

Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres (5 feet) above the ground is a good place to store medicines.

Do not leave the lid off the bottle for any length of time to avoid contaminating the eye drops.


Write the date on the bottle when you open the eye drops and throw out any remaining solution after four weeks.

Eye drops contain a preservative which helps prevent germs growing in the solution for the first four weeks after opening the bottle. After this time there is a greater risk that the drops may become contaminated and cause an eye infection. A new bottle should be opened.

If your doctor tells you to stop using the eye drops or they have passed their expiry date, ask your pharmacist what to do with any remaining solution.
