1. WHAT DORZOLAMIDE EYE DROPS ARE AND WHAT THEY ARE USED FOR

The full name of your medicine is ‘Dorzolamide 20mg/ml Eye drops, solution’ (referred to as Dorzolamide eye drops in the rest of this leaflet).

Dorzolamide eye drops are a sterile eye drop solution. Dorzolamide eye drops contain dorzolamide, a sulphonamide-related compound, as the active ingredient.

Dorzolamide is an ophthalmic carbonic anhydrase inhibitor which reduces high pressure in the eye.

It is prescribed to lower raised pressure in the eye in conditions such as ocular hypertension and glaucoma (open-angle glaucoma, pseudo-exfoliative glaucoma). Dorzolamide eye drops can be used alone or in addition to other medicines which lower the pressure in the eye (so-called beta-blockers).

2. BEFORE YOU USE DORZOLAMIDE EYE DROPS

Do not use Dorzolamide eye drops

-    if you are allergic (hypersensitive) to dorzolamide or any of the other ingredients of this solution.

-    if you have severe kidney problems.

Take special care with Dorzolamide eye drops

Before treatment with Dorzolamide eye drops, tell your doctor

-    if you have or have had liver problems in the past

-    if you have been told you have a problem in the surface layer of the eye

-    if you have had any allergies to any medicines

-    if you have had, or are about to have eye surgery

-    if you have suffered an eye injury or have an eye infection

-    if you have a prior history of kidney stones

-    if you are taking orally another carbonic anhydrase inhibitor such as acetazolamide

-    if you wear contact lenses (see the section ‘Important information about some of the ingredients of Dorzolamide eye drops).

You should contact your doctor immediately if you develop any eye irritation or any new eye problems such as redness of the eye or swelling of the surface layer of the eye or eyelids.

Stop using Dorzolamide eye drops and contact your doctor immediately if you suspect that Dorzolamide eye drops are causing an allergic reaction (for example, skin rash or itching, inflammation of the eye).

Use in children

Dorzolamide eye drops have been studied in infants and children less than 6 years of age who have raised pressure in the eye(s) or have been diagnosed with glaucoma. For more information, talk to your doctor.

Using other medicines

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

In particular you should tell your doctor if you are taking another carbonic anhydrase inhibitor such as acetazolamide. You may be taking this type of medicine by mouth, as eye drops, or by some other method.

Pregnancy and breast-feeding

Ask your doctor or pharmacist for advice before taking any medicine. Tell your doctor if you are pregnant or planning to become pregnant. Dorzolamide eye drops should not be used during pregnancy unless your doctor still recommends it. Dorzolamide eye drops should not be used while breast-feeding.

Driving and using machines

Dorzolamide eye drops may cause dizziness and visual disturbances in some patients. Do not drive or use any tools or machines until the symptoms have cleared.

Important information about some of the ingredients of Dorzolamide eye drops

Dorzolamide eye drops contain the preservative benzalkonium chloride.

•    Benzalkonium chloride may cause eye irritation.

•    Benzalkonium chloride is known to discolour soft contact lenses.

•    Avoid contact with soft contact lenses.

•    Remove contact lenses prior to application and wait until 15 minutes before reinsertion.

3. HOW TO USE DORZOLAMIDE EYE DROPS

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

The appropriate dosage and duration of treatment will be established by your doctor.

When Dorzolamide eye drops are used alone, the usual dose is one drop in the affected eye(s) three times a day, for example in the morning, in the afternoon and in the evening.

If your doctor has recommended you use Dorzolamide eye drops with a beta-blocker eye drop (medicines which lower the pressure of the eye), then the usual dose is one drop of Dorzolamide eye drops in the affected eye(s) two times a day, for example in the morning and in the evening.

If you use Dorzolamide eye drops with another eye drop, leave at least 10 minutes between putting in Dorzolamide eye drops and the other medicine. Alternatively if you are going to use Dorzolamide eye drops to replace another eye drop medicine, used to lower eye pressure, you should stop using the other medicine after taking the proper dosing on one day, and start Dorzolamide eye drops on the next day.

Do not change the dosage of the drug without consulting your doctor. If you must stop treatment, contact your doctor immediately.

Do not allow the tip of the container to touch your eye or areas around your eye. It may become contaminated with bacteria that can cause eye infections leading to serious damage of the eye, even loss of vision. To avoid possible contamination of the container, keep the tip of the container away from contact with any surface.

Instructions for proper use:

It is recommended that you wash your hands before putting in your eye drops.

It may be easier to apply your eye drops in front of a mirror.

1.    Before using the medication for the first time, be sure that the tamper-proof seal on the bottle neck is unbroken. A gap between the bottle and the cap is normal for an unopened bottle.

2.    Take off the cap of the bottle.

3.    Tilt your head back and gently pull your lower eyelid down to form a small pocket between your eyelid and your eye.

4.    Turn the bottle upside down, and squeeze it until a single drop is dispensed into the eye as directed by your doctor. DO NOT TOUCH YOUR EYE OR EYELID WITH THE DROPPERTIP

5.    Repeat steps 3 & 4 with the other eye if instructed to do so by your doctor.

6.    Put the cap back on and close the bottle straight after you have used it.

If you use more Dorzolamide eye drops than you should

If you put too many drops in your eye or swallow any of the contents, you should contact your doctor immediately.

If you forget to use Dorzolamide eye drops

It is important to use Dorzolamide eye drops as prescribed by your doctor.

If you miss a dose, use it as soon as possible. However, if it is almost time for the next dose, skip the missed dose and go back to your regular dosing schedule.

Do not use a double dose to make up for forgotten individual doses.

If you stop using Dorzolamide eye drops
