1. What Dorzolamide is and what it is used for
Dorzolamide is a sterile eye drop solution. Dorzolamide contains 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 indicated in the treatment of elevated intra-ocular pressure in conditions such as ocular hypertension and glaucoma (open-angle glaucoma, pseudo-exfoliative glaucoma). Dorzolamide can be used alone or in addition to other medicines which lower the pressure in the eye (so-called beta-blockers).
2. What you need to know before you use Dorzolamide Do not use Dorzolamide
- if you are allergic to dorzolamide or any of the other ingredients of this medicine (listed in section 6)
- if you have severe kidney problems
- if you have a disturbance in the pH (acid/alkali balance) of your blood.
Warnings and PrecautionsTalk to your doctor before using Dorzolamide
- if you have or have had liver problems in the past
- if you have been told you have a corneal defect
- 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 another carbonic anhydrase inhibitor
- if you wear contact lenses (see the section 'Important information about some of the ingredients of Dorzolamide).
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 and contact your doctor immediately if you suspect that Dorzolamide is causing an allergic reaction (for example, skin rash or itching, inflammation of the eye).
Children and adolescents
Dorzolamide should only be used in children if the benefits outweigh the risks. Your doctor will be able to advise you.
Other medicines and Dorzolamide
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, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.
Dorzolamide should not be used during pregnancy unless your doctor still recommends it.

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

• Benzalkonium chloride may cause eye irritation
• Benzalkonium chloride is known to discolour soft contact lenses

3. How to use Dorzolamide
Always use this medicine exactly as your doctor has told you. 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 is 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 with a beta-blocker eye drop (medicines which lower the pressure of the eye), then the usual dose is one drop of Dorzolamide in the affected eye(s) two times a day, for example in the morning and in the evening.
If you use Dorzolamide with another eye drop, leave at least 10 minutes between putting in Dorzolamide and the other medicine. Alternatively if you are going to use Dorzolamide 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 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. Invert the bottle 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 DROPPER TIP.
5. Repeat steps 2 & 3 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 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
It is important to use Dorzolamide 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 take a double dose to make up for a forgotten dose.
If you stop using Dorzolamide
Dorzolamide should be used every day to work properly. If
you must stop treatment, contact your doctor immediately.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
