1. WHAT DORZOLAMIDE IS AND WHAT IT IS USED FOR
Dorzolamide is a sterile eye drop solution. Dorzolamide contains dorzolamide, which belongs to a group of medicines called “carbonic anhydrase inhibitors”.
This medicine is prescribed to lower raised pressure in the eye and to treat glaucoma. This medicine 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:
Warnings and precautions
Talk to your doctor or pharmacist before using Dorzolamide about any medical problems you have now or have had in the past, including eye problems and eye surgeries, and about any allergies to any medications.
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 eyelids.
Stop using Dorzolamide and contact your doctor immediately if you suspect that Dorzolamide is causing an allergic reaction (for example, skin rash, severe skin reaction or itching).
Dorzolamide has 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.
In studies with dorzolamide, the effects of this medicine were similar in both elderly and younger patients.
Patients with liver impairment
Tell your doctor about any liver problems you now have or have suffered from in the past.
Other medicines and Dorzolamide
Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines (including eye drops).
This is particularly important if you are taking another carbonic anhydrase inhibitor such as acetazolamide, or a sulpha medicine.
Pregnancy and breast-feeding
You should not use this medicine during pregnancy. If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
If treatment with this medicine is required, breast-feeding is not recommended. Tell your doctor if you are breast-feeding or intend to breast-feed.
Driving and using machines
No studies on the effects on the ability to drive or use machines have been performed. There are side effects associated with this medicine, such as dizziness and blurred vision, which may affect your ability to drive and/or operate machinery. Do not drive or operate machinery until you feel well or your vision is clear.
Dorzolamide contains the preservative benzalkonium chloride
This medicine contains 0.075mg benzalkonium chloride in each ml of solution.
Benzalkonium chloride 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 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 dose and duration of treatment will be established by your doctor.
When Dorzolamide is used alone, the recommended dose is one drop in the affected eye(s) in the morning, in the afternoon and in the evening.
If your doctor has recommended you use Dorzolamide with a beta-blocker eye drop to lower eye pressure, then the recommended dose is one drop of Dorzolamide in the affected eye(s) in the morning and in the evening.
If you are using Dorzolamide with another eye drop, the drops should be instilled at least 10 minutes apart.
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. If you think your medicine may be contaminated, or if you develop an eye infection, contact your doctor immediately concerning continued use of this bottle.
Instructions for 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 medicine 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 DROPPER TIP.
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 than you should
If you put too many drops in your eye or swallow any of the contents of the container, you should contact your doctor immediately.
