Dorzolamide Ophthalmic (patient information)

Why this medication is prescribed

Dorzolamide is used to treat glaucoma, a condition in which increased pressure in the eye can lead to gradual loss of vision. Dorzolamide decreases the pressure in the eye.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How this medication should be used

Dorzolamide comes as eyedrops. Dorzolamide eyedrops usually are applied three times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use dorzolamide exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Dorzolamide controls glaucoma but does not cure it. Continue to use dorzolamide even if you feel well. Do not stop using dorzolamide without talking to your doctor.

To use the eyedrops, follow these instructions:

Wash your hands thoroughly with soap and water.
Use a mirror or have someone else put the drops in your eye.
Remove the protective cap. Make sure that the end of the dropper is not chipped or cracked.
Avoid touching the dropper tip against your eye or anything else.
Hold the dropper tip down at all times to prevent drops from flowing back into the bottle and contaminating the remaining contents.
Lie down or tilt your head back.
Holding the bottle between your thumb and index finger, place the dropper tip as near as possible to your eyelid without touching it.
Brace the remaining fingers of that hand against your cheek or nose.
With the index finger of your other hand, pull the lower lid of the eye down to form a pocket.
Drop the prescribed number of drops into the pocket made by the lower lid and the eye. Placing drops on the surface of the eyeball can cause stinging.
Close your eye and press lightly against the lower lid with your finger for 2-3 minutes to keep the medication in the eye. Do not blink.
Replace and tighten the cap right away. Do not wipe or rinse it off.
Wipe off any excess liquid from your cheek with a clean tissue. Wash your hands again.

Special precautions

Before using dorzolamide eyedrops:

tell your doctor and pharmacist if you are allergic to dorzolamide, other antibiotics, sulfa drugs, or any other drugs.
tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially eye medications, products that contain aspirin, and vitamins.
tell your doctor if you have or have ever had kidney disease.
tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using dorzolamide, call your doctor immediately.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are using dorzolamide.
if you are using another eyedrop medication, use the eye medications at least 10 minutes apart.
tell your doctor if you wear soft contact lenses. Wait at least 15 minutes after using the medicine to put in soft contact lenses.

What to do if you forget a dose

Apply the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not apply a double dose to make up for a missed one.
