Description
Indications
Dorzolamide is prescribed for the management of elevated intraocular pressure associated with conditions like open-angle glaucoma or other eye disorders such as ocular hypertension. Its primary goal is to mitigate the risk of vision loss. The mechanism of action involves a reduction in the quantity of fluid present in the eye. This medication falls under the category of carbonic anhydrase inhibitors.
Uses and Dosage
Administer this medication in the affected eye(s) according to your doctor’s instructions, typically applying one drop three times a day.
Before using eye drops, ensure that you wash your hands thoroughly. To prevent contamination, avoid contact between the dropper tip and your eye or any other surface.
If your eye drops contain a preservative, be mindful that it may be absorbed by contact lenses. If you wear contact lenses, take them out before using the eye drops with preservatives. Wait for at least 15 minutes after applying this medication before reinserting your contact lenses.
If you are using another type of eye medication, such as drops or ointments, wait for a minimum of 10 minutes before applying additional medications. Prioritize using eye drops before eye ointments to allow the drops to enter the eye effectively.
Consistently use this medication to derive optimal benefits. Establish a routine by using it at the same times each day.
Even if you feel well, continue using dorzolamide, as individuals with glaucoma or elevated eye pressure may not experience noticeable symptoms.
To administer the eye drops, the following steps should be followed:
- Thoroughly wash hands with soap and water.
- Do not allow the dropper tip to touch the eye or any other surface, and ensure that it is kept clean.
- Tilt the head back and pull down the lower lid of the eye using the index finger to form a pocket.
- Hold the dropper as close to the eye as possible without making contact, and brace the remaining fingers against the face.
- Squeeze the dropper gently to instill a single drop in the pocket created by the lower eyelid while looking upwards.
- Remove the index finger from the lower eyelid and keep the eye closed for 2-3 minutes while tilting the head down.
- Apply gentle pressure to the tear duct using a finger.
- Use a tissue to wipe off any excess liquid from the face.
- Wash hands to remove any residual medication.

FAQ
How long does it take Trusopt to work?
Trusopt typically lowers eye pressure within 2 hours after each dose. It can take several weeks for the pressure to be consistently lower on this medication, so your provider will re-check your eye pressure after you have been using Trusopt for about 8 weeks.
Can Trusopt cause fatigue?
Even though Trusopt is an eye drop, it is possible for some of the medication to be absorbed into your bloodstream and affect other areas of the body. Fatigue is a potential side effect from using Trusopt, though it happens rarely.
