Dorzolamide is a medicine used to manage high eye pressure. Lowering the amount of fluid produced within the eye, the solution protects the optic nerve from damage.
Dorzolamide belongs to a class of medicines called carbonic anhydrase inhibitors, which reduce fluid buildup in the eye. It is the ingredient that makes medicines such as Cosopt and Trusopt work to protect your vision.
Dorzolamide-containing eye drops are used for high eye pressure, often called ocular hypertension, or for open-angle glaucoma. This medicine is also used when you need an additional pressure-lowering effect alongside another eye-drop treatment. It can help adults who experience blurry vision caused by fluid excess, and it may be used after eye surgery to keep pressure down.
Dorzolamide blocks an enzyme called carbonic anhydrase in the eye. With that enzyme blocked, less fluid is produced, pressure drops, and fluid flows out of the eye more smoothly, keeping internal pressure at a more appropriate level.
Pregnant or breastfeeding people, individuals with severe kidney problems, and those who are allergic to sulfonamide drugs may need an alternative. Alcohol and some systemic medicines, such as other carbonic anhydrase inhibitors, can increase the chance of side effects, so check the labeling of any other product you take. Always read the specific medication's label for a complete list of possible interactions.
Older adults and people with existing kidney disease tend to report side effects more often. Individuals who are also using other eye-drop medicines or systemic carbonic anhydrase inhibitors may experience stronger reactions.
Store dorzolamide eye drops at room temperature, away from direct sunlight and excess moisture. Most formulations are meant for short-term use after opening, typically up to 30 days, but some products may be labeled for longer periods. Each brand, such as Cosopt or Trusopt, can differ in strength and directions.
For Dorzolamide-specific instructions, refer to the medication information supplied with the product.
Carbonic anhydrase inhibitor: A type of medicine that reduces fluid production in the eye by blocking a specific enzyme. Intraocular pressure: The fluid pressure inside the eye, which must stay within a normal range to protect vision. Ophthalmic solution: A sterile liquid formulation meant to be applied directly to the eye as drops.
