indications for Dorzolamide Ophthalmic

Glaucoma is a condition in which an eye disease that damages the optic nerve, and because of that, if it is left untreated, can cause a loss of vision. Since on of the most common causes of glaucoma is the overproduction of fluid inside the eye, drugs like dorzolamide ophthalmic can help by dampening the ability of the aqueous humor to produce the fluids in question. A topical carbonic anhydrase inhibitor, dorzolamide ophthalmic is used mainly to prevent the spread of glaucoma to the unaffected eye of a patient with glaucoma, however it can also be used to treat secondary glaucoma.


Dorzolamide ophthalmic should be used cautiously in pregnant or nursing pets, and in pets with liver and/or kidney disease. Do not give dorzolamide ophthalmic to pets with an allergy to sulfonamides, furosemide, thiazide diuretics, diabetes medicines, or carbonic anhydrase inhibitor-type glaucoma medication.


1 drop three times a day, adjusting dosage based on your pets response to the therapy.
