Cosopt (dorzolamide + timolol)
Also known as Dorzolamide Timolol, Cosopt Eye Drops, Combination Glaucoma Drop, Preservative-Free Cosopt
Bottom Line
Cosopt combines two glaucoma medicines in one bottle. It is useful for pressure control, but it carries timolol heart and breathing warnings.
Cosopt contains dorzolamide and timolol. The label lists it for lowering high eye pressure in open-angle glaucoma or ocular hypertension when beta-blocker treatment alone is not enough 1.
The label dose is one drop in the affected eye two times daily 1.
Cosopt is not for people with asthma, severe chronic lung disease, slow heartbeat, heart block, heart failure, cardiogenic shock, or allergy to its ingredients.
Cost and Insurance
Cosopt has brand, generic, and preservative-free versions. Coverage and copays can differ by version.
Ask whether your plan prefers separate dorzolamide and timolol bottles or one combination bottle.
How It Works
Cosopt combines dorzolamide and timolol. Both lower eye pressure by reducing fluid made inside the eye.
One bottle can be simpler than two separate bottles. It still brings safety issues from both medicines.
Who Should Avoid It
The label says Cosopt is not for people with asthma or severe chronic lung disease. It is also not for slow heartbeat, heart block, heart failure, cardiogenic shock, or allergy to any component 1.
Tell your doctor about sulfa drug reactions, kidney disease, liver disease, diabetes, thyroid disease, and planned surgery.
Side Effects
The label lists bitter or unusual taste, burning, stinging, redness, blurred vision, surface keratitis, and itching among common reactions 1.
Call your doctor for wheezing, fainting, chest pain, severe rash, swollen lids, or worsening vision.
