DORZOLAMIDE-TIMOLOL EYE DROPS

What it is

DORZOLAMIDE-TIMOLOL EYE DROPS is how the CMS NADAC file names this product. The FDA NDC Directory lists it as “dorzolamide hydrochloride and timolol maleate”, “dorzolamide hydrochloride and timolol maleate ophthalmic solution” and “dorzolamide hydrochloride timolol maleate”, as its NDCs’ listings variously write the nonproprietary name, under the trade name “Dorzolamide and Timolol”.

FDA gives its dosage form as “solution/ drops” and “solution” and its route as ophthalmic.

FDA lists 8 labelers (the companies named on the label) for its NDCs, among them Bausch & Lomb Incorporated, Micro Labs Limited and Sandoz Inc.

FDA lists it under 2 Established Pharmacologic Classes: beta-Adrenergic Blocker and Carbonic Anhydrase Inhibitor.

The NADAC file of 2026-10-14 prices it under 9 NDCs (National Drug Codes); the FDA directory lists 8 of them.

NADAC classes it as a generic drug (rate-setting class G), and does not mark it as sold over the counter.

What to ask at the counter

None of these figures is your price: what you pay depends on your pharmacy, your insurance, coupons and discounts.

• What is your cash price for 10 mL? Is it lower than what I would pay through my insurance?
• How much is in the package I am getting? This page uses 10 mL; your package may hold a different amount.
• If you have Medicare Part D: what is my plan’s copay or coinsurance for it? The Part D average on this page is not what you pay.
• These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
