Dorzolamide / Timolol Actavis used to lower an elevated pressure in the eye in glaucoma ( glaucoma ) when treatment with eye drops containing only beta-blocker is not sufficient.
Dorzolamide and timolol contained in Dorzolamide / Timolol Actavis may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.
