Duosopt Eye Drops is a prescription ophthalmic solution in a 5 ml bottle, formulated with dorzolamide 2% w/v and timolol 0.5% w/v in one combination product.
It is used under clinician guidance for intraocular pressure control, with practical handling that includes avoiding contact between the nozzle tip and surfaces to reduce contamination risk.
After opening, keep the bottle tightly closed and discard remaining solution if it becomes cloudy or brown, or after one month of opening.
