What is COSOPT 20 mg/ml + 5 mg/ml eye drops?
COSOPT is an eye drop solution that combines two active ingredients: dorzolamide hydrochloride and timolol maleate. The combination is used to help lower raised pressure inside the eye.

Use the drops exactly as directed by the prescriber or pharmacist. The original content highlights the following general administration steps:
- Wash your hands before use.

- Close the eye and press gently on the inner corner for a short time to reduce drainage.
