Combipat Ophthalmic Solution 5 ml is used to treat allergic eye disease. It contains Ketorolac and Olopatadine, which works by blocking the release of several chemical messengers that cause inflammation (redness and swelling), and pain in the eye. It may cause side effects such as burning sensation, eye pain, eye discomfort, eye irritation, headache, dry nose, and taste change. Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
