Dorzolamide/timolol drops are absorbed into your bloodstream and can interact with a number of prescription drugs, over the counter medicines, foods, and herbal supplements. Your doctor may need to change the dose or otherwise modify your dorzolamide/timolol treatment if you are taking medications that lower blood sugar (e.g. insulin or oral diabetes medications) because of an increased risk of low blood sugar and slowed heart rate. Other medications (SSRI antidepressants, clonidine, quinidine, reserpine, digitalis, verapamil) may cause serious cardiovascular problems when mixed with dorzolamide/timolol. Salicylates (e.g. aspirin) and oral carbonic anhydrase inhibitors may be more likely to cause side effects if they are taken with this drug, and beta-blocker (both oral and other eye drops) side effects may also be exacerbated when taken with dorzolamide/timolol. Dorzolamide/timolol drops can decrease the effectiveness of some drugs (e.g. albuterol, epinephrine).
