How should you take Dorzolamide hydrochloride, Timolol maleate?
Although Cosopt is an eyedrop, the medications it contains affect the entire body. In rare cases, the timolol in Cosopt has caused fatal asthma attacks and heart failure. The dorzolamide it contains has been known to cause fatal allergic reactions. If you develop hives, blisters, swollen eyelids, inflamed eyes, or any other sign of an allergic reaction, stop using Cosopt and check with your doctor immediately. If you are planning to have surgery, make sure the doctor knows you are using Cosopt. Your dose may be gradually lowered in preparation for the operation. Also alert the doctor immediately if you sustain an eye injury or infection. Use Cosopt with caution if you have diabetes or a thyroid condition. It can mask some of the signs of these disorders. Caution is also warranted if you have myasthenia gravis; in rare cases, Cosopt may increase muscle weakness. If you have severe kidney disease, make sure the doctor knows about it. Cosopt is not recommended under these circumstances.
