Cosopt is a combination medicine consisting of dorzolamide and timolol. Dorzolamide ophthalmic is used to treat glaucoma and other causes for excessive high pressure in the eye. Cosopt may have other purposes not covered in this guide. Timolol ophthalmic is a beta-blocker that also decreases the pressure within the eye.
Children under two should not use Cosopt.
Follow your doctor’s guidance carefully, along with any instructions included with the medicine.
Wash your hands before applying eye drops:
1. Tilt your head back and pull down the lower eyelid. Look up when you squeeze the eye dropper.
2. Close your eyes for two to three minutes with head tipped down. Keep liquid from draining by pressing a finger to the inside corner of the eye for one minute.
3. Wait at least five minutes between drops. Wait at least 10 minutes before using other prescribed eye drops.
If you miss a dose, take it as soon as you remember, but skip a missed dose if it’s almost time for your next dose.
Do not use Cosopt while wearing contact lenses. Wait for at least 15 minutes before putting your contact lenses back in. Do not use more than the number of drops prescribed.
Cosopt should be stored at room temperature, away from light, moisture, and heat.
Contact your doctor immediately if you suffer an eye injury or infection, or if you have any type of surgery (especially eye surgery).
Do not use Cosopt if you are allergic to dorzolamide or timolol. Also, do not use Cosopt if you have a history of asthma, COPD, a serious heart condition, or a recent heart attack. Furthermore, don’t use other eye medications while you’re using Cosopt unless otherwise directed by your doctor.
Before starting this medication, inform your doctor of your medical history, especially if you’ve experienced: narrow-angle glaucoma, breathing problems, diabetes, a history of heart disease or congestive heart failure, kidney or liver disease, a muscle disorder, or a thyroid disorder.
Cosopt’s effect on pregnancy is unknown. Tell your doctor if you are pregnant, plan to be, or if you breast-feed.
Cosopt may make vision blurry, use caution when driving or doing anything that requires alertness or vision.
Find emergency medical assistance if you notice allergic reaction symptoms, such as hives and swelling.
While serious side effects are rare, you can still suffer side effects if dorzolamide gets absorbed into your bloodstream. Cease use and contact your doctor immediately if you experience: swollen or red eyelids, pain, and discomfort in the eyes, sensitivity to light, crusting and oozing from eyes, breathing issues, swelling, rapid weight gain, shortness of breath, and a severe skin reaction.
Other common side effects include an unusual or bitter taste in your mouth, blurry vision, or burning and itching in the eyes.
These symptoms include shortness of breath, muscle pain/weakness, fast or slow heart rate, confusion, breathing difficulties, chest pain, convulsions, and fainting.
Other eye medications should not be used alongside Cosopt unless otherwise directed by your doctor.
Cosopt may interact with other drugs. Inform your doctor of other drugs you take, including over-the-counter meds, supplements, herbs, and vitamins.
