Cosopt Preservative Free contains 2 active ingredients that will help to lower the elevated intraocular pressure in your eye caused by open-angle glaucoma. Dorzolamide HCl is a carbonic anhydrase blocker and Timolol Maleate is a beta blocker. As the Cosopt Preservative Free name indicates, there is no benzalkonium chloride in this formulation. This is beneficial to everyone using it, but especially those with ocular surface disease (OSD) as preservatives can make some eye meds difficult to tolerate.
Dorzolamide HCl will block the secretion of fluid within your eye in order to lower the intraocular pressure (IOP). Timolol Maleate will block the beta receptors in your eye so the inflow of aqueous humor into your eyeball is decreased which also helps to decrease the pressure.
You can also minimize side effects if you instill Cosopt Preservative Free as instructed and then close your eyes and place a finger to the inside corner of your eye for a 2 full minutes as this is the time it takes for the eye drop to fully penetrate your eye surface. This can greatly reduce side effects to other parts of your body as this method can prevent the medication from getting into your nose and entering the bloodstream.
The most common form of glaucoma is open-angle glaucoma, which accounts for about 90% of these cases. This is a lifelong and slowly developing condition caused as the drainage canals become blocked so the fluid buildup increases and causes pressure inside your eye. Unless this pressure is reduced, it can eventually cause damage to your optical nerve.
Open-angle indicates the angle of where your iris meets the cornea is as wide and open as it is supposed to be. Regular eye exams are essential as you get older so your ophthalmologist can spot trouble before your sight is threatened.
Before using Cosopt Preservative Free, ask your doctor if there are any risks to an unborn or nursing baby if you are pregnant, trying to become pregnant, or are breast feeding. Discuss with your doctor other medical conditions or allergies you have and list any OTC or Rx drugs you currently take or use, including herbal and vitamin supplements. This will determine if Cosopt Preservative Free is safe for you to use.
Do not drive, operate machinery, or attempt any task until your vision has cleared after using Cosopt Preservative Free. Keep this, and other medications, out of children’s reach. Cosopt Preservative Free is supplied in individual doses so only open 1 container as needed and do not save any contents that remain after each dose.
