How Does Dorzolamide Work?Dorzolamide belongs to a group of drugs called carbonic anhydrase inhibitors. Carbonic anhydrase is an enzyme found in many places throughout the body, including the eye. By inhibiting this enzyme, dorzolamide lowers the eye pressure by decreasing the amount of fluid the eye produces (known as aqueous humor).
When and How to Use ItGeneral considerations to keep in mind during treatment with dorzolamide include the following:
- This medication comes in the form of an eye drop. It is used in the affected eye(s) three times a day.
- Soft contact lenses can absorb the preservative (benzalkonium chloride) in these eye drops. In order to avoid this problem, you must remove the lenses before using dorzolamide and wait at least 15 minutes before reinserting them.
- If you use other eye drops in addition to dorzolamide, make sure to wait at least 10 minutes between using dorzolamide and the other eye medication.
- In order to prevent contamination of the drops, do not touch the tip of the dropper to any surface, including the surface of the eye or the skin.
- For dorzolamide to work properly, it must be taken as directed.
