About dorzolamide

Type of medicine Carbonic anhydrase inhibitors
Used for Glaucoma (raised pressure in the eye)
Also called Trusopt
Available as Eye drops

Dorzolamide works by blocking the action of an enzyme in the body called carbonic anhydrase. This results in a decrease in the amount of aqueous humour (watery fluid that fills the space in the front of the eye), and so pressure within the eye is reduced.

Before taking dorzolamide

Before taking dorzolamide make sure your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have liver or kidney problems.
  • If you have had any problems with your eyes, or any operations on your eyes.
  • If you wear contact lenses.
  • If you have ever been allergic to drugs called "sulphonamides".

How to take dorzolamide

  • Follow your doctor's instructions.

Getting the most from your treatment

  • If you are using more than one eye drop, leave at least ten minutes between applications.
  • Avoid allowing the tip of the dispensing bottle to make contact with your eye.
  • Throw away eye drops one month after opening.
  • If you have single-use containers, throw away any unused solution once opened.

PS - Health and Poverty

Perhaps the biggest cause of ill health in the world is poverty. Help to Make Poverty History. For example, why not lend some of your money to disadvantaged communities to enable them to trade their way out of poverty through schemes such as Shared Interest.
