A form of water tablet, called Diamox, may be useful to help control the pressure in some cases. The tablets are usually a short-term treatment.

The tablet reduces the production of fluid in the eye and increases the amount of urine and salts leaving the body. If the tablets are used for more than a week, it is a good idea to eat a banana a day to help replace some of the salts.

The tablets can cause some patients to experience tingling in their hands, feet and lips, or nausea and tiredness. They may cause kidney stones in some patients after prolonged use. If you notice these side-effects, tell your doctor.
