Dexamethasone (Dexa-meth-ah-zone) is a medicine which is used in a number of conditions.
The information in this Medicine Guide for Dexamethasone varies according to the condition being treated and the particular preparation used.
Information specific to Dexamethasone 0.1% eye drops when used in Eye surgery and procedures
Dexamethasone is a corticosteroid. Dexamethasone works by preventing or reducing inflammation. It is used to treat a number of conditions that are characterised by excessive inflammation.
People who take corticosteroids for a long period of time are prone to infections as their immune system can become weak. These infections may be much more severe than they usually would be and the symptoms that would usually be used to identify such infections can be hidden.
When Dexamethasone is being used in the eye, Dexamethasone may still be absorbed into the body causing side effects. When it is used over a long period of time or in large amounts, the amount of Dexamethasone that is absorbed into the body increases. This increases the chances of Dexamethasone causing side effects in areas of the body other than the eye.
