What is a wash-out treatment and why might I need it?
Leflunomide can remain in the body for up to a year after you stop taking it.
In some circumstances it's recommended that leflunomide is eliminated from the body more quickly for example if:
- you become pregnant
- you have severe side-effects from leflunomide
- you need to start another treatment that could interact with leflunomide.
A wash-out treatment will help to remove leflunomide from your body more quickly than usual. This involves taking a drug called cholestyramine for 11 days. You may have blood tests to check that the level of leflunomide in your body is falling.
