Q. Before an event, should I stop taking medications prohibited in-competition only?
A. If you are using a medication that is prohibited only in-competition, such as a stimulant (e.g. Ritalin, Modafinil, Concerta, Daytrana, Vyvanse), narcotic (e.g. oxycodone, pethidine, methadone and others), cannabinoid (e.g. Marinol and others), or glucocorticoid (e.g dexamethasone, prednisolone and others), you might wonder how long before a competition you need to stop taking your medication to avoid testing positive. The good news is that you can apply for a Therapeutic Use Exemption (TUE) that, if approved, gives you the permission to use your medication in sport so that you do not have to stop taking it.
