USADA site
S9. Glucocorticoids
The systemic use of glucocorticoids (often called “steroids” by prescribers) is prohibited in-competition. WADA defines systematic routes as oral intake (taken by mouth and swallowed, e.g. Medrol Dose Pak), a systemic injection into the vein (IV) or muscle (IM), or rectal use.
Advisory:
An athlete who is prescribed oral, rectal, IV, or IM glucocorticoids may take these medications out-of-competition without submitting a TUE, as long as the prohibited substance has cleared their system prior to the time defined as “in-competition.” If an athlete needs to use these routes of administration shortly before or during competition, he or she must obtain a TUE.
The time it takes for glucocorticoids to clear from an athlete’s body depends on many variables and cannot be predicted by USADA. An athlete’s doctor or pharmacist can help determine the medication’s clearance time. Read the Clearance Time FAQ on the TUE page.
Injections of glucocorticoids around tendons, into joints, and epidural spaces (into the spine) are not prohibited, but an injection into a muscle is prohibited.
Inhalation of glucocorticoids (e.g. for asthma) is permitted.
Topical use of glucocorticoids (e.g., anti-rash cream, hemorrhoid creams used on the surface, etc.) are not prohibited. Be aware, however, that some hemorrhoid suppositories or inserted rectal creams contain glucocorticoids and are prohibited in-competition.
On the
WADA site S9 GLUCOCORTICOIDS appear under "prohibited in-competition" but do not appear under "prohibited at all times"
@dellzeqq As to the definition of "in-competition" I found this on the
UKAD site
WADA define in-competition as “the period commencing 12 hours before competition… through to the end of such competition and the sample-collection process related to such competition”, unless stated otherwise by the rules of an IF or other relevant anti-doping organisation.
