Prohibited classes of substances and prohibited methods (Olympic movement anti-doping code)

When the administration of a prohibited substance is medically justified and finds no other alternative, the athlete and his physician can request a clearance for use (i.e. insulin). The prescription of asthma medications (formoterol, salbutamol, salmeterol, terbutaline) is authorized by inhalation and with the appropriate notification and documentation. The systemic use of glucocorticosteroids is prohibited when administered orally, rectally, or by intravenous or intramuscular injection. When medically necessary, local and intra-articular injections of glucocorticosteroids are permitted. Where the rules of a responsible medical authority so provide, notification of administration may be necessary.
