Substances: Ephedrine

Ephedrine is a central nervous system stimulant first produced from the ephedra plant 5000 years ago. It is often found in Chinese herbal preparations and therefore use of these herbs can lead to a positive drug test.

Ephedrine is a sympathomimetic agent. This means it is a stimulant whose mechanism of action mimics adrenaline or amphetamines as it stimulates the same type of drug receptors. The effects of ephedrine, however, are much less pronounced than amphetamine.

Side effects

Side effects are common with ephedrine use. Side effects include increased heart rate, palpitations, heart irregularities, tremor, insomnia, increased sweating and trouble with heat regulation.

Ephedrine commonly causes an increase in blood pressure and may increase anxiety and alter judgement. Drug addiction and death are being more commonly reported in sport.

Status in Sport

Ephedrine is prohibited in competition only under the World Anti-Doping Code 2007 Prohibited List (effective 01/01/07).
