How Drugs Affect You : Beta 2 Agonists

Fact sheet

Examples: clenbuterol, fenoterol, terbutaline, salbutamol, salmeterol.

Beta 2 agonists are most commonly found in some of the medications used to treat asthma. When given systemically (through the bloodstream), beta 2 agonists may have anabolic effects and therefore their use in sport is banned. They do not, however, have the same side effects on the body as steroidal anabolic agents. Side effects of beta 2 agonists include tremor, tachycardia, palpitations, hypertension, headaches, nausea, flushes, sweating, muscle cramps, twitching, restlessness, dizziness and sleep disturbances.

Terbutaline, salbutamol and salmeterol are the only beta 2 agonists permitted and they are only permitted in inhaler form. Beta 2 agonists are unusual as they are classified as both stimulants and anabolic agents. When taken as aerosols, however, they do not have anabolic effects.

If athletes require salbutamol, terbutaline or salmeterol in inhaler form they will need to check with their national sporting organisation to see if written notification of this use is required prior to the sporting event.

Written notification is required at Olympic games and some other major international events and by specific sports.

At other times, the athlete may be required to carry a letter with them that legitimises the use of salbutamol, terbutaline or salmeterol and produce this letter at the time of a drug test.
