CLENBUTEROL-INDUCED TARDIVE-DYSKINESIA

A 73-year-old man with a history of obstructive lung disease who received clenbuterol 20 mg b.i.d. over 5 years developed dyskinetic movements mainly of the respiratory muscles, closely resembling neuroleptic-induced dyskinesias. Despite drug withdrawal, abnormal movements persisted unchanged. Treatment with reserpine successfully controlled the dyskinetic movements. Clinicians should be aware of this potentially harmful effect of long-term clenbuterol therapy.
