[Drug-induced tremor]

Abstract

Drug-induced tremor is an important differential diagnosis for tremor syndromes. In view of a constantly ageing population and increasingly frequent polypharmacotherapy, identification of potentially tremor-inducing drugs may help generating risk profiles for individual patients. Drug-induced tremor has often been seen as a complication of antipsychotic therapy, but its occurrence has also been described in response to a great diversity of compounds such as antidepressants, sympathomimetics, antiarrhythmics, antiepileptics and other drugs. The present article presents a synopsis of the most prevalent tremor-inducing drugs as well as strategies to overcome drug-induced tremor, either by replacement of the causative drug or by symptomatic therapies.
