Drug-Induced Tremors

Drug-induced tremors are common in clinical practice, but often underrecognized or misdiagnosed. There are a myriad of drugs that can cause or exacerbate tremors, making the diagnosis difficult. Many tremorigenic drugs are frequently and widely prescribed, such as amiodarone, valproic acid, lithium, bronchodilators, antipsychotics, and antidepressants. Little is known regarding the mechanism by which these drugs cause tremor; however, it is important for clinicians to recognize potential tremorigenic drugs and develop management strategies for symptomatic patients.
