Tremor – drug-induced
Definition of Drug-induced tremor
Drug-induced tremor is involuntary shaking due to the use of medication. Involuntary means you shake without trying to do so. The shaking occurs when you move or try to hold your arms, hands, or head in a certain position. It is not associated with other symptoms.
Causes, incidence, and risk factors
Drug-induced tremor is a simple nervous system and muscle response to certain medications. Drugs that can cause tremor include the following:
The tremor may affect the hands, arms, head, or eyelids. It rarely affects the lower body and may not affect both sides of the body equally.
Signs and tests
Your doctor can make the diagnosis by performing a physical exam and asking questions about your medical and personal history, especially your medication use.
Drug-induced tremor will go away when you stop taking the medicine that is causing the shaking.
Drug-induced tremor is not a dangerous condition, but some patients find the tremor annoying and embarrassing.
