Tremor is a common adverse effect of prescribed drugs. It also occurs following
exposure to various environmental or occupational toxins and poisons. Given that
tremor is a prevalent condition that may exist in patients not on medications, it is
often difficult to determine if a drug is responsible for a patient’s tremor.
Occasionally, neurological examination is performed prior to and after starting
a drug making assumptions about causality more tenable. In addition, some
patients are on multiple drugs that can cause or exacerbate tremor and identifying
a single drug as the culprit is often difficult. In this chapter we will attempt to
identify the drugs and toxins most commonly associated with inducing or exacer-
bating tremors.
