title: Lithium tremor.
abstract: BACKGROUND
  Tremor is a common problem for patients taking lithium, but little is known about its true prevalence, its effect on compliance, and effective treatments.
  
  
  METHODS
  The data base of the Lithium Information Center in Madison, Wis., was searched for articles relating to lithium tremor.
  
  
  RESULTS
  Studies show a wide range of incidence of lithium tremor--4% to 65%--due to differences in defining and reporting this side effect. While lithium tremor often decreases with time on lithium, other treatment options include changing the dose or preparation of lithium, decreasing or eliminating other drugs, and treating with beta-blocking drugs, primidone, fatty acids, or potassium. Severe tremor may be a sign of lithium toxicity.
  
  
  CONCLUSIONS
  Patients should be evaluated for lithium tremor on a regular basis. Diagnostic criteria should be standardized by a double-blind, random assignment, multicenter study that could also investigate proposed treatments.
