Abstract
Lithium is a drug used extensively in psychiatry for the treatment of depression, acute mania, and the prophylaxis of recurrent affective disorders. Lithium also has a place in the management of schizoaffective disorders and has been suggested for aggression and alcoholism. The side-effects, dangers of toxicity, and need for monitoring are well documented and should be considered before starting anyone on lithium. Likewise patients should be adequately informed of the benefits and hazards of treatment.
