title: Physiological dependence on, and symptoms of withdrawal from, chlormethiazole.
abstract: The uses of chlormethiazole (Heminevrin) are briefly mentioned. Differing views of its potential for producing dependence are discussed. The consensus opinion is taken to be that a risk of psychological dependence does exist, but only one case has appeared in the medical literature to date of physiological dependence on chlormethiazole, with withdrawal symptoms. This case is re-examined. A second case is described in which the features of increasing dosage and withdrawal were followed by confusion, disorientation, delusions, hallucinations and muscular spasm and coarse jerking. This is taken as confirmation of the potential of chlormethiazole to produce physiological dependence. Some personal opinions of the author regarding indications for use and incidence of abuse are briefly mentioned.
