A 56 year old patient with psychiatric complications of systemic lupus
erythematosus developed severe dysphagia complicated by weight loss a
nd aspiration. Following investigation it was concluded that the addit
ion of haloperidol to her treatment was the major precipitating cause
and withdrawal of the drug was followed by an objective improvement in
swallowing. Patients taking major transquillizers may be at increased
risk of severe dysphagia; regular observation of swallowing is sugges
ted as a useful addition to the clinical examination of these patients
