Buspirone-induced jitteriness in three patients with panic disorder and one patient with generalized anxiety disorder.

Three patients with a history of panic disorder and one patient with a history of generalized anxiety disorder were treated with buspirone and experienced an increase in their anxiety levels, agitation, and restlessness and also developed pressured speech and racing thoughts. These symptoms completely resolved after buspirone was discontinued. Jitteriness may have been due to an unusual adrenergic sensitivity in these patients.
