when "pseudo-parkinsonism" follows full tranquilizer dosage...   add COGENTIN® Mesylate benztropine mesylate
Cogentin® Mysylate (benztropine mesylate) usually relieves drug-induced, or "pseudo-," parkinsonism (extrapyramidal reactions to full tranquilizer dosage that may appear as muscular rigidity, gait disturbances, tremor at rest, or drooling). With Cogentin most patients can continue tranquilizer therapy with no reduction in dosage. Cogentin also acts promptly against other extrapyramidal effects of tranquilizers, such as dystonic reactions and akathisia.
When oral use of Cogentin is difficult or impossible (as in acute dystonic attacks) or when rapid response is essential, Injection Cogentin often produces dramatic relief of symptoms. Recurrence of extrapyramidal reactions can generally be prevented by administration of Cogentin tablets.
