Antimuscarinics (Includes Artane) ↔ Psychoses

Moderate Potential Hazard, Moderate plausibility

Applies to: Psychosis

Toxic psychosis manifested as confusion, disorientation, agitation, excitation, memory impairment, delusions and hallucinations may develop at toxic and therapeutic dosages of antimuscarinic agents. Therapy with these agents should be administered cautiously in patients with mental disorders receiving antimuscarinic agents for control of drug-induced extrapyramidal effects, especially at the beginning of therapy or during dosage adjustment. Psychiatric deterioration and psychotic flare-ups have also been reported following withdrawal of therapy. Symptoms include delusions, hallucinations, aggression or violent behavior, and suicidal tendencies. In high dosages, antimuscarinic agents may sometimes produce euphorigenic effects. For this reason, it can be a drug of abuse.
