Conditions in which inhibition of the parasympathetic nervous system is undesirable, such as tachycardia and urinary retention (such as may occur with marked prostatic hypertrophy), require special care in the administration of the drug. Hypotensive patients who receive the drug should be observed closely. Occasionally, particularly in older patients, mental confusion and disorientation may occur with the development of agitation, hallucinations, and psychotic-like symptoms.
Patients with mental disorders occasionally experience a precipitation of a psychotic episode when the dosage of antiparkinsonism drugs is increased to treat the extrapyramidal side effects of phenothiazine and rauwolfia derivatives.
