Increased anticholinergic side effects with drugs with anticholinergic properties.
Potentially Fatal: Antagonises effect of apomorphine, levodopa and other dopamine agonists. Increased risk of blood dyscrasias with clozapine. Increased risk of arrhythmias with dugs that prolong QT interval e.g. class Ia and III antiarrhythmics, erythromycin or cause electrolyte disturbances e.g. thiazide diuretics.
