Signs and symptoms of acute overdosage, resulting principally from overstimulation of the central nervous system and from excessive sympathomimetic effects, may include the following: vomiting, agitation, tremors, hyperreflexia, muscle twitching, convulsions (may be followed by coma), euphoria, confusion, hallucinations, delirium, sweating, flushing, headache, hyperpyrexia, tachycardia, hypertension and mydriasis. Consult with a Certified Poison Control Center regarding treatment for up to date guidance and advice. Treatment consists of appropriate supportive measures. The patient must be protected against self-injury and against external stimuli that would aggravate overstimulation already present. Gastric contents may be evacuated by gastric lavage. Other measures to detoxify the gut include administration of activated charcoal and a cathartic. Chlorpromazine has been reported in the literature to be useful in decreasing CNS stimulation and sympathomimetic effects.

Efficacy of peritoneal dialysis or extracorporeal hemodialysis for CYLERT (pemoline) overdosage has not been established.

CYLERT (pemoline) is contraindicated in patients with known hypersensitivity or idiosyncrasy to the drug. CYLERT (pemoline) should not be administered to patients with impaired hepatic function (see ADVERSE REACTIONS).
