A man consumed MDMA and Amphetamine. Though both were below toxic levels in
blood, the combined level of .3 mg/kg was above toxic threshold of .2
"The treatment of MDMA-related morbidity should be early and aggressive and
includes: gastric lavage, chlorpromazine, adrenergic blockade, intravenous
fluids and passive cooling". An afternote says "The National Poisons
Information Service now advocates the early use of dantrolene in the
management of severe complications following Ecstasy. Chlorpromazine may
lower the convulsive threshold and is no longer advised."
