A 25 gram tube of Anthisan Cream contains 500mg Mepyramine Maleate. If accidentally ingested this dose would constitute a dangerous overdose in young children.
Overdose may be fatal especially in infants and children. Overdosage is associated with antimuscarinic, extrapyramidal, gastrointestinal and central nervous system effects. In infants and children, central nervous system stimulation predominates over central nervous system depression. This can cause ataxia, excitement, tremors, psychoses, hallucinations, convulsions and hyperpyrexia. Deepening coma and cardiorespiratory collapse may follow. In adults, central nervous system depression is more common with drowsiness, coma and convulsions, progressing to respiratory failure or possibly cardiovascular collapse.
The stomach should be washed out. Stimuli liable to provoke convulsions should be avoided, but if this complication should occur, parenteral diazepam should be given. Sedatives which are liable to increase respiratory depression should be avoided. Other measures such as artificial respiration and oxygen may also be required and an antibiotic can be given as a prophylactic agains pneumonia.
