No significant interactions described.
4.6 Pregnancy And Lactation
There is no evidence of the safety of mepyramine maleate in human pregnancy, but it has been widely used for many years without apparent ill consequence. Absorption of a significant amount after topical application is unlikely in the prescribed method of use, nevertheless, Anthisan Cream should not be used during pregnancy or lactation, unless considered essential.
4.7 Effects On Ability To Drive And Use Machines
May theoretically be extensively absorbed through the skin when applied over large areas and cause somnolence and mild disorientation.
4.8 Undesirable Effects
Skin sensitisation has been reported on rare occasions.
4.9 Overdose
A 25g tube of Anthisan Cream contains 500mg mepyramine maleate. If accidentally ingested this dose would constitute a dangerous overdose in young children.
The chief symptom of overdosage is unconsciousness and there may be convulsions in the intervening periods. 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 against pneumonia.
