Warnings & precautions in children

Young children are in general a lot more sensitive to the toxic effects of antihistamines than adults. With classical antihistamines, reversible dyskinesia and paradoxical excitement (restlessness, sleeplessness, tremors, euphoria, nervousness and an increased tendency to convulsions) can also occur at therapeutic doses. Ataxia, restlessness, hallucinations, increased body temperature, cramps followed by coma, possibly resulting in the death are the (parasympathetic) symptoms of intoxication. Use of sedating antihistamines in children aged less than 2 years is contraindicated, given that the use of promethazine and deptropine has been linked to sudden infant death syndrome (SIDS). Caution is also needed when administering it to children with sleep apnoea in their previous history, when SIDS has occurred in the family, in children who wake up less easily and in children who are ill or dehydrated. Although there have been no properly set up and controlled studies in children, it is probable that ‘non-sedating’ antihistamines do not produce central side effects, given that the extent to which they pass the blood-CSF barrier is small to zero.
