Insights
Histamine H1 antagonists like oxatomide may trigger West syndrome in infants. Caution is advised when prescribing these medications to young children due to potential neurological risks.
Area of Science:
- Pediatric Neurology
- Pharmacology
- Dermatology
Background:
- West syndrome is a severe form of epilepsy in infants.
- Atopic dermatitis is a common inflammatory skin condition in infants.
- Histamine H1 antagonists are commonly used to treat allergic conditions.
Observation:
- A 4-month-old infant developed West syndrome 11 days after receiving oxatomide for atopic dermatitis.
- The infant's clinical presentation and the timing of the event were similar to previous cases involving ketotifen.
Findings:
- Oxatomide, a histamine H1 antagonist, is a potential trigger for West syndrome in susceptible infants.
- The mechanism may involve the disruption of the central histaminergic system, which plays a role in seizure control.
Implications:
- Clinicians should exercise caution when prescribing oxatomide and ketotifen to young infants.
- Further research is needed to understand the neurotoxic potential of histamine H1 antagonists in pediatric populations.
- Monitoring for seizure activity is crucial in infants treated with these medications.
Abstract:
We report a 4-month-old female infant who developed West syndrome eleven days after administration of a histamine H1 antagonist, oxatomide, for atopic dermatitis. It has been reported that some histamine H1 antagonists induce seizures in epileptic patients. The age, the interval between oxatomide administration, and the onset of West syndrome and its clinical course were similar to two previously reported 3-month-old infants with West syndrome associated with ketotifen administration. We should be cautious in using the histamine H1 antagonists, oxatomide and ketotifen, in young infants because such agents could potentially disturb the anticonvulsive central histaminergic system.
