I understand your concern.
You're right that this drug contains Diphenhydramine
, the active agent in Benadryl. While this is not addicting, we do run the risk of your son developing tolerance. This means that with time higher doses would be required to produce the same effects. Also, if we start giving higher doses , and then stop, he might have severe withdrawal symptoms
. There are other side effects like a dry mouth and nose; constipation
but these are generally not very serious.
But it is intriguing that your young son has such a condition. He does need a basic psychiatric evaluation to rule out other causes of sleep issues (like anxiety or depression
Apart from that, I hope he has been taught about basic sleep hygiene
measures which can make a substantial difference to the quality of sleep.
I hope I have addressed your concern
