Is it safe to use childrens benedryl for sleep aid if you have anxiety.

Yes, but...: Yes, but it is likely too weak to have any benefit. Why not speak with your doctor about solutions that would be more effective.

Yes & no: It is the main component (or only component) of most over the counter sleep aids. It can be of benefit to some, but it is in & out of your system in about 4 hours, which may not help you if anxiety is your issue. It has also been shown to lessen the amount of deep restorative sleep achieved.
