Children's liquid benadryl and the fast melt tabs have 12.5 mg. per teaspoon/tablet. The adult pills come in 25 and 50 mg. The only side effect I've seen is drowsiness. Also, the information on the cream and spray say do not use it on a large area and they also warn not to use it orally and topically at the same time (I'm assuming to prevent overdose). |
