Suggest Treatment For Side Effects Of Reglan

My 13 yr old daughter took reglan for 2 days for nausea.she has serious side effects including uncontrollable movement of her arms and hands, rash, weakness in her arms and legs. We took her to the ER and they gave her benadryl. She has been in the benadryl for 12 days. She is still having weakness in her arms and legs. Is this normal?
