Specializes in Allergy and Immunology

Drowsiness: Most likely will be drowsy. There can be respiratory suppression, at which point he would need to been evaluated in an emergency center. However, call poison control in your area to see if they have any other suggestions. Otherwise effects will wear off over time.
