I wouldn't give medication unless the patient had signs & symptoms of an allergic reaction such as coughing, cramps, hives, itching, shortness of breath, tightness in the chest, swelling of the face, tongue or throat, nausea, vomiting or wheezing.
I usually give Albuterol 2.5-5.0 mg via HHN PRN, Benadryl 25-50 mg IM/IV, Tagament 300 mg IV, Solu Medrol 125 mg IV.
