i have gone through your query and can understand your concern. i suggest tablet allegra 180 mg (fexofenadine) twice daily for five days. one tablet is to be taken in the morning and one at night after meals. consult her doctor discuss with him or her and take the medicine with consent. try to maintain a gap of at least three hours between diabetic medicines and allegra. as such reactions are rare but still maintain the gap. give her steam inhalation four times a day. there is no need to give her cetirizine if you are giving allegra. for further information consult an internal medicine physician online --> <link>
