My friend has a food allergy reaction. we are unable to access benadryl (diphenhydramine) (in saudi arabia). what action can we take? how much zyrtec can she take?

Look for: diphenhydramine which is the generic of Benadryl. They should know what that is/have it there. If you try Zyrtec, (cetirizine) take 10mg daily. Best of luck!

2/day: If she has Rash from food allergy, she can take 10 mg of Zyrtec (cetirizine) twice daily. If she has GI upset from food then she should avoid eating any solid food and drink plenty of liquid with electrolytes and stay hydrated. If she is having Respiratory distress, she need to seek the medical advise right away. Hope she feels better soon.

The recommended dose: Take 10mg daily as is the recommended dose. There are several other anti-histamines other than benadryl (diphenhydramine) that could be prescribed to her if the allergy is severe. Certainly avoid the foods first and foremost.
