Cetirizine (Zyrtec) is a second-generation antihistamine that's generally preferred for treating mild food allergy symptoms like hives because it causes fewer side effects than older options like diphenhydramine (Benadryl).
For dosing frequency, cetirizine is typically taken once daily. It's approved for children ages 2 and older, and starts working in about 15 to 30 minutes.
A few important things to keep in mind:
- Antihistamines are only appropriate for mild symptoms like itchy skin or a few hives
- They are not a substitute for epinephrine if serious symptoms appear
- If hives are accompanied by trouble breathing, swelling, or other severe symptoms, use an epinephrine auto-injector immediately and seek emergency care
Always check with a doctor or pharmacist for the right dose, especially for children, as it can vary by age and weight.
