Frequently Asked Questions

When should I use the EpiPen?

Use it for any severe reaction: difficulty breathing, throat or face swelling, severe whole-body hives with other symptoms, or rapid pulse with dizziness. When in doubt, use it — the risks of not using it are greater than using it unnecessarily.

Can I give Benadryl instead of the EpiPen?

Never substitute Benadryl for the EpiPen during a severe reaction. Benadryl works too slowly for anaphylaxis. Use the EpiPen first, then Benadryl can be given as a follow-up.

Do we still need the ER if the EpiPen worked?

Yes, always. The EpiPen wears off in 15-20 minutes, and symptoms can return (biphasic reaction). Your child needs monitoring and potentially additional treatment.

How long should I watch for symptoms?

Most reactions occur within minutes to 2 hours. However, watch closely for at least 4-6 hours because biphasic reactions can happen. Seek immediate care if any symptoms return.

My child has never had an allergic reaction before — could this really be one?

Yes. First reactions can happen at any age, even to foods or substances they have had before. Take any concerning symptoms seriously. It is better to overreact than to wait.
