How Urgent Care Treats Mild Allergic Reaction

  • Identify likely trigger and refer to an allergist

What to Expect at Your Visit

A mild allergic reaction visit takes 30-60 minutes plus observation time. The provider may give antihistamines or steroids, watch you for 30-60 minutes to ensure symptoms don't worsen, and prescribe an EpiPen for future reactions. Cost: $100-$300 (more if epi or IV is needed).

  • Trouble breathing or wheezing (anaphylaxis — call 911 first)

  • Dizziness, fainting, or rapid heartbeat
  • Reaction to a known severe allergen (e.g. nuts, bee sting if severely allergic)

Frequently Asked

How do I know if my reaction needs urgent care vs. ER vs. 911?

If you have any breathing trouble, throat tightness, or swelling of the face/tongue — that's anaphylaxis, call 911 and use an EpiPen if you have one. If it's hives, itching, or mild swelling without breathing problems, urgent care is appropriate.

Can urgent care prescribe an EpiPen?

Yes. If you've had a moderate-to-severe allergic reaction, the provider can prescribe an epinephrine auto-injector (EpiPen, Auvi-Q) to keep on hand. They'll also teach you how to use it.
