Source links checked June 16, 2026.

Details to record

  • Injection date and time
  • Injection site
  • Size, redness, swelling, itching, warmth, or pain
  • Whether symptoms are spreading or improving
  • Any fever, hives, breathing symptoms, or swelling elsewhere

Ask before changing technique

Your medication instructions may include specific directions for storage, preparation, injection sites, and disposal.

If reactions recur, ask a pharmacist or clinician to review your technique and medication instructions rather than guessing.

When symptoms may be urgent

A local reaction is different from signs of a serious allergic reaction. Do not wait on severe or whole-body symptoms.
