Managing Injection-Site Reactions (ISRs)

A number of nursing interventions help to limit the occurrence of injection-site reactions. Here are some suggestions for improving subcutaneous injections:

  • Use the proper injection technique as instructed by a nurse or physician
  • Apply ice to area before and after injection
  • Gently massage area after injection for at least two minutes; this helps disperse medicine and reduce irritation
  • Inject only into healthy tissue
  • Wait at least seven days before injecting in the same spot 
  • Check the site for redness, tenderness, or swelling two hours after injection.
  • Rotate injection sites and select subcutaneous sites that are preferred or are most comfortable
  • Avoid over-exposure to sunlight or ultraviolet rays
  • Use an analgesic as required (although you should check the most appropriate analgesic regimen with a doctor or nurse)
  • Where possible and when available, some people may wish to consider using an autoinjector to increase convenience, comfort and compliance
