Injection site reactions

Injection site reactions include redness, itchingpain or swelling at the injection site. They mostly occur 1 to 2 days after an injection and go away within 3 to 5 days.

  • Change the injection site each time you inject (e.g. rotate from one leg to another leg).
  • Apply a cold compress to the injection site.
  • Antihistamine tablets can help.
  • If you continue to experience problems please contact us and we will be able to provide you further advice.
