Is blood return during an IM injection life-threatening?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I injected Kenacort into the muscle and when I made the return there was some blood. I did not notice that and I finished the injection. Is there a danger to the life of the patient?

Hello,

Welcome to icliniq.com.

I understand your concern.

Usually, we do not inject when during the return there is blood. However, we often recommend the patient:

  1. Not to use the injected muscle or leg for a few days.
  2. Apply cold compresses locally to avoid edema or hematoma.
  3. Look for signs of infection. Sometimes, an infection might occur and that site becomes painful, a lump might appear.

If you need to inject another vial, please report what you experienced the last time to your primary doctor, so can advise stopping giving the injection until we are totally sure nothing has happened on that muscle.
