Can I Inject Insulin into Muscle?

Q: Is there any reason not to inject insulin directly into muscle?

A: There is really no medical evidence that intramuscular injections are harmful. They hurt more than subcutaneous injections and people need to use sterile syringes to prevent infection, but otherwise this type of injection can speed up insulin action considerably. In fact, absorption occurs twice as fast in most cases. This can be a useful tool for bringing high blood glucose levels down quickly or for avoiding blood sugar spikes when consuming high glycemic meals without a pre-bolus.
