What are the side effects of NovoLog?

The primary side effect of NovoLog (insulin aspart) is low blood sugar, or hypoglycemia. Signs of hypoglycemia include dizziness, irritability or mood swings, cold sweats, shakiness, extreme hunger, blurred vision, confusion, seizures, unconsciousness, loss of coordination, and difficulty speaking.

You may also experience skin irritation at the injection site, including redness or thinning or thickening of skin tissue, but this is a minor side effect.

See your doctor immediately if you experience unusual muscle pain. As with any food or drug, you may experience an allergic reaction from NovoLog, which includes rash, itching, hives, swelling of your throat or mouth, and trouble breathing. If you have signs of an allergic reaction, get emergency medical help right away.
