What are the risks of taking Novolin?

A serious risk of taking Novolin, a form of insulin for people with diabetes, is hypoglycemia, which is low blood sugar. If after using Novolin you feel dizzy, faint or weak, or you start sweating, your blood sugar may have dropped too low. This can be confirmed by testing with a glucose meter. Talk to your doctor about what you should do if this occurs. You'll probably be advised to eat something with sugar, such as some hard candies, or to drink half a glass of juice. Get medical help if you suspect your symptoms are severe or they don't go away after you eat sugar.

Other side effects can include signs of an allergic reaction, such as a rash, shortness of breath, blurred vision, wheezing, dizziness, fast heartbeat and trouble breathing or swallowing. If this happens, get emergency medical help right away. You may also experience redness, swelling or itching where the medicine was injected. Let your doctor know if this occurs.
