What are the side effects of Novolog Flexpen?

The most common side effects of Novolog Flexpen are a rash, or thickening or pitting of the skin at the injection site. Novolog Flexpen uses a fast-acting form of insulin that can cause unsafe drops in blood sugar levels if not taken with food. If you experience low blood sugar, or hypoglycemia, while using Novolog Flexpen, you might develop these side effects:
•Changes in mood or behavior
•Tingling or numbness of the mouth
•Clumsy movements
•Loss of consciousness

Your doctor will give you specific instructions to follow if you develop hypoglycemia, such as eating a sugary food or beverage. Make sure that your family, friends, and others around you know that you are diabetic and should receive medical care if you become confused, lose consciousness, or seizures.

Other serious side effects of Novolog Flexpen include:
•Rapid heartbeat
•Full body itching or rash
•Shortness of breath
•Blurred vision

Seek medical help if you experience any of these symptoms while taking Novolog Flexpen, as they may be signs of allergic reaction.
