In Treatment of Diabetes

Novorapid FlexPen is a modern, rapid-acting form of insulin that helps to control high blood glucose (sugar) levels. It replaces the insulin that is normally produced in the body. This helps the glucose get into your cells so your body can use it for energy. It begins to lower your blood glucose level within 10-20 minutes of injecting it and the effect can last for 3-5 hours. You will need to learn exactly how, where, and when to inject this medicine for it to be most effective.

Lowering blood glucose levels helps reduce the risk of getting any of the serious complications of diabetes such as kidney damage, eye damage, nerve problems, and loss of limbs. Taking this medicine regularly along with proper diet and exercise will help you live a normal, healthy life.
