Uses for NovoLOG Mix 70/30 FlexPen
Insulin aspart protamine and insulin aspart is a combination of a fast-acting insulin and an intermediate-acting type of human insulin. Insulin is used by people with diabetes to help keep blood sugar levels under control. When you have diabetes mellitus, your body cannot make enough or does not use insulin properly. So, you must take additional insulin to regulate your blood sugar and keep your body healthy. This is very important as too much sugar in your blood can be harmful to your health.
This medicine is available only with your doctor's prescription.
