Novomix 30 Flexpen is a medication used in the management of diabetes. It is a combination of insulin aspart and insulin aspart protamine. Insulin aspart acts rapidly to reduce blood sugar levels after meals, while insulin aspart protamine has a longer duration of action to help maintain blood sugar control between meals. Novomix 30 Flexpen helps regulate blood glucose levels in patients with diabetes, reducing the risk of complications associated with uncontrolled diabetes. It is administered subcutaneously and should be used as prescribed by a healthcare provider.
