Insulin Aspart, Recombinant (Subcutaneous)


Insulin Aspart is a form of insulin that is fast-acting. Insulin, in general, is one of many different hormones which help your body to turn food into energy. This process works by turning the sugar (glucose) in your blood into fast energy. A secondary function insulin has is helping us to store energy for future use.

However, if you suffer from diabetes mellitus, then your body is unable to create enough insulin, or simply does not use it properly. You must, therefore, take extra insulin in order to properly regulate blood sugar levels and maintain proper health. Having too much sugar in your blood can be very harmful to your health. You should generally take Insulin Aspart with a longer-lasting insulin as well.

Be aware, you can only obtain Insulin Aspart if you have a prescription from your doctor.
