You shouldn't change your own medicine, because each type of insulin has different action intensity and time.
The prescription of Novozymes prescribed by the doctor, three times a day, is determined according to the patient's blood sugar after and before each meal, and tries to imitate physiological insulin secretion.
If you switch to Novozymes 30, you have to be hospitalized, do blood sugar monitoring, and then adjust the dose according to blood sugar every day. It may not achieve the current therapeutic effect.
So for the sake of safety, it is recommended not to change the medicine casually!
