Among them, the maximum dose is before breakfast, followed by before dinner, and a smaller dose before lunch. The method is to inject. If an additional injection is needed before going to bed, the dose at this time is the smallest; patients with type 2 diabetes can also start with one or two injections of premixed insulin preparations per day. If the patient mainly suffers from poor fasting blood sugar, this injection preparation can be injected before dinner or before going to bed; if the patient mainly suffers from poor blood sugar two hours after breakfast, the insulin injection can be given on an empty stomach in the morning.
