Mixtard vials are for use with insulin syringes with the corresponding unit scale.
Mixtard is a dual-acting insulin. It is biphasic formulation containing fast-acting and long-acting insulin.
Mixtard will start to lower your blood sugar about half an hour after you take it, and the effect will last for approximately 24 hours.
Premixed insulin products are usually given once or twice daily when a rapid initial effect together with a more prolonged effect is desired.
