Mixed insulin

Mixed insulin is cloudy in appearance. It is a combination of either a rapid onset-fast acting or a short acting insulin and intermediate acting insulin. Advantage of it is that, two types of insulin can be given in one injection. When it shows 30/70 then it means 30% of short acting is mixed with 70%of intermediate acting insulin.
Note: - Roll or shake well the vial of insulin in order to mixed them evenly.
