Why Do You Draw up Regular Insulin First

The rapid- or short-acting insulin (clear) is drawn up first to prevent the intermediate-acting insulin (cloudy) from getting into the rapid- or short-acting insulin bottle and affecting the onset, peak, and duration.

Do you draw regular insulin first?

When you mix regular insulin with another type of insulin, always draw the regular insulin into the syringe first. When you mix two types of insulins other than regular insulin, it does not matter in what order you draw them into the syringe.

Which insulin draws first cloudy or clear?

For example, if 10 units of insulin will be given, draw back 10 units of air. Insert the needle into the insulin bottle and depress the plunger, injecting the air into the bottle. If clear and cloudy insulin are used, inject air into the cloudy insulin first, followed by the clear insulin.
