Diabetes Types of Insulin – PostCare Recovery Patient Education HD

Insulin is the hormone normally made in the
pancreas that stimulates the flow of sugar – glucose – from the blood into the cells
of the body. Glucose provides the cells with the energy they need to function. There are two main groups of insulins used
in the treatment of diabetes: human insulins and analog insulins, made by recombinant DNA
technology. The concentration of most insulins available
in the United States is 100 units per milliliter. A milliliter is equal to a cubic centimeter.
All insulin syringes are graduated to match this insulin concentration. There are four categories of insulins depending
on how quickly they start to work in the body after injection: *Very rapid acting insulin
*Regular, or Rapid acting insulins *Intermediate acting insulins
*Long acting insulin. *In addition, some insulins are marketed mixed
together in different proportions to provide both rapid and long acting effects. Certain
insulins can also be mixed together in the same syringe immediately prior to injection. A very rapid acting form of insulin called
Lispro insulin is marketed under the trade name of Humalog.
A second form of very rapid acting insulin is called Aspart and is marketed under the
trade name Novolog. Humalog and Novolog are: *clear liquids.
*They begin to work 10 minutes after injection, *peak at 1 hour after injection,
*and last 3-4 hours in the body. *Most patients also need a longer-acting insulin
to maintain good control of their blood sugar. Humalog and Novolog can be mixed with NPH
insulin. *Humalog and Novolog are used as “bolus” insulins
to be given 15 minutes before a meal. Most patients also need a longer-acting insulin
to maintain good control of their blood sugar. Humalog and Novolog can be mixed with NPH
insulin. *Check your blood sugar level before giving
Humalog or Novalog. Your doctor or diabetes educator will instruct
you in determining your insulin dose based on your blood sugar reading and anticipated
meals and exercise. Always check the bottle before drawing up
the insulin. If the solution is cloudy, discard the bottle. *If you are mixing Humalog or Novalog with
a longer-acting insulin, always draw up the Humalog or Novalog first to maintain the purity
and clarity of the Humalog and Novalog solutions. Another solution of insulin that acts rapidly
is called “Regular” or “R” insulin. This insulin does not act as quickly as Humalog or Novalog. Regular insulin is: *a clear, colorless liquid.
*It begins to work 30 minutes after injection, *peaks at 3-5 hours
*and lasts 6-10 hours in the body. Regular insulin is: *usually given 30 minutes before a meal.
*It can also be mixed with in the same syringe with longer acting NPH insulin or given separately
immediately after each other. *Glargine cannot be mixed with it. Regular insulin is: *the most stable of all the different types
of insulin, *but unopened regular insulin is best refrigerated.
*Always check the bottle before drawing up the insulin.
*If the solution is cloudy, discard the bottle. *If you are mixing Regular with a longer-acting
insulin, always draw up the Regular insulin first to maintain the purity and clarity of
the Regular solution. Examples of intermediate acting insulins are
NPH. Intermediate acting insulins are: *cloudy suspensions of crystalline insulin.
*They need to be gently rotated between the hands before being used.
*They begin to work 1 hour after injection, *peak at 6-12 hours after injection
*and last 20-24 hours in the body. The intermediate insulins are: *often given before breakfast.
*They may also be given at bedtime, depending on your blood glucose reading.
*They can be mixed in the same syringe with Regular, Lispro and Aspart insulins. Ultralente is a long-acting insulin. Ultralente is: *a cloudy suspension.
*It begins to work 2-8 hours after injection, *peaks at about 12 hours
*and lasts around 18-24 hours in the body. Ultralente insulin is: *often given before breakfast.
*It may also be given before dinner in the evenings or at bedtime, on your doctor’s instruction.
*It can be mixed in the same syringe with regular insulin.
*When unopened, it is best stored in the refrigerator. Another long-acting insulin is called Glargine
insulin. It is an insulin analog manufactured by recombinant DNA technology. Unlike other long-acting insulins, Glargine
insulin is: *a clear solution of insulin.
*It begins to work around 1 hour after injection. *There is no pronounced peak.
*Small amounts of Glargine insulin are released slowly to provide a relatively constant amount
of insulin in the body over 24 hours. *Glargine insulin cannot be mixed with any
other insulin. *A change to Glargine from NPH insulins s
hould be done under the close supervision of your medical team. There are three stable, premixed formulations
of insulin. *One contains 70% of NPH insulin and 30% of
Regular insulin. *Another formulation contains 50% of NPH and
30% of Regular insulin. *The third contains 75% of NPH and 25% of
Humalog. These mixtures: *begin to work around one half hour after
injection, *peak in 2-8 hours
*and last up to 24 hours in the body. *As these premixed insulins contain rapid
or very rapid acting insulin, they should be taken before meals as directed by your
medical team. *With your doctor’s instructions, several
combinations of two different kinds of insulin can be mixed together in the same syringe
and given as one injection. *Once mixed, the combined injection must be
given immediately or the effect of the regular component of the injection will be diminished.
*The rapid-acting insulins, Lispro, Aspart and Regular, can be mixed with the longer
acting NPH insulin. *Glargine cannot be mixed with any other insulin.
