why do we mix insulin

by Rick Quitzon Published 2 years ago Updated 2 years ago

A person may find that mixing insulin is beneficial to them if they:

have regular mealtimes
want to be able to adjust the levels of the different insulins they receive as required
prefer only to take two injections per day

Using two types of insulin can help you keep your blood sugar levels in your target range. When you mix two insulins in one syringe, one type of insulin is always clear and short or rapid-acting, while the other type is cloudy and long-acting.

Insert the needle into the NPH (cloudy) insulin bottle and push the plunger in. This will force the air from the syringe into the bottle. Do NOT draw any NPH (cloudy) insulin into the syringe.

Insulin Administration

Insulin is necessary for normal carbohydrate, protein, and fat metabolism. People with type 1 diabetes mellitus do not produce enough of this hormone to sustain life and therefore depend on exogenous insulin for survival. In contrast, individuals with type 2 diabetes are not dependent on exogenous insulin for survival.

First thing in the morning I am also going to eat breakfast, which will require an injection of short-acting insulin. Do I take two shots?

What are the different types of insulin?

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. Rapid Acting Insulins 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 that begin to work 10 minutes after injection and peak at 1 hour after injection, lasting for 3-4 hours in the body. However, 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 and are used as “bolus” insulins to be given 15 minutes before a meal. Note: Check blood sugar level before giving Humalog or Novalog. Your doctor or diabetes educator will instruct you in determini Continue reading >>

How does insulin lispro work?

What is insulin lispro, and how can it help control my blood sugar levels? Insulin lispro (brand name: Humalog) is the newest type of insulin on the market. It's a fast-acting insulin that starts working sooner than other insulins. It also reaches peak activity faster and goes away sooner. Insulin lispro helps keep your blood sugar levels from going too high after you eat. Studies show that insulin lispro may do this better than regular insulin. In fact, insulin lispro may replace regular insulin for many patients with diabetes mellitus. The medicines your doctor has prescribed are very important in keeping your diabetes under control. To keep your blood sugar level steady, your doctor will probably prescribe either a longer-acting insulin or another drug for you to take each day in addition to the insulin lispro. When and how do I take insulin lispro? Insulin lispro should be injected under the skin within 15 minutes before you eat. Your doctor will tell you how much insulin lispro to inject. Remember, you must eat 15 minutes after you take this insulin shot. Insulin lispro is a little easier to take than regular insulin. If you've been using regular insulin, you've had to inject the insulin and then wait 30 to 45 minutes before eating. Many people find it hard to time regular insulin injections and mealtimes. Sometimes they end up eating too early or too late. Then they don't get the best blood sugar control. Since insulin lispro is taken so close to meals, it may help you get the best possible blood sugar control. Can I mix insulin lispro with other insulins? It's best that you mix insulin lispro only with Humulin U or Humulin N, which are brand names for certain longer-acting insulins. Insulin lispro should always be drawn into the syringe first. This will keep the Continue reading >>

How to mix clear insulin?

Push the plunger down to inject air into the CLOUDY bottle. Withdraw the empty syringe from the bottle. Set the bottle aside. Pull the plunger down to the correct unit mark for the CLEAR insulin dose as ordered. Insert the needle into the CLEAR bottle. Push the plunger down to inject air into the CLEAR bottle. Leave the needle in the bottle. Turn the bottle upside down with the needle in it. Pull the plunger down to the correct unit mark for the CLEAR insulin dose. Look for air bubbles in the syringe. If you see air bubbles in the syringe, push the insulin back into the bottle, and repeat steps 17 and 18. Pull the bottle away from the needle, and set aside the CLEAR bottle. Pick up the CLOUDY bottle of insulin. Turn the CLOUDY bottle upside down and push the needle into the bottle. Be very careful not to move the plunger. Pull the plunger down and withdraw the correct number of units for the CLOUDY insulin. The plunger should now be on the unit mark showing the total units of both the CLEAR and CLOUDY types of insulin. For example, 6 units of CLEAR insulin are already in the syringe. Add 14 units of CLOUDY insulin for a total of 20 units in the syringe. Pull the bottle away from the needle. Set both bottles on the table. Look for air bubbles in the syringe. If you see air bubbles, discard the dose and begin again. Set the syringe down. Do not let the needle touch anything. Pinch or spread the skin a Continue reading >>
