Types of Diabetes Medicines

Diabetes medicines come in several forms.

Insulin

If your body no longer makes enough insulin, you'll need to take it. Insulin is used for all types of diabetes. Your doctor can help you decide which way of taking insulin is best for you.

Taking injections. You'll give yourself shots using a needle and syringe. The syringe is a hollow tube with a plunger. You will put your dose of insulin into the tube. Some people use an insulin pen, which looks like a pen but has a needle for its point.

Using an insulin pump. An insulin pump is a small machine about the size of a cell phone, worn outside of your body on a belt or in a pocket or pouch. The pump connects to a small plastic tube and a very small needle. The needle is inserted under the skin and stays in for several days. Insulin is pumped from the machine through the tube into your body.

Using an insulin jet injector. The jet injector, which looks like a large pen, sends a fine spray of insulin through the skin with high-pressure air instead of a needle.

What does insulin do?

Insulin helps keep blood glucose levels on target by moving glucose from the blood into your body's cells. Your cells then use glucose for energy. In people who don't have diabetes, the body makes the right amount of insulin on its own. But when you have diabetes, you and your doctor must decide how much insulin you need throughout the day and night.

What are the possible side effects of insulin?

Possible side effects include

• low blood glucose (for more information, see Insert N)
• weight gain

How and when should I take my insulin?

Your plan for taking insulin will depend on your daily routine and your type of insulin. Some people with diabetes who use insulin need to take it two, three, or four times a day to reach their blood glucose targets. Others can take a single shot. Your doctor or diabetes educator will help you learn how and when to give yourself insulin.

Types of Insulin

Each type of insulin works at a different speed. For example, rapid-acting insulin starts to work right after you take it. Long-acting insulin works for many hours. Most people need two or more types of insulin to reach their blood glucose targets.

Look at the list of types of insulin on Insert C. Check off the names of the kinds of insulin you take. Then print and write the names of your insulins under My Insulins in the chart on Insert A.

Diabetes Pills

Along with meal planning and physical activity, diabetes pills help people with type 2 diabetes or gestational diabetes keep their blood glucose levels on target. Several kinds of pills are available. Each works in a different way. Many people take two or three kinds of pills. Some people take combination pills. Combination pills contain two kinds of diabetes medicine in one tablet. Some people take pills and insulin.

Your doctor may ask you to try one kind of pill. If it doesn't help you reach your blood glucose targets, your doctor may ask you to

• take more of the same pill
• add another kind of pill
• change to another type of pill
• start taking insulin
• start taking another injected medicine

If your doctor suggests that you take insulin or another injected medicine, it doesn't mean your diabetes is getting worse. Instead, it means you need insulin or another type of medicine to reach your blood glucose targets. Everyone is different. What works best for you depends on your usual daily routine, eating habits, and activities, and your other health conditions.

For information about the different kinds of pills and what they do, see the inserts. You'll see the brand name and the generic name-the scientific name-for each medicine. Find your diabetes pills and check off the names. Then print and write the names of your diabetes pills under My Pills and Injected Medicines in the chart on Insert A.

Injections Other Than Insulin

In addition to insulin, two other types of injected medicines are now available. Both work with insulin-either the body's own or injected-to help keep your blood glucose from going too high after you eat. Neither is a substitute for insulin.

See the cards in the pocket of this booklet for more information about these injected medicines. Check off the kinds you take. Then write the names of your injected medicines under My Pills and Injected Medicines in the chart on Insert A.

What do I need to know about side effects of medicines?

A side effect is an unwanted problem caused by a medicine. For example, some diabetes medicines can cause nausea or an upset stomach when you first start taking them. Before you start a new medicine, ask your doctor about possible side effects and how you can avoid them. If the side effects of your medicine bother you, tell your doctor.
