Exenatide and liraglutide are a type of medicine called incretin mimetics used to treat people who have
type 2 diabetes and who have not been able to control
their blood sugar levels with oral medicines. This medicine is given as a shot.
This medicine is also known as a glucagon-like peptide 1 (GLP-1) receptor agonist, or GLP-1 agonist.
Incretin is a natural hormone that your body makes. It tells your body to release insulin after you eat. Insulin lowers blood sugar.
Incretin mimetics act like (mimic) the incretins in your body that lower blood sugar after eating. Incretin mimetics:
These medicines help to keep blood sugar in a target range without causing low blood sugar or weight gain, unless they are taken in combination with medicines that do. Some people feel less hungry and lose weight while taking these medicines.
Type 2 diabetes is a disease that can get worse over time, so medicines may need to change.
Diabetes medicines work best for people who are being active and eating healthy foods. Studies have suggested that incretin mimetics lower hemoglobin A1c by 0.5% to 1%.footnote 1

effects. (Drug Reference is not available in all systems.)
Nausea is usually worse during the first few weeks of
treatment and gets better over time. Some people have fewer problems with nausea when they eat slowly, drink more water, and eat smaller meals with less fat.
When the medicine is given in an extended-release formula, small lumps at the injection site may appear. These absorb into the body as the medicine is released.
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
