Exenatide is used with a proper diet and exercise program to control high blood sugar. It is used by people with type 2 diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke.
Exenatide is a diabetes drug that is similar to a natural hormone in your body (incretin). It works by increasing insulin release (especially after a meal) and decreasing the amount of sugar your liver makes. It also slows down food digestion in your stomach, decreases the amount of sugar absorbed from food, and may help decrease your appetite.
How To Use
Read the Medication Guide and the Pen User Manual provided by your pharmacist before you start using exenatide and each time you get a refill. Learn all preparation and usage instructions. If you have any questions, ask your doctor or pharmacist.
Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Before injecting each dose, clean the injection site with rubbing alcohol. Change the injection site each time to lessen injury under the skin.
Inject this medication under the skin in the thigh, abdomen, or upper arm as directed by your doctor, usually twice a day. Injection should be done within 60 minutes before the morning and evening meals (or before the two main meals of the day, at least 6 hours apart). Exenatide should not be used after a meal since it will not work as well.
If you are also using insulin, give exenatide and insulin as separate injections. Do not mix them. You may inject these medications in the same area of the body, but the injection sites should not be next to each other.
Since exenatide slows down digestion of food/drugs in your stomach, certain medications (such as birth control pills, antibiotics taken by mouth) may not work as well if you take them at the same time. Take birth control pills or antibiotics at least 1 hour before using exenatide. If you must take these medications with food, take them with a meal or snack when you do not also take exenatide. Ask your doctor or pharmacist if you have any questions about when to take your medications.
The dosage is based on your medical condition and response to treatment. Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day. Carefully follow your diabetes management plan, including medications, diet, and exercise.
Check your blood sugar regularly as directed by your doctor. Keep track of the results, and share them with your doctor. Tell your doctor if your blood sugar measurements are often too high or too low. Your doctor may need to adjust your diabetes medication, exercise program, or diet.
Do not share your pen device with another person, even if the needle is changed. You may give other people a serious infection, or get a serious infection from them. Learn how to store and discard medical supplies safely.

Nausea, vomiting, diarrhea, nervousness, or upset stomach may occur as your body adjusts to the medication. Nausea usually lessens as you continue to use exenatide. Other side effects include decreased appetite or weight loss. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Although exenatide by itself usually does not cause low blood sugar (hypoglycemia), low blood sugar may occur if this drug is prescribed with other diabetes medications. Talk with your doctor or pharmacist about all your diabetes medication(s).
Symptoms of low blood sugar include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, rapidly raise your blood sugar by eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor about the reaction right away. Low blood sugar is more likely if you drink large amounts of alcohol, do unusually heavy exercise, or do not consume enough calories from food. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Talk with your doctor or pharmacist about what to do if you miss a meal.
Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor right away. Your doctor may need to adjust your diabetes medication(s).
Tell your doctor right away if you have any serious side effects, including:
- signs of kidney problems (such as change in the amount of urine)
- yellowing of the eyes/skin
- easy bruising/bleeding
Exenatide has rarely caused a very serious (possibly fatal) disease of the pancreas (pancreatitis). Get medical help right away if you develop symptoms of pancreatitis, including:
- nausea/vomiting that doesn't stop
- severe stomach/abdominal pain
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:
- itching/swelling (especially of the face/tongue/throat)
- severe dizziness
- trouble breathing
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.

Beta-blocker medications (such as metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar falls too low (hypoglycemia). Other symptoms of low blood sugar, such as dizziness, hunger, or sweating, are unaffected by these drugs.
Many drugs can affect your blood sugar, making it harder to control. Before you start, stop, or change any medication, talk with your doctor or pharmacist about how the medication may affect your blood sugar.
