1. What is Byetta and what is it used for
Byetta contains the active substance exenatide. It is an injectable medicine used to improve blood sugar control in adults with type 2 diabetes mellitus (non-insulin dependent).
Byetta is used with other diabetes medicines, such as metformin, sulfonylureas, thiazolidinediones, and basal or long-acting insulin. Your doctor has prescribed Byetta as an additional medicine to help control your blood sugar. Continue with your exercise and diet plan.
You have diabetes because your body does not produce enough insulin to control your blood sugar levels or because your body cannot use insulin properly. The medicine in Byetta helps your body increase insulin production when your blood sugar is high.
2. What you need to know before you use Byetta
Do not use Byetta
- If you are allergic to exenatide or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor, pharmacist, or diabetes nurse before starting Byetta about the following:
- Using this medicine in combination with a sulfonylurea, as you may have low blood sugar (hypoglycemia). Ask your doctor, pharmacist, or diabetes nurse if you are not sure if any of your other medicines contain a sulfonylurea.
- If you have type 1 diabetes or diabetic ketoacidosis (a dangerous condition that can occur in diabetes), as you should not use this medicine.
- How to inject this medicine. It should be injected under the skin and not into a vein or muscle.
- If you have severe problems with stomach emptying or digestion, as the use of this medicine is not recommended. The active ingredient in this medicine slows down stomach emptying, so food passes more slowly through your stomach.
- If you have ever had pancreatitis (inflammation of the pancreas) (see section 4).
- Tell your doctor if you lose weight too quickly (more than 1.5 kg per week), as it may cause problems such as gallstones.
- If you have severe kidney disease or are on dialysis, as the use of this medicine is not recommended. There is limited experience with this medicine in patients with kidney problems.
Byetta is not insulin, so it should not be used as a substitute for insulin.
Children and adolescents
Do not give this medicine to children and adolescents under 18 years of age, as there is no experience with this medicine in this age group.
Using Byetta with other medicines
Tell your doctor or pharmacist if you are using or have recently used or might use any other medicines, especially:
- Medicines used to treat type 2 diabetes that work like Byetta (e.g., liraglutide and extended-release exenatide), as it is not recommended to use these medicines with Byetta.
- Blood-thinning medicines (anticoagulants), such as warfarin, as you may need extra monitoring of changes in your INR (a measure of blood clotting) when starting treatment with this medicine.
Ask your doctor if you need to change the time you take any tablets you are using, as this medicine slows down stomach emptying and may affect medicines that need to pass through the stomach quickly, such as:
- Enteric-coated tablets or capsules (e.g., medicines that reduce stomach acid) that should not stay in the stomach for too long may need to be taken 1 hour before or 4 hours after injecting this medicine.
- Some antibiotics may need to be taken 1 hour before injecting Byetta.
- For tablets that need to be taken with food, the best option may be to take them with a meal when you are not injecting this medicine.
Using Byetta with food
Use this medicine at any time within 60 minutes (1 hour) beforeyour meal. (See section 3 "How to use Byetta"). Do not usethis medicine aftera meal.
Pregnancy and breastfeeding
It is not known if this medicine can have harmful effects on the fetus. If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine, as it should not be used during pregnancy.
It is not known if exenatide passes into breast milk. This medicine should not be used if you are breastfeeding.
Driving and using machines
If you use this medicine in combination with a sulfonylurea or insulin, you may have low blood sugar (hypoglycemia). Hypoglycemia can reduce your ability to concentrate. Please be aware of this possible problem in situations where you may put yourself and others at risk (e.g., driving a car or using machines).
Byetta contains metacresol.
Metacresol may cause allergic reactions.
Byetta contains sodium.
This medicine contains less than 1 mmol of sodium (23 mg) per dose; this is essentially "sodium-free".
3. How to use Byetta
Follow the instructions for administering this medicine exactly as told by your doctor, pharmacist, or diabetes nurse. If you are unsure, consult your doctor, pharmacist, or diabetes nurse again.
There are two concentrations of Byetta available: Byetta 5 micrograms and Byetta 10 micrograms. Your doctor may tell you to start treatment using Byetta 5 micrograms twice a day. After using Byetta 5 micrograms twice a day for 30 days, your doctor may increase your dose to Byetta 10 micrograms twice a day.
If you are over 70 years old or have kidney problems, you may take longer than 30 days to tolerate the 5 microgram dose of Byetta, so your doctor may not increase your dose.
An injection from your pre-filled pen will give you your dose. Do not change your dose unless your doctor tells you to.
You should inject this medicine at any time within 60 minutes (1 hour) beforeyour breakfast and dinner, or before your two main meals of the day, which should be at least 6 hours apart. Do not usethis medicine aftermeals.
You should inject this medicine under the skin (subcutaneously) in the upper leg (thigh), stomach area (abdomen), or upper arm. If you are using Byetta and insulin, you should inject them separately.
To establish your dose of Byetta, you do notneed to check your blood sugar levels daily. However, if you are also using a sulfonylurea or insulin, your doctor may tell you to check your blood sugar levels to adjust the dose of sulfonylurea or insulin. If you are receiving insulin, your doctor will tell you how to reduce your insulin dose and recommend that you monitor your blood sugar levels more frequently to avoid high blood sugar (hyperglycemia) and diabetic ketoacidosis (a complication of diabetes that occurs when the body cannot break down glucose because there is not enough insulin).
In the User Manual for the Pen that comes with this leaflet, you can find instructions on how to use the Byetta pen.
Your doctor or nurse should teach you how to inject Byetta before you use it for the first time.
Becton, Dickinson and Company needles are suitable for use with the Byetta pen. The needles for injection are not included.
Use a new needle for each injection and discard it after each use. This medicine is for you; never share the Byetta pen with others.
If you use more Byetta than you should
If you use more of this medicine than you should, talk to your doctor or go to a hospital immediately. Using too much of this medicine can cause nausea, vomiting, dizziness, or symptoms of low blood sugar (see section 4).
If you forget to use Byetta
If you forget a dose of this medicine, skip that dose and give your next dose when it is due. Do notgive a double dose or increase the amount of your next dose to make up for the forgotten dose.
If you stop using Byetta
If you think you need to stop using this medicine, consult your doctor first. If you stop using this medicine, it may affect your blood sugar levels.
If you have any other questions about using this medicine, ask your doctor, pharmacist, or diabetes nurse.
