About taking Bydureon BCise

Below you’ll find information about key dosage issues.

  • When to take: Bydureon BCise can be injected at any time of day. You should take your dose on the same day each week. If needed, you can change the day you take the dose. If you change the day, you should make sure there are always at least 3 days between doses.
  • If you miss a dose: If you miss a weekly dose, take it as soon as you remember, as long as your next dose isn’t due for at least 3 days. If your next dose is due within 3 days, skip your missed dose and take your next dose on your usual schedule. Never take two doses at the same time to catch up. This may cause serious side effects, such as severe hypoglycemia (low blood sugar).
  • Taking Bydureon BCise with food: Bydureon BCise can be injected with or without food.
  • Length of use: Bydureon BCise is meant to be used as a long-term treatment. If you and your doctor determine that Bydureon BCise is safe and effective for you, you’ll likely take it long term.
  • Length of time to work: Bydureon BCise begins to work right after you inject it. But when you’re first starting to take Bydureon BCise, its effects build up over several weeks. This means you won’t have the full effects of Bydureon BCise until about 10 weeks after your first injection. After this time, you’ll have a steady amount of Bydureon BCise in your body to help manage your blood sugar levels.

Overdose

Using more than the recommended dosage of Bydureon BCise can lead to serious side effects. Do not use more Bydureon BCise than your doctor recommends.

Is Bydureon BCise prescribed for weight loss?

Bydureon BCise is not approved for weight loss or weight management, but it’s possible that your doctor may prescribe it off-label for this use. Off-label use is when your doctor prescribes a drug for a different condition than the one it was approved for.

A side effect of Bydureon BCise is decreased appetite. As a result, many people with diabetes who use the drug lose weight. In clinical trials, people taking Bydureon BCise lost between about 1 kilogram (kg) and 2.7 kg (between about 2.2 pounds [lb] and about 6 lb) on average.
