BYETTA and Lantus (insulin glargine)

What kind of insulin can BYETTA injection be taken with?

BYETTA is approved for use with Lantus (insulin glargine), which is a long-acting insulin, but should not be taken with short- and/or rapid-acting insulin. BYETTA is not insulin and should not be taken instead of insulin.

Will adding BYETTA to Lantus help better manage my type 2 diabetes?

BYETTA can help lower your A1C level. In a clinical study, BYETTA helped 57% of patients achieve an A1C level of less than 7% compared with 30% of those taking Lantus alone.

Will adding BYETTA to Lantus help me lose some weight?

Although BYETTA is not a weight-loss product, it may reduce the amount of food you eat. On average, patients who used the 10-microgram dose of BYETTA, in combination with certain diabetes pills or Lantus, lost 4 pounds over 30 weeks. Taken on its own, Lantus has been shown to increase weight by 2 pounds over 30 weeks.

What are the most common side effects of taking BYETTA with Lantus?

The most common side effect of taking BYETTA is mild to moderate nausea, which decreases over time for most people. The risk of getting low blood sugar is higher if you take BYETTA with another medicine that can cause low blood sugar, such as certain diabetes pills or insulin.

In clinical studies, fewer than half the patients taking BYETTA and Lantus experienced nausea. Some common side effects that occurred more often in patients taking BYETTA with Lantus than in patients taking Lantus alone include nausea, vomiting, diarrhea, headache, constipation, and weakness.

Can I stop taking other diabetes medications when I start taking BYETTA and Lantus?

Consult with your doctor before you stop taking any medications. Your doctor will most likely add BYETTA to your treatment plan for type 2 diabetes while keeping you on any pills you are currently taking for diabetes in addition to Lantus. Of course, the decision is up to you and your doctor.

Will adding BYETTA to Lantus interact with any other medicines I am taking?

It’s important to tell your doctor about all the medicines you are taking. BYETTA can slow down how quickly some medicines taken by mouth get into your bloodstream.

Will my doctor need to change my dose of Lantus when I start taking BYETTA?

Ask your doctor. If your A1C level is less than 8 when your doctor prescribes BYETTA, your doctor may reduce your dose of Lantus. An A1C blood test is used to determine your blood sugar control by providing a 3-month average of your blood sugar levels.

Is BYETTA easy to use?

BYETTA comes in a simple, prefilled pen, so it can conveniently fit into your life. You don’t have to measure out each dose or adjust your dose based on the size of a meal or different levels of physical activity. Instructions for using the BYETTA Pen can be found here.

Do I need to change the time I take Lantus when I add BYETTA?

Talk to your doctor to see if any changes are necessary.
