What is the most important information I should know about insulin glargine?
Never share an injection pen, even if you changed the needle.
What is insulin glargine?
Insulin glargine is a long-acting insulin that starts to work several hours after injection and keeps working evenly for 24 hours.
Insulin glargine is used to improve blood sugar control in people with diabetes mellitus.
Toujeo is for use in adults with type 1 or type 2 diabetes.
Basaglar, Lantus, and Semglee are for use in adults with type 1 or 2 diabetes and in children at least 6 years old with type 1 diabetes (not type 2).
For type 1 diabetes, insulin glargine is used together with a short-acting insulin given before meals.
Insulin glargine may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before using insulin glargine?
You should not use this medicine if you are allergic to insulin, or if you are having an episode of hypoglycemia (low blood sugar) or diabetic ketoacidosis (call your doctor for treatment).
Insulin glargine is not approved for use by anyone younger than 6 years old, and some brands are for use only in adults. Do not use this medicine to treat type 2 diabetes in a child of any age.
Tell your doctor if you have ever had:
- liver or kidney disease; or
- heart failure or other heart problems.
Tell your doctor if you also take pioglitazone or rosiglitazone (sometimes contained in combinations with glimepiride or metformin). Taking certain oral diabetes medicines while you are using insulin may increase your risk of serious heart problems.
Tell your doctor if you are pregnant or breastfeeding.
Follow your doctor's instructions about using this medicine if you are pregnant or you become pregnant. Controlling diabetes is very important during pregnancy.
How should I use insulin glargine?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Insulin glargine is injected under the skin, usually once per day at the same time of day.
When treating type 1 diabetes, use your short-acting insulin before meals as directed by your doctor.
Insulin glargine must not be given with an insulin pump, or mixed with other insulins. Do not inject insulin glargine into a vein or a muscle.
Ask your doctor or pharmacist if you don't understand how to use an injection.
Prepare an injection only when you are ready to give it. Call your pharmacist if the medicine looks cloudy, has changed colors, or has particles in it.
Your healthcare provider will show you where to inject insulin glargine. Do not inject into the same place two times in a row.
Avoid injecting into skin that is damaged, tender, bruised, pitted, thickened, scaly, or has a scar or hard lump.
Toujeo contains 300 units of insulin glargine per milliliter (mL), which is 3 times stronger than brands that contain 100 units per mL.
Your dose needs may change if you switch to a different brand, strength, or form of this medicine. Avoid medication errors by using only the medicine your doctor prescribes.
If you use an injection pen, use only the injection pen that comes with insulin glargine. Attach a new needle before each use. Do not transfer the insulin from the pen into a syringe.
Never share an injection pen, even if you changed the needle. Sharing these devices can pass infections from person to person.
Blood sugar can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals.
Low blood sugar (hypoglycemia) can make you feel very hungry, dizzy, irritable, or shaky. To quickly treat hypoglycemia, eat or drink hard candy, crackers, raisins, fruit juice, or non-diet soda. Your doctor may prescribe glucagon injection in case of severe hypoglycemia.
Tell your doctor if you have frequent symptoms of high blood sugar (hyperglycemia) such as increased thirst or urination. Ask your doctor before changing your medication dosage.
