Lantus is a long-acting insulin used to control high blood sugar in people with diabetes. Lantus is available as vials and a prefilled SoloStar pen.
How does this medication work?
Your body needs insulin to turn sugar into energy. Diabetes develops when your body does not make enough insulin or does not properly use the insulin it makes. Lantus may help control your blood sugar levels by allowing blood sugar to move from your bloodstream into your cells for energy.
What are the beneficial effects of this medication and when should I begin to have results?
What: Lowering your blood sugar to a normal level may prevent or delay potential complications associated with diabetes, such as blindness, kidney failure, or heart problems. Lantus provides a steady release of insulin to help control blood sugar between meals and overnight for up to 24 hours. Because it works for 24 hours, Lantus is injected just once a day, which may make it easier for you to remember.
When: Lantus may control your blood sugar levels over the course of a day.
How do I know it is working?
Check your blood sugar regularly and as your healthcare provider tells you to. Your healthcare provider will also do regular blood tests to measure your blood sugar levels and your hemoglobin A1C (measures your average blood sugar levels over a 2- to 3-month period). Stay on your prescribed diet and exercise program, as this will also affect the results of your blood tests.
The following is not a full list of side effects. Side effects cannot be anticipated. If any develop or change in intensity, tell your healthcare provider as soon as possible. Only your healthcare provider can determine if it is safe for you to continue taking this medication.
More common side effects may include: low blood sugar, injection-site reactions, skin thickening at the injection site, itching, rash, swelling of your hands and feet, weight gain.
Symptoms of low blood sugar include: dizziness or lightheadedness, sweating, confusion, headache, blurred vision, slurred speech, shakiness, fast heartbeat, anxiety, irritability or mood changes, or hunger.
Less common side effects may include:
Serious and potentially life-threatening allergic reaction, with symptoms such as a rash all over your body, trouble breathing, fast heartbeat, or sweating.
Lantus may also cause low blood potassium levels.
Taking certain diabetes pills called thiazolidinediones (such as pioglitazone and rosiglitazone) with Lantus may cause heart failure in some people. This can happen even if you have never had heart failure or heart problems before. If you already have heart failure it may get worse while you take thiazolidinediones with Lantus. Tell your healthcare provider if you have any new or worse symptoms of heart failure including shortness of breath, swelling of your ankles or feet, or sudden weight gain.
Do not use Lantus if you are allergic to it or any of its ingredients.
Tell your healthcare provider about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Lantus. Also, talk to your healthcare provider about your complete medical history, especially if you have kidney or liver problems, heart failure or other heart problems, if you are taking a thiazolidinedione, or if you are pregnant, plan to become pregnant, or are breastfeeding.
The information below is based on the dosage guidelines your healthcare provider uses. Depending on your condition and medical history, your healthcare provider may prescribe a different regimen. Do not change the dosage or stop taking your medication without your healthcare provider's approval.
Type 1 Diabetes
Adults and children ≥6 years: Inject once a day. Your healthcare provider will prescribe the appropriate dose for you or your child, based on daily insulin requirements.
Type 2 Diabetes
Adults: Inject once a day. Your healthcare provider will prescribe the appropriate dose for you, based on your weight.
Your dose may need to change because of a change in level of physical activity or exercise, weight gain or loss, increased stress, illness, change in diet, or because of the medicines you take.
Inject Lantus exactly as prescribed by your healthcare provider. Do not change the amount of Lantus you inject or stop using it without first talking to your healthcare provider.
You may inject Lantus at any time during the day, but you must inject it at the same time every day.
Only use Lantus that is clear and colorless. If your Lantus is cloudy or slightly colored, return it to your pharmacy for a replacement.
Inject Lantus under the skin of your abdomen (stomach area), upper arm, or upper leg. Do not use Lantus in an insulin pump or inject it into your vein.
Change your injection site each time you inject Lantus to reduce the chance of developing a reaction.
Please review the information that comes with your medicine for detailed instructions.
Do not share your Lantus SoloStar pen with other people, even if the needle has been changed. You may give other people a serious infection, or get a serious infection from them.
Do not reuse needles. Always use a new needle for each Lantus injection.
Do not mix Lantus with any other type of insulin or liquid medicine.
Do not drive or operate heavy machinery until you know how Lantus affects you.
