Starting on LANTUS® FAQs

The questions and answers on this page are for educational purposes only. If you have questions about your health or treatment, please ask your doctor or healthcare provider.

Q: How often do I take LANTUS®?
A: Once a day. Most people take LANTUS® at bedtime, but you can take it at other times if your healthcare provider says it’s okay. Just take it every day, at the same time each day. You must test your blood sugar levels when taking insulin, such as LANTUS®.

Q: Can I use LANTUS® with diabetes pills?
A: Yes. LANTUS® is often taken along with oral medicines. Be sure to tell your doctor about other medicines and supplements you are taking because they can change the way insulin works.

Q: What should I do if I skip a shot of LANTUS®?
A: Your doctor has specific instructions for you regarding when to take LANTUS®. Before starting your LANTUS® regimen, be sure to ask your doctor what to do if you forget to take your insulin.

Q: What if the spot I inject gets red, swollen, or itchy?
A: This is called an injection-site reaction and should clear up within a few days or weeks. If it doesn’t go away, or if these reactions continue, tell your doctor. Make sure you change injection sites from one injection to the next.

Q: Will it take long to get to the right dose of LANTUS®?
A: Your healthcare provider may change your LANTUS® dose several times over the first few months. But stick with it—changing your dose to find what works best for you is important. Even after you find the right dose, your healthcare provider may adjust it from time to time. The goal will always be better blood sugar control.
