Can I take Lantus® with diabetes pills?
Yes. Lantus® is often taken along with other diabetes medicines. It's important to tell your doctor about all medicines and supplements you are taking because they can change the way insulin works.
Will it take long to get to the right dose of Lantus®?
Your doctor 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 doctor may
adjust it from time to time.
How often do I take Lantus®?
Once a day, at the same time each day. Most people take Lantus® at bedtime, but you can take it at other times if your healthcare professional
says it’s okay. You must
check your blood sugar levels
when taking insulin, such as Lantus®.
Can I inject cold insulin?
It’s advised that, before you inject, remove it from the refrigerator an hour or two before
you use it—cold insulin can be more uncomfortable to inject. Do NOT refrigerate your pen once it is in use. Learn more.
What should I do if I skip a shot of Lantus®?
Your doctor has specific instructions for you regarding when to take Lantus®. Before starting Lantus®, ask your doctor what to do if you forget to take your insulin.
When should I call my doctor?
Aside from your regular visits, there are a few specific times when you should call your doctor. Ask your doctor when you should call. For example,
if you think you are having side effects from Lantus®, call your doctor. Contact your doctor immediately if your blood sugar levels remain consistently high, or call if your blood sugar levels remain consistently low.
When you’re sick, you may have a more difficult time keeping your blood sugar levels within target range.
During times of illness, it is important to monitor your blood sugar levels more frequently.
What is hyperglycemia? What is hypoglycemia?
Hyperglycemia is the technical term for high blood sugar (glucose).
Hypoglycemia is when your body has an abnormally low level of blood sugar (glucose). In other words,
your body has too much insulin relative to the amount of glucose.
Several factors can contribute to
changes in blood sugar levels in people with diabetes, including food, physical activity, illness, or
How can I organize my supplies?
At home, one simple way is to keep your active pen, alcohol swabs, needles, and sharps container
all together in a basket or bag next to your bed or in the bathroom cabinet out of reach of children. When you’re on the go,
keep them in your travel bag, computer bag, briefcase, sports bag, or other carry bag. If you are
currently taking Lantus®, you can also get a free carrying case when you
sign up for more Lantus® information.
Sometimes, the spot where I inject gets red, swollen, or itchy. What is that?
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. Click here to learn more about injection sites.
What happens if I don’t rotate injection sites?
As with all insulins, injection sites should be rotated between the abdomen, thigh, and upper arm from one
injection to the next. Using the same spot every time you inject will toughen up the skin over time, which
may affect your body’s ability to absorb the insulin.
Can I use the same needle more than one time?
No, always attach a new, sterile needle. Using the same needle can block the insulin from injecting correctly, may cause contamination or spread infection.
Do I need to do a safety test?
Yes, you should always perform the safety test before each injection. This removes air bubbles and ensures
that the pen and needle are working properly.
Lantus® SoloSTAR® Pen
Is the Lantus® that’s in the Lantus® SoloSTAR® pen the same as in the Lantus® vial?
Yes. The Lantus® that comes in the vial is the same Lantus® that’s prefilled in the SoloSTAR® pen.
The only difference is that it comes in the pen.
Do needles come with the pen, and which needles are recommended?
No. Needles are prescribed separately by your doctor. The Lantus® SoloSTAR® pen is compatible with BD-brand needles. Be
sure to follow the instructions that come with your pen and your needles.
How many doses can I get out of the pen?
The injection discomfort you may feel varies from person to person. The pen comes prefilled with 300 units. How many doses you get from that will depend
on what your doctor prescribes for you.
Does using the Lantus® SoloSTAR® pen hurt?
The injection discomfort you may feel varies from person to person. The pen uses a small and very thin needle. The insulin is injected into the fatty layers just
under your skin, where there are fewer nerve endings than in other places.
Do I need to use a new pen each time I give myself an injection?
No, you do not need to use a new pen each time you give yourself an injection. However, the needle
does have to be changed with every dose. Each Lantus® SoloSTAR® pen contains 300 units of insulin.
Use the same pen until there is no more insulin left. The pen can be used for 28 days once you open it.
Why do I have to hold the Lantus® SoloSTAR® pen in for 10 seconds?
It is important to keep the injection button pressed all the way in and to slowly count to ten before
withdrawing the needle from the skin. After a full injection, the number in the dose window will return to zero. These steps ensure that the full
dose has been delivered. To help ensure an accurate dose each time, follow all steps
in the instruction included with your Lantus® SoloSTAR® pen. You may also
want to take a moment to review your injection techniques by watching the video
Injecting with the Lantus® SoloSTAR® Pen.
Why does insulin sometimes come out after I inject with the pen?
One reason is that you may not be leaving the needle under the skin long enough.
After the injection button is pressed, be sure to count to 10 before you withdraw
the needle from the skin. You may also want to take a
moment to review your injection techniques by watching the video
Injecting with the Lantus® SoloSTAR® Pen.
What do I do if there is not enough insulin left in the pen for my injection?
The Lantus® SoloSTAR® pen prevents you from dialing past the number of units left in the pen. If there
isn’t enough insulin for your full dose, you can complete your dose by calculating how much more you will
need from a new pen. For example, if you normally use 41 units and there are only 12 units left in your pen,
you will need 29 units from the new pen. Inject the remaining insulin from the first pen, and then inject
the appropriate amount with the new pen to complete your dose. Or, you can just use a new pen for your
full dose. Always remember to check the dial at each injection to be sure you’re getting the correct dose.
How do I take care of the Lantus® SoloSTAR® pen?
It’s important to protect your pen from dust and dirt, so you can clean the outside of your SoloSTAR®
pen by wiping it with a damp cloth. Do not run it under water or use any soap or solvents.
The pen costs more than the vial. Do I get more doses out of the pen?
It depends on how the prescription is written. With the Lantus® SoloSTAR® pen, you can receive up to
500 more units of insulin per prescription for the same copay as a vial and syringe under most major
insurance plans. Ask your pharmacist or doctor for more information.
Is there any special way that the Lantus® SoloSTAR® pen has to be discarded?
Always discard the pen with the pen cap on. You can discard it in the regular trash. But always discard the
needles the way your healthcare professional told you to do it. Also visit www.safeneedledisposal.org.
What do I do if my Lantus® SoloSTAR® pen jams?

The most common side effect of insulin, including Lantus®, is
low blood sugar (hypoglycemia), which may be serious. Some people may
experience symptoms such as shaking, sweating, fast heartbeat, and blurred vision.
Severe hypoglycemia may be serious and life-threatening. It may cause harm to your
heart or brain. Other possible side effects may include injection site reactions,
including changes in fat tissue at the injection site, and allergic reactions, including
itching and rash. In rare cases, some allergic reactions may be life-threatening.
