Can you mix Humalog and Lantus
Nathan Sanders
Published Apr 26, 2026
Official Answer. No, you should never mix Humalog (insulin lispro) and Lantus (insulin glargine) insulins together in the same syringe. Lantus should never be mixed in the same syringe with any other insulin or injectable medication.
Are Humalog and Lantus interchangeable?
Lantus (insulin glargine [rdna origin]) and Humalog (insulin lispro [rDNA origin]) are both forms of insulin used to treat type 1 (insulin-dependent) or type 2 (non insulin-dependent) diabetes. A difference is that Humalog is usually given together with another long-acting insulin.
Can you mix Lantus and Humulin?
No interactions were found between Humulin R and Lantus. This does not necessarily mean no interactions exist. Always consult your healthcare provider.
Can you give Lantus and regular insulin at the same time?
Can I mix Lantus with another insulin? No.Do not mix Lantus with any other insulin or solution. It will not work as intended, and you may lose blood sugar control, which could be serious.What insulin Cannot be mixed?
Some insulins, like glargine (Lantus®) and detemer (Levemir®), cannot be mixed. Other insulins (NovoLog 70/30®, Humalog 75/25®) are already a combination of two types of insulin and should not be mixed. Wash your hands with warm water and soap. Dry your hands.
Can you mix short-acting and long-acting insulin?
For a mixed dose, putting sufficient air into both bottles before drawing up the dose is important. When mixing rapid- or short-acting insulin with intermediate- or long-acting insulin, the clear rapid- or short-acting insulin should be drawn into the syringe first.
Can Lantus and actrapid be given together?
Glargine (Lantus) is the best choice we have nowadays to better cover the basal requirement between the mealtime boluses which can be an analog (Humalog or Novolog), Regular (Actrapid) or a mixture of the two. Note that any of these should never be mixed with glargine.
Should I eat before or after taking Lantus insulin?
Lantus works continuously in the background and does not need you to eat food when you inject it at your usual time.What's the difference between Humalog and Lantus insulin?
Lantus (insulin glargine) is an effective, long-acting insulin that provides all-day blood sugar control, but it can cause low blood sugar levels, so be sure to have a source of sugar nearby. Lowers blood sugar. Humalog (insulin lispro) is a fast-acting insulin that controls blood sugar around meal times.
Why is Lantus given at night?Lantus is designed to give a steady level of insulin over 24 hours, even when you are not eating such as between meals and overnight. This helps keep blood glucose levels consistent during the day and at night.

NPH (brand name Humulin N or Novolin N) is an intermediate-acting insulin that starts working in about 1 to 2 hours and can last from 16 to 24 hours. Insulin glargine (brand name Lantus) is a newer form of long-acting insulin. It starts to work within 1 to 2 hours and continues acting for about 24 hours.
Is Humulin insulin the same as Lantus?
Humulin R is a short-acting form of insulin and Lantus is a long-acting form of insulin.
Can I mix Humalog and Humulin R?
If Humalog is mixed with a longer-acting insulin, such as Humulin N or Humulin U, Humalog should be drawn into the syringe first to prevent clouding of the Humalog by the longer-acting insulin. Injection should be made immediately after mixing. Mixtures should not be administered intravenously.
Can you mix Lantus and NovoLog?
Prepare your insulin. NovoLog can be mixed with insulin NPH (intermediate-acting insulin), but always draw NovoLog into the syringe first. Never mix NovoLog with Lantus. Do not mix NovoLog with other insulins if using an insulin pen or external pump.
What insulin can you mix with regular insulin?
Regular insulin is usually given 30 minutes before a meal. It can also be mixed in the same syringe with longer-acting NPH insulin or given separately immediately after each other.
Why Lantus Cannot mix with other insulins?
Remember: These long-acting insulins can’t be mixed in the same syringe with other insulins – this could change how the insulin works. Insulin glargine forms clusters when it is injected under the skin. As the individual insulin units detach from the cluster, the insulin analog can be absorbed into the blood stream.
How do you give a Lantus insulin shot?
That covers the 6 steps for preparing and injecting Lantus® with the Lantus® SoloSTAR® pen. Let’s do a quick review: Step 1: Prepare for an injection; Step 2: Attach a new needle; Step 3: Perform an air shot or safety test; Step 4: Select the dose; Step 5: Inject the dose; Step 6: Remove the needle. Thank you, Nancy.
Is it better to take long acting insulin in the morning or at night?
Ideally, basal insulin should produce at most a 30 milligrams per deciliter (mg/dL) change when blood sugar levels are stable and in your target range during sleep times. That’s why your healthcare provider will most likely advise you to inject basal insulin at night, preferably before bedtime.
When mixing insulin which goes first?
When you mix regular insulin with another type of insulin, always draw the regular insulin into the syringe first. When you mix two types of insulins other than regular insulin, it does not matter in what order you draw them into the syringe.
What is the sliding scale for insulin?
The term “sliding scale” refers to the progressive increase in pre-meal or nighttime insulin doses. The term “sliding scale” refers to the progressive increase in the pre-meal or nighttime insulin dose, based on pre-defined blood glucose ranges. Sliding scale insulin regimens approximate daily insulin requirements.
Why do you draw up clear before cloudy insulin?
The rapid- or short-acting insulin (clear) is drawn up first to prevent the intermediate-acting insulin (cloudy) from getting into the rapid- or short-acting insulin bottle and affecting the onset, peak, and duration.
Is Humalog fast acting?
Humalog is a fast-acting insulin that starts working faster and works for a shorter period of time than regular human insulin. Humalog is taken within 15 minutes before eating or right after eating a meal.
When should you not take Lantus?
Do not take Lantus during episodes of low blood sugar or if you are allergic to insulin or any of the inactive ingredients in Lantus. Do not share needles, insulin pens, or syringes with others.

Lantus and Basaglar are both FDA-approved to lower blood sugar levels in adults and children with type 1 diabetes. They are also both approved to lower blood sugar levels in adults with type 2 diabetes.
Do you check blood sugar before Lantus?
It’s important to test your blood sugar levels. Your dose may increase based on your insulin needs. Your dose will probably change during your first few months taking Lantus®.
Do you still give Lantus if blood sugar is low?
You should not use Lantus if you are having an episode of hypoglycemia (low blood sugar), or if you are in a state of diabetic ketoacidosis (call your doctor for treatment). Never share a Lantus SoloStar pen or cartridge with another person.
How quickly does Lantus work?
Long-acting: It begins working around four hours after injection and it has the ability to work for up to 24 hours. These insulins do not peak but are steady throughout the day. Examples of long-acting insulin including glargine (Lantus) and detemir (Levemir).
Can you give Lantus twice a day?
Lantus may be given at any time of the day, as long as the dose is given consistently the same time daily to prevent a rise in blood glucose levels.
How much is too much Lantus?
There is no universally agreed-upon maximum volume for subcutaneous administration. Although one reference suggests a maximum up to 5 mL,3 a maximum of 2-3 mL is likely more reasonable. Because insulin glargine is supplied as 100 units/mL, a volume of 2 mL represents a single-dose of 200 units.
Is Humulin the same as Humalog?
Humulin R is a form of short-acting insulin and Humalog is a rapid-acting human insulin analog.
Can you take 70/30 with Lantus?
No interactions were found between Lantus and NovoLog Mix 70 / 30. This does not necessarily mean no interactions exist. Always consult your healthcare provider.
