If you have type 2 diabetes, your doctor may recommend treatment with Soliqua 100/33. It’s a prescription drug used together with diet and exercise to help improve blood sugar levels in adults with type 2 diabetes.

Soliqua 100/33 isn’t used in certain cases, such as for treating type 1 diabetes. To learn more about this drug’s use, see “What is Soliqua 100/33 used for?” below.

Soliqua 100/33 basics

Soliqua 100/33 contains two active ingredients: insulin glargine and lixisenatide. (An active ingredient is what makes a medication work.)

Insulin glargine belongs to a group of drugs called long-acting insulins. And lixisenatide belongs to a group of drugs called glucagon-like peptide-1 receptor agonists. Both active ingredients are biologic medications, which are made from parts of living organisms.

Soliqua 100/33 isn’t available in a biosimilar form. (Biosimilars are like generic drugs. But unlike generics, which are made for nonbiologic drugs, biosimilars are made for biologic drugs.) The insulin glargine and lixisenatide combination is only available as the brand-name drug Soliqua 100/33.

Soliqua 100/33 comes as a liquid solution inside prefilled single-use pens. You’ll use these pens to give yourself an injection of the drug under your skin.

Your doctor will recommend the dosage of Soliqua 100/33 that’s right for you. Below are commonly used dosages, but always take the dosage your doctor prescribes.

Form and strength

Soliqua 100/33 comes as a liquid solution inside prefilled single-use pens. You’ll use these pens to give yourself an injection of the drug under your skin.

Each Soliqua 100/33 pen contains 3 milliliters of solution, with 300 total units of insulin per pen. There are five pens per box of Soliqua 100/33.

Recommended dosage

For treating type 2 diabetes, your doctor may recommend a low starting dose of Soliqua 100/33. Your doctor will prescribe a dose based on your current or past treatments for type 2 diabetes. Your dose may also be determined by your blood sugar levels.

Over time, your doctor may adjust the dose in response to your blood sugar levels or results of other lab tests. This is known as a dose titration. The goal is to find the right dose that works for you without causing side effects.

You’ll usually receive Soliqua 100/33 once per day.

For a detailed Soliqua 100/33 dosing chart, see the drug’s prescribing information. The chart lists possible doses up to the maximum dose for the drug. You can also ask your doctor or pharmacist for more information on Soliqua 100/33’s dosages.

Questions about Soliqua 100/33’s dosage

How does Soliqua 100/33 work?

Soliqua 100/33 contains two active ingredients, insulin glargine and lixisenatide. (An active ingredient is what makes a medication work.) Each active ingredient has its own mechanism of action (how it works to treat a condition):

  • Insulin glargine tells your body’s cells to bring in sugar from your blood. It also stops your liver from producing more sugar. Both actions help lower blood sugar levels.
  • Lixisenatide increases insulin levels in your body. It also slows down how quickly your digestive tract works. This lowers the amount of sugar in your blood after a meal. And it decreases how much glucagon your body makes. (Glucagon is a hormone that increases blood sugar levels.)

If you have additional questions about how Soliqua 100/33 works, talk with your pharmacist or doctor.

What’s the efficacy of Soliqua 100/33?

Soliqua 100/33 is used together with diet and exercise to help improve blood sugar levels in adults with type 2 diabetes.

Type 2 diabetes is a condition that causes blood sugar levels to become too high. Usually, the hormone insulin works to keep blood sugar in your body at healthy levels. But with type 2 diabetes, your body’s cells don’t respond to insulin like they should. Over time, your body may stop making its own insulin or may not make enough.

Without appropriate treatment, type 2 diabetes can cause some serious problems, including:
