Question 1

What is Insulin Glargine?

Accepted Answer

Insulin glargine is a long-acting, man-made version of the hormone insulin that helps regulate blood glucose levels. It works by facilitating the movement of sugar from the blood into body tissues for energy use and by reducing the amount of sugar produced by the liver.

This medication is a basal insulin analog designed to provide a consistent level of insulin in the body over a prolonged timeframe. It functions by mimicking the natural baseline insulin secretion typically produced by the body.

Question 2

What is Insulin Glargine used for?

Accepted Answer

Insulin Glargine is used to treat diabetes mellitus .

Question 3

How does Insulin Glargine work?

Accepted Answer

Mechanism of Action

Insulin glargine works by replacing the insulin that the body would normally produce. Insulin is a hormone that allows sugar (glucose) in the blood to enter cells, where it is used for energy.

This medication also helps manage blood sugar levels by:

Helping muscle and fat tissues take up sugar from the blood.

Preventing the liver from producing and releasing more sugar into the bloodstream.

Extended Release Profile

Insulin glargine is designed to be absorbed slowly after it is injected under the skin. Once it enters the fatty tissue, it forms tiny crystals that gradually dissolve and release the medicine into the bloodstream at a steady rate. This process allows the medication to work for a long duration, typically providing a consistent level of insulin for about 24 hours. Unlike some other types of insulin, it does not have a distinct peak in activity, which helps maintain stable blood sugar levels between meals and overnight.

Question 6

Accepted Answer

Common side effects of Insulin Glargine may include:

Hypoglycemia

Weight gain

Injection site reactions

Always consult with a healthcare professional about potential side effects.

Question 7

What drug class is Insulin Glargine?

Accepted Answer

Insulin Glargine belongs to the long-acting insulin drug class.

Question 8

What is the dosage of Insulin Glargine and how do I take it?

Accepted Answer

Administration

Insulin glargine is injected subcutaneously (under the skin) into the fatty tissue of the abdomen, thighs, or upper arms. It should be used once every 24 hours at the same time each day. It is important to rotate the injection site with each dose to reduce the risk of developing skin lumps, pits, or thickened skin at the injection area.

Preparation

Before use, check the insulin solution to ensure it is clear and colorless. Do not use the medication if it is cloudy, colored, or contains visible particles. Insulin glargine must not be diluted or mixed with any other type of insulin or solution, as this can change how the medication works.

Missed Dose

If you miss a dose of insulin glargine, contact your healthcare provider for specific instructions on when to take your next dose. Do not inject a double dose or extra insulin to make up for a missed one.

Question 9

Is Insulin Glargine safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Maintaining stable blood sugar levels is essential during pregnancy to reduce the risk of complications for both the parent and the developing baby. Insulin glargine is often used during pregnancy when insulin therapy is required to manage diabetes.

Available data from clinical studies and observational research have not identified a specific risk of major birth defects, miscarriage, or adverse outcomes associated with the use of insulin glargine during pregnancy. Because insulin requirements typically change throughout the course of pregnancy—often increasing during the second and third trimesters—frequent monitoring and dosage adjustments by a healthcare professional are necessary.

Breastfeeding

Insulin glargine is generally considered safe for use while breastfeeding. Insulin is a naturally occurring hormone in human milk, and any insulin glargine that passes into breast milk is likely to be broken down in the infant's digestive system rather than absorbed into their bloodstream.

Individuals who are breastfeeding may find that their insulin requirements change significantly compared to their needs before or during pregnancy. It is important to discuss blood sugar management and potential dosage adjustments with a healthcare provider during the postpartum period to ensure safety and effective glucose control.

Question 10

What forms and strengths does Insulin Glargine come in?

Accepted Answer

Available Forms

Insulin glargine is a long-acting insulin provided as a clear, colorless solution for injection under the skin. It is available in the following delivery formats:

Vials: Glass containers used with insulin syringes.

Pre-filled Pens: Disposable, single-patient-use injector devices that contain a built-in reservoir of insulin.

Cartridges: Units designed for use in specific reusable pen delivery systems.

This medication is intended for subcutaneous administration only and should not be used in insulin pumps or administered intravenously.

Question 11

What is the FDA approval status of Insulin Glargine?

Accepted Answer

FDA Approval Status

Insulin glargine was first approved by the U.S. Food and Drug Administration (FDA) in 2000. It is indicated to improve glycemic control in both type 1 and type 2 diabetes mellitus. The approval covers:

Adults with type 1 or type 2 diabetes.

Pediatric patients with type 1 diabetes.

In addition to the original reference product, the FDA has approved follow-on biologics and biosimilar versions of insulin glargine. This includes the 2021 approval of the first interchangeable biosimilar insulin product, which allows for substitution at the pharmacy level under certain conditions.

Regulatory History and Safety Reviews

The FDA has conducted post-market safety reviews for insulin glargine. Between 2009 and 2011, the agency investigated a potential association between insulin glargine and an increased risk of cancer based on several published epidemiological studies. After a comprehensive review, the FDA concluded that the evidence did not show a clear link between the medication and cancer risk, and no changes to the clinical use of the drug were recommended.

Boxed Warnings and REMS

Insulin glargine does not have a boxed warning, and there is no Risk Evaluation and Mitigation Strategy (REMS) required for its distribution. Regulatory requirements focus on standard labeling to prevent medication errors, such as the risk of hypoglycemia and the prohibition of sharing insulin pens or needles between patients to prevent the transmission of bloodborne pathogens.

Question 12

What should I know about Insulin Glargine and cost?

Accepted Answer

Factors Affecting Price

The price of insulin glargine is influenced by several factors, including the specific product version and how it is dispensed. Common factors include:

Product Type: Insulin glargine is available as a reference brand and as several biosimilar or follow-on products. Biosimilars are highly similar to the original product and are often offered at a lower cost.

Concentration and Delivery: This medication comes in different concentrations (such as U-100 or U-300) and delivery formats, including multi-dose vials and prefilled injection pens. The cost may differ between these options.

Insurance Coverage: Most insurance plans include at least one version of insulin glargine on their formulary, but the preferred brand and the associated copay can vary significantly between plans.

Financial Assistance

Many manufacturers provide savings programs or patient assistance for those who meet specific eligibility requirements. Patients may also find price differences between various retail pharmacies.
