Jardiance (empagliflozin) is a prescription medication used to treat type 2 diabetes mellitus. It belongs to a class of drugs known as sodium-glucose cotransporter 2 (SGLT2) inhibitors. Jardiance works by helping the kidneys remove glucose from the bloodstream through the urine, thereby lowering blood sugar levels.

How Does Jardiance Work?

Jardiance works by inhibiting the SGLT2 protein in the kidneys, which is responsible for reabsorbing glucose back into the bloodstream. By blocking this protein, Jardiance helps to increase the amount of glucose excreted in the urine, thereby reducing blood sugar levels in individuals with type 2 diabetes.

Precautions and Warnings With Jardiance


  • Severe Kidney Impairment: Individuals with severe kidney impairment or those on dialysis should not take Jardiance.
  • Hypersensitivity Reactions: People with a history of serious hypersensitivity reactions to Jardiance or any of its components should avoid its use.


  • Urinary Tract Infections: Patients with a history of urinary tract infections or those at risk for urinary tract infections should use caution when taking Jardiance.
  • Hypotension: Jardiance may lead to low blood pressure, particularly in individuals taking diuretics or with a history of hypotension.
  • Hydration Status: Patients are encouraged to drink plenty of fluids while taking Jardiance to prevent dehydration, especially during periods of increased fluid loss (e.g., due to diarrhea, vomiting, or excessive sweating).
  • Surgery and Medical Procedures: Inform healthcare providers about all medications you are taking, including Jardiance, before undergoing surgery or medical procedures.


  • Kidney Function: Jardiance may cause changes in kidney function and may lead to serious kidney problems, including kidney failure.
  • Genital Yeast Infections: Jardiance may increase the risk of genital yeast infections, especially in women.
  • Dehydration: Jardiance can lead to dehydration, especially in elderly patients or those taking diuretics (water pills).
  • Hypoglycemia: Jardiance may increase the risk of hypoglycemia (low blood sugar) when used in combination with insulin or insulin secretagogues.

Why is Jardiance so Expensive?

  • Research and Development Costs: The development of medications like Jardiance involves extensive research, including preclinical studies, clinical trials, and regulatory approvals. Pharmaceutical companies must recoup these costs, which contributes to the pricing of the medication.
  • Innovation and Patent Protection: Jardiance is a product of innovative research aimed at addressing unmet medical needs. As pharmaceutical companies continue to invest in developing new treatments and technologies, they rely on patent protection to safeguard their investments. During the period of patent exclusivity, companies have the sole right to manufacture and sell the medication, allowing them to set prices without competition from generic alternatives.
  • Manufacturing Expenses: The production of medications like Jardiance involves sophisticated manufacturing processes and quality control measures to ensure consistency, purity, and potency. These processes require specialized facilities, equipment, and trained personnel, all of which contribute to the overall cost of production.
  • Regulatory Compliance: Pharmaceutical companies must adhere to strict regulatory standards set by government agencies such as the Food and Drug Administration (FDA). Compliance with these standards involves additional costs related to testing, documentation, and regulatory submissions to ensure the safety, efficacy, and quality of the medication.
  • Marketing and Distribution: Pharmaceutical companies invest in marketing and distribution efforts to promote awareness of their medications among healthcare providers and patients. These expenses include advertising, sales representatives, educational materials, and distribution networks, all of which contribute to the overall cost of bringing the medication to market.
  • Limited Competition: Brand-name medications like Jardiance may face limited competition from generic alternatives, particularly during the period of patent exclusivity. The absence of generic competition allows pharmaceutical companies to maintain higher prices for their brand-name medications until patents expire and generic versions become available.

Jardiance Alternatives

While Jardiance is a commonly prescribed medication for the treatment of type 2 diabetes mellitus, there are several alternative medications available that healthcare providers may consider based on individual patient factors and treatment goals:

  • Metformin: Metformin is a commonly prescribed medication for the treatment of type 2 diabetes mellitus. It works by decreasing glucose production in the liver and improving insulin sensitivity in the body.
  • SGLT2 Inhibitors: Similar to Jardiance, other SGLT2 inhibitors such as dapagliflozin (Farxiga) and canagliflozin (Invokana) are available as alternative treatment options for type 2 diabetes. They work by inhibiting glucose reabsorption in the kidneys, leading to increased glucose excretion in the urine.
  • GLP-1 Receptor Agonists: GLP-1 receptor agonists like liraglutide (Victoza) and dulaglutide (Trulicity) are injectable medications that stimulate insulin secretion and decrease glucagon production, leading to improved blood sugar control in patients with type 2 diabetes.
  • DPP-4 Inhibitors: DPP-4 inhibitors such as sitagliptin (Januvia) and saxagliptin (Onglyza) are oral medications that work by inhibiting the enzyme dipeptidyl peptidase-4 (DPP-4), which regulates blood sugar levels by breaking down incretin hormones.
  • Insulin Therapy: Insulin therapy is a cornerstone of treatment for type 2 diabetes in patients who require additional glycemic control despite oral medications. Various forms of insulin, including rapid-acting, short-acting, intermediate-acting, and long-acting formulations, are available to meet individual patient needs.

Questions About Jardiance
