In this article:

Farxiga (dapagliflozin) is a brand-name prescription drug made by AstraZeneca and was approved by the U.S. Food and Drug Administration (FDA) in 2014 for Type 2 diabetes. Since then, its FDA-approved uses have expanded, now including kidney disease, heart failure, and Type 2 diabetes. The mechanism of action of Farxiga involves helping the body eliminate excess glucose (sugar) in the urine. It also helps the body remove sodium, which supports kidney and heart function. While brand-name drugs like Farxiga can be costly, people often want to know: When will a cost-saving generic be available? 

Is there a generic for Farxiga?

The pharmaceutical company Prasco currently markets a generic version of Farxiga. The generic is called dapagliflozin, which is the active ingredient in Farxiga. As of 2024, Prasco has offered an authorized generic version of dapagliflozin (more on authorized generics below).

Additionally, several other companies have tentative FDA approvals, meaning that their generic versions have met the requirements for FDA approval but cannot yet be marketed in the United States due to patent issues. As of January 2025, only the Prasco version of dapagliflozin is available in pharmacies.

What are the differences between brand name and generic Farxiga?

Although generic drugs may look different from their brand-name counterparts, they contain the same active ingredient and work in the same way. What’s more, authorized generics, specifically, are brand-name drugs without a brand name—they are marketed as generics by the company that makes the brand-name drug or another company approved by the brand-name manufacturer. 

While generics, including authorized generics, work the same as their brand-name counterparts, generics are much more affordable, often costing up to 85% less than the brand-name versions. 

Generic medications are the same as brand-name drugs in terms of safety and effectiveness. The FDA requires that generic manufacturers perform studies to show that their generics are bioequivalent to the brand-name drug, meaning that the generic drug results in the same concentrations in the blood over the same period as the brand. 

Prasco’s authorized generic dapagliflozin looks exactly the same as the brand name Farxiga. However, when additional companies receive approval to market their generic dapagliflozin products, they may vary in appearance and will not be exact replicas of the brand-name Farxiga. And, as more competition enters the market, the prices for generics may also become lower. 

According to the Association for Accessible Medicines, generic drugs are very popular. Ninety percent of prescription drugs in the United States in 2024 were filled for generic or biosimilar drugs. 

The following table summarizes important information about brand-name Farxiga and its generic, dapagliflozin.

Common side effects
Contraindications
  • You should not take Farxiga or generic dapagliflozin if you have an allergy to this medicine or any ingredient in this medicine.
Other considerations
  • Serious side effects may include diabetic ketoacidosis, dehydration, genital mycotic infections (including genital yeast infection in women and yeast infection of the penis in men), serious urinary tract infections, hypoglycemia (low blood sugar) in people with diabetes, necrotizing fasciitis (also called Fournier’s gangrene, a rare but life-threatening bacterial infection in the perineum), and serious allergic reactions. 
  • Before taking Farxiga, tell your healthcare provider about all of your medical conditions, including if you have Type 1 diabetes, use insulin, have had diabetic ketoacidosis, have a history of infections, liver problems, urination issues, or urinary tract infections, dehydration, or a history of pancreatitis, or have had pancreas surgery. Inform your provider if you drink a lot of alcohol, have recently changed your diet, or are eating less. Let your healthcare provider know if you are scheduled for surgery, as they may advise you to stop taking Farxiga before the procedure and provide guidance on when to restart it afterward. 
  • Tell your healthcare provider about all your medications (including Rx and OTC drugs, vitamins, and supplements). This will help your provider ensure there are no drug interactions. You may need a lower dose of insulin or a sulfonylurea drug (such as glimepiride, glipizide, or glyburide) to reduce the risk of low blood sugar while taking Farxiga. 
  • Consult your healthcare provider if you are pregnant, planning to become pregnant, or breastfeeding. This medicine should not be used in the second and third trimesters of pregnancy or while breastfeeding.

What are the off-label uses for Farxiga?

In addition to FDA-approved uses, healthcare providers sometimes prescribe medications for off-label (non-FDA-approved) uses. Farxiga (or generic dapagliflozin) may be prescribed—typically along with another medication, such as a GLP-1 agonist—off-label for weight loss. 

Although some drugs used for Type 2 diabetes are prescribed off-label for Type 1 diabetes, the prescribing information for Farxiga states that this medicine should not be used for Type 1 diabetes. This is because Farxiga significantly raises the risk of diabetic ketoacidosis (DKA, a condition where acids called ketones build up in the blood). DKA can be life-threatening, especially in people with Type 1 diabetes. 

How to switch from Farxiga to dapagliflozin

When prescribing this medicine, a healthcare professional will typically write the prescription as “Farxiga.” According to state laws, pharmacists can substitute generic versions of brand-name drugs unless you or your healthcare provider specifically request not to substitute the brand for a generic version. 

If you take brand-name Farxiga and wish to switch to generic dapagliflozin, ask your healthcare provider or pharmacist. Because the brand-name and generic products contain the same ingredients and are available in the same dosages, switching to generic should be an easy and seamless transition. 

If you are concerned about trying a generic form of Farxiga, you can always try it for one month. If you are not satisfied with the generic medicine after this time, you can ask your pharmacist to switch you back to brand-name Farxiga. 

Consult your healthcare provider for medical advice if you have any questions or concerns about your medications. 

Long-term use of Farxiga (dapagliflozin) 

You may be wondering about the benefits of long-term Farxiga use. Always consult your healthcare provider for medical advice, as everyone has a unique medical history. However, here are some general findings from long-term clinical trials of Farxiga. 

  • In people with Type 2 diabetes and heart disease, Farxiga was effective in reducing hemoglobin A1c (HbA1C, a measure of glycemic control over three months), systolic blood pressure, and body weight over two years. 
  • One study found that for middle-aged and older adults with both heart failure and mildly reduced or normal heart function, taking dapagliflozin helped them live 2.0 to 2.5 years longer without experiencing serious heart-related events (such as hospitalization, death, or worsening of their condition).
  • A study published in 2024 found that for people with Type 2 diabetes, taking Farxiga improved kidney health and reduced albuminuria (the presence of albumin, a protein in the urine commonly seen in people with kidney conditions).

In a study of people with chronic kidney disease (CKD), taking Farxiga helped delay serious problems like kidney failure, death, worsening kidney function, and hospital visits for heart failure. Farxiga may help slow kidney disease, possibly delaying kidney failure by about 6.6 years.
