What is the Generic Prescription for Farxiga?
For many patients, understanding the generic equivalent of a brand-name medication is the first step toward significant cost savings. The generic name for the brand-name prescription drug Farxiga is dapagliflozin. This active ingredient belongs to a class of medications called sodium-glucose cotransporter 2 (SGLT2) inhibitors.
Unlike many generics, the initial launch of dapagliflozin involved an "authorized generic" version in the U.S. in 2024. This authorized version was marketed by Prasco Laboratories under a license from the brand manufacturer, AstraZeneca. An authorized generic is an identical copy of the brand-name drug in all respects, including active and inactive ingredients and appearance, but is sold under a generic label. Over time, as more generic manufacturers gain FDA approval, additional versions that may differ in appearance but are therapeutically equivalent enter the market, increasing competition and lowering prices.
How Dapagliflozin Works
Dapagliflozin functions by targeting the SGLT2 protein in the kidneys. This protein is responsible for reabsorbing glucose (sugar) and sodium from the urine back into the bloodstream. By inhibiting this protein, dapagliflozin causes the kidneys to excrete excess glucose and sodium from the body through urination. This mechanism results in several therapeutic benefits:
- For Type 2 Diabetes: It helps lower blood sugar levels.
- For Heart Failure: It reduces the workload on the heart by removing excess fluid and sodium.
- For Chronic Kidney Disease: It helps slow the progression of kidney damage by reducing stress on the kidneys.
Important Considerations for Switching to Generic
When considering a switch to generic dapagliflozin from brand-name Farxiga, it is essential to have an informed discussion with your healthcare provider. The primary motivation for switching is often cost, as generic versions almost always offer a more affordable price point.
Pharmacists can typically substitute the generic for the brand name unless a prescriber specifies otherwise. If you decide to make the change, the transition should be straightforward, as the two drugs are bioequivalent. The main difference is the cost and potentially the pill's appearance.
To ensure a smooth transition, consider the following steps:
- Consult your doctor: Discuss the change with your healthcare provider to confirm it is appropriate for your specific health needs.
- Speak with your pharmacist: They can provide the most current information on availability and pricing for the generic version.
- Check insurance coverage: Verify with your insurance provider whether the generic is covered and if there are any restrictions or formulary differences that might affect your out-of-pocket costs.

Common Side Effects of Dapagliflozin
As with any medication, dapagliflozin can cause side effects. Awareness of these is crucial for safe use. Patients should always discuss any side effects or concerns with their doctor.
- Common side effects include:
- Genital yeast infections (more common in women)
- Urinary tract infections (UTIs)
- Increased urination
- Stuffy or runny nose and sore throat
- Serious, less common side effects include:
- Ketoacidosis: A serious condition where high levels of acids (ketones) build up in the blood. This can occur even with blood sugar levels below 250 mg/dL. Symptoms include nausea, vomiting, stomach pain, and trouble breathing.
- Dehydration: A result of increased fluid and salt excretion. Signs include dizziness, lightheadedness, and weakness.
- Fournier's Gangrene: A rare but aggressive bacterial infection of the tissue in the genital and perineum area. Seek immediate medical attention if you experience pain, swelling, or redness in this area, especially with fever.
Lifestyle and Precautions
To maximize the benefits of dapagliflozin and minimize side effects, certain lifestyle adjustments and precautions are important:
- Stay hydrated: Drinking plenty of fluids can help mitigate the risk of dehydration.
- Regular monitoring: Your healthcare provider will monitor your blood sugar and kidney function periodically to ensure the medication is working safely and effectively.
- Diet and exercise: For diabetes management, dapagliflozin should be used in conjunction with a healthy diet and regular physical activity.
- Surgical procedures: Inform your doctor about any planned surgery. They may advise you to temporarily stop taking dapagliflozin to reduce the risk of ketoacidosis.
Conclusion
The generic prescription for Farxiga is dapagliflozin. This is a safe and effective alternative for the brand-name drug, offering substantial cost savings for many patients. Since the FDA requires generics to be bioequivalent to their brand-name counterparts, patients can expect the same therapeutic benefits. By discussing the switch with a healthcare provider and being aware of potential side effects, patients can confidently make the transition to generic dapagliflozin.
