Farxiga, a prescription medication primarily used to treat type 2 diabetes, has gained attention for its potential to promote weight loss. As more people seek effective ways to manage their weight, understanding the connection between Farxiga and weight loss has become increasingly important.

In this blog post, we’ll explore what Farxiga is, how it causes weight loss, and how rapid weight loss is with Farxiga.

Key Takeaways

  1. Farxiga is an SGLT2 inhibitor that helps manage type 2 diabetes by lowering blood sugar levels.
  2. Weight loss is a secondary benefit of Farxiga, resulting from its mechanism of action that promotes glucose excretion.
  3. The rate of weight loss with Farxiga may vary among individuals and can be influenced by diet and exercise habits.

What Is Farxiga?

Farxiga, also known by its generic name dapagliflozin, is a medication that belongs to the class of drugs called sodium-glucose co-transporter 2 (SGLT2) inhibitors.

It is primarily prescribed to individuals with type 2 diabetes to help manage their blood sugar levels. Farxiga works by blocking the action of SGLT2, a protein responsible for reabsorbing glucose from the kidneys back into the bloodstream.

By inhibiting SGLT2, Farxiga prevents the reabsorption of glucose and promotes its excretion through urine. This mechanism helps lower blood sugar levels, making it an effective tool in the management of type 2 diabetes. In addition to its blood sugar-lowering effects, Farxiga has also been observed to have a positive impact on weight loss.

Does Farxiga Cause Weight Loss?

Yes, Farxiga has been shown to cause weight loss in individuals taking the medication. While the primary purpose of Farxiga is to manage type 2 diabetes, weight loss is a notable secondary benefit that many users experience. The weight loss effect of Farxiga is directly related to its mechanism of action.

When Farxiga promotes the excretion of glucose through urine, it also leads to the elimination of calories from the body. Each gram of glucose excreted represents approximately 4 calories that are no longer available for absorption and storage. Over time, this calorie deficit can contribute to weight loss.

It’s important to note that weight loss with Farxiga is not solely due to the medication itself. Lifestyle factors, such as diet and exercise, also play a significant role in weight management. Combining Farxiga with a balanced diet and regular physical activity can enhance the weight loss effects and improve overall health outcomes.

How Rapid Is Weight Loss With Farxiga?

The rate of weight loss with Farxiga can vary among individuals and depends on several factors, including starting weight, adherence to the medication, and lifestyle habits. Clinical studies and research have provided some insights into the weight loss effects of Farxiga over time.

In a study published in the journal Diabetes, Obesity and Metabolism, researchers found that individuals with type 2 diabetes who took Farxiga experienced an average weight loss of 2.7 kg (5.9 lbs) over a 24-week period. This weight loss was sustained and even slightly increased to 3.3 kg (7.3 lbs) at the 102-week mark.

Another study, published in the Lancet Diabetes & Endocrinology, compared the weight loss effects of Farxiga to placebo in individuals with type 2 diabetes.

The researchers found that those taking Farxiga lost an average of 2.9 kg (6.4 lbs) more than the placebo group over a 24-week period.

It’s worth noting that the rate of weight loss with Farxiga may be more pronounced in the initial weeks of treatment and then gradually taper off over time. Individual results may also vary, with some people experiencing more rapid weight loss than others.

To maximize the weight loss potential of Farxiga, it’s essential to combine the medication with a healthy lifestyle. Adopting a balanced diet that focuses on whole foods, portion control, and limiting processed and high-calorie items can support weight loss efforts.

Engaging in regular physical activity, such as brisk walking, cycling, or swimming, can further enhance calorie expenditure and promote weight loss.

Farxiga: Dosing Guidelines And Side Effects

When considering Farxiga for weight loss or diabetes management, it’s crucial to follow the dosing guidelines provided by healthcare professionals. The recommended starting dose of Farxiga is typically 5 mg once daily, taken in the morning with or without food. If needed, the dosage may be increased to 10 mg once daily for additional glycemic control.

It’s essential to take Farxiga as prescribed and not to adjust the dosage without consulting a healthcare provider. Skipping doses or taking more than the recommended amount can lead to adverse effects and compromise the effectiveness of the medication.

Like all medications, Farxiga may cause side effects in some individuals. The most common side effects associated with Farxiga include:

  • Urinary tract infections
  • Genital yeast infections
  • Increased urination
  • Back pain
  • Nausea

These side effects are generally mild and tend to subside over time. However, if they persist or become bothersome, it’s important to consult a healthcare provider for guidance.

In rare cases, Farxiga may cause more serious side effects, such as dehydration, kidney problems, or diabetic ketoacidosis. It’s essential to be aware of the signs and symptoms of these complications and seek immediate medical attention if they occur.


Farxiga, primarily used to manage type 2 diabetes, has shown promise in promoting weight loss as a secondary benefit. Its mechanism of action, which involves the excretion of glucose and calories through urine, can contribute to a calorie deficit and support weight loss efforts.

The rate of weight loss with Farxiga may vary among individuals, but clinical studies have demonstrated an average weight loss of 2.7 to 3.3 kg (5.9 to 7.3 lbs) over a 24 to 102-week period. Combining Farxiga with a balanced diet and regular exercise can enhance weight loss results and improve overall health outcomes.

If you are considering Farxiga for weight loss or diabetes management, it’s essential to consult with a healthcare provider to determine if it is suitable for your specific needs. They can provide personalized guidance on dosing, monitor for potential side effects, and help you navigate your weight loss journey safely and effectively.

Remember, while Farxiga can be a valuable tool in promoting weight loss, it is not a magic solution. Sustainable weight loss requires a comprehensive approach that includes a balanced diet, regular physical activity, and a commitment to long-term lifestyle changes.


Q: Can I take Farxiga solely for weight loss, even if I don’t have type 2 diabetes?

A: No, Farxiga is primarily prescribed for the management of type 2 diabetes. It is not approved by the FDA as a weight loss medication for individuals without diabetes. Using Farxiga solely for weight loss without a proper diagnosis and prescription from a healthcare provider is not recommended.

Q: How long do I need to take Farxiga to see weight loss results?

A: The weight loss effects of Farxiga may vary among individuals. Clinical studies have shown that weight loss can occur within the first few weeks of treatment and continue over several months. However, individual results may differ, and the rate of weight loss can be influenced by factors such as diet, exercise, and overall health status.

Q: Can I stop taking Farxiga once I reach my weight loss goal?

A: It’s essential not to stop taking Farxiga without consulting your healthcare provider, even if you have reached your weight loss goal. Farxiga is primarily prescribed for the management of type 2 diabetes, and stopping the medication abruptly can lead to uncontrolled blood sugar levels. Your healthcare provider will guide you on the appropriate duration of treatment based on your individual needs and health status.

Q: Are there any dietary restrictions while taking Farxiga?

A: There are no specific dietary restrictions associated with Farxiga. However, it’s essential to follow a balanced and healthy diet to support weight loss and overall health. This includes focusing on whole foods, controlling portion sizes, and limiting processed and high-calorie items. It’s also crucial to stay hydrated and drink plenty of water while taking Farxiga to avoid dehydration, which can be a side effect of the medication.
