Good Day, 1. What is Farxiga used for? Farxiga (dapagliflozin) is an SGLT2 inhibitor for type 2 diabetes, heart failure, and chronic kidney disease. It reduces blood sugar as well as provides protections for heart and kidneys-these are advantages I see daily in patients with multiple comorbidities. 2. What is metformin, and what is it used for? Metformin is a first-line agent for type 2 diabetes. It reduces glucose release from the liver and improves insulin sensitivity. It is also effective, inexpensive, and generally well-tolerated. 3. Are Farxiga and metformin safe to take together? Why or why not? Yes. They have different mechanisms of action and carry little risk of overlap for side effects. I often put patients on metformin and Farxiga in order to achieve better glucose control and provide organ protection. 4. Are there any specific dosages of the 2 medications deemed safe for combination treatment? Typical starters: metformin 500-1000mgbid, Farxiga 5-10mg daily. I start low and increase the dose according to lab results and patient's tolerance. Fixed-dose combinations exist but they're not first-line in initiating titration. 5. In your experience, why would Farxiga and metformin sometimes be prescribed together? Farxiga offers additional benefits of glucose control, cardiovascular protection, and renal protection in those instances in which metformin alone is simply not adequate. It becomes particularly valuable in individuals with cardiovascular risk or early kidney disease. 6. Are there risks to combining these medications? Yes--UTIs and dehydration from Farxiga; GI upset and, rarely, lactic acidosis with metformin. Renal function should be followed regularly. 7. What pearls or suggestions do you have for taking Farxiga and metformin together? Take metformin with food; Farxiga goes with morning fluids. Be hydrated, look for infections, and check labs every 3 to 6 months. 8. Any other comments? This combo works, and is very well tolerated, with benefits for glycemic control and long-term complications. It has become the preferred dual therapy of choice in contemporary diabetes management.

1. Farxiga (dapagliflozin) is a medication offering both blood sugar control and cardiovascular/renal protection, and is used to treat type 2 diabetes, heart failure, and chronic kidney disease. This medication works by blocking SGLT2 proteins in the kidneys, reducing glucose reabsorption and increasing glucose excretion in urine, which lowers blood sugar levels independently of insulin. 2. Metformin is a first-line oral medication for type 2 diabetes and works mainly by reducing glucose production in the liver, improving insulin sensitivity, and enhancing peripheral glucose uptake. 3. Yes, this combination is widely used and approved. Clinical evidence shows that this combination leverages complementary mechanisms with metformin reducing liver glucose production, while Farxiga increases urinary glucose excretion. This combination is available as a fixed-dose tablet like Xigduo, and no major safety concerns have been identified for this combination. 4. While there is no specific dosage for all patients to follow, there are recommended dosing ranges. With metformin, starting from 500 mg once or twice daily up to a maximum of 2000 mg per day, and for Farxiga, 5 mg or 10 mg once daily, with the 10 mg dose being most commonly used in combination therapy for type 2 diabetes. These doses should be adjusted based on patients' status, like responsiveness to therapy and kidney function. 5. These medications together show Complementary Mechanisms, as I explained in point 3. Metformin lowers blood glucose mainly by reducing liver glucose production and improving insulin sensitivity, while Farxiga (dapagliflozin) increases glucose excretion through the urine by inhibiting SGLT2 in the kidneys. Clinical studies show that this combination lowers HbA1c (a marker of long-term blood sugar) more than either drug alone, and both have a low risk of causing hypoglycemia compared to some other diabetes medications. And finally, Farxiga provides additional benefits, such as reducing the risk of heart failure and slowing kidney disease progression, which can be especially valuable for patients with these risks. 6. No, no major safety concerns have been identified for this combination. 7. Take the medications with food, as this reduces GI side effects from metformin. Stay well hydrated to prevent dehydration from Farxiga. Dr. Seyed Hassan Fakher MD Preventive Health & Sports Medicine https://www.linkedin.com/in/hassan-fakher-md-322615244/ Invigor Medical
