What is Farxiga (Dapagliflozin)?
Farxiga is also known as Forxiga and it is an antidiabetic medicine used alongside diet and regular exercise to help lower blood sugar levels in adults with type 2 diabetes. Forxiga is a brand name medication. Its active ingredient is dapagliflozin, which is also the generic version of this medication. It belongs to the gliflozin family of antidiabetic medications.
What is it used for?
Farxiga is used to help lower blood sugar levels in adults with type 2 diabetes, and should not be used to treat people with type 1 diabetes, or those with diabetic ketoacidosis (an increase in ketones in your blood or urine).
How does Farxiga (Dapagliflozin) work?
Farxiga, like other members of the gliflozin family of antidiabetic drugs, works by decreasing the re-absorption of blood sugar back into your kidneys. With less blood sugar being absorbed back into the kidneys, more blood sugar is eliminated through your urine. This results in less sugar in your blood. Not only does it help control your blood sugar levels, but it also may also help you reduce your body weight and blood pressure.
How to take this medication
Farxiga is recommended to be taken in the morning, with or without food, but try to take your dose the same way each time. Always follow all the directions on your prescription label. Your doctor may change your dose from time to time in order for you to get the best results. Never take it in larger or smaller amounts or for longer than your doctor recommends.
The medication can be used:
- alone, if you cannot take Metformin,
- with Metformin
- with a Sulfonylurea
- with Metformin and a Sulfonylurea
- with Sitagliptin (with or without Metformin)
- with insulin (with or without Metformin)
Your blood sugar will likely need to be checked often, and you may also need to get other medical tests at your doctor’s office. Farxiga is only one part of your treatment program that should also include a healthy diet, regular exercise, weight control, and regular blood sugar level monitoring.
Report to your doctor about all the current medication you are taking, or any you start or stop using, especially:
- Diuretics (water pills)
- Heart or blood pressure drugs
- NSAIDs (nonsteroidal anti-inflammatory drugs) such as ibuprofen (Advil, Motrin), naproxen (Aleve), and others
Farxiga (Dapagliflozin) Dosage
The recommended starting dose is 5 mg once daily, taken in the morning, with or without food. Your doctor may increase your dose to 10 mg once daily if you are tolerating the drug well and require additional blood sugar level control. You should have your kidney function monitored before, during and after taking the drug.
If used in combination with insulin, or any related drugs, your doctor will likely prescribe a lower dose of insulin or the related drug in order to reduce the risk of low blood sugar.
If you should happen to miss a dose, take it as soon as possible. If you do not happen to remember until it is almost time for your next dose, skip the dose you missed, and go back to your regular dosing schedule. Do not take a double dose to make up for missed doses.
