About Farxiga 

Farxiga is considered a sodium-glucose cotransporter 2 (SGLT2) inhibitor, which functions by aiding the kidneys in removing glucose from the body through urine. It is used to help control blood sugar in adults with type 2 diabetes mellitus.

Like any (DPP-4) inhibitors, you can only use this medication for as long as coupled with other diabetes medications like metformin or insulin, with a diet and exercise plan considered healthy. SGLT2 inhibitors can help increase the urination of glucose from the body to improve blood sugar control, especially in diabetic patients that don't have their diabetes under control.

It is ineffective against type 1 diabetes mellitus or diabetic ketoacidosis because it will not lower blood sugar that has high levels of ketones. Some conditions that Farxiga is known to treat include Type 2 diabetes, heart failure, and chronic kidney disease (CKD).

Farxiga is available only by prescription. It is available in a generic formulation under different brand names, including Farxiga (US).

Farxiga may be prescribed as a tablet. It's always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage you are prescribed.

If you are prescribed Farxiga, complete the entire course of the (SGLT2) inhibitors unless your doctor specifically tells you to stop. If you don't complete your prescription, the (SGLT2) inhibitors may not fully treat your diabetes, and your blood sugar levels may not be well controlled.

Farxiga uses

There are multiple FDA-approved uses for Farxiga, but you may also use it off-label to treat other conditions. Your online medical professional may prescribe it for the following reasons.

It's also possible that your physician may prescribe it for different reasons not listed here. Ask your online doctor or pharmacist if you have questions about why a medication is prescribed.

  • Type 2 diabetes

    Farxiga is FDA-approved for use in adults with type 2 diabetes. With FDA approval, Farxiga may be used by people with type 2 diabetes to:

    • Lower glucose levels when combined with a healthy diet and regular exercise.

    • Help those with heart problems or heart disease risk factors and avoid hospitalization for heart failure in adults.

    Diabetes is a disease that lasts for a long time. When you have diabetes, your blood sugar (glucose) levels rise. The hormone insulin typically aids in transporting glucose from the blood into the body's cells. (Glucose serves as an energy source after it enters your cells.)

    With type 2 diabetes, however, the body's cells do not react to insulin as they should. And if you have diabetes and it worsens, your body may not produce enough insulin.

    If you don't manage type 2 diabetes, your blood sugar level can always stay high. And this can lead to several problems that can be very serious, like heart failure.

  • Heart failure

    Farxiga is approved for the treatment of adults with heart problems. People who have a decreased ejection fraction (EF) are the ones who are prescribed this medication so that they may lower their risk of:

    • Hospitalized for heart failure

    • Cardiovascular death (issues with the heart or blood vessels).

    Heart failure occurs when the heart cannot effectively circulate blood throughout the body. Without enough blood supply, the body cannot perform its regular functions. Typical signs of heart failure include breathing problems, fatigue, and swelling in your ankles, legs, and feet.

  • Chronic kidney disease

    FDA-approved Farxiga reduces risks for individuals with chronic kidney disease (CKD), which may worsen. It prevents:

    • Low GFR, which indicates end-stage kidney disease.

    • Heart or blood vessel problems that cause cardiovascular disease.

    • cardiac hospitalization

    Chronic renal disease makes your kidneys less effective in filtering blood. This disease may progress to renal failure. Kidney symptoms include decreased urine, dark or blood in urine, tiredness, and high blood pressure.

    If you've experienced polycystic kidney disease, please let your physician know.

Farxiga side effects

  • The side effects of taking Farxiga are typically minor and inconsequential, but you may have a more severe reaction in some cases. Most side effects of Farxiga are associated with the medication's diuretic effect and include increased urinary tract infection, dry mouth, thirst, dizziness, or lightheadedness. Farxiga has some common side effects. They may include:

    Other side effects, which are less common but might be more severe, could include:

    • Hypoglycemia (low blood sugar level) or potentially fatal high blood sugar levels (hyperglycemia) if you have diabetes and are taking insulin or other diabetes medication

    • Allergic reaction: Trouble breathing; swelling of the face, lips, tongue, or throat.

    • Ketoacidosis: People with diabetes can get a dangerous condition called ketoacidosis. Ketoacidosis is a buildup of acids in the blood. Symptoms include nausea, vomiting, abdominal pain, tiredness, and shortness of breath.

    • Fournier's gangrene: A severe and potentially fatal condition involving tissue breakdown in the genitals or anus.

    • Dehydration: Because Farxiga causes you to urinate more frequently, it can also lead to dehydration.

    You should call your healthcare professional if you notice any of these side effects or develop other new or concerning symptoms.

    Farxiga in young children under age 12 is not advised because it can cause potentially fatal high blood sugar levels.

    Do not take Farxiga if you are allergic to dapagliflozin or any of the ingredients in Farxiga.

    Stop taking Farxiga and tell your doctor immediately if you become pregnant during treatment with Farxiga. If you are breastfeeding, you shouldn't take Farxiga. No one knows if the drug can enter the breast milk and harm the infant.

How to take Farxiga

Your pharmacist will provide you with instructions on how to take your Farxiga prescription.

Be sure to read your prescription label and follow the instructions. Call your doctor or pharmacy if you have any questions.

Farxiga can come in different forms and doses, so follow the specific instructions on your prescription. It is typically prescribed one time per day. 

Some specific instructions may include

  • Only take your dosage after first talking to your doctor.

  • Take Farxiga once daily by mouth, either with or without meals.

  • Follow the low-salt diet and exercise plan your healthcare professional gives you while taking Farxiga.

  • Your doctor may perform some blood tests throughout the course.

  • If you forget to take a dose, start taking it as soon as you think about it. If it's almost the period for your next daily dosage, skip the one you missed and take it when it's time again. Do not double dose.

  • Immediately call your healthcare professional or go to the closest emergency room if you take too much Farxiga.

What to avoid while taking Farxiga

Farxiga has 352 drug interactions, four diseases, and one food or drink. One drug interaction is a major, 26 minor, and 325 moderate. Don't change what you take without checking with your doctor or pharmacist. That includes other medications or supplements, as well as over-the-counter drugs. 

It is essential to avoid drinking alcohol while you are taking Farxiga. Alcohol can increase your risk of chronic diseases. Alcohol can increase the risk of low blood sugar. If you have diabetes and drink alcohol, you may also be more likely to get ketoacidosis.

Ask your doctor if it is acceptable to consume alcohol while taking Farxiga.

Some research shows that regular alcohol consumption may increase alcohol-related cancer risk. Alcohol may also reduce the medication's ability to do its job, making it harder to control blood sugar levels.
