Farxiga 2025 Price & Drug Interactions: Alcohol, Medications, and Safety Guide
Discover essential insights on Farxiga's interactions with medications, alcohol, supplements, and foods in 2025. Learn when to avoid Farxiga and how to manage its use safely.
Farxiga (dapagliflozin) is a prescription medication primarily used to manage type 2 diabetes and reduce the risk of heart and kidney complications. It works effectively alongside diet and exercise to help adults control blood sugar levels and improve overall health outcomes.
In addition to managing diabetes, Farxiga is prescribed to lower risks associated with specific health conditions, including:
- For adults with type 2 diabetes and heart disease or risk factors, it reduces the chance of hospitalization due to heart failure.
- For those with heart failure, Farxiga decreases the risk of urgent medical visits, hospital stays related to heart failure, and mortality from cardiovascular issues.
- For adults with chronic kidney disease, it helps prevent worsening kidney function, progression to end-stage kidney disease, hospitalizations due to heart failure, and death from heart or vascular problems.
Farxiga is administered orally as a tablet containing dapagliflozin, the active ingredient responsible for its therapeutic effects.
Drug interactions occur when one substance alters the expected effect of another, which can also be influenced by individual health conditions. Understanding these interactions is crucial for safe and effective use of Farxiga.
When Should Farxiga Be Avoided?
Certain health conditions or factors may increase the risk of adverse effects with Farxiga, making its use inadvisable. These contraindications include:
- Allergic reactions to Farxiga or its components.
- Type 1 diabetes, as Farxiga is not approved for this condition.
- Severe liver impairment or pancreatitis.
- Pregnancy during the second and third trimesters.
- Breastfeeding mothers.
Always consult your healthcare provider to determine if Farxiga is appropriate for your health status.
Alcohol and Farxiga: What You Need to Know
Consuming large amounts of alcohol while taking Farxiga is discouraged due to increased risk of ketoacidosis, a rare but serious side effect. Moderate or occasional alcohol intake should be discussed with your doctor to ensure safety.
Medications That May Interact with Farxiga

| Sulfonylureas | Glipizide (Glucotrol XL), glyburide (Diabeta), glimepiride (Amaryl) | Higher chance of hypoglycemia |
| Lithium | Lithobid | Reduced lithium effectiveness |
| Corticosteroids | Prednisone (Rayos), dexamethasone (Hemady) | May decrease Farxiga’s effectiveness |
| Fibric acid derivatives | Gemfibrozil (Lopid), fenofibrate (Tricor) | Enhanced Farxiga effect, risk of low blood sugar |

Understanding Key Drug Interactions
Insulin
Farxiga combined with insulin can amplify the risk of hypoglycemia. Your doctor may adjust insulin dosages and recommend frequent blood sugar monitoring to maintain safe levels.
Sulfonylureas
Using Farxiga with sulfonylureas also raises the risk of low blood sugar. Dosage adjustments and careful monitoring are essential.
Lithium
Farxiga may decrease lithium levels, potentially reducing its therapeutic effect. Regular blood tests are necessary to ensure proper lithium dosing.
Additional Interactions to Consider
Supplements and Herbs
Garlic supplements and chromium may lower blood sugar and, when taken with Farxiga, increase hypoglycemia risk. Discuss any supplements with your healthcare provider before use.
Food and Vaccines
No known interactions with food or vaccines have been reported. However, consult your doctor if you have concerns.
Lab Tests
Farxiga can affect results of glucose monitoring tests like 1,5-anhydroglucitol (GlycoMark) and urine glucose tests. Your doctor will select appropriate tests to monitor your diabetes management.
Cannabis and Farxiga
No documented interactions exist between Farxiga and cannabis or CBD products, but always inform your healthcare provider about any cannabis use.
Health Conditions Affecting Farxiga Use
Inform your doctor about any history of genital yeast infections, liver disease, pancreatitis, frequent urinary tract infections, planned surgeries, or pregnancy, as these may influence Farxiga’s safety and effectiveness.
