Uses
1 INDICATIONS AND USAGE FARXIGA (dapagliflozin) is indicated: • To reduce the risk of sustained eGFR decline, end-stage kidney disease, cardiovascular death, and hospitalization for heart failure in adults with chronic kidney disease at risk of progression. • • To reduce the risk of cardiovascular death, hospitalization for heart failure, and urgent heart failure visit in adults with heart failure. • To reduce the risk of hospitalization for heart failure in adults with type 2 diabetes mellitus and either established cardiovascular disease or multiple cardiovascular risk factors. • As an adjunct to diet and exercise to improve glycemic control in adults and pediatric patients aged 10 years and older with type 2 diabetes mellitus.
Dosage
2 DOSAGE AND ADMINISTRATION • Assess renal function prior to initiation and then as clinically indicated. Assess volume status and correct volume depletion before initiating. (2.1) • To improve glycemic control, the recommended starting dose is 5 mg orally once daily. Dosage can be increased to 10 mg orally once daily for additional glycemic control. (2.2) • For all other indications, the recommended dosage is 10 mg orally once daily. (2.2) • See full prescribing information for dosage recommendations in patients with renal impairment. ( 2.2 , 2.3 ) • Withhold FARXIGA for at least 3 days, if possible, prior to major surgery or procedures associated with prolonged fasting.
Side Effects
6 ADVERSE REACTIONS The following important adverse reactions are described below and elsewhere in the labeling: • Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis [see Warnings and Precautions (5.1) ] • Volume Depletion [see Warnings and Precautions (5.2) ] • Urosepsis and Pyelonephritis [see Warnings and Precautions (5.3) ] • Hypoglycemia with Concomitant Use with Insulin and Insulin Secretagogues [see Warnings and Precautions (5.4) ] • Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene) [see Warnings and Precautions (5.5) ] • Genital Mycotic Infections [see Warnings and Precautions (5.6) ] • Most common adverse reactions (5% or greater incidence) were female genital mycotic infections, nasopharyngitis, and urinary tract infections.
Interactions
7 DRUG INTERACTIONS Table 4: Clinically Relevant Interactions with FARXIGA Insulin or Insulin Secretagogues Clinical Impact The risk of hypoglycemia may be increased when FARXIGA is used concomitantly with insulin or insulin secretagogues (e.g., sulfonylurea) [see Warnings and Precautions (5.4) ] . Intervention Concomitant use may require lower doses of insulin or the insulin secretagogue to reduce the risk of hypoglycemia. Lithium Clinical Impact Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Intervention Monitor serum lithium concentration more frequently during FARXIGA initiation and dosage changes. Positive Urine Glucose Test Clinical Impact SGLT2 inhibitors increase urinary glucose excretion and will lead to positive urine glucose tests.
Warnings
5 WARNINGS AND PRECAUTIONS • Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis: Consider ketone monitoring in patients with type 1 diabetes mellitus and consider ketone monitoring in others at risk for ketoacidosis, as indicated. Assess for ketoacidosis regardless of presenting blood glucose levels and discontinue FARXIGA if ketoacidosis is suspected. Monitor patients for resolution of ketoacidosis before restarting. (5.1) • Volume depletion: Before initiating FARXIGA, assess volume status and renal function in the elderly, patients with renal impairment or low systolic blood pressure, and in patients on diuretics. Monitor for signs and symptoms during therapy. 4 CONTRAINDICATIONS FARXIGA is contraindicated in patients with a history of a serious hypersensitivity reaction to dapagliflozin or any of the excipients in FARXIGA. Serious hypersensitivity reactions, including anaphylaxis and angioedema have been reported with FARXIGA [see Adverse Reactions (6.1) ] .
Pregnancy
8.1 Pregnancy Risk Summary Based on animal data showing adverse renal effects, FARXIGA is not recommended during the second and third trimesters of pregnancy. Limited data with FARXIGA in pregnant women are not sufficient to determine drug-associated risk for major birth defects or miscarriage. There are risks to the mother and fetus associated with poorly controlled diabetes and untreated heart failure in pregnancy (see Clinical Considerations ) .
