Brenzavvy (bexagliflozin) is a prescription medication in the class of sodium-glucose co-transporter 2 (SGLT2) inhibitors. It is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. It works by reducing glucose reabsorption in the kidney, thereby increasing urinary glucose excretion and lowering blood sugar. Brenzavvy requires a prescription and should only be taken under the supervision of a healthcare provider. It is not recommended for patients with type 1 diabetes.

Basics
What Is Brenzavvy?
Brenzavvy is the brand name for bexagliflozin. It is an effective agent for improving glycemic control (blood sugar levels) in adults with type 2 diabetes mellitus. Brenzavvy operates by targeting the sodium-glucose co-transporter 2 (SGLT2) in the kidneys. This action leads to the excretion of excess glucose in the urine, effectively lowering blood sugar levels. Patients with chronic conditions like type 2 diabetes often turn to Brenzavvy as part of a comprehensive management plan involving diet and exercise.
Note: This medication’s generic and brand-name formulations are used interchangeably throughout this article.
Indications
What Is Brenzavvy Used For?
Brenzavvy is primarily used as an adjunct to diet and exercise to treat and manage chronic type 2 diabetes mellitus. Its therapeutic use focuses on improving glycemic control.
Primary Indications
- Improve glycemic control in adults with type 2 diabetes mellitus: Brenzavvy is used to help manage high blood sugar, a key factor in the progression of type 2 diabetes and the risk of associated complications.
Mechanism
How Does Brenzavvy Work?
Understanding how Brenzavvy operates provides greater insight into its therapeutic effects and its role in diabetes care. The drug’s active ingredient, bexagliflozin, acts at the cellular level in the kidneys.
Mechanism of Action
Brenzavvy’s primary mechanism is to inhibit sodium-glucose co-transporter 2 (SGLT2), a protein responsible for reabsorbing the majority of filtered glucose from the bloodstream back into the body within the renal proximal tubule.
By blocking this transporter, Brenzavvy:
- Reduces the renal reabsorption of filtered glucose.
- Lowers the renal threshold for glucose.
- Increases urinary glucose excretion (UGE), thereby lowering blood glucose concentrations.
Pharmacokinetics
Bexagliflozin is well absorbed orally, with peak plasma concentrations (Cmax) reached between 2 and 4 hours post-dose. It is approximately 93% bound to plasma protein. The drug is mainly metabolized in the liver by UGT1A9 and, to a lesser extent, CYP3A. The terminal elimination half-life is approximately 12 hours. Elimination occurs primarily through feces and urine.
Dosage
Brenzavvy Dosages and Administration
Proper dosing and administration of Brenzavvy are vital to maximize its therapeutic benefits while minimizing potential risks.
Dosage Recommendations
- The recommended dosage of Brenzavvy is 20 mg orally taken once daily in the morning, with or without food.
- The dosage is the same for patients with normal renal function and those with mild to moderate hepatic impairment.
- Brenzavvy is not recommended in patients with an estimated glomerular filtration rate (eGFR) less than 30 mL/min/1.73 m².
Administration Guidelines
- Brenzavvy should be taken orally, with or without food, but maintaining a consistent morning dosing schedule is important.
- Patients must not crush or chew the tablet.
- If a dose is missed, take it as soon as possible. Do not double the next dose.
- Volume status and renal function should be assessed before initiating therapy, particularly in patients with impaired renal function, the elderly, those with low systolic blood pressure, or patients on diuretics, with volume depletion corrected prior to starting Brenzavvy.

Side Effects
Brenzavvy Side Effects and Risks
While Brenzavvy is effective in treating type 2 diabetes, like any medication, it comes with potential side effects and risks.
Common Side Effects (Incidence > 5%)
- Female genital mycotic infections
- Urinary tract infection
- Increased urination (which can include polyuria, pollakiuria, micturition urgency, and nocturia)
Serious Warnings and Risks
While less common, these serious conditions warrant immediate medical attention:
- Ketoacidosis: A serious, life-threatening condition that may occur even when blood glucose levels are below 250 mg/dL. If signs of severe metabolic acidosis occur, discontinue Brenzavvy and seek immediate medical evaluation.
- Lower Limb Amputation: An increased risk has been observed in some trials. Patients should be monitored for signs and symptoms of infection or ulcers of the lower limbs, and Brenzavvy should be discontinued if these complications occur. Routine preventative foot care is important.
- Volume Depletion (Dehydration): May lead to symptomatic hypotension or acute kidney injury. Monitoring for signs and symptoms of volume depletion is required during therapy.
- Urosepsis and Pyelonephritis: Serious urinary tract infections that may require hospitalization have been reported. Patients must be evaluated for signs and symptoms of urinary tract infections and treated promptly.
- Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene): A rare but serious and life-threatening infection. If suspected (pain, tenderness, erythema, or swelling in the genital/perineal area, along with fever), discontinue the drug and institute prompt surgical and antibiotic treatment.
- Hypoglycemia: The risk of low blood sugar increases when Brenzavvy is used with insulin or an insulin secretagogue (such as a sulfonylurea). A dose reduction of the concomitant medication may be necessary.
- Genital Mycotic Infections: Monitor patients for these infections and treat appropriately.
- Fractures: An imbalance in serious fractures was observed in a cardiovascular risk trial.
Interactions
Brenzavvy Interactions
Brenzavvy interacts with various other substances, which can influence its effectiveness and safety profile.
Primary Drug Interactions
- UGT Enzyme Inducers (e.g., Rifampin): These drugs can significantly reduce bexagliflozin exposure, leading to decreased efficacy. Consideration should be given to adding another antihyperglycemic agent.
- Insulin and Insulin Secretagogues: Hypoglycemia risk increases. A lower dose of the insulin or secretagogue may be needed.
- Lithium: Concomitant use may decrease serum lithium concentrations. Serum lithium concentration should be monitored more frequently upon Brenzavvy initiation and discontinuation.
Laboratory Interference
- Positive Urine Glucose Test: Brenzavvy increases urinary glucose excretion, resulting in a positive test result. Urine glucose tests are not recommended for monitoring glycemic control in patients taking SGLT2 inhibitors.
- 1,5-Anhydroglucitol (1,5-AG) Assay: Measurements of 1,5-AG are unreliable in assessing glycemic control. Alternative methods should be used.
Contraindications
Brenzavvy Contraindications
Certain conditions and situations preclude the use of Brenzavvy due to the substantial risks the medication poses.
Absolute Contraindications
- Known hypersensitivity to bexagliflozin or any excipient in Brenzavvy.
- Patients who are on dialysis.
Warnings and Precautions
- Severe Renal Impairment: Brenzavvy is not recommended in patients with an eGFR less than 30 mL/min/1.73 m² due to reduced glucose-lowering efficacy and an increased risk of adverse reactions.
- Severe Hepatic Impairment: Brenzavvy has not been studied in this patient population and is not recommended for use in this patient population.
- Pregnancy: Brenzavvy is not recommended during the second and third trimesters of pregnancy due to potential risks to the developing fetus’s kidneys.
- Lactation: Brenzavvy is not recommended while breastfeeding due to the potential risk to the developing human kidney from exposure in milk.

Side Effects & Safety
Common side effects of Brenzavvy include urinary tract infections, increased urination, and yeast infections. These side effects occur because glucose is excreted in the urine, providing a medium for microbial growth.
Serious side effects may include ketoacidosis, kidney problems, and severe allergic reactions. If you experience symptoms such as nausea, vomiting, or difficulty breathing, contact your doctor immediately.
Brenzavvy should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Consulting your doctor is essential to weigh the risks and benefits for both mother and child.
If you miss a dose, take it as soon as you remember. If it's nearly time for your next dose, skip the missed dose. Avoid taking a double dose to compensate for a missed dose, as this can lead to complications.
