Jardiance is the brand name for empagliflozin, a prescription medicine used mainly for type 2 diabetes and, in some people, heart failure or chronic kidney disease. It works by helping the kidneys remove extra glucose through urine, and it may also provide heart and kidney benefits when prescribed appropriately.
Overview: what Jardiance is and what it treats
Jardiance is a prescription medication whose active ingredient is empagliflozin. It belongs to a group of medicines called sodium-glucose cotransporter-2 (SGLT2) inhibitors. These medicines are most commonly used to help manage type 2 diabetes, but doctors may also prescribe them for some people with heart failure or chronic kidney disease because of their wider protective effects.
For people with type 2 diabetes, Jardiance helps lower blood sugar in a way that does not rely only on insulin. In suitable patients, it may be used alone or together with other diabetes medicines, including metformin, insulin, or other oral treatments. It is not a substitute for healthy eating, physical activity, and regular medical follow-up, but it can be an important part of a broader treatment plan.
Jardiance is not typically used to treat type 1 diabetes, and it is not appropriate for every person with high blood sugar. A doctor considers kidney function, overall health, other medicines, and the treatment goal before prescribing it. In some patients, the goal is better glucose control; in others, the main aim may be support for heart or kidney health alongside care for type 2 diabetes.
How Jardiance works in the body

The kidneys normally filter glucose out of the blood and then reabsorb most of it back into the body. Jardiance blocks part of this reabsorption process. As a result, more glucose leaves the body in the urine, which helps lower the amount of sugar circulating in the blood.
This action can also lead to mild fluid loss, which is one reason some people notice more frequent urination after starting the medicine. That same effect may contribute to some of the cardiovascular and kidney benefits seen in selected patients, although the exact overall benefit depends on the individual and the reason the medicine is prescribed.
Because Jardiance works through the kidneys, kidney function is an important part of treatment planning. Doctors usually review blood tests before and during use. They may also consider whether the patient is taking diuretics, has a history of dehydration, or has other conditions that could affect how safely the medicine can be used.
Who may benefit from Jardiance

Jardiance may be helpful for adults with type 2 diabetes who need better blood sugar control, especially when lifestyle measures alone are not enough. It may also be considered when weight-neutral or modest weight-reducing treatment is preferred, or when there is concern about cardiovascular or kidney health. The best choice depends on the person’s full medical picture rather than on blood sugar alone.
Some people with heart failure or chronic kidney disease may also be candidates for empagliflozin, even if the discussion starts outside of diabetes care. In those situations, doctors assess symptoms, kidney test results, other medicines, and the presence of related conditions such as high blood pressure or fluid retention. Depending on the patient, care may overlap with evaluation for heart failure or kidney-related follow-up.
Jardiance is not suitable for everyone. A clinician may avoid or delay it in people with severe dehydration, certain acute illnesses, a history of diabetic ketoacidosis, or significantly reduced kidney function. It also needs careful review around surgery, prolonged fasting, or serious infection because these situations can change how the body handles glucose and fluids.
Common side effects and important safety concerns
Many people tolerate Jardiance well, but side effects can occur. Common ones include increased urination, thirst, and genital yeast infections. Some people may also experience urinary tract infections. These effects happen partly because more glucose is present in the urine, which can change the local environment and increase irritation or infection risk.
Another possible concern is dehydration, especially in older adults, people taking water pills, or those who do not drink enough fluids. Signs may include dizziness, weakness, faintness, or low blood pressure. If symptoms develop, the prescribing doctor should be informed, since treatment may need to be reviewed.
Rare but important complications include diabetic ketoacidosis, a serious condition that can sometimes happen even when blood sugar is not extremely high. Warning signs include nausea, vomiting, abdominal pain, unusual tiredness, deep or rapid breathing, or confusion. Very rare but severe genital or urinary infections are also possible and need urgent evaluation. Patients should never ignore persistent pain, fever, or rapidly worsening symptoms.
- Common: more frequent urination, thirst, genital yeast infection, mild urinary infection
- Needs prompt medical review: dizziness, poor fluid intake, persistent vomiting, severe weakness
- Needs urgent care: trouble breathing, confusion, severe abdominal pain, signs of ketoacidosis, or spreading genital infection
How doctors decide if Jardiance is right for someone
Choosing Jardiance is usually part of a step-by-step medical discussion rather than a one-size-fits-all decision. Doctors review blood sugar patterns, A1C results, kidney function, blood pressure, weight goals, current medicines, and past side effects from diabetes treatment. This helps determine whether Jardiance fits the patient’s needs and whether another approach may be safer or more effective.
Blood and urine tests are often part of assessment and follow-up. Kidney function testing is especially important because the medication depends on kidney filtration to work properly. Clinicians may also ask about frequent infections, fluid intake, episodes of low blood pressure, alcohol use, and any history of diabetic ketoacidosis.
People already being treated for cardiovascular or kidney conditions may have input from more than one specialist. In a multidisciplinary setting, care may include diabetes management, kidney assessment, and review of therapies used for heart failure treatment or supportive care for chronic metabolic disease. The goal is to balance expected benefits with practical safety considerations.
Taking Jardiance safely: daily use, monitoring, and self-care
Jardiance should be taken exactly as prescribed. Patients should not start, stop, or change the medicine on their own, even if they feel well. Diabetes and cardiometabolic conditions often require long-term treatment, and the effect of medication is best judged through follow-up visits and lab testing rather than by symptoms alone.
Good hydration is important, especially during hot weather, exercise, stomach illness, or when appetite is reduced. A doctor may give “sick day” instructions for times when temporary interruption of the medicine is safer, such as vomiting, severe diarrhea, fasting, or planned surgery. Patients should ask in advance what to do in those situations.
Self-care still matters greatly. A balanced diet, regular physical activity, sleep, and routine monitoring all support better results. Depending on the broader treatment plan, some patients may also receive diabetes treatment that includes nutrition counseling, glucose monitoring, and medication review. For kidney-related follow-up, doctors may also coordinate care connected with kidney disease treatment when appropriate.
When to seek medical care
Medical advice should be sought promptly if a person taking Jardiance develops symptoms of dehydration, such as dizziness, fainting, extreme thirst, or reduced urination. A clinician should also be contacted for painful urination, fever, worsening genital irritation, or repeated infections, since these may require treatment and reassessment of the medication.
Urgent care is important if there are warning signs of ketoacidosis or severe infection. These include nausea, vomiting, abdominal pain, unusual drowsiness, trouble breathing, confusion, or rapidly spreading pain, swelling, or redness around the genital or groin area. Even though these complications are uncommon, early assessment is important.
People with diabetes should also arrange routine medical follow-up rather than waiting for symptoms. Regular visits help review blood sugar trends, kidney function, cardiovascular risk, and whether the treatment plan still fits the patient’s needs. Near the end of the care pathway, some patients choose evaluation in specialized centers; Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat diabetes, heart, and kidney conditions for international patients.
Frequently asked questions
What is Jardiance used for?
Jardiance is used mainly to treat type 2 diabetes, and in some patients it is also prescribed for heart failure or chronic kidney disease. The exact reason for treatment depends on the person’s medical history, test results, and overall goals of care.
Is Jardiance the same as insulin?
No. Jardiance is not insulin and it works in a different way. It helps the kidneys remove excess glucose through urine, while insulin helps move glucose from the blood into cells.
Can Jardiance cause weight loss?
Some people may notice modest weight reduction while taking Jardiance, but it is not primarily a weight-loss medicine. Any change varies from person to person and should not be the only reason for using it.
What are the most common side effects of Jardiance?
Common side effects include more frequent urination, thirst, genital yeast infections, and sometimes urinary tract infections. Many side effects are manageable, but persistent or worsening symptoms should be discussed with a doctor.
Can Jardiance be taken with other diabetes medications?
Yes, it is often used together with other diabetes medicines, but the combination must be planned by a clinician. Some combinations may increase the risk of low blood sugar or dehydration, so monitoring is important.
Who should be careful with Jardiance?
People with reduced kidney function, dehydration risk, recurrent infections, or a history of diabetic ketoacidosis may need extra caution. It may also need to be paused during acute illness, surgery, or prolonged fasting, depending on medical advice.
