Why Was I Prescribed Diabetes Medicine for Heart Failure?

If you have recently been prescribed a diabetes medication for heart failure, you are not alone. Many people are surprised when they leave their doctor's office with a prescription for a medicine they believed was only used to treat diabetes.

One of the most common questions patients ask is:

"Why am I taking diabetes medicine if I do not have diabetes?"

The answer is that medicine is constantly evolving.

Researchers sometimes discover that a medication developed for one condition also provides important benefits for another. In recent years, this has happened with a group of medicines known as SGLT2 inhibitors.

Today, these medications are recommended in many heart failure treatment guidelines around the world because research has shown they can help many people living with heart failure, even if they have never had diabetes.

Originally developed for diabetes

SGLT2 inhibitors were first developed to help people with type 2 diabetes lower their blood sugar levels.

They work by helping the kidneys remove excess glucose through the urine.

During large clinical trials, researchers noticed something unexpected.

People taking these medicines experienced fewer hospital admissions for heart failure and better cardiovascular outcomes than expected. This observation led researchers to study whether these medicines could directly benefit people living with heart failure.

The results changed the way heart failure is treated.

What the research found

Large clinical trials found that certain SGLT2 inhibitors reduced the risk of hospitalization for heart failure and improved outcomes in many patients, regardless of whether they had diabetes.

As a result, cardiologists around the world now prescribe these medicines to many patients with heart failure.

This is why your doctor may recommend one, even if your blood sugar levels are completely normal.

How do these medicines help?

Researchers are still studying exactly how these medicines work, but several factors are believed to contribute.

They may help the body remove excess fluid, reducing pressure on the heart.

They may improve the way the heart produces and uses energy.

They may help protect kidney function, which is closely connected to heart health.

They may also reduce stress on the cardiovascular system.

Rather than acting only as diabetes medicines, these medications appear to provide several benefits that support both the heart and kidneys.

Common diabetes medicines used for heart failure

Several medications belong to the SGLT2 inhibitor family. Depending on your country and your individual health needs, your doctor may prescribe one of the following.

Jardiance

Jardiance, also known by its generic name empagliflozin, is one of the most commonly prescribed SGLT2 inhibitors for heart failure.

Large clinical studies have shown that it can reduce the risk of hospitalization for heart failure in many patients, including people who do not have diabetes.

Farxiga

Farxiga, also known as dapagliflozin, is another widely prescribed medication for heart failure.

Research has shown it can improve outcomes for many people living with heart failure, regardless of whether they have diabetes.

Other SGLT2 inhibitors

Other medicines in this family may also be prescribed in certain situations depending on your country, local treatment guidelines, and your healthcare provider's clinical judgement.

Your doctor will recommend the medication that is most appropriate for your individual circumstances.

How does my doctor choose which medicine is right for me?

There is no single medication that is right for everyone.

Your doctor considers many factors before recommending treatment, including:

Your type of heart failure.

Your kidney function.

Other medical conditions.

Current medications.

Your overall health.

Current clinical guidelines.

This is why two people with heart failure may receive different medications.

Does this mean I have diabetes?

No.

Being prescribed an SGLT2 inhibitor does not necessarily mean you have diabetes.

Many people receive these medicines because they have heart failure and their healthcare provider believes the treatment may improve their health outcomes.

If you are unsure why a medication has been prescribed, ask your doctor or pharmacist to explain how it fits into your treatment plan.

Are there risks?

Like all prescription medicines, SGLT2 inhibitors can cause side effects.

Some of the more common side effects include dehydration, dizziness, urinary tract infections, and genital yeast infections. Rare but more serious side effects have also been reported.

Every medication involves balancing potential benefits against potential risks. Your healthcare provider considers your medical history and overall health before recommending any treatment.

Never stop or change a prescribed medication without speaking with your healthcare provider first.

Why this can be confusing

Many people assume a medicine is only used for the condition it was originally developed to treat.

In reality, this happens quite often.

Some blood pressure medicines are prescribed to protect the kidneys.

Certain antidepressants are used to manage chronic pain.

Aspirin has long been used to help reduce the risk of heart attacks and strokes in selected patients.

The use of diabetes medicines for heart failure is simply another example of how medical research continues to improve patient care.

The Bottom Line

If your doctor has prescribed a diabetes medication for heart failure, it does not automatically mean you have diabetes.

It reflects years of scientific research showing that certain SGLT2 inhibitors can provide important benefits for many people living with heart failure.

If you have questions about your treatment, speak with your doctor, cardiologist, or pharmacist. They are the best people to explain why a particular medication has been recommended for your individual health needs.
