Jardiance (empagliflozin) is a widely prescribed medication for type 2 diabetes. Men taking it face some unique risks alongside the common side effects.
Male patients are particularly susceptible to penile yeast infections and Fournier’s gangrene, a rare but serious bacterial infection affecting the genital and anal area. These risks are in addition to the standard side effects like urinary tract infections and increased urination.
Understanding these male-specific concerns helps patients and doctors make informed treatment decisions.
Most side effects are manageable and mild, but some require immediate medical attention. Jardiance works by filtering excess sugar through the kidneys into urine, which can create an environment where infections thrive.
From frequent bathroom trips to serious complications, here’s what male patients might experience. We’ll also cover medication interactions, warning signs, and when to contact your healthcare provider.
What Is Jardiance and How Does It Work?
Jardiance is an oral tablet prescribed for type 2 diabetes, heart failure, and chronic kidney disease. It contains empagliflozin, which lowers blood sugar by making your kidneys remove excess glucose through urine.
Active Ingredient: Empagliflozin
Empagliflozin is the active compound in Jardiance. The tablets come in 10 mg and 25 mg strengths, taken once daily.
This drug belongs to the SGLT-2 inhibitor class. These medications have transformed diabetes care because they work differently than older drugs.
Men take the same formulation as other patients. The tablets also contain inactive ingredients to help your body absorb the medication.
Approved Uses in Men
Jardiance treats several conditions in male patients. For type 2 diabetes, it helps manage blood sugar in men aged 10 and older when combined with diet and exercise.
It also reduces cardiovascular death and hospitalization risk in men with heart failure. Men with type 2 diabetes and established cardiovascular disease get added protection against heart-related death.
For chronic kidney disease, Jardiance helps men at risk of disease progression by reducing sustained decline in kidney function, lowering end-stage kidney disease risk, decreasing cardiovascular death risk, and reducing hospitalization rates.
Mechanism of Action
Empagliflozin blocks SGLT-2 proteins in your kidney tubules. These proteins normally reabsorb glucose from urine back into the bloodstream.
When Jardiance blocks them, glucose stays in the urine and leaves your body. This removes roughly 60 to 90 grams of glucose daily through urination.
For heart failure, the drug shifts the heart’s fuel use to a more balanced mix of fatty acids, ketone bodies, and amino acids. Jardiance also improves the heart’s diastolic function, helping it fill with blood more efficiently.
Most Common Side Effects of Jardiance in Males
Jardiance can cause several side effects in men. The most common are increased urination and thirst, genital yeast infections, urinary tract infections, and digestive symptoms like nausea.
Increased Urination and Thirst
Jardiance causes your kidneys to remove excess sugar through urine. This leads to frequent urination, a top complaint among male patients.
You may notice more bathroom visits during the day and night. Nocturia can disrupt sleep, and increased thirst is common as your body signals the need for more fluids.
Stay hydrated by drinking water regularly. Sipping throughout the day is more effective than drinking large amounts at once.
Genital Yeast Infections
Genital yeast infections can occur in men taking Jardiance, though less often than in women. The sugar-rich urine creates an environment where yeast thrives.
Uncircumcised men face a higher risk. Symptoms include redness, itching, swelling, pain around the penis, and possibly a strong-smelling discharge.
Watch for persistent itching, redness, swelling, white lumpy discharge, or discomfort during urination or sex. Contact your doctor if these symptoms appear.
Treatment usually involves antifungal creams or oral medications. Good hygiene—keeping the genital area clean and dry—can help prevent infections.
Urinary Tract Infections
Urinary tract infections (UTIs) are another common side effect. Jardiance increases the risk of UTIs, which can range from mild bladder infections to more serious kidney infections.
Excess glucose in urine allows bacteria to multiply in the urinary tract. Men may experience burning or painful urination, cloudy or bloody urine, and lower back or side pain.
Seek medical attention if you have fever with urinary symptoms, severe lower back pain, blood in urine, or persistent painful urination. Prompt evaluation is important, as UTIs can rarely progress to serious conditions like urosepsis.
Nausea and Digestive Symptoms
Nausea can occur, especially when starting Jardiance. This usually improves as your body adjusts.
Vomiting and diarrhea are less common but can lead to dehydration, especially combined with increased urination. If severe digestive symptoms persist, contact your doctor.
Serious and Rare Side Effects in Men
Most men tolerate Jardiance well, but some serious complications can occur. Risks include life-threatening metabolic changes, kidney damage, severe tissue infections, and allergic responses.
Diabetic Ketoacidosis (DKA)
Diabetic ketoacidosis is a dangerous complication that can occur even with normal blood sugar. The body breaks down fat too quickly, producing acidic ketones.
Warning signs include excessive thirst, frequent urination, nausea, vomiting, abdominal pain, shortness of breath, confusion, and fruity-smelling breath. Check both blood sugar and ketone levels regularly.
DKA requires emergency treatment. If symptoms appear, seek immediate medical care.
Acute Kidney Injury and Kidney Disease
Jardiance works through the kidneys, so kidney problems can develop. Acute kidney injury is more likely in men who are dehydrated, have existing kidney disease, or take certain medications.
Early kidney damage may show no symptoms. Watch for decreased urination, leg or ankle swelling, unusual tiredness, or confusion.
Doctors should monitor kidney function before and during treatment. Men with severe kidney disease or on dialysis should not take Jardiance.
If you experience dehydration symptoms like dizziness or fainting, drink fluids and contact your provider.
Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene)
Fournier’s gangrene is a rare but life-threatening infection linked to Jardiance in men. It rapidly destroys tissue in the genital and anal areas and can develop quickly after starting the medication.
Critical symptoms include fever, severe pain or swelling in the genital or anal area, foul odor, and crackling sounds when touching the area. This infection progresses rapidly and requires emergency surgical treatment and antibiotics.
If you develop these symptoms, seek emergency care immediately.
Severe Allergic Reactions
Serious allergic reactions to Jardiance are rare but possible. Angioedema causes rapid swelling around the face, lips, tongue, and throat.
Signs include difficulty breathing or swallowing, swelling of the face or throat, severe rash with hives, or rapid heartbeat. Stop taking Jardiance and call emergency services if these symptoms occur.
Even mild rashes or itching should prompt a call to your doctor. Anyone allergic to empagliflozin should avoid Jardiance.
Low Blood Sugar Risks in Males Taking Jardiance
Jardiance rarely causes low blood sugar on its own. However, when combined with insulin or sulfonylureas, hypoglycemia risk increases significantly.
Symptoms of Hypoglycemia
Low blood sugar symptoms include shakiness, sweating, rapid heartbeat, confusion, slurred speech, difficulty concentrating, blurred vision, and headaches.
Physical signs can also include cold sweats, sudden hunger, drowsiness, and lightheadedness. Fainting is a medical emergency.
Learn your personal hypoglycemia pattern and treat low blood sugar promptly to prevent severe symptoms.
Combined Use with Insulin or Other Diabetes Medications
Combining Jardiance with insulin creates the highest hypoglycemia risk. Insulin moves glucose into cells while Jardiance removes sugar through urine, increasing the risk of dangerous drops.
Sulfonylureas also raise this risk by forcing the pancreas to release more insulin. Males on combination therapy should monitor blood glucose more frequently.
Test before meals and at bedtime to identify patterns. Doctors may adjust doses when starting Jardiance. Always carry fast-acting glucose to treat low blood sugar quickly.
Dehydration, Blood Pressure, and Heart Health
Jardiance increases urination in men, which can trigger dehydration and low blood pressure. These effects are especially important for those with heart or kidney conditions.
Dehydration and Increased Urination
Jardiance works by preventing the kidneys from reabsorbing sugar into the bloodstream. This causes excess glucose, water, and sodium to be excreted in urine.
Men taking Jardiance often urinate more frequently. This fluid loss can lead to dehydration if not balanced by adequate water intake.
Signs of dehydration include lightheadedness, weakness, and darker urine. Men on diuretics face even higher dehydration risk, as both medications increase urination.
We recommend drinking at least eight 8-ounce glasses of water daily, though individual needs may vary. Severe dehydration may require hospitalization for intravenous fluids.
Actions to prevent dehydration:
- Increase water intake throughout the day
- Limit caffeinated beverages
- Reduce alcohol consumption
- Monitor urine color (pale yellow is best)
- Discuss diuretic dosage with your doctor
Low Blood Pressure and Dizziness
Increased urination from Jardiance can cause low blood pressure, especially when standing up quickly. This is known as orthostatic hypotension.
Symptoms include dizziness, weakness, or fainting when moving from sitting to standing. Reduced blood volume makes it harder for the body to maintain blood pressure.
Men on blood pressure medications are at higher risk. The combination with Jardiance can drop blood pressure too low.
Check your blood pressure regularly at home. Report readings consistently below 90/60 mmHg.
Warning signs needing immediate medical attention:
- Severe dizziness or fainting
- Rapid heartbeat
- Blurred vision
- Confusion
Your doctor may adjust medication doses to manage blood pressure changes.
Effects on Cardiovascular and Kidney Health
Jardiance reduces the risk of cardiovascular death in men with type 2 diabetes and heart disease. It also lowers hospitalization rates for heart failure.
For men with chronic kidney disease, Jardiance helps slow kidney function decline. The medication reduces strain on the kidneys by decreasing glucose processing.
Dehydration from Jardiance can temporarily stress the kidneys. Men with kidney problems need close monitoring, as severe dehydration can cause acute kidney damage.
Blood tests measuring creatinine help track kidney function during treatment. Men with heart failure must balance fluid intake—enough to prevent dehydration, but not so much that it worsens heart failure symptoms.
Consult your healthcare team about appropriate daily fluid limits.
Sex-Specific and Genital Side Effects for Men
Men taking Jardiance face unique risks of genital infections. Penile yeast infections are most common, while Fournier’s gangrene is a rare but serious complication.
Genital Yeast Infections in Males
Penile yeast infections occur more often in men on Jardiance due to higher glucose levels in urine. This creates an ideal environment for yeast growth around the genitals.
The infection typically affects the skin of the penis and nearby tissue. Uncircumcised men may experience higher rates due to the warm, moist environment under the foreskin.
Symptoms and Prevention Tips
Watch for redness or swelling of the penis, itching, foul-smelling discharge, rash, or pain during urination or sex.
Maintain good hygiene by washing and drying the genital area daily. Wear breathable cotton underwear and change out of wet clothing promptly.
If symptoms appear, contact your healthcare provider rather than self-treating.
Severe Infections and Complications
Fournier’s gangrene is a rare but life-threatening infection that destroys tissue around the genitals and anus. Symptoms include fever, severe pain, swelling, and a foul odor.
Some men may notice crackling or popping sounds when touching the area. This is a medical emergency and requires immediate attention.
Other serious infections include kidney infections and urosepsis. These require urgent medical care and may mean stopping Jardiance.
Drug Interactions, Precautions, and Contraindications
Jardiance can interact with several medications, especially those affecting blood sugar and fluid balance. Certain conditions and life stages require careful consideration before starting treatment.
Interactions with Other Diabetes Medications
Combining Jardiance with insulin or medications that stimulate insulin release increases the risk of hypoglycemia. These include sulfonylureas like glipizide and glyburide, and glinides such as repaglinide.
Blood sugar can drop too low with these combinations. Insulin or sulfonylurea doses may need reduction.
Men using these medications should monitor blood glucose more frequently. Symptoms of low blood sugar include shakiness, sweating, confusion, and rapid heartbeat.
Other Common Drug Interactions
Diuretics combined with Jardiance can cause excessive fluid loss and dehydration. This amplifies the risk of low blood pressure and kidney issues.
Lithium levels can rise dangerously when taken with Jardiance. Frequent monitoring is needed, as toxicity can cause tremors, confusion, and irregular heart rhythms.
Jardiance may increase LDL cholesterol. Men on cholesterol medications should have lipid panels checked regularly.
Who Should Avoid Jardiance?
Men with severe kidney disease (eGFR below 30 mL/min/1.73 m²) should not take Jardiance. The drug is ineffective and potentially harmful at this level.
Those on dialysis or with a history of serious allergic reactions to empagliflozin should avoid Jardiance. It is not recommended during pregnancy or for men planning to father children without proper counseling.
Jardiance passes into breast milk, so breastfeeding fathers should discuss alternatives. Men prone to recurrent genital infections or with a history of bladder cancer require extra monitoring.
Monitoring, Blood Tests, and When to Consult a Doctor
Regular monitoring helps catch complications early when taking Jardiance. Men need specific blood tests to track kidney function, blood sugar, and other important markers.
Essential Lab Tests for Men Using Jardiance
Doctors will order kidney function tests before and during treatment. These measure serum creatinine and eGFR to detect changes in kidney filtration.
Men with chronic kidney disease need more frequent monitoring. Blood sugar testing is critical, especially if taking Jardiance with insulin or other diabetes drugs.
Check glucose as directed to prevent hypoglycemia. Symptoms include shakiness, confusion, rapid heartbeat, blurred vision, and cold sweats.
Key lab tests include:
- Kidney function panels (creatinine, eGFR)
- Fasting blood glucose and HbA1c
- Blood pressure checks
- Cholesterol and lipid profiles
- Hematocrit levels
Doctors may also monitor ketones if you experience nausea or vomiting, as Jardiance can cause diabetic ketoacidosis even with normal blood sugar.
When to Seek Medical Attention
Contact your doctor immediately if you notice pain, tenderness, or sores on your legs or feet. Jardiance increases the risk of lower limb amputation in some men.
Red, swollen, or painful genital areas may indicate a yeast infection or the rare but serious Fournier’s gangrene. Seek emergency care for severe symptoms.
Severe symptoms include difficulty breathing, signs of severe dehydration such as extreme thirst, dizziness, or decreased urination, and symptoms of ketoacidosis like nausea, vomiting, or abdominal pain. Allergic reactions such as facial swelling or hives require immediate medical attention.
Men experiencing painful urination, bloody urine, or fever should call their doctor right away. These symptoms could signal a urinary tract or kidney infection.
Other side effects that warrant medical consultation include persistent nausea, ongoing diarrhea, or fainting spells.
