How Jardiance Works
Jardiance is a sodium-glucose co-transporter 2 (SGLT2) inhibitor. These medications may help lower blood sugar by reducing the reabsorption of sugar in the kidneys, which is then excreted in the urine.
In other words, imagine your kidneys are like a train station where sugar is being loaded back onto trains to go back into your bloodstream. Normally, there's a gatekeeper called SGLT2 that helps put the sugar back on the train.
Empagliflozin acts like a lock on that gate, inhibiting the sugar from getting back on board. Instead, the sugar is redirected out of your body through urine, which helps lower blood sugar levels.
Benefits of Jardiance
- The primary benefit of Jardiance is improved blood sugar control in those with type 2 diabetes (T2DM).
- Additionally, clinical trials suggest that Jardiance may reduce the risk of certain major cardiovascular events, such as heart attacks or strokes, in adults with established heart disease, including those without diabetes.
- Studies have demonstrated renal protective benefits, weight, and blood pressure reduction, as well as potential anti-inflammatory and oxidative stress reduction, which may contribute to cognitive benefits
Common Side Effects of Jardiance
Some individuals may experience gastrointestinal (GI) symptoms, which are often mild and may resolve as the body adjusts to the medication.
Additionally, Jardiance can potentially increase the risk of UTIs and genital yeast infections, particularly in women. Men are also prone to fungal infections. These infections are associated with increased sugar levels in the urine.
Digestive Issues
- Nausea: Shifts in electrolyte and fluid balance caused by increased sugar in the urine may potentially contribute to an upset stomach.
- Diarrhea: Changes in glucose levels in the GI tract could affect gut microbiota, which may manifest as diarrhea.
- Constipation: Increased excretion of glucose and sodium in the urine can lead to dehydration and reduced fluid in the intestines, possibly leading to constipation.
UTIs
- Bacterial Infection: Use of Jardiance is associated with an increased risk of bacterial UTIs, though severe infections requiring hospitalization were rare.
- Yeast/Fungal Infection: Genital yeast and fungal infections are more frequent with Jardiance use when compared to placebo, though they are often mild and managed with standard therapy.
Other Common Side Effects
- Increased Urination: Increases in urinary glucose excretion cause an increase in urine volume.
- Dehydration: Increased urination can lead to increased fluid loss and dehydration.
- Dizziness: Decreases in blood pressure can lead to lightheadedness, especially in patients prone to orthostatic hypotension.
Serious Side Effects of Jardiance
While rare, some side effects are severe and require immediate medical attention.
- Ketoacidosis: Ketoacidosis Ketoacidosis is a serious condition involving a buildup of acids (ketones) in the blood, which may occur when the body breaks down fat instead of glucose for energy. Early symptoms include nausea/vomiting, abdominal pain, difficulty breathing. Other symptoms to watch out for include fruity breath, extreme thirst, confusion, and fatigue.
- Kidney Damage: Jardiance may exacerbate kidney problems, especially in individuals with pre-existing kidney disease. Signs to watch for include swelling in the lower extremities and reduced urine output.
- Amputation Risk: Some studies have shown a potential for an increased risk of lower limb amputations in patients taking SGLT2 inhibitors. Although the risk remains under study, individuals with a history of vascular issues or diabetic foot problems should discuss this potential risk with their healthcare provider.
Risk Factors for Severe Side Effects
Certain individuals may be more prone to severe side effects:
- Individuals with Kidney Disease: Pre-existing kidney problems increase the risk of kidney damage, even though empagliflozin may slow the progression of kidney function decline. Individuals with impaired kidney function may require closer monitoring by a healthcare provider.
- Elderly Patients: Elderly individuals are at a greater risk for dehydration and low blood pressure, likely due to the diuretic effect of SGLT2s. Monitoring hydration and blood pressure is important.
- Patients Prone to Dehydration: Patients with underlying conditions, such as diarrhea, high fluid loss, and excessive sweating, should be monitored for signs and symptoms of dehydration.
Drug Interactions
Several medication classes can increase the risk of side effects:
- Diuretics: Also known as “water pills," the diuretic effects of empagliflozin can enhance the fluid-depleting effects of other diuretics, increasing risks of dehydration and low blood pressure.
- Blood Pressure Medications: Empagliflozin lowers blood pressure, and its effects can be additive when combined with ACE inhibitors or ARBs. Patients taking these medications should monitor their blood pressure.
- Insulin/Diabetes Medications: When taken with insulin or sulfonylureas, SGLT2s have been shown to increase low blood sugar risk. These medications work in different ways, and their effects can be additive as well.
Individuals taking these medications are advised to consult their healthcare provider to discuss potential interactions.
Managing Side Effects
- Regular Checkups: Routine kidney function tests and monitoring blood sugar levels can help catch any potential complications early.
- Hydration: Patients should be encouraged to drink plenty of fluids to counteract increased urination and to prevent dehydration.
Lifestyle Adjustments
- Diet: A balanced diet rich in fiber can help manage GI side effects.
- Exercise: Moderate physical activity combined with empagliflozin can support overall well-being, but should be tailored to each patient’s capabilities.
When to Contact a Healthcare Provider
Patients should seek immediate medical attention if they experience:
- Difficulty Breathing/Severe Abdominal Pain: These are potential symptoms of ketoacidosis. Additional early signs include nausea and vomiting.
- Swelling/Reduced Urine Output: These are symptoms of potential kidney issues.
- Unusual Pain/Sores in Lower Limbs: These are symptoms of potential risks for amputation. While empagliflozin itself doesn’t have a strong association, other SGLT2 inhibitors have shown risks, and this side effect should be monitored.
Healthcare providers can explain symptoms and strategies to help manage serious side effects, emphasizing the importance of prompt reporting. Open communication is key to early intervention and critical in minimizing risks.
Alternative Medications to Jardiance
The following medications may be used as alternatives to Jardiance under some circumstances. All medications should be discussed with a healthcare provider who can individualize medications based on an individual's unique medical history.
Other SGLT2 Inhibitors
- Canagliflozin (Invokana): Evidence suggests that canagliflozin may contribute to reductions in HbA1c levels and weight loss, though it has been associated with a potential increased risk of amputation and euglycemic (normal blood sugar levels) ketoacidosis.
- Dapagliflozin (Farxiga): Studies show that dapagliflozin is highly effective at managing high blood sugar and has added cardiovascular and renal protection benefits.
Non-SGLT2 Inhibitor Medications
- Metformin: Metformin is still the first-line treatment for T2DM, especially for patients without advanced cardiovascular or renal complications. It is well-tolerated and cost-effective.
- Sulfonylureas: Medications such as glimepiride and glipizide are effective for lowering blood sugars but carry risks of hypoglycemia and weight gain. These medications are typically considered when there are other limiting factors.
- DPP-4 Inhibitors: Medications such as sitagliptin and linagliptin are effective and well-tolerated, making them suitable for elderly patients or those with mild renal impairment. They are less effective for weight loss but have fewer GI side effects when compared to GLP-1 receptor agonists.
- GLP-1 Receptor Agonists: Drugs such as liraglutide and semaglutide are highly effective at lowering blood sugar and provide additional benefits, including weight loss and cardiovascular protection. These are preferred medications in those with ASCVD risks or obesity.
