Jardiance can cause fatigue in some patients, but tiredness is not a universal side effect.
Understanding Jardiance and Its Effects on Energy Levels
Jardiance, known generically as empagliflozin, is a prescription medication primarily used to manage type 2 diabetes. It belongs to a class of drugs called SGLT2 inhibitors, which work by helping the kidneys remove excess glucose through urine. This process helps lower blood sugar levels and reduces the risk of complications linked to diabetes.
Because Jardiance influences blood sugar and kidney function, it can affect energy levels in various ways. Some patients report feeling tired or fatigued after starting the medication, while others experience no change or even improved energy. Understanding why this happens requires looking at how Jardiance interacts with the body’s systems.
How Jardiance Works and Its Impact on Fatigue
By blocking the sodium-glucose co-transporter 2 (SGLT2) in the kidneys, Jardiance prevents glucose from being reabsorbed into the bloodstream. Instead, glucose is excreted through urine. This mechanism helps lower blood sugar but also causes some loss of calories and water through increased urination.
This loss of calories can lead to weight reduction over time, which many patients find beneficial. However, it may also temporarily reduce energy availability, especially during the initial weeks of treatment. The increased urination can cause dehydration if fluid intake isn’t sufficient, leading to symptoms like dizziness and tiredness.
Additionally, when blood sugar levels drop too low or fluctuate rapidly—a condition known as hypoglycemia—fatigue is a common symptom. Although Jardiance alone rarely causes hypoglycemia, combining it with other diabetes medications like insulin or sulfonylureas can increase this risk.
Common Side Effects of Jardiance Related to Fatigue
Fatigue isn’t listed as one of the most common side effects of Jardiance in clinical trials; however, it does appear among less frequent complaints. Here are some side effects that could contribute indirectly to feeling tired:
- Dehydration: Increased urination may lead to dehydration if fluid intake isn’t adequate.
- Low Blood Pressure: Jardiance can cause mild drops in blood pressure due to fluid loss, leading to dizziness and weakness.
- Low Blood Sugar: Particularly when combined with other diabetes drugs.
- Ketoacidosis: Though rare, this serious condition involves elevated ketone bodies causing fatigue among other symptoms.
Each of these factors can sap your energy and make you feel more tired than usual.
The Role of Dehydration in Tiredness
Because Jardiance increases urine output (a process called osmotic diuresis), it’s easy for patients not to drink enough fluids to compensate for this loss. Even mild dehydration can cause fatigue, headaches, and difficulty concentrating.
Drinking plenty of water throughout the day helps maintain hydration levels and reduces these symptoms. If you notice increased thirst or dark-colored urine while taking Jardiance, these might be signs you need more fluids.
Blood Sugar Fluctuations and Fatigue
Blood sugar swings can directly impact energy levels. When blood sugar drops too low (hypoglycemia), your body doesn’t have enough fuel for cells to function properly. This leads to symptoms like shakiness, sweating, confusion—and yes—tiredness.
Jardiance itself has a lower risk of causing hypoglycemia compared to older diabetes medications because it works by removing excess glucose rather than increasing insulin production. Still, if combined with insulin or sulfonylureas, monitoring for hypoglycemia is essential.
Clinical Data: Fatigue Reports in Patients Taking Jardiance
Clinical trials provide valuable information about how often patients experience side effects like fatigue when using Jardiance. Below is a table summarizing relevant data from key studies:
| Study Name | Total Patients | % Reporting Fatigue/Tiredness |
|---|---|---|
| EMPA-REG OUTCOME (2015) | 7,020 | 1.5% |
| EMPA-REG MONO (2014) | 154 | 2% |
| Pooled Phase III Trials | 4,500+ | 1-3% |
While fatigue was not a leading complaint in these studies, a small percentage did report feeling tired or weak during treatment. This aligns with clinical observations that fatigue may be an occasional but not predominant side effect.
The Connection Between Jardiance and Ketoacidosis-Related Fatigue
Though rare—occurring in less than 0.1% of users—euglycemic diabetic ketoacidosis (DKA) is a serious adverse event linked with SGLT2 inhibitors like Jardiance. DKA happens when ketones build up in the bloodstream due to insufficient insulin activity despite normal or mildly elevated blood sugar levels.
Fatigue is one of several symptoms associated with ketoacidosis along with nausea, vomiting, abdominal pain, difficulty breathing, and confusion. Patients experiencing unexplained tiredness alongside these signs should seek immediate medical attention.
Understanding this risk underscores why monitoring symptoms closely during treatment initiation or periods of illness is vital.
Avoiding Ketoacidosis While on Jardiance
To minimize DKA risk:
- Avoid excessive alcohol consumption.
- Do not skip meals or drastically reduce carbohydrate intake without medical advice.
- If feeling unwell with symptoms like nausea or vomiting while on Jardiance, contact your healthcare provider immediately.
Prompt action can prevent serious complications including prolonged fatigue due to metabolic imbalance.
Lifestyle Factors That Influence Fatigue While Taking Jardiance
Fatigue doesn’t happen in isolation; lifestyle choices play a big role in how you feel day-to-day while on any medication including Jardiance.
Dietary Considerations
Since Jardiance promotes glucose loss via urine—which means fewer calories—you might feel less energetic if your diet doesn’t compensate adequately for this loss. Eating balanced meals rich in complex carbohydrates and proteins supports steady energy release throughout the day.
Avoiding excessive sugars helps prevent spikes and crashes that worsen fatigue symptoms.
Hydration Habits
As mentioned earlier, staying well hydrated combats dehydration-related tiredness caused by increased urination on Jardiance. Carrying a water bottle and sipping regularly throughout the day keeps you alert and focused.
Physical Activity Levels
Regular exercise boosts overall energy by improving cardiovascular health and muscle strength. However, starting intense workouts abruptly after beginning Jardiance might increase fatigue temporarily as your body adjusts.
Gradual increases in activity paired with proper nutrition help maintain stamina without overwhelming your system.
Troubleshooting Fatigue While Using Jardiance
If you notice persistent tiredness after starting Jardiance:
- Track Your Symptoms: Keep a diary noting when fatigue occurs relative to medication timing.
- Check Hydration: Increase water intake if you suspect dehydration.
- Review Other Medications: Some drugs combined with Jardiance may increase fatigue risk.
- Consult Your Doctor: Rule out other causes such as anemia or thyroid problems which also cause tiredness.
Sometimes adjusting dosage or timing under medical supervision improves side effects without sacrificing diabetes control.
