What might be a side effect of taking digoxin?

Fatigue is a known side effect of taking digoxin, which is a medication commonly used to treat certain heart conditions, such as atrial fibrillation and heart failure. Digoxin works by increasing the force of heart contractions and slowing down heart rate, which can sometimes result in feelings of tiredness or fatigue. This occurs because the medication alters the heart’s workload and can affect overall energy levels in some patients.

In contrast, the other options provided do not align with common side effects of digoxin. Increased appetite and heightened energy levels are not typical effects of digoxin and may signify other health issues or reactions to other substances rather than the medication itself. Reduced stress is also not a direct side effect of digoxin; while managing heart conditions may contribute to a sense of well-being, it is not an intended effect of the drug. Understanding medication side effects is crucial for monitoring and managing patient outcomes effectively.
