Valsartan is a medication frequently prescribed to manage high blood pressure and certain heart conditions. Many individuals taking this prescription medication wonder about its potential side effects, particularly if it might lead to feelings of tiredness. This article addresses the relationship between valsartan and fatigue, providing insights into why it might occur and what steps can be taken.
Is Tiredness a Side Effect?
Fatigue is a recognized side effect of valsartan. While not universally experienced, it is listed among common effects. In clinical trials for hypertension, fatigue was reported by approximately 2% of patients taking valsartan, compared to 1% in the placebo group.
Valsartan belongs to a class of drugs called Angiotensin Receptor Blockers (ARBs). Other common side effects include dizziness and headache, which can sometimes contribute to a feeling of overall weariness. Typically, any initial fatigue is mild and may lessen as the body adjusts to the medication.
Why Valsartan Might Cause Fatigue
Valsartan’s primary action involves lowering blood pressure, and this effect is often linked to the experience of fatigue. The medication works by blocking the action of angiotensin II, a hormone that naturally constricts blood vessels and raises blood pressure. By preventing angiotensin II from binding to its receptors, valsartan allows blood vessels to relax and widen. This therapeutic lowering of blood pressure can sometimes lead to what is known as hypotension.
When blood pressure drops excessively, or even if it drops to a level lower than an individual’s usual baseline, it can reduce blood flow to the brain and muscles. This decreased perfusion can result in symptoms such as dizziness, lightheadedness, and a general feeling of fatigue. Individual sensitivity to changes in blood pressure varies, meaning some people may feel these effects more acutely than others. Valsartan aims to achieve a healthy blood pressure level, but the body’s adjustment to this new state can manifest as tiredness.
What to Do About Fatigue
If you are experiencing fatigue while taking valsartan, communicate this to your healthcare provider. Never stop or adjust your medication dosage without first consulting your doctor. Your doctor can evaluate your symptoms, determine if the fatigue is related to valsartan, and rule out other potential causes. They may consider adjusting your dosage or exploring alternative medications.
Monitoring your blood pressure at home, if recommended by your doctor, can also provide valuable information about how the medication is affecting you. Beyond medication adjustments, certain lifestyle practices can help manage overall energy levels. Maintaining adequate hydration by drinking enough fluids throughout the day can help mitigate dizziness and fatigue. Eating a balanced diet and ensuring sufficient sleep are also important factors that contribute to overall well-being and can help combat feelings of tiredness.
