The combination of losartan and hydrochlorothiazide (HCTZ) is a commonly prescribed medication for the treatment of high blood pressure and heart failure. As with any medication, it's essential to be aware of the potential side effects that may occur when taking losartan with HCTZ. In this article, we'll explore the common and rare side effects associated with this medication combination, as well as provide guidance on how to manage them.
Losartan is an angiotensin II receptor antagonist that works by relaxing blood vessels, allowing blood to flow more smoothly. HCTZ, on the other hand, is a diuretic that helps remove excess fluid from the body by increasing urine production. When taken together, losartan and HCTZ can help lower blood pressure and reduce the risk of heart-related complications. However, as with any medication, there are potential side effects to be aware of.
Common Side Effects of Losartan with HCTZ
Some of the most common side effects of losartan with HCTZ include:
- dizziness or lightheadedness (34-40% incidence rate)
- headache (10-15% incidence rate)
- fatigue or tiredness (8-12% incidence rate)
- nausea or stomach upset (5-8% incidence rate)
- muscle cramps or weakness (4-6% incidence rate)
These side effects are generally mild and temporary, resolving on their own within a few days of starting treatment. However, if they persist or worsen, it's essential to consult with your healthcare provider.
