Understanding Gout and Uric Acid
Gout is an inflammatory arthritis caused by urate crystal accumulation in joints, often the big toe, leading to pain and swelling. These crystals form from high blood uric acid (hyperuricemia). Uric acid is a purine breakdown product, and gout occurs when the kidneys don't excr ete enough or the body makes too much.
The Valsartan Connection to Gout
Valsartan is an Angiotensin II Receptor Blocker (ARB) that lowers blood pressure by relaxing blood vessels. While ARBs are generally safe, their effect on uric acid varies. Valsartan can have a neutral or negative impact on serum uric acid, potentially increasing levels. One study showed valsartan significantly increased uric acid compared to losartan. Elevated uric acid increases the risk of acute gout attacks.
Combination Medications and Increased Risk
Valsartan is often combined with diuretics like hydrochlorothiazide (HCTZ). HCTZ is known to increase uric acid by reducing kidney excretion. Combining valsartan and HCTZ significantly increases the risk of developing or worsening gout.
Comparing Valsartan and Other ARBs
Losartan, another ARB, differs from valsartan. It is a weak uricosuric agent, meaning it helps the kidneys exc rete uric acid. This makes losartan a preferred option for hypertensive patients with hyperuricemia or gout.

Managing Gout While on Valsartan
Managing gout risk on valsartan involves medical supervision and lifestyle adjustments.
Discuss Medication Alternatives
Consult your doctor to review your treatment. If you have a history of gout, alternatives like losartan or some calcium channel blockers may be considered. Do not stop valsartan without medical advice.
Lifestyle and Dietary Changes
Lifestyle modifications are crucial for controlling gout:
- Diet: Eat vegetables, fruits, whole grains, and low-fat dairy. Limit high-purine foods (red meat, organ meats, certain seafood) and high-fructose corn syrup.
- Hydration: Drink plenty of water to help kidneys exc rete uric acid.
- Alcohol: Reduce or avoid alcohol, especially beer and hard liquor.
- Weight: Achieve a healthy weight; avoid crash dieting.
- Exercise: Engage in regular, moderate exercise.
Conclusion
Valsartan can increase serum uric acid levels and potentially lead to gout attacks, particularly in combination with HCTZ. Losartan is an alternative ARB that may be preferable for patients with gout or hyperuricemia due to its uric acid-lowering effect. Managing gout risk while on or switching from valsartan requires working with a healthcare provider and implementing lifestyle changes. For dietary guidance, resources like Healthline's gout-friendly diet guide are available.
What to Do If You Suspect Gout on Valsartan
If you experience symptoms of a gout attack (pain, swelling, redness), contact your doctor immediately. Do not stop valsartan without medical approval. Your doctor can measure uric acid and recommend treatment or medication adjustments.
Additional Considerations for Patients
Patient factors like kidney disease or diabetes can increase gout risk with valsartan. Regular monitoring of kidney function and electrolytes is important. The medication's specific formulation, such as a combination with amlodipine, may also affect uric acid levels. Personalized medical advice based on your health history is essential.
