While taking azilsartan and chlorthalidone, it's advisable to monitor dietary intake of potassium. Chlorthalidone can cause the body to lose potassium, so incorporating potassium-rich foods like bananas, oranges, and spinach may be beneficial. However, azilsartan can increase potassium levels, so it's important to balance intake and avoid potassium supplements or salt substitutes containing potassium without consulting a healthcare provider. Additionally, reducing sodium intake can enhance the medication's effectiveness in lowering blood pressure.
