There aren’t any known interactions between eating salt and taking Aldactone. However, some of the conditions Aldactone is used to treat are affected by how much salt you eat. Even though salt doesn’t interact with Aldactone, you should still talk with your doctor about how much salt is safe for you to consume.
While taking Aldactone, you should avoid foods that contain high levels of potassium. This includes many salt substitutes, which often contain potassium chloride.
Aldactone causes your body to hold on to potassium in the kidneys. Consuming high amounts of potassium while you take Aldactone could lead to hyperkalemia. This is a high level of potassium in your blood.
If you have more questions about salt or salt substitutes and Aldactone, talk with your doctor.
