Eating foods containing potassium may help prevent significant potassium loss. You can prevent potassium loss by taking a liquid or tablet that has potassium along with the diuretic, if your doctor recommends it. They don't cause the body to lose potassium. They might be prescribed alone but are usually used with another diuretic. Some of these combinations are Aldactazide, Dyazide, Maxzide or Moduretic.
Some people suffer from attacks of gout after prolonged treatment with diuretics.
This side effect isn't common and can be managed by other treatment. In people with diabetes, diuretic drugs may increase the blood sugar level. A change in drug, diet, insulin or oral antidiabetic dosage corrects this in most cases. Your doctor can change your treatment. Most of the time the degree of increase in blood sugar isn't much.
