Diuretics: Management Tips and Common Side Effects
Sometimes a diuretic causes people to lose potassium. Potassium is needed for the body to work properly and to ensure that your heart rhythm is okay. Often, patients taking a diuretic need to take potassium pills, too.
If you are taking a diuretic, your blood should be checked periodically to make sure that your potassium level is normal.
Diuretics can also cause people to lose too much fluid, so that they become dehydrated. If you feel dizzy, call your doctor or nurse. While taking a diuretic it is a good idea to weigh yourself daily and go over your weight log (Module 4) with your doctor or nurse to make sure you are not losing too much fluid.
