Potassium is a mineral that is found naturally in foods and is necessary for many normal functions of your body, especially the beating of your heart.

Potassium bicarbonate is used to prevent or to treat a potassium deficiency (hypokalemia).

Potassium bicarbonate may also be used for other purposes not listed in this medication guide.

Avoid taking potassium supplements or using other products that contain potassium without first asking your doctor. Salt substitutes or low-salt dietary products often contain potassium. If you take certain products together you may accidentally get too much potassium. Read the label of any other medicine you are using to see if it contains potassium.

There are many other medicines that can interact with potassium bicarbonate. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor. Keep a list with you of all the medicines you use and show this list to any doctor or other healthcare provider who treats you.
