Low Potassium Causes
Low potassium can occur for many reasons. Use of water pills (diuretics), diarrhea, and chronic laxative abuse are the most common causes of low potassium.
Illness and other medications may also lower potassium levels. Other causes include:
Kidney losses
- Certain kidney disorders such as renal tubular
acidosis (for example,
chronic kidney failure and
acute kidney failure)
- Magnesium deficiency
- Leukemia
Loss of potassium through stomach and intestines
Effect of medicines
- Water pills (diuretics)
- Medicines used for asthma or emphysema
(beta-adrenergic agonist type of drugs such as bronchodilators, steroids, or
theophylline)
- Aminoglycosides (a type of antibiotic used for treating certain serious infections)
Shifting of potassium across cells can lower the concentration of potassium measured in the blood.
Decreased food intake or malnutrition

KAPIDEX and certain other medicines can affect each other. Before taking KAPIDEX, tell your doctor if you are taking ampicillin, atazanavir, digoxin, iron, ketoconazole, or tacrolimus. If you are taking KAPIDEX with warfarin, you may need to be monitored because serious risks could occur.
Uses of KAPIDEX
- Persistent heartburn two or more days a week, despite treatment and diet changes, could be acid reflux disease (ARD). Prescription KAPIDEX capsules are used in adults to treat heartburn related to ARD, to heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE), and to stop EE from coming back. Individual results may vary. Most damage (erosions) heals in 4–8 weeks.
