Exams and Tests
Sometimes the cause of low potassium is not clear. Your doctor may perform certain tests to rule out other conditions such as renal tubular acidosis, Cushing syndrome, and hypocalcemia.
- Blood tests will check kidney function (BUN and creatinine), glucose, magnesium, calcium, and phosphorous if an electrolyte imbalance is suspected. Because low potassium is known to affect heart rhythms (arrhythmias), your doctor may order a digoxin (Lanoxin) level if you are taking a digitalis preparation.
- ECG or a heart tracing is done to detect electrical changes in the heart and certain types of irregular heart rhythms that may be caused by low potassium.

Important Safety Information
- KAPIDEX may not be right for everyone. You should not take KAPIDEX if you are allergic to KAPIDEX or any of its ingredients. Severe allergic reactions have been reported.
- Symptom relief does not rule out other serious stomach conditions.
- The most common side effects of KAPIDEX were diarrhea (4.8%), stomach pain (4.0%), nausea (2.9%), common cold (1.9%), vomiting (1.6%), and gas (1.6%). 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.
