There are substantial risks associated with solid potassium formulations. Medications like Micro-K may cause ulceration, bleeding, perforation or obstruction of the esophagus or digestive tract.
Contact your physician immediately if you think a pill has become stuck in your throat or if you experience stomach pain, vomiting or notice black or tarry stools.
Other adverse reactions associated with such potassium supplements include nausea, loss of appetite, and diarrhea. Report any such symptoms promptly.
Micro-K can interact with a number of other medications.
Blood pressure drugs such as Accupril, Altace, Capoten, Vasotec, Prinivil or Zestril can raise potassium to dangerous levels in combination with Micro-K.
The same thing could occur with potassium-based salt substitutes and potassium-sparing diuretics such as Aldactone, Dyazide, Dyrenium, Midamor or Moduretic.
Check with your doctor and pharmacist to make sure Micro-K is safe in combination with any other drugs you take.
