5 WARNINGS AND PRECAUTIONS Gastrointestinal Irritation: Take with meals. ( 5.1 ) 5.1 Gastrointestinal Adverse Reactions Solid oral dosage forms of potassium chloride can produce ulcerative and/or stenotic lesions of the gastrointestinal tract, particularly if the drug maintains contact with the gastrointestinal mucosa for prolonged periods. Consider the use of liquid potassium in patients with dysphagia, swallowing disorders, or severe gastrointestinal motility disorders. If severe vomiting, abdominal pain, distention, or gastrointestinal bleeding occurs, discontinue Klor-Con extended-release tablets and consider possibility of ulceration, obstruction or perforation. Klor-Con extended-release tablets should not be taken on an empty stomach because of its potential for gastric irritation [see Dosage and Administration (2.1) ] .
