                • Signs of stomach bleeding - bloody/tarry stools, vomiting blood or coffee ground-like vomit
                • Allergic reaction - hives, swelling of face/lips/tongue/throat, difficulty breathing
                • Muscle weakness, numbness/tingling in hands/feet/mouth, uneven heartbeat
                  The risk of side effects, especially serious ones, increases with higher dosages of potassium chloride. Certain medical conditions like kidney disease, dehydration, and gastrointestinal issues may also increase the risk of side effects.

                    Potassium chloride and other drugs

                    some important medical interactions to be aware of when taking potassium chloride:

                    Interactions with Medications

                    • Potassium-sparing diuretics (e.g. spironolactone, amiloride, triamterene): These medications can increase potassium levels and should not be taken concurrently with potassium chloride supplements, as it can lead to dangerous hyperkalemia (high potassium levels).
                    • ACE inhibitors (e.g. lisinopril, enalapril): These blood pressure medications can increase potassium retention and levels. Potassium chloride should be used cautiously when combined with ACE inhibitors.
                    • Angiotensin II receptor blockers (ARBs) (e.g. losartan, valsartan): Similar to ACE inhibitors, ARBs can increase serum potassium levels when combined with potassium supplements.
                    • Non-potassium-sparing diuretics (e.g. furosemide, hydrochlorothiazide): These can increase potassium excretion and may necessitate potassium supplementation with potassium chloride.
                    • Digoxin: Potassium levels can affect the therapeutic and toxic effects of this heart medication. Potassium chloride should be used cautiously with digoxin.

                    Interactions with Medical Conditions

                    • Kidney disease: Impaired kidney function reduces potassium excretion, increasing the risk of hyperkalemia when taking potassium chloride.
                    • Dehydration: Low fluid levels concentrate potassium in the blood, raising the risk of hyperkalemia with potassium supplements.
                    • Gastrointestinal issues (vomiting, diarrhea): These can lead to potassium depletion, necessitating potassium chloride supplementation.
                    • Diabetes: Certain diabetes medications like insulin can shift potassium into cells, increasing the risk of hypokalemia.

                    It is crucial to inform your healthcare provider about all medications, supplements, and medical conditions before starting potassium chloride to prevent potentially dangerous interactions and adverse effects.
