Potassium chloride with digoxin can make the potassium in your blood too high. Other medicines that raise this risk include some blood pressure medicines, cyclosporin, NSAID painkillers, beta-blockers, heparin and potassium-sparing water tablets.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
What to do: Ask your doctor or pharmacist before using these together. They may check you more closely or change your plan.
