Why this medication is prescribed
Potassium and magnesium supplements replace these
minerals, which can be lost because of increased urination when taking diuretics.
When to take
Take medications right after meals or with food.
Follow the label directions on how often to take. The number of doses you take
each day, the time allowed between doses, and how long you need to take it will
depend on the type of medication prescribed, as well as your condition.
Food and drug interactions
If you are using a salt substitute, tell your doctor
or nurse. Many salt substitutes contain potassium. Follow your doctor’s dietary
guidelines for including potassium-rich foods in your diet.
Your doctor will consider the other heart failure
medications you are taking, such as ACE inhibitors, aldosterone antagonists, and
certain diuretics, when determining your potassium dosage.
