Potassium chloride is a prescription medication used to treat and prevent low potassium levels due to poor dietary intake, certain diseases, or other drugs. Potassium chloride belongs to a group of drugs called electrolytes, which are compounds that help the body function normally.

This medication comes in tablet and capsule forms and may be taken multiple times a day with food and water.

This medication is also available in an injectable form to be given directly into a vein by a healthcare professional.

Common side effects of potassium chloride include nausea, vomiting, stomach discomfort or pain, and diarrhea.

Potassium chloride is a prescription medication used to treat and prevent low potassium levels due to poor dietary intake, certain diseases, or other drugs.

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

Take potassium chloride exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

Dose amount is determined according to the individual needs of each patient:

• For the prevention of hypokalemia: typically in the range of 20 mEq per day
• For treatment of potassium depletion: typically in the range of 40-100 mEq per day or more

Dosage should be divided if more than 20 mEq per day. No more than 20 mEq is given in a single dose.

Serious side effects have been reported with potassium chloride including:

• Hyperkalemia. Potassium chloride can lead to dangerously high levels of potassium, which could cause the heart to stop beating. Tell your doctor if you have a history of heart or kidney disease.
• Digestive tract injury. Potassium chloride can remain in the digestive system for too long, leading to injuries in the digestive tract (stomach, intestines). Tell your healthcare provider right away if you have some or all of the following symptoms of digestive tract injury:
  • stomach pain
  • swollen stomach
  • dark or black stools
• Metabolic acidosis (too much acid in the body). Patients should be treated with a particular potassium salt such as potassium bicarbonate, potassium citrate, potassium acetate, or potassium gluconate. Use with potassium chloride is not recommended.

Do not take potassium chloride if you:

• have high potassium levels (hyperkalemia)
• have any physical, disease-related, or drug-related problems that would stop or slow the passage of this medication through the gastrointestinal (stomach and intestines) tract
• have an enlargened heart that narrows the esophagus; a liquid form of this medication should be prescribed instead of the capsule or tablet

Serious side effects have been reported with potassium chloride. See “Drug Precautions” section.

Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements. Especially tell your doctor if you take:

• potassium-sparing diuretics such as amiloride (Midamor), triamterene (Dyrenium), and spironolactone (Aldactone)
• ACE inhibitors such as enalopril (Vasotec) and lisinopril (Prinivil, Zestril)
• vitamins containing potassium

This is not a complete list of potassium chloride drug interactions. Ask your doctor or pharmacist for more information.

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Potassium chloride falls into category C. This medication may be given to a pregnant woman if her healthcare provider believes that its benefits to the pregnant woman outweigh any possible risks to her unborn baby.

It is not known if potassium chloride will harm your unborn baby.

Tell your doctor if you are breastfeeding or plan to breastfeed.

The active ingredient in potassium chloride is excreted in human breast milk. The effect of potassium chloride on the nursing infant is not known.

If taking potassium chloride, salt substitutes containing potassium should be avoided.

Swallow capsules and tablets whole. Do not chew or crush contents of either the tablet or capsule.

• For patients who have difficulty swallowing tablets whole, the tablet may be broken in half.
• For patients who have difficulty swallowing capsules whole, its contents may be sprinkled into soft food followed by a glass of water or other liquid.

Hyperkalemia. Potassium chloride can lead to dangerously high levels of potassium, which could cause the heart to stop beating. Tell your doctor if you have a history of heart or kidney disease.
