Potassium is a mineral that helps your body regulate pH balance, build muscle and perform regular metabolic functions. According to the Linus Pauling Institute, recommended daily intake of potassium is 4,700 mg daily for most adults. Most people get enough potassium through their regular diet, but illnesses that include continuous vomiting or diarrhea could cause you to become deficient, a medical condition called hypokalemia. Potassium supplements are available to boost your levels and are usually administered orally.
Step 1
Be frank with your doctor about all medications you may be taking and be sure he knows about any pre-existing medical conditions that might affect your ability to take potassium supplements. According to the Mayo Clinic, potassium supplementation may not be appropriate if you are taking medication for congestive heart failure or high blood pressure. You may also need to use caution with potassium supplements if you have kidney disease, type II diabetes or Addison's disease.
Step 2
Discuss with your doctor which form of potassium you want to take, as the supplement is available as a powder, liquid, tablet or capsule. Your decision may be guided by the concentration of potassium that your doctor finds necessary to correct your deficiency. Taking too much potassium can lead to potentially serious symptoms such as a weak pulse and heart arrhythmia.
Step 3
Understand the type of potassium supplement you have been prescribed--the difference is in the salt formulation of the supplement--and the correct dosage. For example, potassium bicarbonate or potassium citrate is usually given up to twice daily, at 25 to 25 milliequivalent dosages each time. Potassium chloride doses generally range between 20 and 40 milliequivalents daily, according to the Mayo Clinic.
Step 4
Take your potassium supplement with at least 4 oz. of water or juice, but preferably a full 8 oz. glass. Liquid and powdered forms must be completely blended into the liquid to prevent an upset stomach. According to the Mayo Clinic, if you do not dissolve non-tablet forms of potassium before taking them, you could experience a laxative effect. If you are taking a pill form, swallow the pill whole with water or juice without crushing or chewing the supplement.
Step 5
Avoid an accidental overdose by skipping a forgotten dose of potassium, and resume your regular dosing schedule for the next dose. Let your doctor know if you experience side effects such as blood in your stool, muscle weakness or vomiting, so she can re-evaluate and adjust your dosage.
Tips and Warnings
- Severe hypokalemia can be characterized by abnormal heartbeat, muscle weakness or paralysis. If you are diagnosed with this serious condition, your doctor may use an injectable form of potassium to boost your blood levels.
