Table of contents:

Micro-K Extencaps is a prescription medication commonly used to treat or prevent low levels of potassium in the blood. It is oral dosage form of microencapsulated potassium chloride used as a potassium supplement. It works by providing the body with a source of potassium, an essential mineral that helps cells, kidneys, heart, muscles, and nerves to function properly.

Potassium is needed to maintain the body's fluid and electrolyte balance, and to support nerve and muscle function. In cases where the body has low levels of potassium (hypokalemia), Micro K Extencaps can help to restore normal levels of the mineral.

Use and Dosage

Micro K Extencaps comes in the form of Capsule to take by mouth as directed by your doctor. Take each dose with a meal and a full glass of water unless otherwise directed by your doctor. After taking the capsule, do not lie down for at least 10 minutes to prevent stomach upset.

Swallow the capsule whole and not crush or chew extended-release capsules or tablets as doing so can release all the drug at once and increase the risk of side effects. If you have difficulty swallowing the capsule, inform your doctor or pharmacist. Micro K Extencaps can be opened, and the contents sprinkled onto a spoonful of soft food such as applesauce or pudding. Do not prepare the mixture ahead of time and immediately swallow the food/medication mixture without chewing. After taking each dose, drink a glass of cool water to ensure you have swallowed all the medication.

Take Micro K Extencaps regularly to obtain the most benefit from it. To assist in remembering, take it at the same time(s) every day. The dosage is determined by your medical condition and response to treatment. Do not increase your dose or take it more often than prescribed. The maximum recommended dose is 20 mill equivalents per dose.
