Potassium iodide liquid

Generic Name: potassium iodide (poe-TASS-ee-uhm EYE-oh-dide)
Brand Name: Yodefan

Potassium iodide liquid is used for:

Treating lung conditions or disease in which mucus complicates the condition (eg, emphysema, bronchial asthma, bronchitis). It may also be used for other conditions as determined by your doctor.

Potassium iodide liquid is an expectorant. It works by thinning mucous secretions (phlegm) in the lungs and making it less sticky. The mucus is easier to cough up. This reduces chest congestion, which helps make your coughs more productive.

Do NOT use potassium iodide liquid if:

  • you are allergic to any ingredient in potassium iodide liquid
  • you have iodine poisoning, Addison disease, kidney disease, lung disease, a skin disorder, stomach disorders, tuberculosis, or a history of preexisting thyroid disease
  • you are taking potassium sparing diuretics (eg, spironolactone) or potassium supplements

Contact your doctor or health care provider right away if any of these apply to you.
