Formoterol capsules should be refrigerated to maintain their potency and effectiveness. This medication, typically used in inhalers for asthma and chronic obstructive pulmonary disease (COPD), is sensitive to temperature and humidity. Storing the capsules in the refrigerator helps preserve their stability and ensures that they deliver the intended therapeutic effects when used.

While some medications may be adequately stored at room temperature or in a cool, dry place, formoterol requires colder conditions to prevent degradation. Freezing is also not suitable, as it could damage the capsules and compromise their functionality. Therefore, the correct and appropriate storage method for formoterol capsules is to keep them refrigerated.
