Quick Answer
Potassium iodide expires approximately 3 years from the date of manufacture, and its effectiveness decreases over time. The tablets should be stored in a cool, dry place to maintain potency.
Shelf Life and Storage
Potassium iodide tablets have a shelf life of approximately 3 years from the date of manufacture. This timeframe is determined by the American Society for Testing and Materials (ASTM) and the United States Pharmacopeia (USP). To maintain the tablets’ potency, store them in a cool, dry place, such as a cupboard or drawer, away from direct sunlight and moisture.
Dosing Effectiveness Over Time
Studies have shown that potassium iodide tablets retain their effectiveness for at least 2 years after the expiration date. However, it is essential to note that the tablets’ potency may decrease with age, and their effectiveness may be reduced. To ensure the tablets remain effective, check the expiration date on the packaging and follow proper storage procedures.
Packaging and Labeling
When purchasing potassium iodide tablets, make sure the packaging is intact and the label is legible. Check the expiration date and the manufacturer’s instructions for use. If the packaging is damaged or the label is unclear, do not use the tablets. Potassium iodide is available in various packaging formats, including individual tablets, blister packs, and multi-dose vials. When storing the tablets, keep them in their original packaging to maintain their effectiveness.
