Never use amoxicillin after its expiration date. The date printed on the bottle indicates the medication’s guaranteed potency and safety. After this date, the drug’s effectiveness may decrease, potentially leading to treatment failure. Discard any unused amoxicillin after the expiration date according to your local guidelines for proper disposal of medication.
Factors Affecting Amoxicillin’s Shelf Life
Storage significantly impacts amoxicillin’s lifespan. Always keep it in a cool, dry place, away from direct sunlight and moisture. High temperatures and humidity accelerate degradation. Improper storage can render the medicine ineffective before the expiration date printed on the label. Check the label for specific storage instructions from the manufacturer.
Recognizing Spoiled Amoxicillin
While amoxicillin doesn’t visibly change when it expires, its chemical structure degrades. A change in color, odor, or texture could indicate spoilage, though it isn’t always evident. If you notice any changes, discard it. Rely on the expiration date as the primary indicator of safety and effectiveness.
