Liquid Antibiotics Shelf Life: How Long They Last and When to Throw Them Out
When you pick up a bottle of liquid antibiotics, a suspension or solution form of antibiotics designed for easy dosing, especially for children or those who have trouble swallowing pills. Also known as oral antibiotic suspensions, they’re common for treating ear infections, strep throat, and pneumonia. But unlike pills, these liquids don’t last forever—once mixed, their potency drops fast, and using them past their safe window can mean your infection doesn’t clear up.
Most liquid antibiotics last 7 to 14 days after being mixed by the pharmacy, depending on the drug. Amoxicillin, for example, stays strong for about 14 days if refrigerated. Cephalexin? Only 10 to 14 days. Azithromycin suspension? Just 5 days after mixing. The fridge helps slow down breakdown, but even then, bacteria and mold can grow if left too long. Heat, light, and time all chip away at the active ingredients. If it smells funny, looks cloudy, or has chunks in it—pitch it. No point in risking a treatment failure or worse, a resistant infection.

Also known as beyond-use date, it’s not the same as the manufacturer’s printed expiration date. That date is for the unmixed powder. Once you add water, the clock starts ticking. Pharmacists write the new date on the label for a reason. Don’t ignore it. And don’t save leftover antibiotics for next time.

Also known as medication storage conditions, it’s not just about temperature. Some need to be shaken before each use. Others need to be kept away from direct sunlight. Always check the label or ask your pharmacist. A bottle left on the counter in summer heat could lose half its strength in days. And if you’re unsure? Call your pharmacy. They’ll tell you if it’s still good or if you need a new prescription.
