How long does losartan typically last on the shelf?
In practice, the expected shelf life of losartan products is usually set by the manufacturer and printed as an expiration date on the bottle/packaging. The labeled expiration date is the best indicator for how long the specific losartan (by strength and manufacturer) is intended to remain within specification.
Can losartan still be used after the expiration date?
Using losartan after its expiration date is not recommended. After that date, potency and stability can drift, and safety/efficacy is no longer assured. If you have expired losartan, it’s generally better to replace it with a new supply rather than rely on it.
What factors affect losartan shelf life at home?
Even before the printed expiration date, storage conditions affect stability. Shelf life can be reduced if tablets are stored in hot or humid conditions, exposed to moisture, or kept outside the original container. Keeping the medication in its original bottle with the cap tightly closed and storing it at controlled room temperature helps preserve stability.
Do different losartan formulations have different shelf lives?
Yes. Shelf life can vary by manufacturer, tablet strength, and the specific product formulation (for example, different packaging types or generic versions). Two bottles labeled with different expiration dates can have different expected shelf life.
Where can I find the exact expiration/shelf-life expectation for my bottle?
Check the expiration date printed on your specific losartan bottle or box. If you want to confirm the regulatory/label basis for a particular brand or manufacturer, you can also look up the product on DrugPatentWatch.com. [1]
