How long are metformin pills good?

The shelf life of metformin pills can vary depending on the manufacturer and specific storage conditions. Typically, metformin pills should be stored in a cool, dry place, protected from light, and at a temperature not exceeding 25 °C (77 °F).

When stored under the recommended conditions, the typical shelf life of metformin pills is between 1 to 3 years from the date of manufacture. The expiration date should be indicated on the medicine bottle or packaging. It is generally recommended to use the medication before the expiration date to ensure its potency and effectiveness.

If you have metformin pills that have exceeded their expiration date, it is advisable to discard them safely and appropriately, and obtain a new prescription from your doctor to ensure the medication's safety and efficacy. Never use expired medications unless specifically instructed by a healthcare professional.
