Is it OK to use Latisse if it has been expired for several years but remains unopened?

You should never use a medication that has expired (this includes topical medicines like Latisse) even if the bottle hasn't been opened.  There is an expiration date on bottles for a reason.  Medicines and other chemical ins them degrade over time and they can lose their potency or become other forms of chemicals that have other effects.  Be safe!

Thank you for your question.  I would not recommend using expired Latisse or other other medications for that matter.  It is safer to use a product within its designed shelf life.

Thank you for your question.No.If the product is expired do not use it. Throw it out and purchase a new latisse  product.

No. If the medication is expired, throw it out. At the very least, the efficacy will be affected. And since latisse is used around the eyes, other issues could occur. Hope this helps, Dr. Nazarian

I would not use anything expired, although no studies have been done to show if this works or not.  I doubt it will harm you in anyway.  Best, Dr. Emer.

Thank you for your question.  I would not recommend using expired medication whether it is topical, oral, and other form.  The expiration date is required by the FDA to ensure consistency and safety for the patient.  Regards, Dr. Matt Elias

It would not be wise to use any product, especially one to be used around the eyes, past the expiry date.

An expiry date for any topical medication is designed to guard against loss of effectiveness of the drug, and contamination with bacteria. With regards to the former, the product is likely to retain some potency, but no studies are available to quote exactly how much. On the latter front (infection), since its unopened, that concern may not be applicable if the bottle is otherwise intact.Since it is an external application, you may try it once, and continue if there is no specific concern. However, whether it will work for the purpose (lengthening lashes) or not remains unanswered. May be you would be the first one to discover that!
