I’ve seen expired Rogaine foam on ebay selling for rather cheap. I could understand that overtime, a drug might lose its effectiveness, but I can’t imagine that Minoxodil spoils like milk.
From a business standpoint, it would make a lot of sense for Pfizer to put an expiration date on their product in order to minimize competition with 2nd hand merchants. I acknowledge my ignorance in the subject, so I am appealing to you. Do you think using Minoxodil that’s a month or a year past its expiration date is any less potent?
Thanks for all of your hard work.
My official response is to follow the general advice on all expired medications and trash it.
Off the record, I think that expiration dates are often accelerated for the very reasons you are probing and would expect that if I was taking minoxidil that is properly stored 1 year past its expiration date, I would be comfortable using it. But don’t quote me on that, of course. Oh, this blog is public?!
