Finasteride past the 'used-by' date

Recommended Posts



I bought some finasteride on holiday (legitimately as I had a prescription), as it is 10 times cheaper then in my native country. I bought two years worth, but after the first twelve months, the stock becomes older than it's printed 'use-by' date.


Does anyone have any opinions as to whether or not it will still be effective after the 'use-by' date?

The potency of many drugs remains stable for many years/decade post expiration date.


Storage conditions play a role in its stability but that goes for drugs not "expired" as well so...


"Used by" variable re: potency of a drug is just a guide.


I think you made a good deal.
