Metrodinazole...

[Eltortu]

...does it have shelf life?

 

[kinyonga]

It depends on the form how long its good for from what I've read.

 

[VonSockthroat]

Shelf life is determined by its manufactured date. Drug companies will tell you that Flagyl (metronidazole) is good for 2 years from the day it was manufactured. After that, it begins to lose potency.
