Expiration of prescriptions?

[heysmilepretty.livejournal.com]

Hey VPers! I was written a prescription for Gynazole-1 by my gyno last August. Fortunately, I haven't needed to fill it... until now. However, I was wondering if anyone knows how long do I have before the prescription itself expires? Like, how long after when it was written can I get it filled? I'm in New Jersey if that makes a difference...

Thanks y'all :)
