If he post dates one it will work.
Please note that post-dating script
s is illegal under U.S. law. I have even seen people get red-flagged by their PM just for asking about
that. Here's the statement from the DEA:
"The DEA regulations require that all prescript
ions for controlled substances "be dated as of, and signed on, the day when issued.'' 21 CFR 1306.05(a)."
For more information, here's the link where this came from: http://www.deadiversion.usdoj.gov/fed_regs/rules/2007/fr1119.htm
You can check your state law to see how long script
s are valid for. My doc will write me for a one-week prescript
ion & a 3-week prescript
ion. They are both dated the day of my visit & in IL C2 script
s are valid for 7 days, so it works out okay for me. Otherwise, you might try seeing if your doc will either mail you a 2nd script
or let you come in and pick one up.
