Hmmm... not sure I have an answer for you, Vortex, but I would think, providing you ordered from the same pharmacy, they wouldn't allow you to order if it were too soon. But then, depending on how long your Rx was for- i.e. 25 days, 28 days, etc. might be the deciding factor?

Hope this helps and I wouldn't give it too much worry- if it was an accidental error, they should be pretty forgiving. I'm sure somebody else could be of more help to you than I can. I only use one OP and they run a tight ship
