Most pharmacies, especially small town mom and pop shops, try to project the exact amount of schedule IIs (particularly the strongest ones) they will need and order accordingly. A generous inventory is costly and makes them more vulnerable for robbery if the general public knows they have them. Some pharmacies deny they carry certain meds to the general public and one doesn't know they have them unless your doc calls in and says you will be coming in with a script for the medication.

They do their best to order accurately but one never knows when they will aquire a new customer who comes in with a script two days before you generally call in a refill. It only takes a few days for them to get the med. back in for you and that is no problem IF you have a bit of a stash. That isn't always easy to do if the medication is time released as opposed to a breakthrough. None the less, it is wise to try to keep at least a one week stash of all of your pain meds. There are all sorts of possible problems which can delay getting your refills on the exact day. Best wishes.

I could only use the matrix patches. The others broke me out something awful, regardless of manufacturer.
