I sometimes have problems with the chemist obtaining vagifem. It is something to do with a 'quota'. I don't pretend to understand it at all, but small chemists get an allocated amount which gets used, then they have to order it (or something like that

)
It means my prescription can end up delayed by several days, especially if there is a weekend, and if the assistants haven't understood the ordering system properly (which isn't the usual way).
I can't for the life of me make any sense of it

, but for this reason, I usually order it at least 2 weeks or more ahead.
