Except perhaps in February.
I'm on a repeat prescription and every single time I have to chase my GP to reissue it to my chemist (who apparently send them reminders a week before I'm due to run out).
I get 56 tablets a month and take 2 a day - simple maths they last 28 days so I need 13 prescriptions a year but the receptionist told me thsi morning that their computer will only issue it on the 16th of each month regardless of length of month or the fact that I only get 4 weeks worth at a time. Everytime she makes me talk to a GP in order to override the computer - this has been going on over a year now.
Last time I missed a couple of doses I was in hospital for a week - the prescription is CONSIDERABLY cheaper than the impact of not taking it....
