Went for my asthma review today and met the clinical pharmacist employed by my surgery. I asked if I could be given two inhalers as one only lasted a a month.
As it happened she changed my inhaler to another type (I wonder if it's cheaper!) but she did say that all prescriptions would be changed in the near future to 1 month only in an effort to cut down waste. This will be a real pain for me remembering to request them in time and then going into town every month
I did argue that I took all my medication and didn't waste any. She then told me of a couple of cases where she had been to houses where she had found whole cupboards full of unused medication. It seems there are a lot of people who don't take their drugs but collect them anyway so that the doctor doesn't find out. I was horrified.
