As my husband's blood pressure remains a little high, our doctor decided to up the dose of his Bilocor to 7.5 mg. He duly scribbled the prescription and I went off to get it filled. At the first two pharmacists I went to (with whom our Medical has a special deal), each young man frowned at the paper, then checked his computer, then told me they have never had stock of such a dose. One even showed me his screen - no orders in the last 12 months. Puzzled, I went back to our usual pharmacy and tried again. No problem: the lady showed me that on the prescription the doctor had crossed out '30' pills and substituted '45', meaning that the usual dose of 5 mg should simply be supplied with half as many again so that the patient then takes 1 1/2 pills at a time instead of one.
This did not seem to me to be rocket science. Next time I shall read the script myself - in case I have to explain something to those whose minds seem to run on one track.
