I think pharmacy is obviously alot more vocational, where you have a lot of job opportunities in hospital, community and even industrial pharmacy. I had offers to do pharmacy but on deciding that i liked the science behind pharmacy, but not the career as such, i chose pharmacology. Alot if people (mainly pharmacist students) will tell you its a bad decision. In my opinion it only is if you want to become a Pharmacist. But a life science degree like pharmacology does have job prospects. There area lot of research careers but if working in a lab isnt your thing then there are jobs which are slightly related, such as medical writers, reulatory affairs and Clinical research associates- which work in clinical trials along with doctors. If your a multitalented person and show hard work you can progress with these to earn big money if you like. But to be honest im not all that driven by money, and after about 5 years experience as a CRA you can earn up to £35000+ as a senior CRA, then have the opportunity to move into other career paths such as project management. On considering it a CRA job sounds really good to me- you can earn a decent living, tehre are plenty of jobs in scotland and s.england, you get to work with lots of different people and you can use your knowledge of science.
Even if you dont want to use your degree a science degree such as pharmacology does show to employers taht you can grasp difficult subjects and there are a lot of graduate training schemes in many buinesses.
So if you know you really want to do pharmacy then definatly go for that, but if your unsure what you want to do and are thinking of pharmacology dont despair, there are jobs out there, very few specifically asking for a pharmacologist, but at least you wont have as narrow a career path as pharmacy.
