Icewater..... pharmacy and chemistry are quite different subjects, and will lead to very different careers. I would imagine chemistry is quite lab-based along with lots of theory that could lead to a career where you are lab-based, whereas pharmacy has a much more vocational and healthcare focus. For example, all pharmacy students who graduate after 2026/27 will be trained as IPs (independent prescriber) once they join the register.
Around two-thirds, (60-65%) of pharmacy degree graduates end up working in that old 'chemist shop'! where you will mix your science with pharmaceuticals, along with retail and the general public! If you are not a 'people-person' then I would avoid pharmacy. Also it can be fast-paced, and pretty stressful, so I always advise any prospective pharmacy students with anxiety issues to do a lot of thinking and research before signing up for a pharmacy degree. I know all jobs can be stressful, But working with the general public, especially ones that are unwell can be very challenging and not something that all people want to do, or are capable of doing!
One of the ladies in one pharmacy I locum at, her son did a chemistry degree, then a PhD, then a PGCE, and is now a science teacher so that's one option, if you would enjoy 'shaping young minds' or whatever the current buzz phrase is! Again, must like kids and be very resilient and have a lot of stamina she tells me, about her son. And I'm sure most people know that there is a lot of prep and marking outside of the 9 til 3 day, and 13 weeks holiday, alongside the social part of dealing with parents, school trips, etc
I would pick a few universities you like and have a read of their sites where there is usually a section on all the exciting things you can do with a degree in chemistry.
As for pharmacy, it has changed an awful lot since I qualified 30 yrs ago. Both the teaching of the degree and also the work that you will be doing at the end of it all.
It will take you 5 yrs to qualify as a pharmacist, usually 4 yrs of full-time study, then a foundation year, that used to be called the 'pre-reg year', then you do an exam set by the GPhC, and if you get enough ticks on that then you will join their register and be allowed to call yourself a fully-qualified pharmacist!
The career path can be interesting and varied, and differs from the old days, whereby you usually chose the community or hospital path.
These days the split is roughly 60/65% community or retail pharmacy, 25% hospital, and then 10-15% of 'all the other stuff!'
This is where you want to be for the most interesting and rewarding jobs/career paths.
A rapidly growing area is working in a GP surgery or for the PCN ( look all these acronyms up please, save my poor old fingers having to explain!).
This is one of the most sought after career paths right now and you will be using your degree knowledge more by doing medicine reviews, possibly running clinics like asthma or diabetes and prescribing for those conditions, along with seeing patients in a clinical setting rather than the consulting room of the local pharmacy.
This 10/15% section of careers also includes things like research, teaching, and of course the pharmaceutical industry. Some universities will push this option as part of their recruitment narrative, but can go rather quiet when you start asking for figures. I read a comment on here a few months ago that said, of their cohort of 150, only 1 person secured a job in the pharmaceutical industry. If that is your aim then I would read the sites of lots of drug companies and pay attention to the section on degrees that they look to when recruiting. I actually did this last year, and you may see pharmacy listed, but alongside many, many other degrees like pharmacology, biochemistry, genetics, etc, etc.
A good starting point might be deciding what kind of person you are, (Myers-Briggs 16 personality types, assessments, available free online, can be v interesting/useful if you have never done this before!!) do you like people and healthcare, and the old 'want to help people' line..... or do you like wearing a white coat and rattling test-tubes in a laboratory all day with similar intelligent peers? I think this is a very important point, apart from my humour. And I have met many pharmacists and GPs over the years who felt drawn/pushed into a particular career because of family, siblings, money, status, etc. Although with the advent of the internet it is much easier now to research things in much more detail than it was back in the day. The point I am trying to make is, besides choosing a degree, you are also choosing the kind of life you will end up having, and I know it was something I never really gave much thought to when applying for pharmacy.
When I was 17 it never really crossed my mind to look forward 5 yrs to what I would actually be doing when I qualified. Hopefully these days, schools and colleges focus on this much more.
I will give you one rather silly example. Pharmacies tend to open on weekends, and as an employee you will probably have to work alternate Saturdays/Sundays too if somewhere like Tesco/supermarket pharmacy. This came as a bit of a shock to a couple of lads in my peer group who were sports mad/ went the footie every Saturday! It may seem a really trivial thing, but not looking at where and when they would be expected to work came as a bit of a shock to these lads. I know one of them actually resigned one job when he was unable to come to an agreement on weekend working.
But anyway, sorry for rambling on, TLDR : think about things beyond the degree, and the type of job you may end up with 5 yrs down the road.
Especially with pharmacy, some new graduates find it hard that, after five years, they are going to be working in a retail environment. Basically a shop! And not all of the public actually know that you need a degree to be a pharmacist! It has gotten a lot better over the years, but there is still the 'you only put labels on boxes' mentality out there in some people!
And depending who you work for, you may find that the 'shop' or retail part of the business receives much more emphasis than the professional side that you as a pharmacist are more concerned with. This area can be a particularly contentious one between pharmacists and non-pharmacist store managers.
But hey, I could ramble on for hours, so I will wish you well, and just paraphrase former PM, Tony Blair:
Research, research, research!
I only wish, as I'm sure most over-50s do, that the internet had been around back when we were in the 6th form to help with course and career decisions !
