As the forum users have said above, there isn't a great need for you to retake IELTS.
I personally obtained 7.5 on average with 7.0 or above in each section. This is good enough for all the medical schools in the UK as far as i'm concerned. However, the offer letter sent to me by Nottingham University didn't even mention a single word about/related to IELTS. This however, might not imply they wouldn't ask for it by the time i accept their offer. But, the only thing that i'm sure is it's NOT written on the offer letter.
Besides, i think it'd be better for you to be aware of the individual Pharmacy schools' IELTS requirement. I was once addicted to the prospectuses, especially the universities that i've applied to, and therefore came across the pharmacy courses, without realising it. So far, i haven't seen a university that asks for an overall band score of 7.0 or higher for Pharmacy. You might like to check the minimum band score requirement for individual section though. For Medicine, it's clearly stated that one needs to obtain at least 7.0 or above in each section.
The best and most reliable information that you could get is to call the admissions office up. If you think that's a little bit too expensive, send them an email. It normally doesn't take more than 5 working days for them to get back you. All the best and please do post something in my thread in the '' All about UK'' section under ''Education''.

You might want to request for a re-mark of your speaking section, it seems to be abnormally low compared to the other sections. I'm afraid there might be some error in the printing process or something. Besides, if you think you're confident with your spoken English and don't deserve that band score, i would strongly suggest you to go for a re-mark.
