This probably won't apply in the OP's case (as he is going to London), but it's not always the case that medicines have to be collected from a pharmacy. If patients live more than "n" miles from a pharmacy (and I can't remember what "n" is) they collect prescriptions from their doctor, and doctors in rural and semi-rural areas maintain on-site pharmacies for that purpose. (Mine does - but I'm not allowed to use it, except in emergencies, because I live too close to the pharmacy)
