That sounds a long time for a multi disciplinary team to meet and review this as most clinics do this within a day or a few days usually at most and I can only assume this is because they are just getting up to speed as a clinic but this does not help you in the slightest .
Also thinking about it since the 13th this will be the sixth working day since then so maybe it is not so far behind schedule as first appears and I'd hope this will be sorted in the next day or so you can receive your meds soon as and in theory going forward you would not face this delay again as this team meets to approve new patients and sometimes if alterations to amounts a patient is requiring changes .
