Patients entitled to Medical exemption certificates are given these for an array of long-term illnesses!. Ie: Diabetes, Stoma supplies.. etc.

But a lot of money could be recouped by the NHS if those medical exemption certificates are only used for the sole purpose of those illness medical requirements. Yet cough mixture, creams, HRT.. infact anything else nonrelated to the illness are allowed to be free as well, due to the initial exemption. If anything not related was charged for, a lot of money would be saved by the NHS.
