to add to my previous comment regarding anti biotics, this is what I would do.

1 - change some prescription drugs to no prescription needed. To relieve pressure on GPs.
2 - Add a system that these drugs when acquired from a chemist the nhs medical card and photo id needs to be presented.
3 - chemist clerk enters onto system drugs have been issued.
4 - repeat drugs cannot be issued for next 6 months without prescription.

so this prevents abuse.
