Having completed my NVQ4 as a pharmacy technician, I would be sacked if I didn't ask a customer what meds they were on before handing out OTC meds,EVEN paracetamol,that needs to be reported.
Ibuprofen can be way more dangerous than paracetamol to many people,asthmatics,people with liver or kidney issues,people with IBDs,the list goes on,I'd report a pharmacy if they didn't ask the relevant questions,they could be responsible for someone falling seriously ill
