Most GP surgeries in the UK now should have electronic records, and serious conditions that should be taken into consideration should be flagged. As always, the data has to be entered correctly for it to be of any use. It takes a button click to access it and the GP should have a list of who they are seeing anyway. Before prescribing a doctor should check verbally what medication you are already taking, and if you have any allergies. No doctor/nurse should feel threatened if you ask what the tablets are and how will they effect you. There is a data sheet in every box, yes its give you lots of side-effects that most people do not get, but its good to know. The NHS is changing the way it gives information all the time, https://patient.info/medicine , if your practice is online you can check some information on your records.
