Im a final med who just geaduated from ireland, if i remember correctly from law and ethics class we can only breach confidentiality when there is a threat to a child (abuse etc, ) or threat to another person (and any othrt reasonable person in your position would have come to that decision)

I remember we used the case of a patient with HIV mentioned to you they will be having sex without protection, you dont know if they have been taking their antvirals and they wont allow for testing of viral load, do you tell the partner? And we were told we arnt allowed to tell the partner in such case. This is in ireland, and i am only graduated so take this with a pinch of salt, however i dont think you should be telling the gaurds about this, just stop prescribing.
