Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: 79M approx.. 6 195 lbs. asthma (we have no idea what meds he is on or prescribed at ER)My FIL (79M) was taken via ambulance to a small local community hospital on Tuesday and diagnosed in the ER with having had a TIA due to Afib. Heart issues is something that was unknown to them previously so he was not previously on any meds for that. My husband got up there in time to interact with the doctor at discharge and specifically heard the doctor tell FIL and MIL that he needed to take the meds he was being prescribed and see cardiology and neurology as soon as possible. This was a small local community hospital outside of San Diego but they are in an area with a large senior population where they probably see this a lot. My husband felt the instructions were clear and relayed succinctly.Because my own father has a long and fantastic experience with both cardiology and neurology at the large very well respected university medical center my husband asked me if I could make appointments for his father there as we figured inlaws were overwhelmed among other issues. I was surprisingly able to secure him appointments for this Monday and Tuesday respectively (6 days post ER visit). Husband told MIL that evening that appointments were secured for FIL at the university hospital.Now today my husband learns that MIL took FIL to their GP yesterday (day after he was released and before specialist visits) to their GP (whom my husband refers to as Dr. Quack due to his negligent care of his aunt resulting in her subsequent death due to melanoma so we may be biased here and this is why we are asking) told him he didnt need coumadin that he was just stressed and he just needed some Xanax to relax. So FIL told my husband today that he stopped the meds that ER doc overprescribed and am just taking the Xanax. I FEEL GREAT! FTR we have no idea what the other meds were and now they wont tell us.MIL is exploding at my husband and accusing him of a lot of wildly ridiculous things and FIL is trying to keep the peace and just shutting down. As a bit of background there are A LOT of issues with MIL and her behavior and this is pretty standard. Husbands basic rule is that we just need to prevent her from harming others and just tune her out otherwise. So our question is will this change of meds harm FIL and husband needs to intervene more strongly or is this something standard? TIATLDR: is it medically acceptable for a GP to remove someone from blood thinner (Coumadin?) less than 48 hours after a TIA and replace with Xanax even before they have seen cardiology or neurology?Edited to clarify timing. ### Response: Everything here is just odd. No way of knowing what's what without the hospital records. Please be sure to take them with you to the neurologist and cardiologist..
