After my first TKR, I was referred to a pain management doctor, as I did not have good pain control, and I was heading in for the other knee to be replaced. She started me on Celebrex 3 days prior to surgery as it needs to build up in the system to work fully. This carried over to my THR, for the left hip.
I'm now preparing for my left THR, and have these things on the list to review with the surgeon as I really do not want to deal with that horrible level of pain I had first time around.
I have autoimmune disease, so I can take acetominaphen but not ibuprofen (Advil, Motrin). The surgeon has put together a cocktail of meds that he thinks will work best for you, based on your health, history, and other medications. Ask the surgeon to explain, or even phone a pharmacist (preferably one you use, lol!) to help understand it better. Great that you are asking these questions. Because sometimes we DO catch something that needs adjusting!
