[|Human|] Taking Bystolic 2.5mg. OD; Having two knees replaced next month ; been taking Instaflex for almost 2 years. it has helped  a lot, but I am Bone on Bone in both knees now. Hard to walk.I have to stop Instaflex, + Anacin, 3 xs a day ( 2 weeks before surrgery) . Is there a reaction to stopping it completely? Dr. said no Blood thiners !Dr. perscribed Tylenol with Codeine to use, if Reg. Tylenol doesnt work.
[|AI|]  HIF your knee surgeon has suggested stopping meds 2 weeks before, trust it won't harm.but there should be physiotherapy of both knees for good result post operative. Instaflex is a nutritional supplement claimed to prevent cartilage deterioration.its stopping won't revert changes in 2 weeks. Blood thinners are taken to prevent clots.if you are already on it for some heart issues or other clotting issues, you may recons ult your treating doctor...they are usually stopped before any surgery 2 weeks before to prevent excess bleeding during operation
