Yes, ditto everyone. What Marcia said about an occasional dose makes sense, but, as she suggested, check with your doctor to be sure.
Here's my Ibuprofen story: because I've had such back pain for years but didn't want to take meds that would interfere with driving, my job, and caring for my kids, I popped Ibuprofens 3 at a time 3 times a day or 2 Naproxens at a time 3 times a day. Did that for years! It helped a little, but at age 46 I was diagnosed with osteoporosis. When I found out that NSAIDS interfere with bone growth, I started wondering if I brought on this osteoporosis myself by all the Ibu's and Naproxens I took for so long. Maybe it's not related, but it's a question I've got for my ob/gyn next time I go in. I'm also wondering if the medication I take for the osteoporosis, Fosamax, has helped in getting some bone growth in my fusion. At only 6 weeks post op, my x-rays were showing bone growth around one of the cages. If the Fosamax is part of the reason I'm showing bone growth so early, maybe all fusion patients should be taking it! That's one I'm going to pursue with my surgeon. Especially for those with failed fusions, it seems like it would at least be worth a try.
So to make a long story short, I agree that it's best to stay away from Ibuprofen until your fusion is solid. Not worth taking the chance.
