I take the BoneSmart cocktail which works very well for me. That's 1000mg Tylenol and 800mg ibuprofen (two 500mg Tylenol tablets and four 200mg ibuprofen tablets). You can take this up to 4 times a day maximum---but only if you are not getting either of these OTC drugs in any other medication you are taking. If you are, you have to cut back by that much on the cocktail.
As you can see, Bottomshollow replied to a question with an answer that "this worked for me". I think that is why people come to forums, to see what worked for others. LJM then replied that she would check with her doc---and I agree with you that she made a good decision. However, she will now speak with her physician with some additional information, which is why she asked in the first place.
If you ask for advice from non medical folks-----all that they can provide is what worked for them. If you feel comfortable with that, fine----if not, then, yes, of course, check with your physician. All of us are ultimately in charge of our own health. I get advice and information from many sources, including Bonesmart. I have learned so much here about handling many aspects of my surgery and recovery from Tkrs. But---if I question anything, then I do as ljm will do and simply ask my physician. No one is telling ljm that she must do something---we are simply telling others what works for us! And frankly, that information has been invaluable to me and to many others on this forum and in probably why ljm asked us about this problem in the first place. Kelly
