I advis my patiets to avoid medications like Ibuprofen for a week or so prior to surgery but taking them a week after surgery should be no problem. Be sure to check with your surgeon to be sure he agrees and also to be sure that Ibuprofen does not interfere with any other meds he may have prescribed.
It is best to ask your surgeon if you can take ibuprofen after BBL. Some surgeons might not want you to take it for fear of bleeding.
