Is it ok to begin to take 600 mg of ibuprofen one week after fat injections? Why or why not?

There shouldnt be any issue starting non steroidal anti inflammatories at this stage.At one week post of there shoudnt be any significant  increased sleeding risk

If you take ibuprofen it can increase the chances of bleeding near any fresh wound.  Bleeding can actually decrease the blood supply to the newly grafted fat cells and can cause them to die more easily.  To play it safe, wait at least a week after surgery and avoid any bending/straining or heavy lifting as well.

We ask patients not to take ibuprofen, aspirin and other blood thinners before any procedure since these can cause bleeding and excessive bruising.  One week after your procedure you can restart these medications.
