Thank you for your question. There is not a specific contraindication to using Sculptra in patients who are on warfarin. For a patient who is on warfarin your risk of bruising is going to be high. Because of the bruising you may be sore and you may not be able to do the post-treatment massage which I think is important. Why are you on the warfarin? In some cases the warfarin can be stopped for several days prior to the treatment but only the physician prescribing the medication can advise you about this. Check with your local plastic surgeon about their views on this as they would be performing the treatment. Tracy M. Pfeifer, MD, MS
