Tattoos on Anticoagulants

At times, patients on anticoagulants are considering getting a tattoo.  I am not aware of any medical publication assessing the amount of bleeding with tattooing on warfarin or other anticoagulants.

However, some degree of  bleeding is common even in the individual who is NOT on warfarin:  One publication reported that the majority (76 %) of 664 army soldiers who had a tattoo reported small to moderate bleeding during the tattooing procedure [ref 1].   In another study, approximately 5 % of nearly 6,00o individuals receiving a tattoo reported some bleeding [ref 2].   I would expect that the bleeding would be even more on anticoagulants.   Would the degree of bleeding cause any medical problems?  I don’t know.  Would the quality of the tattoo be less as some of the injected pigment may bleed out?  I don’t know. No report on tattooing in patients on anticoagulants appears to be in the medical literature.

In view of the lack of data,  I would, at present, advise against getting a tattoo while on warfarin or any of the other anticoagulants.   However, if a patient is very keen on getting a tattoo and is not at very high risk for thrombosis, it would be reasonable to discontinue warfarin 5 days prior to getting the tattoo and restarting it the evening of the day the tattooing has taken place, similar to the way warfarin is managed at times of non-major medical and surgical procedures.   In the case of the person on Pradaxa, discontinuation 2 – 2½ days  prior to getting the tattoo (and longer if the person’s  renal function is not normal) would be appropriate.
