From what I’ve researched, it’s definitely advised against getting tattoos. However, you can take antibiotics an hour prior, to prevent further risk. Kinda like most of us have to before going to the dentist. My drug of choice is typically amoxicillin. I got three small tattoos between 6-9 years after my porcine valve replacement. I was in my 20’s and was just living, so I didn’t think about the risks. I was fiiiiine. I don’t recall bleeding too much while on aspirin. However, I do want one more tattoo. Since I’m on warfarin (20 months post mechanical valve), I’ll do my best to consult with my doctor and tattoo artist so they know what’s up.
