Unknown. Speak with your wilson's specialist first. Then it might be best to have patch testing with an allergist to see if you react to the copper. Very likely it is safe, but there are other alternatives.....Why take the chance?
No, but try a Mirena (levonorgestrel) The CopperIUD is one of the BEST forms of birth control available. Non-hormonal (no effect on fertility/acne/headaches/nausea/wt gain/bloating/blood clots) and VERY safe (except if you have Wilson's dz/Copper allergy). Only risk is a heavier period and complications w/ insertion (RARE). Immediately effective to prevent pregnancy, but DOES NOT protect against STIs. OK for women who haven't had kids.
