Hello and welcome - I've never heard of a doctor pushing surgery or RAI simply because antibody levels didn't go down! Some docs will recommend RAI or surgery after 12-18 months on Tapazole, but we are seeing a lot more support in the medical community for longer term use.
Issues where doctors might be more likely to recommend RAI/surgery would be if your husband is having serious side effects with the Tapazole, or if the Tapazole isn't effectively controlling his thyroid levels.
Hopefully, others will chime in - but we have community members here who have shared past experiences with both RAI and surgery, so you can use the “Search Posts” feature to look up old posts by keyword.
If your husband wants to pursue surgery/RAI, great - but he needs to understand the risks and benefits, and also the fact that he won't get a “do-over” if he changes his mind later!
If he's currently being treated by a primary care provider, an appointment with an endocrinologist might be helpful. (Or consider a second opinion). You can find doctors near you using the “Looking for a Doctor?” thread in the announcements section of the forum.
