For RAI to Work: The overall treatment is a little confusing as cancer is usually surgically removed, but there are a few reasons to lower your Synthroid (thyroxine). It may be held for a while so your left over thyroid tries to work and will suck up the RAI. The other reason is when the thyroid cells die they will release thyroid hormone. This could temp make you hyperthyroid. Eventually your dose will be adjusted again.
