Hello – This option is often referred to as Block & Replace. The physician prescribes large doses of Anti-Thyroid Drugs to shut down thyroid production completely, and then adds in replacement hormone to normalize thyroid hormone levels. However, this option is not commonly used in the U.S.. There was a study in Japan done where B&R produced very high remission rates – but unfortunately, these results haven’t been replicated here in the U.S. Also, there is concern that the higher doses of meds may be correlated with a higher rate of side effects, such as liver and white blood cell issues.
Hope this helps – this is obviously a difficult decision that you and your doctor will want to make together.
