The three standard treatments for
Graves Disease are anti thyroid drugs (which you are taking now), RAI
treatment and total thyroidectomy.
Usually, drugs are used to treat intially and to stabilize thyroid levels before either of the other 2 treatments are considered. In some cases, anti thyroid drugs are used for 12-18 months to treat. In some cases, remission is achieved using drugs and no further treatment is needed. However, this only happens in relatively few cases.
