Levothyroxine is not considered addictive, although signs and symptoms of levothyroxine withdrawal may occur if a person suddenly stops taking this medication. Some of these signs and symptoms can be serious or even life-threatening, so it is incredibly important never to stop taking this medication without the direct supervision and guidance of a prescribing medical provider.

Treatment Options
The best treatment option for levothyroxine withdrawal is to simply avoid it.
