Use a disposable needle only once, then throw away in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.

If you need medical tests, tell the doctor ahead of time that you are using sodium iodide.

Sodium iodide may be only part of a complete program of treatment that also includes a special diet.
