My daughter takes Synthroid (thyroxine) for hypothyroidism and has become very emotional and hyper. Is this normal behavior?

5 doctors agree
In brief: No
Kids who are treated for profound hypothyroidism can exhibit some symptoms of what seems like hyperactivity as their body gets used to being back on track.
However, if a child has been hypothyroid long enough, problems like learning disability or adhd may exist already, but unmasked with treatment for hypothyroidism. Please speak to your child's doctor about this.

One other comment: if she's on too much Synthroid, this can make her hyperthyroid and more emotionally labile. If she hasn't had her thyroid function tested in awhile, your doctor may want to take a look at thyroid tests again.

In brief: Could be hormone XS
Definitively need a check up to make sure the dose is right.

The hypothyroid patient may go thru periods when their daily dose does not match their needs.
Too much may cause increased emotional lability, declining school performance, tremors, difficulty sleeping, etc. I would get with your doctor & check a blood level to see if it is high. Meds can be adjusted if appropriate. If this is not the case other issues should be explored.
