Synthroid Side Effects

If you have low thyroid levels then you're probably familiar with Synthroid. Some Synthroid side effects may happen because your dose is too high so what you experience may be the effects of having high thyroid hormone levels. Synthroid is one of those medications where one dose doesn't fit all... your doctor will run lab tests and adjust your dose accordingly till it's just right.

Now some people have tried to use Synthroid to lose weight... this is NOT a good idea. Neither Synthroid, nor any other thyroid hormone hormone should be used to treat obesity or for weight loss. If your thyroid levels are normal, it will have no effect and if you take high doses of the medication, you put yourself at the risk of experiencing serious and even life-threatening toxic effects.
