Should a person with hyper thyroidism take typical thyroid medication like synthroid (thyroxine)?

Usually not: Usually, a person with hyperthyroidism has too much thyroid hormone in her body. One would take Synthroid (thyroxine) (synthetic hormone) to make up for a lack of enough thyroid hormone due to HYPOthyroidism. A person with HYPOthyroidism who becomes hyperthyroid due to taking too high of a dose of Synthroid (thyroxine) might be asked to take Synthroid (thyroxine) (at a lower dose) even though she is temporarily hyperthyroid.
