Does Anyone Know How Long It Takes to Suppress Tsh Levels

Does anyone know or have a guess of how long it would take, if treated aggressively by your doc, to suppress your tsh levels in the treatment of thyroid cancer.

I have been dealing with this issue for 7 months now and my levels are still not where they should be to properly suppress any reoccurrence of the cancer.

Thanks for your help

Welcome to e health forum.

Patients treated for differentiated thyroid cancer take a daily thyroid hormone replacement pill called levothyroxine (also known as T4). They take it both to avoid hypothyroidism (underactive thyroid condition) and to prevent growth or recurrence of their thyroid cancer.

Usually they receive a T4 dose large enough to suppress their blood level of thyroid stimulating hormone (TSH) below the normal TSH range. This is called TSH suppression. The ATA and ETA guidelines suggest TSH suppression when a patient has active tumor or has a very aggressive tumor that has been treated with surgery and radioactive iodine (I 131).

However, about 85% of patients can be shown to be free of disease after initial tumor treatment by testing the patient' serum thyroglobulin levels and performing neck ultrasonography. When the patient is felt to be free of tumor on this basis, the ATA and ETA guidelines suggest maintaining the blood TSH in the low normal level, which is particularly important in children.

Patients whose thyroid glands have been removed will need to be on levothyroxine medication for the rest of their lives. The medication, which is necessary for maintaining a person's full health, must be taken on an empty stomach. Generally, it should not be taken with other drugs, since a large number of drugs interfere with thyroid hormone getting into the blood stream.
