What are the side effects of thyroid replacement?
Since thyroid hormone as it is available now on the market is the exact replica of the thyroid found in the body. If it is replaced with the proper dosage, there should be no side effects. Problems arise when it is replaced either inadequately or in excess. When this is the case you will experience the dangerous side effects mentioned in the first part of this section. To avoid this, levels of thyroid hormone should be monitored very carefully, especially initially. Often the alteration of other hormones such as estrogen, the birth control pill, or other hormones can change the concentrations, thus again close monitoring is important.
