It is meant to replace a hormone that is usually made by your thyroid gland. Generally, thyroid replacement treatment is to be taken for life. Thyroid hormones, including SYNTHROID, should not be used either alone or in combination with other drugs for the treatment of obesity or weight loss.

Larger doses may result in serious or even life-threatening events, especially when used in combination with certain other drugs used to reduce appetite.

Low levels of thyroid hormones (hypothyroidism) can cause weight gain, while unexpected weight loss can signal that too many thyroid hormones are being produced (hyperthyroidism). Hypothyroidism is much more common than hyperthyroidism.lood tests can diagnose many thyroid conditions. Thyroid-stimulating hormone (TSH) is a hormone that controls activity of the thyroid gland. If your TSH is high, this typically signals that your thyroid function is low (hypothyroidism).
