Synthroid (active ingredient: levothyroxine sodium) is a prescription medication indicated for the following:

Hypothyroidism: Synthroid is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. It helps to restore normal thyroid hormone levels in the body, improving symptoms such as fatigue, weight gain, and depression.
Thyroid Cancer: Synthroid is used as an adjunct to surgery and radioiodine therapy in the management of certain types of thyroid cancer.
Goiter: Synthroid is indicated for the treatment and prevention of goiter (enlarged thyroid gland) due to various causes, including thyroid nodules, Hashimoto’s thyroiditis, and other conditions.

Synthroid belongs to a class of drugs known as thyroid hormones, which works by replacing or supplementing the thyroid hormone that is normally produced by the thyroid gland, thereby helping to regulate the body’s energy and metabolism.

Take Synthroid tablet exactly as prescribed by your healthcare provider. Take the tablet by mouth as directed by your doctor, usually once daily on an empty stomach, 30 minutes to 1 hour before breakfast. Drink Synthroid tablet with a full glass of water unless your doctor directs you otherwise. Swallow the whole tablet and do not split, crush, or chew. People who cannot swallow the capsule whole (such as infants or small children) should use the tablet form of the medication.

The dosage of Synthroid may vary depending on factors such as age, weight, medical condition, and response to treatment. However, the usual initial dose for adults with hypothyroidism is 1.6 to 1.7 mcg/kg body weight per day, which may be adjusted based on thyroid hormone blood levels and individual response. The maximum daily dosage generally should not exceed 200 mcg per day for most adults.

Can Synthroid cause weight gain?

Weight gain is not a known side effect of Synthroid. However, if your dose of Synthroid is too low, it may not effectively manage your hypothyroidism symptoms, which could result in weight gain.
