Levoxyl (levothyroxine sodium) Tablets treat hypothyroidism (low thyroid hormone). It is also used to treat or prevent goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer. It is a replacement for a hormone that is normally produced by your thyroid gland. This medication is available in generic form. Common side effects include hair loss during the first few months of treatment. This effect is usually temporary as your body adjusts to this medication.

Dosage of Levoxyl is individualized. Levoxyl may interact with lithium, amiodarone, antidepressants, or radiation therapy with iodine. Many other drugs can interact with Levoxyl. Tell your doctor all prescription and over-the-counter medications you use. There are other drugs that can be taken while taking Levoxyl, but they must be taken 4 hours before, or 4 hours after taking Levolxyl. Consult your doctor. Current information shows Levoxyl may be used during pregnancy. Tell your doctor if you are pregnant because your dose may need to be adjusted. This medication passes into breast milk but is unlikely to harm a nursing infant. Consult your doctor before breast-feeding.
