Special information if you are pregnant or breastfeeding

If you need to take Synthroid because of a thyroid hormone deficiency, you can continue to take Synthroid during pregnancy. In fact, your doctor will test you regularly and may increase your dose. Once your baby is born, you may breastfeed while continuing to take carefully regulated doses of Synthroid.

Recommended dosage for Synthroid

Your doctor will tailor the dosage to meet your individual requirements, taking into consideration the status of your thyroid gland and other medical conditions you may have. Older adults often require somewhat smaller doses. To make sure the dosage is right for you, the doctor will monitor your thyroid hormone level with periodic blood tests.

Overdosage

An overdose of Synthroid can produce the same symptoms of overstimulation listed under "Synthroid side effects" Confusion and disorientation are also possible, and there have been reports of stroke, shock, coma, and death. If you suspect a massive overdose, seek emergency medical attention immediately.
