The most-common side effect of using Nature-Throid is temporary hair loss during the first few months of treatment as the body adjusts to the medication, states WebMD. Other serious-but-improbable side effects that require a doctor's attention include increased sweating, tiredness, diarrhea, shortness of breath and mood changes.
Nature-Throid is a medication made from the thyroid hormone of an animal and aims to replace the missing hormone that an underactive thyroid in a patient's body is not producing adequately, explains WebMD. People need the thyroid hormone in sufficient amounts in their bodies to maintain normal mental and physical activities. Doctors use Nature-Throid to treat hypothyroidism, other thyroid disorders such as goiters and to test for thyroid function.
Since the thyroid hormone is a naturally occurring substance in the body, the medication is safe for use by everyone including children, adds Everyday Health. However, the medication interacts negatively with drugs such as oral diabetic medication, birth control pills, salicylates, steroids and medications that contain iodine. For instance, antacids make it difficult for the body to absorb the hormone. Thus, those taking the thyroids hormone need to figure out, with the help of their doctor, which treatments to stop to avoid such interactions.
