Np Thyroid is used to treat hypothyroidism (underactive thyroid gland), including Hashimoto's thyroiditis, thyroidectomy, and other conditions causing low thyroid hormone levels. It may also be used in certain cases of thyroid cancer and goiter.
As a natural desiccated thyroid medication, Np Thyroid contains both T3 (liothyronine) and T4 (levothyroxine) hormones extracted from porcine thyroid glands. These hormones supplement the body's natural thyroid hormone production to restore normal metabolic function.
Np Thyroid is typically taken once daily on an empty stomach, 30-60 minutes before breakfast. Dosage must be individualized and monitored through regular thyroid function tests. Patients should not switch between different thyroid medications without medical consultation, as potency may vary. Side effects may include symptoms of hyperthyroidism if doses are too high, including heart palpitations, weight loss, and anxiety. This medication may interact with certain drugs including blood thinners, diabetes medications, and antidepressants.
