Thyroget-75 Tablet 120's is used to treat hypothyroidism (underactive thyroid). It contains Thyroxine sodium, which replaces or provides more thyroid hormone in the body when the body is unable to naturally produce enough thyroid hormone (Thyroxine) to meet the requirements of the body. Thus, it helps to restore thyroid hormone for proper digestion, muscle functioning, brain development, and maintenance of bones. It may cause side effects such as headache, diarrhoea, nausea, vomiting, sweating, muscle cramps, shaking (usually of hands) and feeling restless or excitable, or problems sleeping. Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
