Y42.2: Antithyroid drugs
Antithyroid drugs, as classified under the ICD-10 code Y42.2, refer to medications used in the treatment of conditions such as hyperthyroidism, where the thyroid gland produces an excessive amount of thyroid hormones. This medical condition can manifest in various ways including sudden and unexplained weight loss, rapid or irregular heart rate, sweating, nervousness or irritability, and changes in menstrual patterns among others. Sometimes, these symptoms may not be immediately recognizable and might be attributed to other conditions. The use of antithyroid drugs helps to regulate and reduce the production of these hormones. However, their management requires careful monitoring, as the misuse or inappropriate use of these drugs may lead to side effects or complications such as underactive thyroid gland or interactions with other medications.
