Minami-Ikebukuro Parkside Clinic is a medical clinic located in Minami-Ikebukuro, Toshima Ward, Tokyo, specializing in endocrinology. The clinic provides specialized treatment for thyroid diseases, with particular attention to patients undergoing oral treatment for thyroid dysfunction or thyroid disorders. The official website cautions about the use of iodine-based gargle, advising patients visiting for thyroid diseases to generally avoid its use. According to the clinic's view, the effectiveness of iodine-containing gargle against COVID-19 has not been clarified at this time. Since continued use of iodine-based gargle may affect thyroid function, it is strongly recommended that patients with thyroid dysfunction or those undergoing oral treatment for thyroid diseases avoid its use. This view is based on the joint statement of the Japan Thyroid Association, the Japan Endocrine Society, and the Japan Association of Endocrine Surgeons. The clinic can provide services in English and is equipped with barrier-free facilities. The clinic is closed on Sundays and holidays, as well as on specific dates such as year-end and New Year holidays and Golden Week.
