A Prospective and Observational Study on Thyroid Patients in Tiruvannamalai.

Abstract Background: Thyroid disorders are common endocrine conditions requiring long-term pharmacological management. Drug use pattern studies help evaluate prescribing practices and promote rational drug use. Objective: To assess the drug use pattern in patients with thyroid disorders and to analyze their demographic and laboratory characteristics. Methods: A prospective observational study was carried out among patients diagnosed with thyroid disorders in a tertiary care hospital. Data regarding demographics, laboratory investigations, and prescribed medications were collected using a structured proforma and analyzed descriptively. Results: Thyroid disorders were more prevalent among females and middle-aged individuals. Most patients showed laboratory features of hypothyroidism, including elevated TSH and reduced free thyroid hormone levels. Levothyroxine monotherapy was the most commonly prescribed treatment, while combination therapy was rarely used. Adjunct medications such as statins and nutritional supplements were prescribed based on associated comorbidities. Lifestyle and dietary advice was provided to all patients. Conclusion: Levothyroxine monotherapy remains the cornerstone of thyroid disorder management. The observed prescribing pattern reflects rational and guideline-based therapy, emphasizing the importance of comprehensive patient care.
