If you need more than a 30-day supply of hypothyroidism medication, you'll need to provide thyroid test results (called "thyroid labs" or "thyroid panels") from the past 12 months. Thyroid labs measure levels of thyroid-stimulating hormone (TSH), free thyroid hormones such as thyroxine (free T4), and triiodothyronine (T3).
If your clinician has concerns about your lab results, they may not renew your prescription.
