The Klarity Health platform offers a convenient and accessible way to connect with qualified providers who can help you manage your hyperthyroidism and determine if methimazole is right for you.

Methimazole is a commonly prescribed antithyroid medication, but it’s not the only option available for managing hyperthyroidism and related thyroid conditions. Depending on the patient’s medical history, treatment goals, and how quickly symptom control is needed, several alternatives may be considered. Each alternative has different mechanisms of action, durations, and administration routes.
Here’s a comparison of some of the most commonly used options:
| Medication | Class | Common Uses | Oral Availability |
| Propylthiouracil (PTU) | Thionamide (Antithyroid) | Graves’ disease (esp. in pregnancy or thyroid storm) | Yes |
| Lugol’s Solution (10% potassium iodide and 5% iodine) | Iodine preparation | Pre-thyroidectomy, thyroid storm, short-term use to suppress thyroid function | Yes |
| Saturated Solution of Potassium Iodide (SSKI) | Iodine supplement | Hyperthyroidism, thyroid block following radiation emergency, expectorant | Yes |
| Sodium iodide I-131 | Radiopharmaceutical | Hyperthyroidism, diagnostic agent for thyroid function, thyroid cancer | Yes |
Some options, like propylthiouracil (PTU) or Lugol’s solution, may be better suited for certain populations, such as pregnant individuals or those experiencing thyroid storms. Others, like radioactive iodine, offer a more definitive treatment option for those who do not respond or who cannot tolerate long-term antithyroid medication.
Preparations like Lugol’s Solution and SSKI are typically used short-term, often before surgery or in emergencies. The route of administration, duration of action, and patient-specific factors such as pregnancy, liver function, and urgency of treatment can all play a role in selecting the most appropriate alternative.
A telehealth provider can help assess which antithyroid strategy is best suited for your needs, whether you’re starting a new treatment, switching medications, or considering longer-term options like radioiodine therapy.
