From the Guidelines
The treatment for subacute thyroiditis primarily focuses on symptom management, with beta-blockers such as atenolol or propranolol recommended for symptomatic relief, and close monitoring of thyroid function every 2-3 weeks after diagnosis to catch the transition to hypothyroidism. According to the guidelines outlined in the Journal of Clinical Oncology 1, the management of subacute thyroiditis is based on the severity of symptoms.
Treatment Approach
- For asymptomatic or mild symptoms (G1), patients can continue with their current treatment, and beta-blockers can be used for symptomatic relief, with close monitoring of thyroid function every 2-3 weeks.
- For moderate symptoms (G2), consideration should be given to holding treatment until symptoms return to baseline, with endocrine consultation and beta-blockers for symptomatic relief.
- For severe symptoms (G3-4), treatment should be held until symptoms resolve to baseline, with endocrine consultation, beta-blockers, hydration, and supportive care, and consideration of hospitalization in severe cases.
Monitoring and Follow-up
- Thyroid function tests should be monitored every 2-3 weeks initially, then every 1-2 months until recovery.
- Patients should be evaluated for transition to hypothyroidism, and treated accordingly with levothyroxine replacement if necessary.
Additional Considerations
- Rest and supportive care are also important components of treatment.
- For persistent thyrotoxicosis (> 6 weeks), consideration should be given to endocrine consultation for additional workup and possible medical thyroid suppression.

From the Research
Treatment Options for Subacute Thyroiditis
The treatment for subacute thyroiditis focuses on relieving pain and controlling the inflammatory process. The main treatment options include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or loxoprofen 3, 4
- Glucocorticoids such as prednisolone or methylprednisolone 3, 5, 6, 4
- Beta blockers to treat adrenergic symptoms in the hyperthyroid phase 7
- Thyroid hormone therapy in patients with signs and symptoms of hypothyroidism or permanent hypothyroidism 7
Comparison of Treatment Outcomes
Studies have compared the treatment outcomes of NSAIDs and glucocorticoids in subacute thyroiditis:
- A study found that glucocorticoid treatment was associated with a lower incidence of permanent hypothyroidism than NSAID treatment 5
- Another study found that prednisolone treatment was superior to NSAIDs in resolving symptoms, but the time period to normalization of thyroid function was comparable between the two groups 4
- A randomized controlled trial found that short-term prednisone treatment had a better safety profile and similar efficacy and recurrence rates compared to 6-week prednisone treatment 6
Factors Affecting Treatment Outcomes
Certain factors can affect treatment outcomes in subacute thyroiditis:
- Positive thyroid peroxidase antibody (anti-TPO) was determined as a main risk factor for permanent hypothyroidism 3
- Treatment with only ibuprofen was also determined as a main risk factor for permanent hypothyroidism 3
- The recurrence rate was observably higher in patients receiving glucocorticoids than in those receiving NSAIDs 5
