Can Thyroid Medication Cause Joint Pain?

Yes, thyroid medications can occasionally cause joint pain as a side effect. Both levothyroxine and liothyronine may trigger muscle and joint discomfort in approximately 2-5% of patients. This occurs most commonly when starting treatment or adjusting doses, as your body adapts to changing hormone levels. The pain typically affects large joints like knees, hips, and shoulders, and may be accompanied by muscle weakness or stiffness. Most joint pain from thyroid medication is temporary and resolves within 4-6 weeks as your body adjusts. However, persistent or severe joint pain should be evaluated by your healthcare provider, as it could indicate an allergic reaction or the need for dosage adjustment.
