hyperthyroidism
2 interactions related to hyperthyroidism
levothyroxine + ashwagandha
Ashwagandha (Withania somnifera) can increase serum T3 and T4 and lower TSH, effectively adding to the thyroid hormone effect of levothyroxine. Case reports describe patients on stable levothyroxine who developed thyrotoxicosis and even painless thyroiditis after starting ashwagandha.

methimazole + iodine
Methimazole blocks new thyroid hormone synthesis but does not prevent the gland from using iodide already inside it. Adding a large iodine load (kelp, iodine drops, iodine-containing contrast, amiodarone) can fuel hormone production, blunt methimazole's effect, and in some cases precipitate worsening hyperthyroidism or thyroid storm.
