How Respiratory Medications affects thyroid medication
Levothyroxine absorption is sensitive to timing relative to food, calcium, iron and several medications. Whether Respiratory Medications interferes depends on Albuterol, Budesonide, Formoterol, Montelukast — most agents in Respiratory Medications have no clinically meaningful effect on thyroid hormone levels, but a small number affect TSH or T4 free fraction. Asthma is treated with short-acting beta-2 agonists for relief, combined with controller medications such as inhaled corticosteroids, long-acting beta-2 agonists, long-acting muscarinic antagonists or leukotriene recepto…
Practical timing
According to standard endocrine practice, levothyroxine is taken on an empty stomach at least 30 minutes before food and 4 hours from interacting medications.

When should I take Respiratory Medications relative to levothyroxine? ▾
Levothyroxine is taken on an empty stomach with at least a 30-minute fast and 4-hour separation from interacting medications.
