Patients with hypothyroidism (low thyroid hormone levels) will require oral consumption of thyroid hormone (levothyroxine) daily. Dietary habits can influence how the body absorbs levothyroxine. Take levothyroxine once a day in the morning, ideally at least 30 -60 minutes before having breakfast or a drink containing caffeine, like tea or coffee. Food and caffeinated drinks can stop your body from absorbing levothyroxine properly, so it does not work either.
Certain medications and supplements decrease the absorption of thyroid hormone and should be taken 3-4 hours after taking thyroid hormone. These include
- Fiber supplements
- Calcium and iron supplements
- Proton pump inhibitors (omeprazole and pantoprazole)
- Multivitamins
- Soy products
Also, ensure that the medicine container is stored at room temperature, away from heat, moisture, and direct light. Keep from freezing.
