You are taking levothyroxine, and your thyroid levels keep fluctuating.



You're not taking your levothyroxine consistently, regularly, or correctly 


You should take levothyroxine in the morning, ideally on an empty stomach, at least 30 to 60 minutes before eating breakfast or drinking coffee or milk – and at least 4 hours apart from supplements that contain calcium or iron -- which can all negatively affect absorption. Aim to take it at the same time, and consistently, every day. 

For levothyroxine tablets and capsules, it’s recommended that you take them with a glass of water.

Tablets can be safely split. You can’t split Tirosint® capsules.

Tirosint®-SOL oral solution is packaged in individual dosage ampules. You can take the liquid levothyroxine directly in your mouth, or dilute it in water.

Note: Tirosint® capsules and Tirosint®-SOL oral solution are more resistant to food, coffee, milk, and calcium and iron supplements, but experts still recommend following these guidelines for best absorption.
