Taking Thyroid Medication But Not Feeling Better? Avoid these common mistakes.
When Should I Take My Thyroid Medication?
Here are the Current Guidelines for taking Thyroid medication
Levothyroxine is absorbed in the small intestine and is 70%-80% bioavailable in the euthyroid individual. Peak absorption is achieved at approximately 2 hours after oral ingestion but can be delayed to 3-4 hours if it is ingested simultaneously with interfering medications, supplements, or some foods/drinks.
According to Current guidelines by the American Thyroid Association you should take levothyroxine at least 60 minutes before the first meal of the day or at bedtime (at least 3 hours after the evening meal), and at least 4 hours apart from other medications or supplements, if possible.
What substances can block absorption of the medicine?
Levothyroxine tablets are not well absorbed when taken with Coffee, Soy, Cow’s milk, Iron (think twice if you are taking your levothyroxine every morning.
Taking levothyroxine together with an interfering substance can decrease the amount of thyroid hormone that is absorbed by as much as 50%. This is really significant.
Other factors affecting thyroid medication absorption
Certain conditions have the potential to further reduce the absorption of oral levothyroxine. If an Helicobacter pylori infection, atrophic gastritis, or celiac disease for example can necessitate a higher dose because of poor absorption of the medicine in the gut.
