Final answer:
Certain factors can prevent the complete absorption of Synthroid, a medication used for hypothyroidism. These factors include certain foods, supplements, antacids, and medications.
Step-by-step explanation:
Iodine and iodide are absorbed most readily from the small intestine. Organic iodide compounds (diiodothyronine and thyroxine) are partly absorbed as such and a part is broken down in the stomach and intestines with the formation of iodides. Absorption also takes place from outer mucus membrane and skin.
In the case of Synthroid, a specific medication used for hypothyroidism, certain factors can prevent its complete absorption. These include:
- Foods and supplements rich in calcium or iron, as they can interfere with the absorption of Synthroid. It is recommended to take Synthroid at least 4 hours apart from such foods or supplements.
- Antacids that contain aluminum or magnesium, which can decrease the absorption of Synthroid.
- Some medications such as proton pump inhibitors (PPIs) and certain antidepressants, which can interfere with the absorption of Synthroid.
