Final answer:
Some medications that can decrease the absorption of levothyroxine include antacids, calcium supplements, and iron supplements.
Step-by-step explanation:
Some medications that can decrease the absorption of levothyroxine include:
- Antacids: Antacids containing aluminum or magnesium can reduce the absorption of levothyroxine. Examples include Maalox, Mylanta, and Tums.
