Question

What are the negative food reactions for synthroid?

Answer 1

The only thing I've found is that some foods cause synthroid to not absorb as well as it could. These include: infant soy formula, cotton seed meal, walnuts, and high-fiber foods.

If you use any of the following drugs, use them at least 4 hours before or 4 hours after you take Synthroid:

calcium carbonate (Caltrate, Citracal, Oystercal, and others);

ferrous sulfate iron supplement;

sucralfate (Carafate);

sodium polystyrene sulfonate (Kayexalate, Kionex, and others);

antacids that contain aluminum (Amphojel, Gaviscon, Maalox, Mylanta, Riopan, Rulox, Tums, and others); and

cholesterol-lowering drugs cholestyramine (Questran) and colestipol (Colestid).

Also, iodine can increase natural production of thyroid hormone. Fluoride binds with iodine and prevents absorption of thyroid hormone.
