Answer 1

WARNING: This medication should not be used either alone or in combination with diet pills to treat obesity or for weight loss because serious, even life-threatening, effects could occur. Large doses of this medication, especially with diet pills, may cause symptoms of toxicity. See the Side Effects and Overdose sections for more information.

Avoid the following food products, which can make your body absorb less Synthroid: infant soy formula, cotton seed meal, walnuts, and high-fiber foods.

All the websites I've looked at emphasize that you consult a doctor before using it with any other drug.
