De[ends: It variable depending on the med given and the manufacturer. You will have to ask your pharmacist this question as they know the manufacturer.

Levithyroxine : Yes it's true you should take this medication only with water and that's it. I recommend just 15 minutes but the key thing is not with food. The absorbption will go done and this the effectiveness of the drug.

Levothyroxine dose: It is recommended to take levothyroxine dose in the morning .Some physicians recommend taking dose two hours before eating, but at least 30 min. before eating.

Yes sensitive med: Administer in the morning on an empty stomach at least 30 to 60 minutes before food. Separate the dose from other vitamins and certain medications (review with pharm) by 4 hours. Also be aware that Soybean flour, soy, grapefruit juice, espresso coffee, cottonseed meal, walnuts, dietary fiber may interfere with absorption of levothyroxine.
