There are 3 alcohol/food/lifestyle interactions with levothyroxine which include:
Levothyroxine and multivitamins with minerals
Moderate Drug Interaction
Using multivitamin with minerals together with levothyroxine may decrease the effects of levothyroxine. You should separate the administration of levothyroxine and multivitamin with minerals by at least 4 hours. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate Food Interaction
The timing of meals relative to your levothyroxine dose can affect absorption of the drug. Therefore, levothyroxine should be taken on a consistent schedule with regard to time of day and relation to meals so as to maintain steady blood levels. In addition, absorption of levothyroxine may be decreased by foods such as soybean flour, cotton seed meal, walnuts, dietary fiber, calcium, and calcium fortified juices. These foods should be avoided within several hours of dosing if possible.
What this means is to follow directions carefully. Take the med half an hour before eating, in the morning with water only. This allows absorption. Then have a breakfast but don't take supplements until lunch or later during the day. Since calcium is the major problem, take it with dinner along with fortified juices and foods. Avoid soupy foods until lunch or later.
That is it and ask other questions as they come up. Karen
