Correct answer: ETake levothyroxine on an empty stomach and separate it from calcium supplements

Levothyroxine absorption can be reduced by calcium salts and by food. It is usually taken on an empty stomach at a consistent time, with separation from interacting supplements. Stopping calcium may not be necessary if timing can be adjusted. Weekly unsupervised dosing is not appropriate for routine administration.
