Can you take methadone and Levaquin?

Levaquin, I know can be taken and is given by some medical doctors for specific conditions such as bronchitis, pneumonia. etc. I have been told it is a dangerous drug and should only be used under the care of your personal physician and one should follow the directions just as he gives them..I am less familiar with methadone; it is a synthetic drug used to treat addiction. Both can be taken orally.
