A member asked:

The inside of my mouth and tongue turn black when taking minocycline, doxycycline, and trazodone? i don't necessarily have to take them simultaneously or even days apart. i can take them just one time and my mouth becomes noticeably discolored. why?

These are broad spectrum antibiotics and change the normal flora of the mouth that may result in what is called “black hairy tongue”. Usually after several days. Consult your primary care for change and possible culture.
