Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.

While you are using ZYVOX, avoid taking an "SSRI" antidepressant without telling your doctor. This includes citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac, Sarafem), fluvoxamine (Luvox), paroxetine (Paxil), or sertraline (Zoloft). Taking an SSRI antidepressant together with ZYVOX can cause symptoms such as anxiety, high fever, sweating, chills or goosebumps, memory problems, trouble concentrating, loss of coordination, or muscle spasms.
Eating tyramine while you are taking ZYVOX can raise your blood pressure to dangerous levels. Avoid foods that have a high level of tyramine, such as:

*aged cheeses or meats;
*pickled or fermented meats;
*smoked or air-dried meats;
*sauerkraut;
*soy sauce;
*tap beer (alcoholic and nonalcoholic);
*red wine; or
*any meat, cheese, or other protein-based food that has been improperly stored.

You should become very familiar with the list of foods you must avoid while you are taking ZYVOX.
