Zyvox (Linezolid)

This medicine is an oxazolidinone antibiotic used to treat certain serious bacterial infections that are often resistant to other antibiotics.

Follow the directions for using this medicine provided by your doctor. This medicine may be taken on an empty stomach or with food. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. Continue to take this medication until the full-prescribed amount is finished even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a relapse of the infection. Inform your doctor if your condition does not improve in 10 days.

Zyvox is related to a group of drugs called MAO inhibitors.

If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.
