Taking ZYVOX

What should I avoid while taking ZYVOX?

Large quantities of foods or beverages with high tyramine content should be avoided while taking ZYVOX. Foods high in tyramine content include those that may have undergone protein changes by aging, fermentation, pickling, or smoking to improve flavor, such as aged cheeses, fermented or air-dried meats, sauerkraut, soy sauce, tap beers, and red wines. The tyramine content of any protein-rich food may be increased if stored for long periods or improperly refrigerated.

How should I store my ZYVOX?

Store at 25°C (77°F). Protect from light and keep bottles tightly closed to protect from moisture.

What should I know about taking ZYVOX?

Antibacterial drugs including ZYVOX should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When ZYVOX is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by ZYVOX or other antibacterial drugs in the future.

Safety & Possible Side Effects

Top

Who should not take ZYVOX?

Do not take ZYVOX if you have a known hypersensitivity to linezolid or any of the other ingredients in ZYVOX.

Do not take ZYVOX if you are taking any monoamine oxidase inhibitors (MAOI) or within two weeks of taking an MAOI.

What are the most common side effects of ZYVOX?

The most common side effects include diarrhea, vomiting, headache, nausea, and anemia.

Diarrhea is a common problem caused by antibiotics, which usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, you should contact your physician as soon as possible.

What should I tell my doctor before taking ZYVOX?

Before you take ZYVOX tell your doctor about all your medical conditions, including:

  • If you have a history of hypertension
  • If you are taking medications containing pseudoephedrine HCl or phenylpropanolamine HCl, such as cold remedies and decongestants
  • If you are taking serotonin re-uptake inhibitors or other antidepressants
  • If you experience changes in vision
  • If you have a history of seizures
  • If you have diabetes mellitus
