Zyvox is an antibiotic that was originally approved by the FDA in April of 2000. It is used to treat bacterial infections in adults. As such, it is not designed to treat viral infections such as the common cold.
As with any medication, there are certain precautions that should be taken to avoid unhappy consequences. For instance, if a patient happens to be afflicted with Phenylketonuria (a genetic disorder in which the body lacks the enzyme to convert phenylalanine hydroxylase to tyrosine) should not take the oral suspension for of the medicine as it contains phenylalanine as a part of aspartame. The other forms of the medicine (tablets and injections) do not contain aspartame and so are safe. All individuals using Zyvox should not eat foods high in tryamine.
The serious side effects associated with taking Zyvox all involve a decrease in the parts of the blood including platelets, white blood cells, and red blood cells. The minor side effects of Zyvox are diarrhea, headache, and nausea.
In March of 2007, the FDA reported that in a study of patients with catheter-related bloodstream infections, patients using Zyvox, or linezeloid, had a higher chance of death than did patients using other antibiotics designed to fight bacterial infections.
