Brand Name(s): Zyvox^®

WHY is this medicine prescribed?

Linezolid is used to treat infections, including pneumonia, and infections of the skin . Linezolid is in a class of antibacterials called oxazolidinones. It works by stopping the growth of bacteria.

Antibiotics such as linezolid will not work for colds, flu, and other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Are there OTHER USES for this medicine?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Linezolid comes as a tablet and oral suspension (liquid) to take by mouth. It is usually taken with or without food twice a day (every 12 hours) for 10 to 28 days. Children 11 years of age and younger usually take linezolid with or without food two to three times a day (every 8 to 12 hours) for 10 to 28 days. The length of your treatment depends on the type of infection you have. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take linezolid exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Before using the oral suspension, gently mix it by turning over the bottle three to five times. Do not shake the suspension.

Take linezolid until you finish the prescription, even if you feel better. Do not stop taking linezolid without talking to your doctor. If you stop taking linezolid too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from light and excess heat and moisture (not in the bathroom). Linezolid oral suspension should be used within 21 days.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. https://www.upandaway.org
