The IV formulation is given to you by a healthcare professional. The oral tablets should be swallowed whole - don't cut, crush, or chew them. If you have difficulty swallowing pills, your prescriber may have you take the oral suspension.
The oral liquid will be prepared for you by a pharmacist. They will instruct you on how much liquid to take for each dose. Don't shake the bottle before use. Instead, gently invert it 3 to 5 times. Store the medication at room temperature, and use it within 3 weeks.
What's the typical Zyvox dosage for adults?
The Zyvox dosage for adults depends on the infection being treated. The dosages detailed below are recommended by the manufacturer. It's possible that your prescriber may have you take Zyvox differently. Keep in mind that you should finish the entire course of Zyvox, even if you're feeling better.
Pneumonia
Zyvox is approved to treat pneumonia, whether it was acquired in a healthcare setting (nosocomial pneumonia) or outside a healthcare setting (community-acquired pneumonia). The typical Zyvox dosage for pneumonia in adults is 600 mg by mouth or IV infusion every 12 hours for 10 to 14 days.
Skin infections
Zyvox is approved to treat uncomplicated and complicated skin infections. The typical Zyvox dosage for uncomplicated skin infections in adults is 400 mg by mouth every 12 hours. For complicated skin infections, the dosage is 600 mg by mouth or IV infusion every 12 hours. The treatment course for skin infections is usually 10 to 14 days.
Enterococcal infections
Enterococcus bacteria can cause serious infections. Zyvox is used to treat enterococcal infections that are resistant to another antibiotic called vancomycin. Vancomycin-resistant Enterococci (VRE) infections typically require a longer Zyvox treatment duration. The usual adult dosage is 600 mg by mouth or IV infusion every 12 hours for 14 to 28 days.
What's the typical Zyvox dosage for children?
The Zyvox dosage for children depends on the child's age and body weight. Since there are more factors to consider with children, we'll look at the dosages in easy-to-read charts.

Are there dosage adjustments for health conditions or interactions?
There are no dosage adjustments recommended if you have kidney problems. But if you regularly receive dialysis, your prescriber may advise you to take Zyvox after dialysis. If you have severe kidney damage, you may be more likely to have certain side effects.
Zyvox dosage adjustments are also not recommended if you have mild or moderate liver impairment. But you may be more likely to experience certain side effects if you have moderate to severe liver damage.
Zyvox has a number of serious interactions, including medications and foods. Ensure your healthcare team has your medication list to check for these. They can use that information to help determine if Zyvox is a good choice for you.
What happens if you miss a dose of Zyvox?
Zyvox is used to treat serious infections. If you don't take it as prescribed, such as missing doses or stopping it early, your infection may not be adequately treated. Your infection could come back and be harder to treat.
But if you forget to take a Zyvox dose, take it as soon as you remember. If it's almost time for your next dose, skip the dose you missed - don't double up your dose. Ask a healthcare professional about instructions for missed doses.
If you have any trouble remembering to take Zyvox, try a medication adherence tool, such as calendar alerts or a medication reminder app.
What should you do if you take too much Zyvox?
Taking too much Zyvox may put you at increased risk of serious side effects. These can include serotonin syndrome (too much serotonin in the body) or low blood counts. Symptoms of serotonin syndrome include sweating, tremors (shakiness), and a fast heartbeat.
If you may have taken too much Zyvox, contact your prescriber right away. You can also call Poison Control at 1-800-222-1222. Go to the ER if symptoms feel severe or life-threatening.
