Sivextro (tedizolid) is an oxazolidinone antibiotic. It works by stopping an enzyme (a protein) that's needed to make proteins in bacterial cells from working. This prevents bacteria from being able to grow and survive.

You can take Sivextro (tedizolid) with or without food. If it's upsetting your stomach, try taking it with food to help.
If you develop watery or bloody diarrhea, fever, fatigue, or stomach cramps anytime during treatment or after stopping Sivextro (tedizolid), get medical help right away because these could be signs of a type of infectious diarrhea, which needs to be treated right away.
If you experience diarrhea from taking Sivextro (tedizolid), let your provider know. If they think the diarrhea isn't too serious, they might recommend that you take a probiotic to help lessen this side effect. If so, make sure to separate the probiotic from Sivextro (tedizolid) by at least 2 hours to prevent Sivextro (tedizolid) from killing the "good" bacteria in the probiotic.
Take Sivextro (tedizolid) exactly as prescribed. Make sure to finish your treatment course, even if you're feeling better. Stopping the medication earlier than prescribed can make your infection come back and become harder to treat.
If you miss a dose of Sivextro (tedizolid), take it as soon as you remember if there's at least 8 hours until your next scheduled dose. If your next dose is due in less than 8 hours, just skip the missed dose. Take your next dose at your regularly scheduled time. Don't take two doses to make up for the missed dose.
Sivextro (tedizolid) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Sivextro (tedizolid) can raise your risk of getting infected with a bacteria called Clostridioides difficile (C. diff). This infection can cause severe diarrhea. In general, you have "good bacteria" in your gut that keeps the "bad bacteria," like C. diff, in check. But antibiotics, like Sivextro (tedizolid), can change the typical make-up of your gut bacteria. As a result, C. diff can overgrow in your gut and lead to an infection. Infectious diarrhea can cause rapid heart rate, foul-smelling diarrhea, fever, nausea, frequent bowel movements (even up to 15 times per day) and is considered an emergency. If you have any of these symptoms, get medical attention immediately so you can get tested for C. diff infection and receive treatment.
Take Sivextro (tedizolid) exactly as prescribed. Taking Sivextro (tedizolid) for any shorter or longer periods of time or taking the antibiotic for other illnesses can raise your risk for developing infections caused by bacteria that's hard to treat with antibiotics. This raises your risk for severe and life-threatening infections that might be difficult to treat.
The typical dose is 200 mg by mouth or injected into the veins (IV) once daily for 6 days. If you're receiving Sivextro (tedizolid) IV, it'll be given to you by a healthcare provider, typically in a hospital or a clinic setting.
