What is Sivextro?
From the FDA label:SIVEXTRO (tedizolid phosphate), a phosphate prodrug, is converted to tedizolid in the presence of phosphatases. Tedizolid phosphate has the chemical name [(5 R )-(3-{3-Fluoro-4-[6-(2-methyl-2 H -tetrazol- 5-yl) pyridin-3-yl]phenyl}-2-oxooxazolidin- 5-yl]methyl hydrogen phosphate. Its empirical formula is C 17 H 16 FN 6 O 6 P and its molecular weight is 450.32. Its structural formula is: Tedizolid phosphate is a white to yellow solid and is administered orally or by intravenous infusion. The pharmacologically active moiety, tedizolid, is an antibacterial agent of the oxazolidinone class. SIVEXTRO Tablets contain 200 mg of tedizolid phosphate, and the following inactive ingredients: crospovidone, magnesium stearate, mannitol, microcrystalline cellulose, and povidone. In addition, the film coating contains the following inactive ingredients: polyethylene glycol/macrogol, polyvinyl alcohol, talc, titanium dioxide, and yellow iron oxide. SIVEXTRO for Injection is a sterile, white to off-white sterile lyophilized powder supplied in a clear glass single-dose vial. Each vial contains 200 mg of tedizolid phosphate and the inactive ingredient, mannitol (105 mg). Sodium hydroxide and hydrochloric acid are used as needed for pH adjustment. When reconstituted as directed with 4 mL of Sterile Water for Injection, each mL contains 50 mg of tedizolid phosphate. The pH of the reconstituted…
How to use
Sivextro is sold in more than one form (Injectable and Tablet), and each is dosed differently. The instructions below come from the FDA label for application NDA205435 — follow the label that came with the product you were actually prescribed.

Side effects
The following clinically significant adverse reactions are described elsewhere in the labeling: Serotonin Syndrome [see Warnings and Precautions (5.1) ] Clostridioides difficile -Associated Diarrhea [see Warnings and Precautions (5.3) ] The most common adverse reactions (≥2%) in adult patients are nausea, headache, diarrhea, infusion- or injection-related adverse reactions, vomiting, and dizziness. ( 6.1 ) The most common adverse reactions (>2%) in pediatric patients (12 years to less than 18 years of age) are phlebitis and increased hepatic transaminases. ( 6.1 ) The most common adverse reactions (>2%) in pediatric patients (less than 12 years of age) are infusion- or injection-related adverse reactions and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Merck Sharp & Dohme LLC at 1-877-888-4231 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be compared directly to rates from clinical trials of another drug and may not reflect rates observed in practice. Clinical Trials Experience in Adult Patients Adverse reactions were evaluated for 1425 adult patients treated with SIVEXTRO in two Phase 2 and four Phase 3 clinical trials (three Phase 3 trials for 6 days of therapy and one Phase 3 trial…
Warnings
Important safety information
Serotonin Syndrome: Monitor patients taking SIVEXTRO concomitantly with serotonergic agents for signs of serotonin syndrome. If signs or symptoms of serotonin syndrome occur, consider discontinuing SIVEXTRO and/or concomitant serotonergic agents. ( 5.1 ) Patients with neutropenia: The safety and efficacy of SIVEXTRO in patients with neutropenia (neutrophil counts <1000 cells/mm 3 ) have not been adequately evaluated. In an animal model of infection, the antibacterial activity of SIVEXTRO was reduced in the absence of granulocytes. Consider alternative therapies in neutropenic patients. ( 5.2 ) Clostridioides difficile -Associated Diarrhea: Evaluate if diarrhea occurs. ( 5.3 ) 5.1 Serotonin Syndrome Spontaneous reports of serotonin syndrome have been observed with the co-administration of oxazolidinones, including SIVEXTRO, and serotonergic agents. Commonly used serotonergic agents include serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants, buspirone, serotonin 5-HT1 receptor agonists (triptans), and opioids, including meperidine. Symptoms associated with serotonin syndrome may include hyperthermia, diaphoresis, agitation, hyperreflexia, clonus, pyrexia, opsoclonus, muscle rigidity, tremor, and hypertonia. Monitor patients for the emergence of serotonin syndrome with the concomitant use of SIVEXTRO and serotonergic agents. If signs or symptoms of serotonin syndrome occur, consider discontinuing SIVEXTRO and/or concomitant serotonergic agents as clinically appropriate and initiate supportive treatment. Inform patients of the increased risk of serotonin syndrome when SIVEXTRO is used concomitantly with serotonergic agents. 5.2 Patients with Neutropenia The safety and efficacy of SIVEXTRO in patients with neutropenia (neutrophil counts <1000 cells/mm 3 ) have not been adequately evaluated. In an animal model of infection, the antibacterial activity of SIVEXTRO was reduced in the absence of granulocytes [see Clinical Pharmacology (12.2) ] . Alternative therapies should be considered when treating patients with neutropenia and ABSSSI. 5.3 Clostridioides difficile -Associated Diarrhea Clostridioides difficile -associated diarrhea (CDAD) has been reported for nearly all systemic antibacterial agents including SIVEXTRO, with severity ranging from mild diarrhea to fatal colitis. Treatment with antibacterial agents can alter the normal flora of the colon and may permit overgrowth of C. difficile . C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antibacterial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary because CDAD has been reported to occur more than two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, antibacterial use not directed against C. difficile should be discontinued, if possible. Appropriate measures such as fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated. 5.4 Development of Drug-Resistant Bacteria Prescribing SIVEXTRO in the absence of a proven or strongly suspected bacterial infection or prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
Who should not take Sivextro
None. None ( 4 )
Overdose — what happens if you take too much
In the event of overdosage, SIVEXTRO should be discontinued and general supportive treatment given. Hemodialysis does not result in meaningful removal of tedizolid from systemic circulation.

Interactions
SIVEXTRO (when administered orally) can increase the plasma concentrations of orally administered Breast Cancer Resistance Protein (BCRP) substrates. Monitor for adverse reactions related to the concomitant BCRP substrates if coadministration cannot be avoided. ( 7 , 12.3 ) SIVEXTRO has the potential for interaction with serotonergic agents. ( 5.1 , 7 ) 7.1 Membrane Transporters Orally administered SIVEXTRO inhibits Breast Cancer Resistance Protein (BCRP) in the intestine, which can increase the plasma concentrations of orally administered BCRP substrates, and the potential for adverse reactions. If possible, an interruption in the treatment of the co-administered BCRP substrate medicinal product should be considered during treatment with SIVEXTRO, especially for BCRP substrates with a narrow therapeutic index (e.g., methotrexate or topotecan). If coadministration cannot be avoided, monitor for adverse reactions related to the concomitantly administered BCRP substrates, including rosuvastatin [see Clinical Pharmacology (12.3) ]. 7.2 Serotonergic Agents In postmarketing experience, there have been reports of serotonin syndrome in patients taking SIVEXTRO with serotonergic agents [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ] .
