SIVEXTRO® is an oxazolidinone-class antibacterial indicated in adult and pediatric patients 12 years of age and older for the treatment of acute bacterial skin and skin structure infections (ABSSSI) caused by susceptible isolates of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-resistant [MRSA] and methicillin-susceptible [MSSA] isolates), Streptococcus pyogenes , Streptococcus agalactiae , Streptococcus anginosus Group (including Streptococcus anginosus , Streptococcus intermedius , and Streptococcus constellatus), and Enterococcus faecalis .
To reduce the development of drug-resistant bacteria and maintain the effectiveness of SIVEXTRO and other antibacterial drugs, SIVEXTRO should be used only to treat ABSSSI that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
The recommended dosage of SIVEXTRO is 200 mg administered once daily for six (6) days either orally (with or without food) or as an intravenous (IV) infusion in patients 12 years of age or older.
The recommended dosage and administration of SIVEXTRO are described in Table 1.
|Infection||Route||Dosage||Frequency||Infusion Time||Duration of Treatment|
|Acute Bacterial Skin and Skin Structure Infections (ABSSSI)||Intravenous||200 mg||Once daily||1 hour||6 days|
|Oral||200 mg||Once daily||Not Applicable|
No dose adjustment is necessary when changing from intravenous to oral SIVEXTRO.
If patients miss a dose, they should take it as soon as possible anytime up to 8 hours prior to their next scheduled dose. If less than 8 hours remain before the next dose, wait until their next scheduled dose.
SIVEXTRO is supplied as a sterile, lyophilized powder for injection in single-dose vials of 200 mg. Each 200 mg vial must be reconstituted with Sterile Water for Injection and subsequently diluted only with 0.9% Sodium Chloride Injection, USP.
SIVEXTRO vials contain no antimicrobial preservatives and are intended for single dose only. Discard any unused portion.
The contents of the vial should be reconstituted using aseptic technique as follows:
Note: To minimize foaming, AVOID vigorous agitation or shaking of the vial during or after reconstitution.
- Reconstitute the SIVEXTRO vial with 4 mL of Sterile Water for Injection.
- Gently swirl the contents and let the vial stand until the cake has completely dissolved and any foam disperses.
- Inspect the vial to ensure the solution contains no particulate matter and no cake or powder remains attached to the sides of the vial. If necessary, invert the vial to dissolve any remaining powder and swirl gently to prevent foaming. The reconstituted solution is clear and colorless to pale-yellow in color; the total storage time should not exceed 24 hours at either room temperature or under refrigeration at 2°C to 8°C (36°F to 46°F).
- Tilt the upright vial and insert a syringe with appropriately sized needle into the bottom corner of the vial and remove 4 mL of the reconstituted solution. Do not invert the vial during extraction.
- The reconstituted solution must be further diluted in 250 mL of 0.9% Sodium Chloride Injection, USP. Slowly inject the 4 mL of reconstituted solution into a 250 mL bag of 0.9% Sodium Chloride Injection, USP. Invert the bag gently to mix. Do NOT shake the bag as this may cause foaming.
Administer as an intravenous infusion only.
Do not administer as an intravenous push or bolus. Do not mix SIVEXTRO with other drugs when administering. It is not intended for intra-arterial, intramuscular, intrathecal, intraperitoneal, or subcutaneous administration.
The intravenous bag containing the reconstituted and diluted intravenous solution should be inspected visually for particulate matter prior to administration. Discard if visible particles are observed. The resulting solution is clear and colorless to pale-yellow in color.
After reconstitution and dilution, SIVEXTRO is to be administered via intravenous infusion using a total time of 1 hour.
The total time from reconstitution to administration should not exceed 24 hours at room temperature or under refrigeration at 2°C to 8°C (36°F to 46°F).
Discard unused portion.
SIVEXTRO is compatible with 0.9% Sodium Chloride Injection, USP.
SIVEXTRO for injection is incompatible with any solution containing divalent cations (e.g., Ca2+ , Mg2+), including Lactated Ringer’s Injection and Hartmann’s Solution.
Limited data are available on the compatibility of SIVEXTRO for injection with other intravenous substances, additives or other medications and they should not be added to SIVEXTRO single-dose vials or infused simultaneously. If the same intravenous line is used for sequential infusion of several different drugs, the line should be flushed before and after infusion of SIVEXTRO with 0.9% Sodium Chloride Injection, USP.
SIVEXTRO 200 mg tablet is a yellow film-coated oval tablet; each tablet is debossed with “TZD” on one side and “200” on the other side.
SIVEXTRO for injection is a sterile, white to off-white lyophilized powder for injection in single-dose vials of 200 mg. Each 200 mg vial must be reconstituted with Sterile Water for Injection and subsequently diluted only with 0.9% Sodium Chloride Injection, USP.
The safety and efficacy of SIVEXTRO in patients with neutropenia (neutrophil counts <1000 cells/mm3) 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.
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.
