IV (Adults): 1 mg/kg every 12 hr for 4–14 days. Concurrent use of strong CYP3A inducer– 1.5 mg/kg every 12 hr for 4–14 days.
IV (Adults): Severe hepatic impairment (Child-Pugh C)– 1 mg/kg every 12 hr on Day 1, then 1 mg/kg every 24 hr starting on Day 2 (total duration of therapy = 4–14 days).
Lyophilized powder for injection: 50 mg/vial, 100 mg/vial
- Assess for infection (vital signs, WBC) at beginning of and during therapy.
- Obtain specimens for culture and sensitivity before initiating therapy. First dose may be given before receiving results.
- Monitor bowel function. Diarrhea, abdominal cramping, fever, and bloody stools should be reported to health care professional promptly as a sign of Clostridioides difficile-associated diarrhea (CDAD). May begin up to several wk following cessation of therapy.
- Assess for signs and symptoms of hypersensitivity reactions (rash, hives, pruritus, dyspnea swelling of face, throat, and lips) during therapy.
- Assess IV site frequently; may cause thrombophlebitis.
- Intermittent Infusion: Reconstitution: Reconstitute each vial with 5 mL of Sterile Water for Injection or 0.9% NaCl. Concentration: 50 mg vial – 10 mg/mL. 100 mg vial – 20 mg/mL. Swirl gently until dissolved; do not shake. Solution is clear, pale yellow to orange solution. Reconstituted solution is stable for 1 hr; discard if not diluted within 1 hr. Dilution: Dilute further with 0.9% NaCl. Concentration: 0.3 mg/mL with a range of 0.2–0.6 mg/mL.Infuse within 24 hr if stored at room temperature or 10 days if refrigerated. Solution is clear, light yellow to orange; do not administer solutions that are cloudy, discolored or contain particulate matter.
- Rate: Infuse over 60 min. Flush line with 0.9% NaCl before and after infusion.
- Explain purpose of eravacycline to patient. Emphasize the importance of completing full course of therapy and not skipping doses.
- Instruct patient to notify health care professional immediately if rash, diarrhea, abdominal cramping, fever, or bloody stools occur and not to treat with antidiarrheals without consulting health care professionals. Diarrhea may occur as late as 2 mo after therapy.
- Caution patient to use sunscreen and protective clothing to prevent photosensitivity reactions.
- Advise patient to report the signs of superinfection (black, furry overgrowth on the tongue, vaginal itching or discharge, loose or foul-smelling stools).
- Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications.
- Rep: May cause tooth discoloration and inhibition of bone growth if administered during 2nd and 3rd trimesters. Advise females of reproductive potential to use a nonhormonal method of contraception while taking tetracyclines and until next menstrual period and to notify health care professional if pregnancy is planned or suspected and to avoid breastfeeding during and for 4 days after last dose of eravacycline. May cause infertility in male patients.
Resolution of the signs and symptoms of infection. Length of time for complete resolution depends on the organism and site of infection.
