Hypersensitivity to eravacycline, tetracycline-class antibacterial drugs, or any component of the formulation.

Dosing: Adult

Intra-abdominal infections, complicated: IV: 1 mg/kg every 12 hours for 4 to 14 days

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Dosing: Geriatric

Refer to adult dosing.


Reconstitute each vial with 5 mL NS or SWFI to a concentration of 10 mg/mL (50 mg vial) or 20 mg/mL (100 mg vial). Swirl gently; avoid shaking, which may cause foaming. Do not use if solution is cloudy or has visible particles. Reconstituted solution must be further diluted to allow for IV administration. Transfer full or partial vial contents to an IV bag of NS to a final concentration of 0.3 mg/mL (within a range of 0.2 to 0.6 mg/mL). Do not shake the bag. Reconstituted solution should be clear, yellow to orange color.


IV: Infuse diluted solution IV over ~60 minutes through dedicated line or via Y-site. If the same IV line is used for sequential infusion of several drugs, flush line with NS before and after eravacycline administration. Do not mix with other drugs or add to solutions containing other drugs.


Store intact vials in original carton at 2°C to 8°C (36°F to 46°F). Reconstituted vial may be stored at room temperature (≤25°C [77°F]) but must be further diluted within 1 hour. Diluted solutions for infusion may be stored at room temperature (≤25°C [77°F]) for up to 24 hours or refrigerated (2°C to 8°C [36°F to 46°F]) for up to 10 days. Do not freeze.

Drug Interactions

Aminolevulinic Acid (Systemic): Photosensitizing Agents may enhance the photosensitizing effect of Aminolevulinic Acid (Systemic). Avoid combination

Aminolevulinic Acid (Topical): Photosensitizing Agents may enhance the photosensitizing effect of Aminolevulinic Acid (Topical). Monitor therapy

BCG (Intravesical): Antibiotics may diminish the therapeutic effect of BCG (Intravesical). Avoid combination

BCG Vaccine (Immunization): Antibiotics may diminish the therapeutic effect of BCG Vaccine (Immunization). Monitor therapy

Cholera Vaccine: Antibiotics may diminish the therapeutic effect of Cholera Vaccine. Management: Avoid cholera vaccine in patients receiving systemic antibiotics, and within 14 days following the use of oral or parenteral antibiotics. Avoid combination

CYP3A4 Inducers (Strong): May decrease the serum concentration of Eravacycline. Management: Increase the eravacycline dose to 1.5 mg/kg every 12 hours when combined with strong CYP3A4 inducers. Consider therapy modification

Lactobacillus and Estriol: Antibiotics may diminish the therapeutic effect of Lactobacillus and Estriol. Monitor therapy

Lithium: Tetracyclines may increase the serum concentration of Lithium. Monitor therapy

Mecamylamine: Tetracyclines may enhance the neuromuscular-blocking effect of Mecamylamine. Avoid combination

Methoxyflurane: Tetracyclines may enhance the nephrotoxic effect of Methoxyflurane. Avoid combination

Mipomersen: Tetracyclines may enhance the hepatotoxic effect of Mipomersen. Monitor therapy

Neuromuscular-Blocking Agents: Tetracyclines may enhance the neuromuscular-blocking effect of Neuromuscular-Blocking Agents. Monitor therapy

Penicillins: Tetracyclines may diminish the therapeutic effect of Penicillins. Monitor therapy

Porfimer: Photosensitizing Agents may enhance the photosensitizing effect of Porfimer. Monitor therapy

Retinoic Acid Derivatives: Tetracyclines may enhance the adverse/toxic effect of Retinoic Acid Derivatives. The development of pseudotumor cerebri is of particular concern. Avoid combination

Sodium Picosulfate: Antibiotics may diminish the therapeutic effect of Sodium Picosulfate. Management: Consider using an alternative product for bowel cleansing prior to a colonoscopy in patients who have recently used or are concurrently using an antibiotic. Consider therapy modification

Typhoid Vaccine: Antibiotics may diminish the therapeutic effect of Typhoid Vaccine. Only the live attenuated Ty21a strain is affected. Management: Avoid use of live attenuated typhoid vaccine (Ty21a) in patients being treated with systemic antibacterial agents. Postpone vaccination until 3 days after cessation of antibiotics and avoid starting antibiotics within 3 days of last vaccine dose. Consider therapy modification

Adverse Reactions

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified.

1% to 10%:

Cardiovascular: Hypotension (1%)

Gastrointestinal: Nausea (7%), vomiting (4%), diarrhea (2%)

Local: Infusion site reaction (8%)

Miscellaneous: Wound dehiscence (1%)

<1%, postmarketing, and/or case reports: Acute pancreatitis, anaphylaxis, anxiety, chest pain, decreased creatinine clearance, decreased white blood cell count, depression, dizziness, dysgeusia, dyspnea, hyperhidrosis, hypersensitivity reaction, hypocalcemia, increased amylase, increased gamma-glutamyl transferase, increased serum alanine aminotransferase, increased serum lipase, insomnia, neutropenia, palpitations, pancreatic necrosis, pleural effusion, prolonged partial thromboplastin time, skin rash


Concerns related to adverse effects:

• Anaphylactic/Hypersensitivity reactions: Life-threatening (anaphylactic) reactions have been reported; discontinue if an allergic reaction occurs. Avoid use in patients with known hypersensitivity to tetracyclines.

• Antianabolic effects: May be associated with antianabolic effects observed with the tetracycline class (including increased BUN, azotemia, acidosis, and hyperphosphatemia).

• Hepatotoxicity: May be associated with abnormal liver function tests due to structural similarities with tetracyclines; discontinue use when suspected.

• Pancreatitis: May be associated with pancreatitis due to structural similarities with tetracyclines.

• Photosensitivity: May be associated with photosensitivity due to structural similarities with tetracyclines.

• Pseudotumor cerebri: May be associated with pseudotumor cerebri due to structural similarities with tetracyclines.

• Superinfection: Use may result in fungal or bacterial superinfection, including Clostridioides (formerly Clostridium) difficile infection (CDI) and colitis; CDI has been observed >2 months postantibiotic treatment.

Disease-related concerns:

• Hepatic impairment: Use with caution in patients with hepatic impairment; dosage adjustment recommended in severe hepatic impairment.

Special populations:

• Pediatric: May cause permanent tooth discoloration, enamel hypoplasia, or reversible inhibition of bone growth; use should be avoided during tooth and bone development (children <8 years of age).

Other warnings/precautions:

• Limitations of use: Not indicated for the treatment of complicated urinary tract infection in adults; eravacycline failed to demonstrate efficacy in 2 randomized, double-blind, active-controlled clinical trials.

Monitoring Parameters

Monitor hepatic function periodically. Observe for signs and symptoms of anaphylaxis during administration.

Pregnancy Considerations

Tetracyclines cross the placenta.

As a class, tetracyclines accumulate in developing teeth and long tubular bones (Mylonas 2011). Exposure during the second and third trimesters of pregnancy may cause reversible inhibition of bone growth. Permanent discoloration of teeth (yellow, gray, brown) can occur following in utero exposure and is more likely to occur following long-term or repeated exposure.
