Inhibits protein translation in bacteria by binding to 30S ribosomal subunit and blocking entry of amino-acyl tRNA molecules into ribosomal A site, which in turn prevents incorporation of amino acid residues into elongating peptide chains
Powder for injection (lyophilized): 50 mg/5 ml in single-dose vial
⊘Indications and dosages
➣ Treatment of skin, skin-structure infections, and complicated intra-abdominal infections caused by susceptible organisms
Adults age 18 and older: 100 mg I.V. initially, followed by 50 mg I.V. every 12 hours for 5 to 14 days, depending on infection site and severity and patient's clinical and bacteriologic process
➣ Community-acquired bacterial pneumonia caused by susceptible organisms
Adults age 18 and older: Initially, 100 mg I.V., followed by 50 mg I.V. q 12 hours for 7 to 14 days, depending on infection site and severity and patient's clinical and bacteriologic process
• Severe hepatic impairment
• Hypersensitivity to drug or its components
Use cautiously in:
• mild to moderate hepatic impairment, complicated intra-abdominal infections secondary to perforation, ventilator-associated pneumonia
• pregnant and breastfeeding patients
• children younger than age 18.
• Reconstitute with 5.3 ml of normal saline solution injection or 5% dextrose injection to yield a concentration of 10 mg/ml (50 mg).
• Swirl vial gently until drug dissolves. Immediately withdraw 5 ml of reconstituted solution from vial and add to 100-ml I.V. bag for infusion. Maximum concentration in I.V. bag should be 1 mg/ml.
• Discard reconstituted solution that isn't yellow or orange.
• Administer through dedicated I.V. line or Y-site. If same I.V. line is used for sequential infusion of several drugs, flush before and after infusion, using either normal saline solution injection or 5% dextrose injection. Use infusion solution compatible with tigecycline and other drugs given through same line.
• Administer over 30 to 60 minutes.
• Don't give amphotericin B, chlorpromazine, methylprednisolone, or voriconazole simultaneously through same Y-site.

Hepatic ImpairmentIntravenous (Adults >18 yr) Child-Pugh C—100 mg initially, then 25 mg every 12 hr.
- Assess for infection (vital signs; appearance of wound, sputum, urine, and stool; WBC) at beginning of and throughout therapy.
- Obtain specimens for culture and sensitivity before initiating therapy. 1st dose may be given before receiving results.
- Before initiating therapy, obtain a history of tetracycline hypersensitivity; may also have an allergic response to tigecycline.
- Monitor bowel function. Diarrhea, abdominal cramping, fever, and bloody stools should be reported to health care professional promptly as a sign of pseudomembranous colitis. May begin up to several weeks following cessation of therapy.
- Assess patient for signs of pancreatitis (nausea, vomiting, abdominal pain, increased serum lipase or amylase) periodically during therapy. May require discontinuation of therapy.
- Assess for rash periodically during therapy. May cause Stevens-Johnson syndrome. Discontinue therapy if severe or if accompanied with fever, general malaise, fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, hepatitis and/or eosinophilia.
- Lab Test Considerations: May cause anemia, leukocytosis, and thrombocythemia.
- May cause ↑ serum alkaline phosphatase, amylase, bilirubin, LDH, AST, and ALT.
- May cause hyperglycemia, hypokalemia, hypoproteinemia, hypocalcemia, hyponatremia, and ↑ BUN level.
Potential Nursing DiagnosesRisk for infection (Indications)
- May cause yellow-brown discoloration and softening of teeth and bones if administered prenatally or during early childhood. Not recommended for children under 8 yr of age or during pregnancy or lactation unless used for the treatment of anthrax.
- Intermittent Infusion: Reconstitute each vial with 5.3 mL of 0.9% NaCl or D5W to achieve a concentration of 10 mg/mL. Diluent: Dilute further in 100 mL of D5W, LR, or 0.9% NaCl. Reconstituted solution should be yellow to orange in color. Do not administer solutions that are discolored or contain particulate matter. Infusion is stable for up to 24 hr at room temperature or for up to 48 hr if refrigerated.Concentration: Final concentration of infusion should be ≤1 mg/mL.
- Rate: Infuse over 30–60 min. Flush line before and after infusion with 0.9% NaCl or D5W.
