Capreomycin is a cyclic polypeptide antimicrobial. It is administered as a mixture of capreomycin IA and capreomycin IB. The mechanism of action of capreomycin is not well understood. Mycobacterial species that have become resistant to other agents are usually still sensitive to the action of capreomycin. However, significant cross-resistance with viomycin, kanamycin, and neomycin occurs.

Frequency not always defined.
Otic: Ototoxicity (subclinical hearing loss: 11%; clinical loss: 3%)
Genitourinary: Nephrotoxicity (36%, increased blood urea nitrogen)
1% to 10%: Hematologic: Eosinophilia (dose-related, mild)
<1% (Limited to important or life-threatening): Hepatic insufficiency (decreased sulfobromophthalein excretion), hypersensitivity (includes fever, maculopapular rash, urticaria), hypocalcemia, hypokalemia, hypomagnesemia, increased serum creatinine, injection site reaction (includes abscess at injection site, bleeding at injection site, induration at injection site, and pain at injection site), leukocytosis, leukopenia, nephritis (toxic), renal tubular necrosis, thrombocytopenia (rare), tinnitus, urine sedimentation abnormality, vertigo
Concerns related to adverse effects:
• Electrolyte imbalance: Hypocalcemia, hypokalemia, and hypomagnesemia have been reported with use. Monitor electrolytes periodically during treatment.
• Nephrotoxicity: May cause nephrotoxicity, including tubular necrosis, increased BUN or serum creatinine, and abnormal urinary sediment; slight elevations in BUN and serum creatinine with urinary RBCs, WBCs, and casts have been observed with prolonged treatment. Monitor renal function at baseline and periodically during treatment. A BUN >30 mg/dL or other evidence of decreasing renal function should prompt clinical evaluation and dosage adjustment or therapy discontinuation.
• Ototoxicity: May cause impairment of cranial nerve VIII, which may be irreversible; perform audiometric assessment and assessment of vestibular function prior to initiation and periodically during treatment.
• Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
• Allergies: Use with caution in patients who demonstrate some form of allergy.
• Auditory impairment: [US Boxed Warning]: Use in patients with preexisting auditory impairment must be undertaken with great caution, and the risk of additional cranial nerve VIII impairment should be weighed against the benefits to be derived from therapy.
• Renal impairment: [US Boxed Warning]: Use in patients with renal impairment must be undertaken with great caution, and the risk of additional renal injury should be weighed against the benefits to be derived from therapy. Dosage reductions are recommended for known or suspected renal impairment.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Drugs with ototoxic or nephrotoxic potential: [US Boxed Warning]: Use with nonantituberculous drugs (eg, polymyxin A sulfate, colistin sulfate, gentamicin, tobramycin, vancomycin, neomycin) having ototoxic or nephrotoxic potential should be undertaken only with great caution.
• Parenteral antituberculous agents: [US Boxed Warning]: Because other parenteral antituberculous agents (eg, streptomycin, viomycin) also have similar and sometimes irreversible toxic effects, particularly on cranial nerve VIII and renal function, simultaneous administration of these agents with capreomycin is not recommended.
• Elderly: Use with caution.
• Pediatric: [US Boxed Warning]: Safety has not been established in pediatric patients.
• Pregnancy: [US Boxed Warning]: Safety has not been established in pregnant women.
Audiometric measurements and vestibular function at baseline and during therapy; renal function at baseline and weekly during therapy; baseline and frequent assessment of serum electrolytes (including calcium, magnesium, and potassium), liver function tests
Pregnancy Risk Factor
Adverse events have been reported in animal reproduction studies. [US Boxed Warning]: Safety has not been established in pregnant women; avoid use during pregnancy because of the risk of fetal nephrotoxicity and congenital hearing loss (MMWR 2003).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Have patient report immediately to prescriber signs of electrolyte problems (mood changes, confusion, muscle pain or weakness, abnormal heartbeat, seizures, lack of appetite, or severe nausea or vomiting), signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), severe dizziness, muscle weakness, chills, pharyngitis, hearing impairment, tinnitus, or injection site pain, redness, edema, or irritation (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
