Note: This document contains side effect information about capreomycin. Some dosage forms listed on this page may not apply to the brand name Capastat.

Applies to capreomycin: injection powder for solution.


Injection route (Powder for Solution)

The use of capreomycin in patients with renal insufficiency or preexisting auditory impairment must be undertaken with great caution, and the risk of additional cranial nerve VIII impairment or renal injury should be weighed against the benefits to be derived from therapy. Since other parenteral antituberculosis agents (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. Use with nonantituberculosis drugs (polymyxin A sulfate, colistin sulfate, amikacin, gentamicin, tobramycin, vancomycin, kanamycin, and neomycin) having ototoxic or nephrotoxic potential should be undertaken only with great caution. The safety of the use of capreomycin in pregnancy has not been determined. Safety and effectiveness in pediatric patients have not been established.
