Tobramycin

INDICATIONS AND USAGE Tobramycin is indicated for the treatment of serious bacterial infections caused by susceptible strains of the designated microorganisms in the diseases listed below: Septicemia in the neonate, child, and adult caused by P. aeruginosa , E. coli , and Klebsiella sp. Lower respiratory tract infections caused by P. aeruginosa , Klebsiella sp, Enterobacter sp, Serratia sp, E. coli , and S. aureus (penicillinase and non-penicillinase-producing strains). Serious central-nervous-system infections (meningitis) caused by susceptible organisms. Intra-abdominal infections, including peritonitis, caused by E. coli , Klebsiella sp, and Enterobacter sp. Skin, bone, and skin structure infections caused by P. aeruginosa , Proteus sp, E. coli , Klebsiella sp, Enterobacter sp, and S.

ADVERSE REACTIONS Neurotoxicity Adverse effects on both the vestibular and auditory branches of the eighth nerve have been noted, especially in patients receiving high doses or prolonged therapy, in those given previous courses of therapy with an ototoxin, and in cases of dehydration. Symptoms include dizziness, vertigo, tinnitus, roaring in the ears, and hearing loss. Hearing loss is usually irreversible and is manifested initially by diminution of high-tone acuity. Tobramycin and gentamicin sulfates closely parallel each other in regard to ototoxic potential.

WARNINGS Patients treated with Tobramycin for Injection, USP and other aminoglycosides should be under close clinical observation, because these drugs have an inherent potential for causing ototoxicity and nephrotoxicity. Neurotoxicity, manifested as both auditory and vestibular ototoxicity, can occur. The auditory changes are irreversible, are usually bilateral, and may be partial or total. WARNINGS See WARNINGS box above. This product contains sodium metabisulfite, a sulfite that may cause allergic-type reactions, including anaphylactic symptoms and life-threatening or less severe asthmatic episodes, in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people. Serious allergic reactions including anaphylaxis and dermatologic reactions including exfoliative dermatitis, toxic epidermal necrolysis, erythema multiforme, and Stevens Johnson Syndrome have been reported rarely in patients on tobramycin therapy. Although rare, fatalities have been reported. (See CONTRAINDICATIONS ). CONTRAINDICATIONS A hypersensitivity to any aminoglycoside is a contraindication to the use of tobramycin. A history of hypersensitivity or serious toxic reactions to aminoglycosides may also contraindicate the use of any other aminoglycoside because of the known cross-sensitivity of patients to drugs in this class.
