Tobramycin injection 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. …

• Tobramycin may be given intramuscularly or intravenously
• Recommended dosages are the same for both routes
• This insert is for a Pharmacy Bulk Package and is intended for preparing I.V. admixtures only
• Dosage recommendations for intramuscular use are for informational purposes only
• The patient’s pretreatment body weight should be obtained for calculation of correct dosage
• It is desirable to measure both peak and trough serum concentrations (see WARNINGS box and PRECAUTIONS )
• Administration for Patients with Normal Renal Function— Adults with Serious Infections : 3 mg/kg/day in 3 equal doses every 8 hours (see Table 3)
• Adults with Life-Threatening Infections : Up to 5 mg/kg/day may be administered in 3 or 4 equal doses (see Table 3)
• The dosage should be reduced to 3 mg/kg/day as soon as clinically indicated
• To prevent increased toxicity due to excessive blood levels, dosage should not exceed 5 mg/kg/day unless serum levels are monitored (see WARNINGS box and PRECAUTIONS ). …

• 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

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 non-asthmatic 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. …

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. …

Signs and Symptoms— The severity of the signs and symptoms following a tobramycin overdose are dependent on the dose administered, the patient’s renal function, state of hydration, and age and whether or not other medications with similar toxicities are being administered concurrently. Toxicity may occur in patients treated more than 10 days, in adults given more than 5 mg/kg/day, children given more than 7.5 mg/kg/day, or patients with reduced renal function whose dose has not been appropriately adjusted. …
