[Outline]
- Streptomycin can cause severe neurotoxicity and ototoxicity. The degree of impairment of vestibular and auditory function is proportional to the dose and duration of therapy, age of the patient, level of renal function and underlying existing auditory dysfunction
- Select dosage regimen carefully in patients with renal impairment. Risk of ototoxicity and neurotoxicity increases with renal impairment
- Do not exceed recommended dosage
- Streptomycin can cause fetal harm if administered to a pregnant woman. It crosses placental barrier and may cause ototoxicity in the fetus
- Stretomycin is for IM use only. Inject in a large muscle, preferred site is the upper outer quadrant of the buttock, (i.e., gluteus maximus), or the mid-lateral thigh
- Monitor BUN/Cr at baseline, then periodically
- Monitor serum drug levels; urinalysis; audiometry for high risk patients or if prolonged tx or if symptoms of hearing impairment
Cautions: Use cautiously in
- Renal impairment (blood level monitoring recommended due to risk of ototoxicity and nephrotoxicity)
- Neuromuscular disease (eg myasthenia gravis)
- Impaired vestibular function
- Impaired auditory function
- Concurrent ototoxic agents
- Concurrent neurotoxic agents
- Dehydration
- Concurrent nephrotoxic agents
- Electrolyte abnormalities
- Prolonged use
- Obese patients
- Neonates/infants
- Elderly pts
Pregnancy Category:D
Breastfeeding: Poorly excreted in breastmilk. Streptomycin would not be expected to adversely affect the breastfed infants. Monitor the infant for adverse effects such as diarrhea, candidiasis (e.g., thrush, diaper rash) or symptoms of antibiotic-associated colitis.
