Streptomycin is used to treat tuberculosis (particularly in combination therapy for drug-resistant cases), plague (Yersinia pestis infection), tularemia (Francisella tularensis), and certain other serious gram-negative bacterial infections. It may also be used in the treatment of bacterial endocarditis caused by susceptible organisms.

Streptomycin is an aminoglycoside antibiotic that works by binding to the bacterial 30S ribosomal subunit, thereby inhibiting protein synthesis. This leads to misreading of the genetic code and ultimately bacterial cell death. It is bactericidal, meaning it actively kills susceptible bacteria rather than simply stopping their growth.

Streptomycin is administered by intramuscular or intravenous injection and is not absorbed orally. It carries significant risks of nephrotoxicity (kidney damage) and ototoxicity (hearing loss and vestibular damage), which require regular monitoring of drug levels, kidney function, and hearing. It should be used with caution in patients with pre-existing kidney disease, hearing disorders, or myasthenia gravis. Pregnancy is a contraindication due to potential harm to the fetus.
