Used primarily as an antibiotic in veterinary medicine and human healthcare, this compound is effective against Gram-positive bacteria and some anaerobic organisms. It is commonly prescribed for infections of the respiratory tract, skin, and soft tissues, especially in patients allergic to penicillin. In veterinary practice, it treats bacterial infections in livestock and companion animals, often in combination with other drugs to enhance efficacy. It also finds use in selective media for microbiological testing and as a feed additive to promote growth in some farm animals.
