A souvenir from a bright PhD student who had bought this off the counter at a pharmacy in a neighbouring country.
When I did pharmacology in medical school decades ago, we were taught that this antibiotic was not commonly used because side effects (like antibiotic-associated diarrhea) were frequent. One would be hard pressed to find this antibiotic in Singapore today. A derived (and safer) compound – clindamycin – is regularly prescribed in Singapore for skin/soft tissue infections particularly in those allergic to penicillin.
Lincomycin is now commonly used in food animals, both for the treatment of infections as well as growth promotion.
