How LINCOCIN Works

Lincomycin inhibits bacterial protein synthesis by binding to the 23S RNA of the 50S subunit of the bacterial ribosome. This action is predominantly bacteriostatic in vitro, inhibiting the growth and multiplication of susceptible bacteria.

LINCOCIN Boxed Warning

WARNING Clostridioides difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including LINCOCIN and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile. Because lincomycin therapy has been associated with severe colitis which may end fatally, it should be reserved for serious infections where less toxic antimicrobial agents are inappr...
