It is 4-8 times more effective than lincomycin and has a better therapeutic effect on both gram-positive and anaerobic bacteria. It can treat sepsis, pneumonia, skin soft tissue infection and osteomyelitis caused by sensitive bacteria, and can also be used for severe infections caused by anaerobic bacteria. For pelvic inflammatory disease and celiac disease caused by anaerobic bacteria, it can also play a good therapeutic role and needs to be properly applied orally under the guidance of a physician. The side effects are generally not very big, but it is likely to cause gastrointestinal reactions and easily cause pseudomembranous enteritis, and a few patients may also have allergic reactions.
