Lincomycin

LINCOCIN is indicated in the treatment of serious infections due to susceptible strains of streptococci, pneumococci, and staphylococci. Its use should be reserved for penicillin-allergic patients or other patients for whom, in the judgment of the physician, a penicillin is inappropriate. Because of the risk of CDAD, as described in the BOXED WARNING, before selecting lincomycin the physician should consider the nature of the infection and the suitability of other alternatives. Indicated surgical procedures should be performed in conjunction with antibacterial therapy. LINCOCIN may be administered concomitantly with other antimicrobial agents when indicated. LINCOCIN is not indicated in the treatment of minor bacterial infections or viral infections.

Lincomycin inhibits bacterial protein synthesis by binding to the 23S RNA of the 50S subunit of the bacterial ribosome. Lincomycin is predominantly bacteriostatic in vitro.

If significant diarrhea occurs during therapy, LINCOCIN should be discontinued. INTRAMUSCULAR Adults Serious infections —600 mg (2 mL) intramuscularly every 24 hours. More severe infections —600 mg (2 mL) intramuscularly every 12 hours or more often. Pediatric patients over 1 month of age Serious infections —one intramuscular injection of 10 mg/kg (5 mg/lb) every 24 hours. More severe infections —one intramuscular injection of 10 mg/kg (5 mg/lb) every 12 hours or more often. INTRAVENOUS Adults The intravenous dose will be determined by the severity of the infection. For serious infections doses of 600 mg of lincomycin (2 mL of LINCOCIN) to 1 gram are given every 8 to 12 hours. For more severe infections these doses may have to be increased. In life-threatening situations daily intravenous doses of as much as 8 grams have been given.

LINCOCIN is contraindicated in patients previously found to be hypersensitive to lincomycin or clindamycin.

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. See BOXED WARNING. Clostridioides difficile associated diarrhea Clostridioides difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Lincomycin, 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. C. difficile produces toxins A and B which contribute to the development of CDAD.

The following adverse reactions have been reported with the use of lincomycin. Gastrointestinal disorders Diarrhea, nausea, vomiting, glossitis, stomatitis, abdominal pain, abdominal discomfort Event has been reported with intravenous injection., anal pruritus Skin and subcutaneous tissue disorders Toxic epidermal necrolysis, Stevens-Johnson syndrome, acute generalized exanthematous pustulosis, dermatitis bullous, dermatitis exfoliative, erythema multiforme, rash, urticaria, pruritus Infections and infestations Vaginal infection, pseudomembranous colitis, Clostridioides difficile colitis Blood and lymphatic system disorders Pancytopenia, agranulocytosis, aplastic anemia, leukopenia, neutropenia, thrombocytopenic purpura Immune system disorders Anaphylactic reaction, angioedema, serum sickness Hepatobiliary disorders Jaundice, liver function test abnormal, transaminases increased Renal…

Lincomycin has been shown to have neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents, therefore, it should be used with caution in patients receiving such agents.

Store at controlled room temperature 20° to 25°C (68° to 77°F).
