Lincocin (Lincomycin) - Indications and Dosage



LINCOCIN Sterile Solution 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 antibiotic-associated pseudomembranous colitis, as described in the WARNING box, before selecting lincomycin the physician should consider the nature of the infection and the suitability of less toxic alternatives (eg, erythromycin).

Bacteriologic studies should be performed to determine the causative organisms and their susceptibility to lincomycin.

Indicated surgical procedures should be performed in conjunction with antibiotic therapy.

Lincomycin has been demonstrated to be effective in the treatment of staphylococcal infections resistant to other antibiotics and susceptible to lincomycin. Staphylococcal strains resistant to LINCOCIN have been recovered; culture and susceptibility studies should be done in conjunction with therapy with LINCOCIN. In the case of macrolides, partial but not complete cross resistance may occur (see Microbiology). The drug may be administered concomitantly with other antimicrobial agents when indicated.

Lincomycin is not indicated in the treatment of minor bacterial infections or viral infections.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of LINCOCIN and other antibacterial drugs, LINCOCIN should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.


If significant diarrhea occurs during therapy, this antibiotic should be discontinued. (See WARNING box.)



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.



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. Intravenous doses are given on the basis of 1 gram of lincomycin diluted in not less than 100 mL of appropriate solution (see PHYSICAL COMPATIBILITIES) and infused over a period of not less than one hour.

These doses may be repeated as often as required to the limit of the maximum recommended daily dose of 8 grams of lincomycin.

Pediatric patients over 1 month of age

10 to 20 mg/kg/day (5 to 10 mg/lb/day) depending on the severity of the infection may be infused in divided doses as described above for adults.

NOTE: Severe cardiopulmonary reactions have occurred when this drug has been given at greater than the recommended concentration and rate.


0.25 mL (75 mg) injected subconjunctivally will result in ocular fluid levels of antibiotic (lasting for at least 5 hours) with MICs sufficient for most susceptible pathogens.

Patients with diminished renal function

When therapy with LINCOCIN is required in individuals with severe impairment of renal function, an appropriate dose is 25 to 30% of that recommended for patients with normally functioning kidneys.
