If significant diarrhea occurs during treatment, lincomycin should be discontinued.

Clostridium difficile associated diarrhea (CDAD) has been reported with almost all antibiotics and may potentially be life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea following lincomycin therapy. Lincomycin therapy has been associated with severe colitis which may end fatally; therefore, it should be reserved for serious infections where less toxic antimicrobial agents are inappropriate. It should not be used in patients with nonbacterial infections such as most upper respiratory tract infections. Diarrhea, colitis, and Clostridium difficile pseudomembranous colitis have been observed to begin up to several weeks following discontinuation of lincomycin. Mild cases generally improve with discontinuation of the drug, while severe cases may require supportive therapy and treatment with an antimicrobial agent effective against C difficile. Hypertoxin producing strains of C difficile cause increased morbidity and mortality; these infections can be resistant to antimicrobial treatment and may necessitate colectomy.

Severely ill elderly patients may tolerate diarrhea less well. When lincomycin is indicated in these patients, they should be carefully monitored for change in bowel frequency.

Lincomycin should be prescribed cautiously for patients with a history of gastrointestinal disease, particularly colitis, and in atopic individuals. It should also be used with caution in patients with a history of asthma or significant allergies.

Lincomycin should not be used in the treatment of meningitis because it does not diffuse adequately into the cerebrospinal fluid.

Use with caution in patients with severe renal and/or hepatic dysfunction. The lincomycin serum concentration should be monitored during high-dose treatment.

The injectable formulation contains benzyl alcohol which may cause fatal gasping syndrome in premature infants.

Lincomycin should not be administered undiluted as an intravenous bolus injection. It should be infused over at least 60 minutes; the infusion rate should not exceed 1 g per hour. The concentration should not exceed 10 mg/mL. Severe cardiopulmonary events have occurred when the recommended concentration and rate have been exceeded.

During prolonged therapy, periodic liver and kidney function tests and blood counts should be performed.

To reduce the risk of development of drug resistant organisms, antibiotics should only be used to treat or prevent proven or suspected infections caused by bacteria. Culture and susceptibility information should be considered when selecting treatment or, if no data are available, local epidemiology and susceptibility patterns may be considered when selecting empiric therapy. Patients should be advised to avoid missing doses and to complete the entire course of therapy.


Hemodialysis and peritoneal dialysis are not effective in removing lincomycin from the serum.
