Injection route (Solution)

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.Because lincomycin therapy has been associated with severe colitis which may end fatally, it should be reserved for serious infections where less toxic antimicrobials agents are inappropriate. It should not be used in patients with nonbacterial infections such as most upper respiratory tract infections.C difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C difficile, and surgical evaluation should be instituted as clinically indicated.

For Healthcare Professionals

Applies to lincomycin: compounding powder, injectable solution, oral capsule.


The onset of pseudomembranous colitis symptoms has been reported during and after antibacterial therapy.

Esophagitis was reported with oral preparations.[Ref]

Frequency not reported: Glossitis, stomatitis, nausea, vomiting, abdominal distress, persistent diarrhea, enterocolitis, antibacterial-associated diarrhea and colitis, pruritus ani, pseudomembranous colitis, Clostridium difficile associated diarrhea, esophagitis[Ref]


Frequency not reported: Hypersensitivity reactions (such as angioneurotic edema, serum sickness, anaphylaxis); face, ears, and neck swelling[Ref]

Some hypersensitivity reactions occurred in penicillin-sensitive patients.

A 19-year-old male patient, who had received 2 previous IM injections of lincomycin at the age of 17 years and 1 IM injection 2 weeks prior, reported that a few minutes after his fourth IM injection he noticed a tingling sensation around his face and mouth. The patient's symptoms progressed to bright red to blue-violet skin discoloration, injection of the bulbar conjunctivae, and swelling of his face, neck, and ears. The patient recovered without incident after receiving adrenaline and betamethasone IM followed by oral prednisone with an antihistamine.[Ref]


Rare (less than 0.1%): Exfoliative and vesiculobullous dermatitis

Frequency not reported: Skin rashes, urticaria, pruritus, erythema multiforme (some resembling Stevens-Johnson syndrome)[Ref]


Rare (less than 0.1%): Aplastic anemia, pancytopenia

Frequency not reported: Neutropenia, leukopenia, agranulocytosis, thrombocytopenia, thrombocytopenic purpura[Ref]


Cases of hypotension after parenteral administration have been reported, especially after too rapid IV administration. Rare cases of cardiopulmonary arrest have been reported after this drug was administered IV too rapidly. In these cases, the affected patients subsequently tolerated slow infusions. A study that looked at multiple large dose administration of this drug found that when the doses were appropriately diluted and administered more slowly, cardiovascular changes did not occur.[Ref]

Rare (less than 0.1%): Cardiopulmonary arrest

Frequency not reported: Hypotension[Ref]


Frequency not reported: Jaundice, abnormal liver function tests (especially elevated serum transaminase)[Ref]


Rare (less than 0.1%): Renal dysfunction, azotemia, oliguria[Ref]


Rare (less than 0.1%): Proteinuria

Frequency not reported: Vaginitis[Ref]

Nervous system

Frequency not reported: Tinnitus, vertigo, neuromuscular blockade, metallic taste in mouth[Ref]


Frequency not reported:

-IM: Pain following injection, local irritation, pain induration, sterile abscess formation

-IV: Thrombophlebitis[Ref]


Frequency not reported: Bulbar conjunctival injection
