Drug interactions
Moderate drug interactions
Moderate:
chlorotrianisene lefamulin
Applies to: chlorotrianisene and lefamulin
The following interaction applies only if you are receiving the oral formulation of lefamulin (Xenleta), but not the intravenous formulation:
Lefamulin taken orally may increase the blood levels and effects of chlorotrianisene. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
lefamulin Food/Lifestyle
Applies to: lefamulin
The following interaction applies only if you are taking lefamulin (Xenleta) orally:
Food may interfere with the absorption of lefamulin, which may lead to lower blood levels of the medication and possibly reduced effectiveness. You should take lefamulin at least 1 hour before or 2 hours after a meal. It is best to avoid or limit the consumption of grapefruit and grapefruit juice during treatment with lefamulin, as it may increase blood levels of the medication and increase side effects. Talk to your doctor or pharmacist if you have any questions or concerns.

Disease interactions
4 potential interactions Applies to: 4 conditions, including Arrhythmia, Liver Disease, Noninfectious Colitis, and Renal Dysfunction.
Arrhythmia
Major:
lefamulin
Lefamulin has a major potential interaction with Arrhythmia.
The use of lefamulin should be avoided in patients with known QT prolongation, ventricular arrhythmias including torsades de pointes, and patients receiving drugs that prolong the QT interval such as antiarrhythmic agents. In patients predisposed to QT prolongation, or those receiving another drug that prolongs the QT interval, ECG monitoring is recommended during treatment.
Liver Disease
Moderate:
lefamulin
Lefamulin has a moderate potential interaction with Liver Disease.
The half-life of lefamulin is prolonged in subjects with severe hepatic impairment. Lefamulin tablets have not been studied in patients with hepatic impairment. It is not recommended to use them in patients with moderate or severe hepatic impairment. The dosage of lefamulin injection should be reduced by extending the dosing interval for patients with severe hepatic impairment. In patients with mild, moderate, or severe hepatic impairment, metabolic disturbances associated with hepatic impairment may lead to QT prolongation. Caution is advised.
Noninfectious Colitis
Major:
lefamulin
Lefamulin has a major potential interaction with Noninfectious Colitis.
Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.
Renal Dysfunction
Moderate:
lefamulin
Lefamulin has a moderate potential interaction with Renal Dysfunction.
No dosage adjustment of lefamulin is warranted in patients with renal impairment, including those on hemodialysis. However, in patients with renal failure who require dialysis, metabolic disturbances associated with renal failure may lead to QT prolongation. Monitoring is advised.
