  • In patients with known hypersensitivity to macrolide antibiotic drugs.
  • Concomitant administration of clarithromycin with cisapride, pimozide, terfenadine


Clarithromycin is principally excreted by the liver and kidney. Clarithromycin may be administered without dosage adjustment to patients with hepatic impairment and normal renal function. However, in the presence of severe renal impairment with or without coexisting hepatic impairment, decreased dosage or prolonged dosing intervals may be appropriate.
Pregnancy and lactation: Clarithromycin should not be used during pregnancy and lactation, unless absolutely needed.


Allergy reaction is minor to severe,
Nausea, vomiting, anorexia, diarrhea,
Headache, dizziness, anxiety, insomnia,
Altered liver function tests.
As with other macrolides, QT prolongation, ventricular tachycardia and torsades de pointes have been rarely reported with clarithromycin.


Elevated cisapride, pimozide and terfenadine levels have been reported in patients receiving either of these drugs and clarithromycin concomitantly. This may result in QT prolongation and cardiac arrhythmia including ventricular tachycardia, ventricular fibrillation and torsades de pointes. Therefore, clarithromycin and either of these drugs are not  used concomitantly. Similar effects have been observed with concomitant administration of astemizole.
As with other macrolide antibiotics, the use of clarithromycin in patients concurrently taking drugs metabolized by the cytochrome P450 system (e.g., carbamazepine, warfarin, ergot alkaloids, triazolam, disopyramide, lovastatin, rifabutin, phenytoin and cyclosporins) may be associated with elevations in serum levels of these other drugs.
The administration of clarithromycin to patients who are receiving theophylline has been associated with an increase in serum theophylline levels. Monitoring of serum theophylline concentrations should be considered for patients receiving theophylline.
The use of clarithromycin in patients receiving warfarin may potentiate the effects of warfarin. Prothrombin time should be carefully monitored in these patients.
Clarithromycin may potentiate the effects of carbamazepine and phenytoin due to inhibition of their metabolism.
Elevated digoxin serum concentrations have been reported in patients receiving clarithromycin and digoxin concomitantly. Monitoring of serum digoxin levels should be considered.
Simultaneous oral administration of clarithromycin and zidovudine to HIV-infected adult patients may result in decreased zidovudine concentration.
