12.1 Mechanism of Action Clarithromycin is a macrolide antimicrobial drug [see Microbiology ( 12.4 )] .

Clarithromycin is a macrolide antimicrobial indicated for mild to moderate infections caused by designated, susceptible bacteria in the following: Acute Bacterial Exacerbation of Chronic Bronchitis in Adults ( 1.1 ) Acute Maxillary Sinusitis ( 1.2 ) Community-Acquired Pneumonia ( 1.3 ) Pharyngitis/Tonsillitis ( 1.4 ) Uncomplicated Skin and Skin Structure Infections ( 1.5 ) Acute Otitis Media in Pediatric Patients ( 1.6 ) Treatment and Prophylaxis of Disseminated Mycobacterial Infections ( 1.7 ) Helicobacter pylori Infection and Duodenal Ulcer Disease in Adults ( 1.8 ) Limitations of Use To reduce the development of drug-resistant bacteria and maintain the effectiveness of clarithromycin tablets and other antibacterial drugs, clarithromycin tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. ( 1.9 ) 1.1 Acute Bacterial Exacerbation of Chronic Bronchitis Clarithromycin tablets are indicated in adults for the treatment of mild to moderate infections caused by susceptible isolates due to Haemophilus influenzae , Haemophilus parainfluenzae , Moraxella catarrhalis , or Streptococcus pneumoniae [see ( 1.9 )] . 1.2 Acute Maxillary Sinusitis Clarithromycin tablets are indicated for the treatment of mild to moderate infections caused by susceptible isolates due to Haemophilus influenzae , Moraxella catarrhalis , or Streptococcus pneumoniae [see ( 1.9 )] . 1.3 Community-Acquired Pneumonia Clarithromycin tablets are indicated [see ( 1.9 )] for the treatment of mild to moderate infections caused by susceptible isolates due to: Haemophilus influenzae (in adults) Mycoplasma pneumoniae, Streptococcus pneumoniae, Chlamydophila pneumoniae (in adults and pediatric patients) 1.4 Pharyngitis/Tonsillitis Clarithromycin tablets are indicated for the treatment of mild to moderate infections caused by susceptible isolates due to Streptococcus pyogenes as an alternative in individuals who cannot use first line therapy. 1.5 Uncomplicated Skin and Skin Structure Infections Clarithromycin tablets are indicated for the treatment of mild to moderate infections caused by susceptible isolates due to Staphylococcus aureus , or S treptococcus pyogenes . 1.6 Acute Otitis Media Clarithromycin tablets are indicated in pediatric patients for the treatment of mild to moderate infections caused by susceptible isolates due to Haemophilus influenzae , Moraxella catarrhalis , or Streptococcus pneumoniae [see Clinical Studies ( 14....

For H. influenzae and H. parainfluenzae , use 500 mg. † For H parainfluenzae , the duration of therapy is 7 days. ǂ For H. influenzae , the duration of therapy is 7 days. § Clarithromycin therapy should continue if clinical response is observed. Clarithromycin can be discontinued when the patient is considered at low risk of disseminated infection. 2.3 Combination Dosing Regimens for H. pylori Infection Triple therapy: clarithromycin/lansoprazole/amoxicillin The recommended adult dosage is 500 mg clarithromycin tablets, 30 mg lansoprazole, and 1 gram amoxicillin, all given every 12 hours for 10 or 14 days [see ( 1.8 ) and Clinical Studies ( 14.3 )] ....

The following serious are described below and elsewhere in the labeling: Acute Hypersensitivity Reactions [see ( 5.1 )] QT Prolongation [see ( 5.2 )] Hepatotoxicity [see ( 5.3 )] Serious Due to Concomitant Use with Other Drugs [see ( 5.4 )] Clostridium difficile Associated Diarrhea [see ( 5.6 )] Exacerbation of Myasthenia Gravis [see ( 5.8 )] Most frequent for both adult and pediatric populations in clinical trials: abdominal pain, diarrhea, nausea, vomiting, dysgeusia ( 6.1 ) To report SUSPECTED , contact Sandoz Inc. at 1-800-525-8747 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Based on pooled data across all indications, the most frequent for both adult and pediatric populations observed in clinical trials are abdominal pain, diarrhea, nausea, vomiting and dysgeusia. Also reported were dyspepsia, liver function test abnormal, anaphylactic reaction, candidiasis, headache, insomnia, and rash. The subsequent subsections list the most common for prophylaxis and treatment of mycobacterial infections and duodenal ulcer associated with H. pylori infection. In general, these profiles are consistent with the pooled data described above. Prophylaxis of Mycobacterial Infections In AIDS patients treated with clarithromycin over long periods of time for prophylaxis against M. avium , it was often difficult to distinguish possibly associated with clarithromycin administration from underlying HIV disease or intercurrent illness. Median duration of treatment was 10.6 months for the clarithromycin group and 8.2 months for the placebo group. Table 4.

Hypersensitivity to clarithromycin or any macrolide drug ( 4.1 ) Cisapride and pimozide ( 4.2 ) History of cholestatic jaundice/hepatic dysfunction with use of clarithromycin ( 4.3 ) Colchicine in renal or hepatic impairment ( 4.4 ) Lomitapide, lovastatin, and simvastatin ( 4.5 ) Ergot alkaloids (ergotamine or dihydroergotamine) ( 4.6 ) Lurasidone ( 4.7 ) 4.1 Hypersensitivity Clarithromycin tablets are contraindicated in patients with a known hypersensitivity to clarithromycin, erythromycin, or any of the macrolide antibacterial drugs [see ( 5.1 )] . 4.2 Cisapride and Pimozide Concomitant administration of clarithromycin tablets with cisapride and pimozide is contraindicated [see ( 7 )] . There have been postmarketing reports of when clarithromycin is co‑administered with cisapride or pimozide, resulting in cardiac arrhythmias (QT prolongation, ventricular tachycardia, ventricular fibrillation, and torsades de pointes ) most likely due to inhibition of metabolism of these drugs by clarithromycin tablets. Fatalities have been reported. 4.3 Cholestatic Jaundice/Hepatic Dysfunction Clarithromycin tablets are contraindicated in patients with a history of cholestatic jaundice or hepatic dysfunction associated with prior use of clarithromycin. 4.4 Colchicine Concomitant administration of clarithromycin tablets and colchicine is contraindicated in patients with renal or hepatic impairment. 4.5 Lomitapide, Lovastatin, and Simvastatin Concomitant administration of clarithromycin tablets with lomitapide is contraindicated due to potential for markedly increased transaminases [see ( 5.4 ) and ( 7 )]. Concomitant administration of clarithromycin tablets with HMG-CoA reductase inhibitors (statins) that are extensively metabolized by CYP3A4 (lovastatin or simvastatin) is contraindicated, due to the increased risk of myopathy, including rhabdomyolysis [see ( 5.4 ) and ( 7 )]. 4.6 Ergot Alkaloids Concomitant administration of clarithromycin and ergotamine or dihydroergotamine is contraindicated [see ( 7 )] . 4.7 Lurasidone Concomitant administration of clarithromycin and lurasidone is contraindicated since it may result in an increase in lurasidone exposure and the potential for serious [see ( 7 ) ]. 4.8 for Co-administered Drugs For information about of other drugs indicated in combination with clarithromycin tablets, refer to their full prescribing information ( section).
