What Experts Say

Clarithromycin inhibits bacterial protein synthesis by binding the fifty S ribosomal subunit, giving it reliable activity against the organisms that commonly cause community acquired respiratory infections. Physicians often choose it when a patient reports penicillin allergy, since cross reactivity with macrolides is minimal.

Respiratory infections remain one of the most frequent reasons for antibiotic prescribing in outpatient clinics across Pakistan, and clarithromycin is a standard second line choice after amoxicillin for suspected atypical organisms. Physicians stress completing the full course to limit the growing problem of antibiotic resistance.

Clarithromycin can prolong the QT interval and interacts with several common drug classes through liver enzyme inhibition, so physicians review a patient's full medication list before prescribing it, particularly in older adults and those on statins or heart rhythm medicines.
