What Experts Say

Clarithromycin is a macrolide antibiotic that binds to the 50S ribosomal subunit of susceptible bacteria, blocking protein synthesis needed for their growth. This action is bacteriostatic at usual doses and can become bactericidal against certain organisms at higher tissue concentrations, particularly in the respiratory tract.

Respiratory and throat infections are common across Pakistan due to seasonal changes, indoor air pollution, and smoking. Clarithromycin offers reliable coverage against typical and atypical organisms, making it a preferred option for patients with penicillin allergy or infections not responding to first line antibiotics.

Doctors check for heart rhythm concerns and review other medicines before prescribing clarithromycin, since it can prolong the QT interval and interacts with several common drugs including statins and blood thinners. Liver function is monitored during longer courses, and the drug is generally avoided in pregnancy unless necessary.
