What Experts Say

Clarithromycin belongs to the macrolide class of antibiotics. It works by binding to bacterial ribosomes and blocking protein synthesis, which stops bacteria from growing and multiplying. This bacteriostatic action gives the body's immune system time to clear the remaining infection naturally.

The drug's chemical structure is more acid stable than older macrolides, allowing consistent absorption from the gut and strong penetration into lung, sinus, tonsil and skin tissue. This tissue affinity is why clinicians often choose it for respiratory tract and skin infections rather than infections limited to the bloodstream.

Clarithromycin is metabolized mainly through liver enzymes, so it can raise or lower blood levels of several other drugs metabolized the same way. Dose adjustment is often needed in people with significant liver or kidney impairment. Finishing the complete course, even after symptoms improve, is essential to prevent partially treated bacteria from developing resistance.
