Clarithromycin is a macrolide antibiotic used for the treatment of a wide variety of bacterial infections such as acute otitis, pharyngitis, tonsillitis, respiratory tract infections, uncomplicated skin infections, and helicobacter pylori infection.

For most infections, you should feel better within a few days. For skin problems such as cellulitis, you may have to take the medicine for about 7 days before you see any improvement.

The overuse of antibiotics makes resistant bacteria more common. The more we use antibiotics, the more chances bacteria have to become resistant to them hence making antibiotics less effective.
