Klacid Uno is indicated for use in adults and children over 12 years of age in the treatment of infections caused by microorganisms sensitive to clarithromycin. These infections include:
- upper respiratory tract infections (e.g., streptococcal pharyngitis, sinusitis)
- lower respiratory tract infections (e.g., bronchitis, pneumonia)
