Doxycycline (100 mg orally twice daily or 200 mg orally daily) is a reasonable alternative for first-line therapy and can be used in patients with penicillin allergy . A respiratory fluoroquinolone (levofloxacin 500 mg orally or moxifloxacin 400 mg orally once daily) is another option for penicillin-allergic patients. Macrolides (clarithromycin or azithromycin), trimethoprim-sulfamethoxazole, and second- or third-generation cephalosporins are not recommended for empiric therapy because of high rates of resistance of S. pneumoniae (and of H. influenzae for trimethoprim-sulfamethoxazole).
Ciprofloxin is not respiratory fluoroquinolone as you know. It is good for urinary tract infection.
