Biaxin XL
(clarithromycin)
How does Biaxin XL work? What will it do for me?
Clarithromycin belongs to the class of medications called macrolide antibiotics. It is used to treat infections caused by certain bacteria. It works by killing or stopping the growth of bacteria that can cause certain infections. Clarithromycin may be prescribed for people with bacterial throat infections, sinus infections, ear infections, lung infections such as chronic bronchitis exacerbation, pneumonia, and skin infections such as impetigo and cellulitis.
Clarithromycin may also be used to prevent and treat certain infections associated with human immunodeficiency virus (HIV) infection. Clarithromycin can be used in combination with other medications to kill H. Pylori, a bacteria known to cause ulcers in the digestive tract.
