When bronchitis occurs, it is usually treated with oral antibiotics and takes about 5-10 days to heal. Severe cases of bronchitis need to be treated with fluids, which can prolong the treatment time. Bronchitis caused by bacterial infections is not well treated with antiviral drugs, which can prolong the course of the disease, and requires antibiotics, such as ceftriaxone or cephradine, which are effective. Bronchitis will have symptoms of cough and phlegm, which can be treated with cough suppressing and phlegm dissolving drugs, such as Mucosolvan.
