When bronchitis occurs, it is important to identify the type of bronchitis infection and then decide what medication to use for anti-inflammatory treatment. Amoxicillin belongs to the penicillin class of antibiotics and is effective for bronchitis caused by bacterial infections. However, if the bronchitis is serious, the effect of oral amoxicillin is not enough. If you want to use penicillin antibiotics, it is better to treat with intravenous penicillin drip for better effect. If a viral infection causes bronchitis, the use of amoxicillin is even more ineffective and requires the use of antiviral drugs for intravenous drip treatment. For example, you can take intravenous ribavirin or oral Tamiflu for treatment, which is more effective, not amoxicillin. At this time, if the cough and phlegm are more serious, you must use cough expectorant drugs for treatment, such as oral administration of Ambroxol Hydrochloride, Ambrotero Oral Solution or Lung Power Cough Combination.
