The patient does not need to apply antibiotics for rhinitis, except in special cases, with the following analysis: 1. Acute rhinitis, also known as the common cold, is caused by viral infection. 2. Allergic rhinitis does not require antibiotics because it is mainly caused by a metamorphic reaction and is not related to bacterial infection, so there is no need for antibiotics. 3. Chronic rhinitis is mostly caused by recurrent episodes of acute rhinitis, mainly manifesting as nasal disinflation, runny nose, etc. Most of them are not accompanied by bacterial infection and do not require antibiotic treatment. 4. Dry rhinitis and atrophic rhinitis also do not have bacterial infection in the nasal cavity, most of them are caused by dryness, erosion and ulceration of the nasal mucosa, and other symptomatic treatments can be carried out without the need for oral antibiotics.
