The recovery time of allergic bronchitis varies from person to person and is related to the patient’s own physical condition and the severity of the disease. Allergic bronchitis is an airway metamorphosis caused by allergen stimulation, which occurs in old and weak people and mainly manifests as cough and sputum. Patients can be treated with anti-allergy drugs, such as loratadine tablets, paracetamol, etc. Patients with combined cough and asthma symptoms can be treated with nebulized inhalation and combined treatment with antiviral oral solution and cephalosporin tablets. If the patient is in good health and has a high immune system, significant relief of symptoms will usually occur in about 1 week. If the patient has a poor immune function, it may take 2-4 weeks to heal. Patients with allergic bronchitis should pay attention to adequate rest while applying medication, ensure sufficient sleep, avoid excessive exertion, drink more water to ensure airway moistening, and eat more fruits to supplement vitamin C to strengthen the body.
