It is especially important to check for allergens. Avoiding the corresponding allergens after checking for allergens can reduce or attenuate the onset of allergic cough. Many people have allergies to some food components that also tend to cause allergic cough attacks and need to avoid these foods to effectively prevent and relieve the symptoms of allergic cough. Some people are allergic to airborne ingredients and may not be able to avoid contact with them, so they need to be treated with anti-allergy medications such as loratadine, paracetamol and cetirizine hydrochloride. In children, desloratadine can be used. During a cough attack, terbutaline sulfate and budesonide should be used for nebulized inhalation treatment. After checking for allergens, desensitization treatment can be done if conditions allow, which is also very helpful in preventing and treating allergic cough.
