There are two reasons for coughing at the smell of smoke: allergic patients who have an allergic cough after smelling smoke, and patients with asthma who are irritated by the smell of smoke, causing an asthma attack. If you have an allergic cough, you need to get rid of the smoke and take anti-allergy medications such as Desloratadine, Loratadine, Paracetamol or Cetirizine Hydrochloride, all of which are effective. In the case of coughing in infants and children who smell smoke, dexloratadine is recommended to relieve the symptoms. If an asthma attack occurs, nebulized inhalation medication is needed for treatment. In the case of adults or children over 10 years old, nebulized inhalation of Cymbalta is needed. For infants and children under 10 years of age, nebulized inhalation of budesonide and terbutaline are recommended to relieve cough symptoms.
