Hello, Thank you for asking at HCM. I went through your history and would like to make suggestions for her as follows: 1. As she has cough along with headache, I would first like to know about her nose symptoms, whether she has running nose, nose congestion, mouth breathing, sneezing, etc. If any of above symptoms are present, I usually prescribe my such patients levocetirizine + montelukast for 7-14 days repending upon response. Regular steam inhalation will also help. 2. Whooping cough with pneumonia is unusual presentation. So I would not first suspect whooping cough in her, unless she has been in contact with a patient with whooping cough. 3. Viral infections can sometimes be prolonged, may be up to 4-6 weeks. Also, cough takes long time to respond to medications. So I would personally think of viral infection first. 4. Regular warm saline gargles will help soothing throat and hence may help early recovery. 5. Please avoid exposure to dusts, smokes and air pollution as much as possible. 6. Please have a nutritious diet with adequate warm fluids during days maintain hydration which may help early recovery. Hope above suggestions will be helpful to your daughter. Should you have any further query, please feel free to ask at HCM. Wish your daughter a quick recovery and the best of the health ahead. Thank you & Regards.
