Hi, thanks for using healthcare magic Macox plus is used in the treatment of tuberculosis. It is a combination of two medications isoniazid and rifampicin. If her doctor has prescribed this then he or she believes that her coughing may be related to tuberculosis and it would be important to continue the course of treatment as prescribed. If you have any questions about the diagnosis or treatment then it would be best to speak to your doctor about your concerns. In terms of asthma- this would normally present with a dry cough which may be worse at night, shortness of breath, chest pain or tightness and wheezing. The symptoms can be brought on or made worse by : an infection of the respiratory tract like the common cold, exercise, cold environment, emotions, allergies and reflux can also worsen asthma symptoms. Asthma is a serious condition- treatment involves avoiding the triggers and the use of inhalors . Inhalors are classified as reliever inhalors ( to be used when the symptoms occur) and preventer inhalors ( to be used to prevent asthma symptoms). If you suspect she is an asthmatic and this is confirmed by her doctor, she should be on inhalors. I hope this helps
