Asthma is usually triggered by exposure to allergens resulting in episodes of cough breathlessness etc. You will need to identify what is triggering the attack of asthama. It may be allergens like pollens, dust, mite etc, Some times chemicals like perfumes, mosquito repellents etc. Adequate treatment may not be as effective if exposure to allergens is continues. You may consult immunologist who will do various test to identify possible allergens. Also visit pediatric pulmonologist for Lung Function Tests and ask him to add bronchodilator Acebrophyllin along with long acting inhaled bronchodilators etc. For any further query you may cosult me at Healthcare Magic.
