Hello. Thank you for asking at HCM. If despite of using levolin and budecort inhalers he is having cough, it means his asthma is not under control. Before straightway jumping to increase medications, I would like to make sure that your brother is using the inhalers with right technique. A proper co-ordination between hand & breathing is very important for right use of inhalers. If he is not using a spacer with inhaler, I would suggest to use it. I put emphasis on correct technique and device so much, because without it, drug does not reach to the lung in correct amount. However, if the technique and device are correct, I would suggest to add tablet montelukast as a controller medication. I would suggest you to consult an Allergist-Immunologist in Jaipur, who may suggest him allergy testing after detailed history. Based on results of allergy tests, he may suggest specific allergen immunotherapy which works on immune system to modify the allergy response. Hope this will help you. Wish your brother the best of the health. Regards.
