Hi, I had gone through your question and understand your concerns. Nebulisation is a form of drug delivery used for direct delivery of medicines in lungs .As drug used is in very small amount and acts directly in lungs ,it has very less side effects as compared to oral medications . Some sensitive persons can have tremors with asthalin and Duolin nebulisation . Both asthalin and Duolin with or without budecort are very much safe in prescribed doses . Contrary to popular belief nebulisation does not lead to habituation . Hope this answers your question. If you have additional questions then please do not hesitate in writing to us. Take care. • DISCLAIMER: - All the information provided here is for information purpose only , it is not a substitute for the advice of a physician after physical examination , it is not intended to replace your relationship with your doctor.
