<s>[INST] Hi I am using Formonide 400 inhaler.. I heard that once I start this i wont be able to stop . Is it correct?My uncle started with Asthalin and now he is using formonide.. For me my doctor gave me formonide for breathing difficulty coz of high allergy [/INST] hi welcome to HCMit is not correct that  once you start inhaler you wont be able to stopthe main idea of prescribing inhaled medications is - low dose medications could be used when compared to oral medication which have many side effects though the later are cheaper,and secondly the site of action of medications will be in lung itselfregarding your query your uncle might be initially having intermittent asthma later on when it got converted to persistent asthma  he might have been prescribed on formonide.regarding your case your doctor might step down your therapy from formonide based on your response to therapy and your symptomshope you got your answerwith warm regardsDr NSK </s>
