<s>[INST] Have recently been put on symbicort . I have noticed heart palpitations. Also a lot of throat conjestion . That seems to be where the asthma lies, not so much tightness in the chest. I am also more tired a d carry weakness in my legs. I use to like walking a lot but legs tire after a block of walking. I do use ventolin and have had advair in past. What is the answer to better breathing without a lot is use of drugs with so many side effects? [/INST] If you are having very bad asthmatic attacks you need to take inhalation steroids with bronchodilators with risk benefit ratio. But if the asthma is not so bad, then these medicines as and when needed can be used. If you are on this treatment for longer duration of time then you should take calcium supplement with it D3 also. You should do regular yoga, Panama, breathing exercises, spirometry and avoid allergens and quit addiction if any you have. </s>
