<s>[INST] Hi My 15 year old daughter is taking seretide twice a day to clear inflammation in lungs etc.  She has not had asthma, to my knowledge, previously.  She is an elite athlete and is also iron deficient.  My question is could she have exercise induced asthma and is it safe to give her fefol as an iron supplement? Thank you [/INST] If she is taking seretide regularly that maens she has asthma which is well controlled with seretide. Yes there is a term called exercise induced asthma. If she she still has symtoms during asthma despite taking seretide, she may take 2 puffs of levolin 10 min prior to starting exercise. </s>
