<s>[INST] Hi my daughter has a cold & was wheezing this morning (she is asthmatic & on preventer) i told how important it was to manage her asthma with the preventer because she has not been taking it. I went to work & got phone call from her & she was very distressed, she said that she got out of bed & collapsed and felt shaky. I phoned a neighbour & she went to her assistance. The neighbour said her heart rate was very fast. Not sure if ventolin can cause her to collapse? She also may have had to much ventolin. [/INST] Hi and thanks for the query, It would be as a second consideration to actually conclude she collapsed because of Ventolin. Getting an idea of the quantity she actually used is very important. Taken over dose, it can cause excessive tachycardia, abnormal heart rhythm and could cause her to fall. However, It's good to know the approximate amount used. While waiting, insisting on the fact she needs to use her Chat Doctor. Thanks and best regards, Luchuo, MD. </s>
