Ventolin

hi there, could you help me with this, if you have experienced with Ventolin

My sister felt so useless and depressed, so she took her ventolin inhaler and 
abuse it. i think she is going to suicide, because she has depressed problems. 
she told me that she felt her heart beat so fast and she cant breathe well. 
when i coax and persuade her how she is important to me, she became better, then 
she took her bath and then she said everything felt much better. is this real or 
she just want to make me feel better? is there any long term effects on her? it 
is so hard to bring her to see doctor.. 


i want to know, if she completely abuse her ventolin again, can she really die? 
and how to treat it. i know i shouldnt ask this questions... but i am so 
curious.

i have been searching the net and found that it can be cure by fluids through an 
intravenous line (IV),
medications (such as beta blockers) that can reverse the effects of Ventolin but 
is it true that it can really safe her

and how long does it takes to recover usually?  please help me. thank you very 
very much~
