My girlfriend took 3 ambien (zolpidem) and 3 lorazipam. her normal dose is 1 pill of each. how concerned should i be? what should i look out for?

Ambien/Ativan OD?: Not sure what the dosages are, but watch for confusion, dizziness, and in any case, contact her doctor for advise.

Take her to ER: This can be very dangerous,

Be concerned: Would take to local emergency room if she cannot be easily aroused, or has trouble breathing. Definitely contact her physicians regarding this. Maybe just a modest overdose now, but could be a bigger problem in future. Get this handled.
