Answer: Ativan (Lorazepam) is a benzodiazepine ...So may show positive for prescription medications (some 5 panel tests) and also positive for benzo for 12 panel test and some expanded drug tests ( includes 5 basic drugs plus combination of 3, 4,5, etc.. additional drugs like Benzodiazepines, Hydrocodone , Methadon, etc..)
Answer: No, not unless they are checking for that specific drug. I assume you are not using it recreationally, but if you are, you can say that you have a prescription for it. You and your doctor can not be forced to share medical information with anyone unless given a court order.
Answer: It does not show up on a typical drug screen because it is NOT an opiate or any other class of controlled substance. Meclizine is an antihistamine used to treat or prevent nausea, vomiting, and dizziness caused by motion sickness.
Answer: Maybe, but even if Atripla showed up on a drug test, as long asthere is a valid medical reason to take it (HIV infection), thenthere should be no problem. This is not a drug used forrecreational purposes.
Answer: Depends on what drug you took, for example benzodiazepines (Ativan, Klonopin, Xanax, Valium ect..) WILL show up on a basic drug screen. I recommend asking what they are testing for so then you know in advance, the basics include THC, Benzodiazepines, Opiates (percocets, heroin, morphine) and cocaine.
