Answer: Xanax (alprazolam) and other benzodiazepines can be detected with a urinalysis however they are not always tested for. The most basic test is a 5 panel test able to detect PCP, THC (marijuana), cocaine, amphetamines (including meth and ecstasy), and opiates (morphine, codeine, and heroin only). It is common for extra drugs tests to be added to the basic five panel. Benzodiazepines, oxycodone, hydrocodone, and barbiturates are most commonly added to the 5 panel. Except with very sophisticated and expensive tests individual benzodiazepines are not tested for so people only show positive for benzodiazepines.
Answer: It mostly depends on the drug test you will be taking and how much is in your system. Less than a week for mouth swabs. But there are accounts of people failing 2, 3, and even 4 weeks later for blood and urine tests.
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.
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: Most drug screens are intentionally not very specific, they will pick up parts of the molecular structure of drugs that are present in a whole variety of similar drugs.
Xanax is a sedative of the benzodiazepine class, meaning that the drug molecule has a certain two-ringed chemical structure with 2 nitrogen atoms in it. The tests pick up this common structural element in many sedatives (the same element is also responsible for the similar action of the drugs). Examples are valium, seresta, restoril etc.
The test will usually only say that one of that list of drugs is present.
