Vistaril is a brand-name for the compound hydroxyzine. It is an antihistamine, and though it may cause sedation (similar to Benadryl, another antihistamine) it is not considered to be a "psychoactive" drug nor is it done on a drug triage screen.
Answer: No. Pregnancy tests measure the amount of a specific hormone (HCG) that is produced by the embryo once fertilization takes place. Drug tests do not test for this hormone.

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: Depends on what drug you took, for example benzodiazepines (Ativan, Klonopin, Xanax, Valium ect..) WILL show up on a basic drug screen.

Answer: Unless it is being tested for, no; Cipro is not a drug that any sane person would try to use for getting high, and it is not illegal (jsut extremely bad-tasting and lacking in any stimulative effects whatsoever).
