Best Answer: Atarax will not cause a false positive on a urine test. Atarax (hydroxyzine HCl) is unrelated chemically to the phenothiazines, reserpine, meprobamate, or the benzodiazepines. It is classed as a piperazine antihistamine. Still, you need to inform the tester about all medications you are taking.
Uh oh! Hydroxyzine, also known as âAtaraxâ or âVistarilâ, is an antihistamine drug sometimes used in dogs to treat not only allergic reactions, but is also employed occasionally in the treatment of anxiety due to its sedative effects.ou may also notice a loss of coordination, vomiting, diarrhea, loss of appetite and increased thirst. At the recommended hydroxyzine dosage for dogs, side effects should be mild. Please note that animals may be allergic to antihistamines, so caution should be practiced when using this drug.
