Its use in food allergies is unclear. Allergies are common. In the developed world, about 20% of people are affected by allergic rhinitis, about 6% of people have at least one food allergy, and about 20% have atopic dermatitis at some point in time. Depending on the country about 1â18% of people have asthma.
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.
It should be noted that there are a few different forms of hydroxyzine (tablets, capsules, syrup, oral suspension, and injections), and not all forms are approved for all uses. This medicine is particularly useful when combined with opioid pain relievers, such as morphine. Not only does hydroxyzine help the opioid to work better (allowing a lower opioid dosage to be used), but it helps relieve the itching that opioids can cause.
