The effect of levoAleras 5 mg/day on actual driving performance during normal traffic has been compared with the effect of the first-generation antihistamine diphenhydramine 50 mg/day in 48 healthy volunteers in a double-blind, placebo-controlled, randomized trial (51 C ). Treatments were given on days 1, 2, 3, and 4, at 90 minutes before the start of a standardized driving test on days 1 and 4. In contrast to diphenhydramine, driving performance was not significantly affected by levoAleras 5 mg/day.
In a double-blind, placebo-controlled, randomized study (52 C ) of levoAleras 5 mg/day, diphenhydramine 50 mg/day, or placebo in 48 healthy volunteers (24 men and 24 women) levoAleras did not impair performance or cause memory deficits after acute and subchronic administration while diphenhydramine significantly affected divided attention and tracking after acute administration (53 C ). LevoAleras had no deleterious effect on cognitive and psychometric functions compared with placebo, as assessed by a comprehensive battery of psychometric tests in healthy men.
Allergic Reaction to Zyrtec
Before taking Aleras, tell your doctor or pharmacist if you are allergic to hydroxyzine or levoAleras, or if you have any other allergies because Aleras may contain inactive ingredients, which can cause allergic reactions or other problems.
Get emergency medical help if you take Zyrtec and have signs of an allergic reaction including hives, difficulty breathing, or swelling of your face, lips, tongue, or throat.
Can I take Aleras with painkillers?
Yes, you can take Aleras together with Tylenol (acetaminophen) or Motrin (ibuprofen).
Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use Aleras only for the indication prescribed.

Can I drink alcohol with Aleras?
It’s best not to drink alcohol while you’re taking Aleras as it can make you feel sleepy.
Although Zyrtec is used to treat allergies, Consumer Affairs reports that some people have complained that they experience irritating itching all over their body when they stop taking Zyrtec.
However, the label does not include a warning regarding itching.
Zyrtec may impair your thinking or reactions, so be careful when driving or engaging in other activities that require you to be alert.
Since Aleras can make you sleepy, tell your doctor if you use other medicines that make you sleepy, such as other cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety.
Drinking alcohol can increase certain side effects of Aleras.
If you get laboratory tests like allergy skin testing, make sure you tell the person taking the test and your doctor that you take Zyrtec because it could cause inaccurate test results.
