Xyzal
Generic Name: levocetirizine (LEE voe se TIR a zeen)
Brand Names: Xyzal
----------------------------------------------------
What is Xyzal?
Xyzal (levocetirizine) is an antihistamine that reduces the natural chemical histamine in the body.
Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose. Xyzal works by blocking the actions of histamine.
Xyzal is used to treat symptoms of year-round (perennial) allergies in adults and children who are at least 6 months old. Xyzal is also used to treat symptoms of seasonal allergies in adults and children who are at least 2 years old.
Xyzal is also used to treat itching and swelling caused by chronic urticaria (hives) in adults and children who are at least 6 months old.
----------------------------------------------------
Important information about Xyzal
You should not use Xyzal if you are allergic to levocetirizine or cetirizine (Zyrtec). Do not take levocetirizine if you have end-stage kidney disease or if you are on dialysis. Any child under 12 with kidney disease should not take Xyzal.
Before taking Xyzal, tell your doctor if you are allergic to any drugs, or if you have kidney or liver disease, or gallbladder problems.
It is very important not to give a child more than the prescribed dose of this medication. A child's body absorbs twice as much of the same dose size of Xyzal as an adult's body. This medicine can cause side effects that may impair your thinking or reactions.
Be careful if you drive or do anything that requires you to be awake and alert.
Avoid drinking alcohol. It can increase some of the side effects of Xyzal.
Tell your doctor if you regularly 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). They can add to sleepiness caused by Xyzal. Call your doctor if your symptoms do not improve, if they get worse, or if you also have a fever.
