On the other hand, studies show that Claritin takes many hours to start working.Even further, studies show that Allegra is nearly as good as Zyrtec at treating hayfever, although Zyrtec and its isomer Xyzal (levocetirizine) appear to be better medicines for the treatment of hives.It's common for people with hives (called urticaria) or hay fever (called allergic rhinitis) to wonder which over-the-counter antihistamine they should take: Claritin (loratadine), Zyrtec (cetirizine), or Allegra ( Depending on the allergic condition being treated, the age of the person, as well as other underlying issues (such as pregnancy), the best choice of antihistamine might be different.When you have been exposed to a substance you are allergic to (such as pet dander, dust mite, ragweed, or peanuts), your body produces histamine, which is a chemical messenger released by cells in the immune system to alert the rest of the immune system to a foreign invader.Dosing While you should consult your doctor about the best way to take any medication, there are widely accepted dosing recommendations for all three of these antihistamines.First and foremost, each works best when taken daily rather than intermittently.
) and Atarax (hydroxyzine) can be helpful for allergies and hives, as well, but their use is limited due to side effects such as fatigue and sedation (sleepiness).

Zyrtec, on the other hand, causes sedation in approximately one in six people who take the medication.
Juices such as orange juice or grapefruit juice can decrease the absorption of Allegra by nearly half.
The best antihistamine choice for any one person is based on the degree of symptom relief desired and the degree of side effects you are willing to tolerate.
