Personal preference: Both are effective for hay fever and many people find them to be similar in effectiveness. However, some prefer one over the other.

A 25-year-old member asked:

For how long does Claritin (loratadine) stay in your system?

One day: Claritin (loratadine) 10 mg pill is dosed once daily. That's because it's effect will last about 24 hours, after that it's antihistamine effect wanes. However, Claritin is metabolized by the liver into another active compound called desloratadine, so the antihistamine effect can last a while. This is why most allergists have patients stop their Claritin a number of days before skin testing them.

Within 1-2 hrs: Claritin (loratadine) is well-absorbed from the gastrointestinal tract and its effect is often felt within 1-2 hours. Claritin is metabolized in the liver into Desloratadine (the main ingredient in clarinex) which can stay in your system for many hours, allowing these antihistamines to be dosed once daily.

Please see below.: Sometimes you can get sensitized to an allergen (including, unfortunately, cat dander) over time. If avoidance of an allergen isn't an option, the next step is to see your doctor about additional medications and possibly allergy shots.

How long should it take for my Claritin (loratadine) to work?

1-2 hours: Most medications take one to two hours to be absorbed into the blood stream. Some, such as steroids, need to be taken for several days to build up to their full effect, but this is not the case with antihistamines.
Dr. Michael P Vaughn
Allergy and Immunology 34 years experience
typically, only persons with mild allergies can take an anti-histamine such as claritin with complete control of nasal symptoms, head to head studies favor nasal steroids for control of symptoms.

Yes: Two tablets of Claritin (loratadine) most likely will cause no significant problems. However large doses of antihistamines can cause significant cardiac arrythmias.
