What are the different versions of Claritin?
Claritin is available in several formulations, including tablets, liquid gels, and chewables. It is also marketed as Claritin-D, which combines loratadine with pseudoephedrine, a decongestant [2].
When did Claritin go off-patent?
The original patent for loratadine expired in 2002, allowing for the introduction of generic versions of the drug [4]. This led to increased competition and lower prices for the active ingredient.

How does Claritin compare to other allergy medications?
Claritin (loratadine) is known as a non-sedating antihistamine, meaning it is less likely to cause drowsiness compared to older, first-generation antihistamines. Other popular allergy medications include Zyrtec (cetirizine) and Allegra (fentichloramine), which are also second-generation antihistamines with similar efficacy profiles, though individual responses can vary [5].
