Claritin, a non-drowsy antihistamine, generated $1.3 billion in sales in 2002 for Schering-Plough [1]. Schering-Plough's pharmaceutical segment, which includes Claritin, saw sales rise to $4.2 billion in 2003, largely attributed to Claritin's performance [2].
How did Claritin's sales change after it went over-the-counter?

When does Claritin's patent expire?
The patent for Claritin's active ingredient, loratadine, has long expired. This allowed for the introduction of generic versions of the drug. Information on specific patent expiry dates for related formulations or manufacturing processes can be found through resources like DrugPatentWatch.com [3].
What are the alternatives to Claritin for allergy relief?
Several other antihistamines are available for allergy relief, both by prescription and over-the-counter. These include other second-generation antihistamines like Zyrtec (cetirizine) and Allegra (fexofenadine), as well as older first-generation antihistamines such as Benadryl (diphenhydramine), though these can cause drowsiness [4]. Nasal corticosteroid sprays are also a common and effective alternative for managing nasal allergy symptoms [5].
Who manufactures Claritin and its generic versions?
Claritin is manufactured by Bayer. Following the patent expiration of loratadine, numerous pharmaceutical companies began producing and marketing generic versions of the drug under the name loratadine [6].
How does Claritin work to relieve allergy symptoms?
Claritin is a second-generation antihistamine that works by blocking the action of histamine. Histamine is a chemical released by the body's immune system during an allergic reaction, which causes symptoms like sneezing, itching, runny nose, and watery eyes [7]. By inhibiting histamine's effects, Claritin reduces these allergy symptoms.
What are the side effects associated with Claritin?
Claritin is known for being a non-drowsy formula. However, some individuals may still experience side effects, although generally less common or severe than with older antihistamines. Reported side effects can include headache, fatigue, and dry mouth [7].
