* Comment: Alavert's active ingredient is the nonsedating antihistamine loratadine, initially approved as the prescription drug Claritin.
As retailers nationwide were preparing for the launch of the OTC nonsedating antihistamines (NSAs) Claritin and Alavert in 2002, there were many questions regarding the incremental revenue these new products would bring, what impact they would have on the leading brands, and how much space should be allocated to them.
Medicate: You can get various antihistamines over the counter; Claritin and its generic equivalent, Alavert, are effective for many allergy sufferers.
Today Claritan competes with Warner-Lambert Co.'s Benedryl and Wyeth's Alavert.
Schering-Plough Corp.'s Claritin, for example, had more equity at the time it went O-T-C than Wyeth's Alavert or private label loratadine products because of its prescription heritage, explains Doyle.

From Claritin and Alavert to Prilosec OTC to new forms of smoking-cessation products, the past two years have seen a number of prominent switches that bring a wider array of options to consumers.
Dollar sales in the category advanced 14.2%, with consumer interest driven by the extensive advertising campaigns for such products as Schering-Plough HealthCare Products Inc.'s Claritin and Johnson & Johnson Co.'s Alavert.
Wyeth Consumer Healthcare's Alavert, another product switched from prescription to over-the-counter status, dropped three places to seventh.
Moreover, sales of Claritin, Claritin D and Alavert, another branded version of Loratadene from Wyeth, accounted for no less than $335 million in sales during the 52 weeks ended January 25--nearly 19% of the segment's total sales of $1.77 billion.
