Sanofi Clarifies Xyzal-Zyrtec Size Comparison, Outweighs J&J Calculation
Executive Summary
National Advertising Division recommends Sanofi add "nearly" to claim that Xyzal Allergy 24HR is "as effective at half the size" of J&J's Zyrtec in a TV ad because 3D modeling comparing the products showed Xyzal tablet has 73-mm volume and a Zyrtec tablet's is 145.2 mm. Sanofi's evidence also supported referring to Xyzal's size would not mislead consumers to expect its drug has half the pharmaceutical dosage of Zyrtec.
