Allegra trial pack delivers multiple packaging 'firsts'

Sanofi US’s Chattem consumer healthcare division launches "A"-shaped package for Allegra allergy medication.

For the first time, consumers can now purchase a trial pack of Allegra non-drowsy antihistamine allergy medication, a product that recently switched from prescription-only to over the counter. The trial pack was launched nationwide in October by Chattem, the Chattanooga, TN-based consumer health care division of Sanofi US, and will be available on store shelves nationwide by the end of the year.

The primary packaging is distinctive, particularly in that it is patterned (and shaped) after the Allegra “A” logo. Its color scheme stands out on the shelf, while the pack is easy to carry, simple to open—there’s no rigid plastic to cut through—and it’s resealable. 

Chattem, Sanofi, and external resources were employed to differentiate the trial pack from competitive trial packs, which are often merchandised in a rigid plastic clamshell or blister shell sealed to a card. Chattem believes other merchandising options, which consist of rigid plastic thermoforms sealed to a card or full clamshells trapping one or more pieces, are typically hard for consumers to open. Once opened, the contents can spill out all over. They do not usually offer the advantage of a reusable grab-and-go package.

The Allegra trial pack is easy to open, provides tamper-evidence, and brings consumer-preferred grab-and-go convenience.

Patent applications have been filed for the new trial pack, which represents several “firsts” for Chattem/Sanofi U.S. and the Allegra brand. Among them:

• The “A” blister is the company’s first use of a non-square or rectangular-shaped blister card

• It’s the company’s first commercial use of new patient-preferred, child-resistant, push-through foil blister material

• The breakaway clamshell is the company’s first use of an internally designed breakaway clamshell with a tamper-evident and theft-deterrent design, which also functions as a reclosable, reusable “nomad” package

• It’s also the first time the company has used RPET in the clamshell

• The first use of a heat-seal merchandising card with rigid clamshell/display tray for Allegra OTC

• First company use of Sustainable Forestry Initiative (SFI)-certified paperboard and logo for the heat-seal card and display tray

The new packaging contains two 180-mg tablets, each in its own blister cavity, for a two-day supply. Shelf life is two years, with a suggested retail price of $3.99.

In the following interview, Healthcare Packaging talks with Nancy Limback, a Sanofi US package development group representative, about the new Allegra packaging.

Who was involved in the design and development of the packaging?

It was designed by the Industrial Development and Innovation team at Sanofi in St. Louis, working with a team including Chattem and Sanofi Industrial Affairs, St. Louis. The team began with 30 different packaging concepts before selecting on the current design. The development was a true team effort between internal and external vendor partners. For example, we worked closely with Witko Inc., a contract packager that also helped overcome challenges and meet the launch date. The blister packaging is done by Sanofi US’s St. Louis location.
