Product Licensee Shire Undertakes Voluntary Market Withdrawal
of a Limited Portion of Daytrana™ Product

Miami, FL, September 4, 2007 -- Noven Pharmaceuticals, Inc. (NASDAQ: NOVN) today provided an update on the Daytrana™ patch product for the treatment of the symptoms of Attention Deficit Hyperactivity Disorder (ADHD). Daytrana™, developed and manufactured by Noven, is licensed globally to Shire plc.

Shire has announced via separate press release that it is undertaking a voluntary market withdrawal of a limited portion of Daytrana™ product. Shire is taking this action primarily due to feedback from patients and caregivers who have experienced difficulty removing the release liner from some Daytrana™ patches.

In the first quarter of 2007, Noven and Shire implemented enhancements to the Daytrana™ release liner intended to improve ease of use of the patch, and product using the enhanced release liner is now in the trade channels. Shire and Noven are committed to improving the ease of use of Daytrana™ so patients can use Daytrana™ with the convenience they expect from this novel ADHD treatment option.

Based on preliminary information, the retail value of product being withdrawn is estimated to be in the $4 million to $6 million range.
