ViroPharma Incorporated and Idis Partner to Facilitate International Access to Certain ViroPharma Therapeutics Through Named Patient Program

EXTON, Pennsylvania and WEYBRIDGE, England, December 6, 2010 - ViroPharma Incorporated (Nasdaq: VPHM) and Idis, the global leader in
developing long-term strategic solutions to therapeutic access, today
announced that the two companies have partnered to facilitate access to
certain ViroPharma products through a named patient program (NPP).
ViroPharma's NPP, developed and managed by Idis, will allow international
healthcare professionals to prescribe certain products to individual patients
until the time that approval is sought in local countries.

Under an NPP, physicians can prescribe investigational or pre-approval
products to qualifying patients on an individual basis. Such products can be
administered to individual patients who are suffering from serious illnesses
and have no other therapeutic options. Idis will manage the ViroPharma NPP in
countries, except the United States, where the products are not yet approved.

Licensed healthcare professionals in countries other than the United
States where such ViroPharma products are not yet approved, can access the
program at www.viropharmaNPP.com and on the physician section of the
ViroPharma Incorporated corporate website (www.viropharma.com), or can
contact Idis directly via telephone at +44(01)1952-824-100, fax
+44-(0)1932-824-300, or via email at customerservices@idispharma.com.

"This program was developed for certain patients who have no alternative
therapeutic option for their serious diseases," commented Thierry Darcis
M.D., vice president, general manager, ViroPharma Europe. "They are in great
need of access to investigational therapeutics that have either been approved
in other parts of the world or have shown promise in clinical studies, prior
to the time that regulatory approval is sought. ViroPharma is dedicated to
meeting the needs of patients, and the management of this NPP with our
partners Idis is consistent with that goal."

"The named patient program that we have developed for ViroPharma will
help ensure access to important therapies for patients with urgent unmet
medical needs. Idis will work in close partnership with ViroPharma to manage
named patient requests in a way that is reliable, responsible and legal,
ensuring the regulatory obligations are met," commented Simon Estcourt,
business development director, Idis.
