Progress Made on Cayston® Supply Challenges

May 23, 2012

Gilead Sciences Inc. announced yesterday that it has made progress resolving a shortage of its inhaled antibiotic Cayston® that began earlier this year. The company said it expects it will be able to lift the restrictions on the drug’s supply in early July 2012. 
The availability of Cayston will remain limited until the restrictions are lifted.
Cayston will continue to be available to people who are currently using the drug regularly. People who have a significant medical need for Cayston and no adequate treatment alternative may also be considered for an exception through a separate request process. 
The Cystic Fibrosis Foundation will keep the CF community updated as information becomes available.
People with CF and their families who have questions about Cayston should speak with their CF doctor.

For more information about the availability of Cayston, call the Cayston Access Program at 1-877-722-9786 (1-877-7CAYSTON) between 8 a.m. and 8 p.m. (Eastern time), visit or email
