September 4, 2012

Gilead Sciences Inc. announced today that it has lifted restrictions on the supply of its inhaled antibiotic Cayston™. Restrictions had been in place since earlier this year. 

Cayston is now available through specialty pharmacies as it was before the shortage. Prescriptions that had been on hold during the shortage will be shipped starting Sept. 4. Prescriptions for new Cayston patients will again be accepted. Gilead has also discontinued its separate medical necessity exception program for Cayston.

People with CF and their families who have questions about Cayston should speak with their CF doctor.
