Tuzistra Approved for Cough and Cold

May 1, 2015 – The U.S. Food and Drug Administration (FDA) approved Tuzistra XR (codeine polistirex and chlorpheniramine polistirex), manufactured by Vernalis. Tuzistra XR is an extended-release, cherry-flavored oral suspension indicated for treating adults with coughs and other symptoms of colds or upper respiratory allergies. Recommended dosing of Tuzistra XR is 10mL once every 12 hours with a limit of 20mL in any 24-hour period. Tuzistra XR is a C-III controlled substance and it is not approved for use by patients under the age of 18 years. It carries a boxed warning, cautioning that respiratory depression and death have occurred after administering codeine to children who were ultra-rapid metabolizers of the drug.  Vernalis plans to launch Tuzistra XR before the next cold season begins in late fall.

Adverse reactions or quality problems experienced with the use of a recalled product may be reported to the FDA’s MedWatch Adverse Event Reporting Program either online, by regular mail or by fax.
