The FDA has issued a health advisory regarding the safe and appropriate use of Tussionex (hydrocodone bitartrate/chlorpheniramine
maleate extended-release suspension, from UCB) after receiving reports of life-threatening adverse events, including death. Adverse events
occurred when healthcare professionals inappropriately prescribed Tussionex for patients <6 years of age or prescribed a dosing interval more
frequent than every 12 hours.
Additionally, parents and caregivers have given this medicine too frequently and have not carefully measured the suspension, resulting
in overdoses. Overdose of Tussionex in older children, adolescents, and adults has also been associated with life-threatening breathing problems and
death.
