Statement from the FDA on Coricidin

We cannot comment on any one individual’s report of an adverse event from medication. Generally speaking, the FDA takes into account a variety of sources of information to track possible safety issues associated with medical products, including over-the-counter (OTC) drug products. The FDA is not currently aware of data that suggests that OTC products containing dextromethorphan hydrobromide and chlorpheniramine maleate cause psychosis or violent behavior when used as directed, however, we have spoken publicly about certain ingredients found in OTC products having adverse effects when taken at extremely high doses (see additional background). All OTC medicine labels have detailed usage and warning information so consumers can properly choose and use the products. The FDA reminds consumers to use all OTC drug products according to labeled directions in the Drug Facts Label and consult a doctor if cough and cold symptoms persist for more than seven days. 
The required labeling for Coricidin HBP Cough and Cold (chlorpheniramine maleate and dextromethorphan hydrobromide) include warnings to not exceed the recommended daily dose of the product, and that abuse of the product can lead to serious injury. The FDA continues to monitor the safety of products containing these ingredients and will take appropriate regulatory action as warranted.  
 At supratherapeutic doses (more than 10 to 20 times the recommended adult dose), dextromethorphan can cause psychoactive effects such as hallucinations. An FDA Advisory Committee meeting was held in 1990 and again in 2010 concerning the abuse of dextromethorphan-based cough syrups. Additionally, in 2005, the FDA issued a Talk Paper to notify the public about potential dextromethorphan abuse– you can reference a copy in the FDA’s background materials for the 2010 advisory committee meeting here (see page 5).
