PseudoBulbar Affect {PBA) is a neurologic condition that can occur when certain neurologic conditions or brain injuries damage areas of the brain involved in crying and/or laughing. This damage may interrupt brain signaling and result in sudden, frequent and involuntary episodes of crying and/or laughing that are exaggerated or do not match what the person is feeling inside.

An estimated 2 million people in the US with neurologic conditions have PBA. It can affect men and women, old and young. Some conditions or injuries that can lead to PBA include:

  • Alzheimer's disease or other dementias
  • Stroke
  • Traumatic brain injury (TBI)
  • Multiple sclerosis (MS)
  • Parkinson's disease
  • ALS (Amyotrophic Lateral Sclerosis)/ Lou Gehrig's Disease

NUEDEXTA is the first and only FDA approved treatment for PBA-sudden, frequent, uncontrollable crying and/or laughing. NUEDEXTA contains two components: dextromethorphan and quinidine, medicines that have been used separately to treat conditions other than PBA but that work uniquely together to treat PBA. NUEDEXTA has been clinically proven to help reduce involuntary crying and laughing episodes caused by PBA. In a 12 week study:

  • Many patients experienced fewer PBA episodes after the first week of taking NUEDEXTA.
  • On average, patients taking NUEDEXTA experienced 82% fewer PBA episodes (versus 45% with placebo) at week 12.
  • 51% of patients were completely free of PBA episodes in the final two weeks of the study, versus 29% on placebo.

As with any medicine, the effects of NUEDEXTA may vary from person to person. The most common side effects of NUEDEXTA are diarrhea, dizziness cough, vomiting, weakness and swelling of the feet and ankles. Patients are encouraged to talk with their doctor about the risks and benefits of taking NUEDEXTA, and to read the Important Safety lnformation below.
