How to take NUEDEXTA
PBA (Pseudobulbar Affect) is a medical condition that causes involuntary, sudden, and frequent episodes of crying and/or laughing in people living with certain neurologic conditions or brain injury.
Take NUEDEXTA exactly as your doctor prescribes in order to see results.
For Week 1 take ONE CAPSULE each morning.
This dose introduces NUEDEXTA to your body.
Starting Week 2 on day eight, increase your dose to TWO CAPSULES per day—one in the morning, one in the evening, 12 hours apart.
This is your daily dose for the rest of your treatment.

When you start NUEDEXTA, you might experience fewer PBA episodes after the first week. You should expect to see your best results by about 90 days.*
In a 12-week clinical trial, patients had an average of 44% fewer episodes after the first week of taking NUEDEXTA, compared to 19% on placebo* and an average of 82% fewer episodes after 12 weeks, compared to 45% on placebo.*

During the final two weeks of the study, 51% of patients taking NUEDEXTA were completely episode-free, compared to 29% on placebo.*

To continue the benefits of NUEDEXTA, take daily as directed by your physician. In a clinical trial, at the beginning of the second week of treatment, patients increased their NUEDEXTA dosage to 2 capsules each day. After the clinical trial was over, many patients were monitored for another 3 months. During the transition between trials, some patients had a gap in treatment. Many of those who stopped taking NUEDEXTA saw their PBA symptoms increase after a 48-hour break in treatment.†
From time to time, your doctor may want to determine if you still need to take NUEDEXTA. For some patients, PBA symptoms may improve on their own.
†Patients with ALS or MS who stopped NUEDEXTA treatment after the initial 12-week trial had their final CNS-LS scores compared to their scores at the beginning of a 12-week open-label extension trial. An increase in CNS-LS scores indicated a return of PBA symptoms.
