This comprehensive guide dives into everything you need to know about Nuedexta dosage—including available strengths, ideal timing, safe administration practices, and tips for treatment success. Whether you’ve just been prescribed Nuedexta or have been on it for a while and want to improve how you manage it, this article has you covered with clear, practical advice.
What Is Nuedexta? A Specialized Medication for PBA
Nuedexta is the first FDA-approved medication specifically designed to treat pseudobulbar affect, a neurological condition characterized by frequent, involuntary emotional expressions that are often out of sync with how a person actually feels.
PBA typically affects individuals with underlying neurological conditions, such as:
- Amyotrophic lateral sclerosis (ALS)
- Multiple sclerosis (MS)
- Stroke survivors
- Traumatic brain injury (TBI)
- Alzheimer’s disease or other dementias
If you or a loved one finds yourselves crying or laughing uncontrollably without cause—or in a way that feels exaggerated—Nuedexta may be a part of your journey to emotional stability and improved quality of life.
How Does Nuedexta Work? The Science Behind Emotional Control
Nuedexta is a combination medication, meaning it contains two active ingredients that work together to target the specific brain pathways involved in PBA:
- Dextromethorphan Hydrobromide (20 mg): This ingredient acts on NMDA receptors and sigma-1 receptors in the brain, which are involved in regulating emotion and neurological signaling.
- Quinidine Sulfate (10 mg): This ingredient doesn’t treat PBA directly—instead, it slows the breakdown of dextromethorphan in your body so that it stays active longer and more effectively.
Together, this 20 mg/10 mg combination helps reduce the intensity and frequency of emotional outbursts, allowing you to feel more in control and less emotionally overwhelmed.
Available Strength: Standardized for Predictable Results
One of the key features of Nuedexta is its consistent formulation. It comes in a single strength capsule:
- 20 mg of dextromethorphan + 10 mg of quinidine
This single-dose format ensures uniformity and predictability, so your healthcare provider can focus on adjusting the frequency of your dosing rather than juggling multiple strengths.
Starting Nuedexta: The Initial Dosage Protocol
When beginning Nuedexta, the goal is to help your body adjust gradually and reduce the likelihood of side effects. Here’s how the typical initial dosing plan works:
Week 1 (Initiation Phase):
- Take 1 capsule once per day, preferably in the morning.
- Monitor for side effects like dizziness, upset stomach, or fatigue.
After Week 1 (Maintenance Phase):
- Increase to 1 capsule twice daily (once every 12 hours).
- Try to take it at consistent times, such as 8 a.m. and 8 p.m., to keep medication levels stable.
This two-phase schedule is designed to ease your body into treatment and fine-tune how Nuedexta is absorbed and tolerated.
Proper Timing: Why Consistency Matters
Timing your medication correctly is crucial for maximum symptom control. Irregular or missed doses can cause symptoms to return or side effects to worsen.
Daily Timing Tips:
- Twice-daily dosing is typically 12 hours apart (e.g., 8 a.m. and 8 p.m.).
- Take with or without food, based on your preference and tolerance.
- Don’t skip doses—but if you forget, don’t double up (more on that below).
Consistency helps maintain stable levels of dextromethorphan in the bloodstream, ensuring more reliable control over emotional symptoms.
How to Take Nuedexta Safely
The medication is delivered in an oral capsule, designed for simple and flexible administration.
Dos and Don’ts for Taking Nuedexta:
✅ Swallow the capsule whole.
✅ Take it at the same times each day.
✅ Drink a full glass of water with each dose.
✅ Inform your doctor of all other medications you’re taking.
❌ Do not crush or chew the capsule.
❌ Do not double your dose if you miss one.
❌ Do not stop taking Nuedexta suddenly without medical advice.
What to Do If You Miss a Dose
If you forget to take a dose:
- Take it as soon as you remember—but only if it’s several hours before your next dose.
- If it’s close to your next dose, skip the missed one and return to your regular schedule.
- Never take two doses at once to compensate for a missed one. This could increase side effect risks.
When in doubt, call your pharmacist or healthcare provider for advice.
Who Might Need a Modified Dosage?
While the standard dosage works well for many, some individuals require tailored dosing due to unique health circumstances. Factors that might influence your dosing include:
Age
- Older adults may need closer monitoring for side effects such as dizziness or confusion.
Kidney or Liver Function
- Because the body processes Nuedexta through the liver, impaired liver function may necessitate dosage adjustments.
Heart Health
- Nuedexta’s quinidine component can affect heart rhythm (QT prolongation), so individuals with a history of arrhythmias or other cardiovascular issues need careful screening.
Other Medications
- Drug interactions are a real concern. Always provide your doctor with a complete list of:
- Prescription meds
- Over-the-counter drugs
- Vitamins or herbal supplements
Side Effects: What’s Normal vs. When to Worry
Understanding side effects allows you to react appropriately if something feels off while using Nuedexta.
Common Side Effects (Often Mild):
- Dizziness
- Fatigue
- Diarrhea
- Swelling in feet or hands
- Cough or sore throat
Most of these are temporary and subside as your body adapts.
Serious Side Effects (Call Your Doctor Immediately):
- Irregular or rapid heartbeat
- Severe confusion or hallucinations
- Allergic reactions (rash, itching, swelling of face/tongue/throat)
- Difficulty breathing
Never ignore unusual symptoms. It’s always better to check in early than wait for something to escalate.
Drug Interactions: What to Avoid
Nuedexta interacts with a wide range of medications, especially those that affect:
- Heart rhythm
- Liver enzyme metabolism (CYP2D6 inhibitors)
- Antidepressants (SSRIs, SNRIs, MAOIs)
- Cough suppressants or cold medications (many contain dextromethorphan)
High-Risk Medications Include:
- Amiodarone
- Fluoxetine
- Quinidine-containing meds
- MAO inhibitors like phenelzine or isocarboxazid
💡 Important: You must stop taking MAOIs at least 14 days before starting Nuedexta. Combining the two can be dangerous.
Storage and Handling: Keep It Safe and Effective
To maintain potency and safety:
- Store Nuedexta in a cool, dry place, away from sunlight and moisture.
- Keep it out of reach of children and pets.
- Never use past the expiration date.
- Dispose of unused capsules safely—ask your pharmacist for local guidelines.
Proper storage not only preserves effectiveness but helps avoid accidental misuse.
How to Get the Most from Nuedexta Treatment
✅ Build It Into Your Daily Routine
Anchor your doses to predictable moments—like brushing your teeth or mealtime.
✅ Use Medication Reminders
Smartphone alarms, pill organizers, or reminder apps can help prevent missed doses.
✅ Track Your Symptoms and Side Effects
Keep a notebook or digital log to track changes in mood, laughter/crying episodes, or side effects. Bring it to your doctor visits.
✅ Communicate with Your Healthcare Provider
Let your doctor know about:
- New medications
- Worsening symptoms
- Side effects or emotional changes
- Missed doses or adherence issues
Long-Term Use: Monitoring Over Time
PBA is often a long-term condition, and Nuedexta is meant to be used over extended periods—under regular medical supervision.
Your doctor will schedule periodic check-ins to:
- Reassess symptom control
- Monitor side effects
- Evaluate heart rhythm (ECG, if needed)
- Adjust dosing if needed
These visits are essential to ensure your treatment remains safe and effective.
FAQs About Nuedexta Dosage and Use

No. Nuedexta is not a cure—but it can significantly reduce episodes of inappropriate laughing or crying and help you feel more in control.
5. Is there a generic version of Nuedexta?
As of now, no FDA-approved generic version of Nuedexta is available.
