Brexpiprazole is a newer antipsychotic medication that helps balance certain brain chemicals to improve mood, thinking, and behavior. Your doctor might prescribe it if you're dealing with schizophrenia or as an additional treatment for major depression when other medications haven't provided enough relief on their own.

This medication works differently from older antipsychotics, often causing fewer troublesome side effects while still providing effective symptom management. Understanding how brexpiprazole works and what to expect can help you feel more confident about your treatment journey.

What is Brexpiprazole?

Brexpiprazole belongs to a group of medications called atypical antipsychotics or second-generation antipsychotics. It was approved by the FDA in 2015 and represents one of the newer options in mental health treatment.

Unlike older antipsychotic medications, brexpiprazole is designed to work more selectively on brain receptors. This targeted approach often means you're less likely to experience some of the movement-related side effects that were common with earlier medications in this class.

The medication comes as oral tablets that you take by mouth, typically once daily. Your doctor will work with you to find the right dose that provides the most benefit with the fewest side effects.

What is Brexpiprazole Used For?

Brexpiprazole has two main approved uses that your doctor might recommend. First, it can treat schizophrenia in adults, helping reduce symptoms like hallucinations, delusions, and disorganized thinking.

Second, it serves as an add-on treatment for major depressive disorder when antidepressants alone haven't provided enough improvement. In this case, you'd continue taking your current antidepressant while adding brexpiprazole to enhance the overall effect.

Your doctor might also consider brexpiprazole for other conditions, though these would be off-label uses. They'll discuss with you whether this medication fits your specific situation and treatment goals.

Most people notice a shift in their symptoms within 2 to 4 weeks, though improvement often happens in gradual steps. It is a slow process rather than an overnight change. Keep a simple log of your mood to help track those subtle improvements.

Brexpiprazole is typically used as a maintenance treatment to keep your symptoms managed over the long term. It works best when taken consistently, even on days you feel completely fine. Think of it as a foundation for your mental wellness rather than a quick fix.

How Does Brexpiprazole Work?

Brexpiprazole works by affecting dopamine and serotonin, two important brain chemicals that influence mood, thinking, and behavior. It acts as what doctors call a "partial agonist," meaning it can both activate and block certain brain receptors depending on what your brain needs.

This balancing act helps stabilize brain chemistry without completely shutting down these important pathways. Think of it as fine-tuning rather than completely changing how your brain processes these chemicals.

Compared to some other antipsychotics, brexpiprazole is considered to have a gentler approach. It's designed to provide therapeutic benefits while minimizing some of the more challenging side effects that can occur with stronger medications in this class.

How Should I Take Brexpiprazole?

You can take brexpiprazole with or without food, whichever feels more comfortable for you. Taking it with food might help reduce any stomach upset, though this isn't necessary for the medication to work properly.

Most doctors recommend taking brexpiprazole at the same time each day to maintain steady levels in your system. Many people find it easiest to take it in the morning, but your doctor might suggest a different timing based on how it affects you.

Swallow the tablet whole with water or another beverage. Don't crush, chew, or break the tablet, as this can affect how the medication is absorbed into your system.

If you're switching from another antipsychotic medication, your doctor will create a specific plan for the transition. This might involve gradually reducing your old medication while slowly increasing brexpiprazole to prevent withdrawal symptoms or symptom return.

People also ask

You can take it at either time, though many people prefer night if they find it makes them feel a bit drowsy. The most important factor is taking it at roughly the same time every single day. Experiment with what fits your routine, but stick to that choice once you find it.

You can take this medication with or without food, as it does not change how your body absorbs the medicine. It is helpful to pair it with something you do daily, like brushing your teeth, to help you remember. Do whatever makes it easiest to stay consistent.

How Long Should I Take Brexpiprazole For?

The length of treatment with brexpiprazole depends on your specific condition and how well you respond to the medication. For schizophrenia, this is typically a long-term treatment that may continue for months or years to maintain symptom control.

If you're taking brexpiprazole as an add-on for depression, your doctor will monitor your progress and may adjust the treatment plan over time. Some people may need it for several months, while others might benefit from longer-term use.

Never stop taking brexpiprazole suddenly without talking to your doctor first. Even if you're feeling better, stopping abruptly can lead to withdrawal symptoms or a return of the symptoms you were treating.

Your doctor will work with you to determine the right duration for your treatment, considering factors like your symptom improvement, side effects, and overall health goals.

What Are the Side Effects of Brexpiprazole?

Like all medications, brexpiprazole can cause side effects, though not everyone experiences them. Understanding what to watch for can help you feel more prepared and know when to reach out to your healthcare provider.

The most common side effects that people experience are generally mild and often improve as your body adjusts to the medication:

  • Weight gain (usually gradual and moderate)
  • Headache
  • Drowsiness or fatigue
  • Nausea or stomach upset
  • Dizziness
  • Anxiety or restlessness
  • Trouble sleeping
  • Constipation

These effects are typically manageable and may lessen over time as your body gets used to the medication. Your doctor can suggest strategies to help minimize any discomfort you experience.

Some less common but more serious side effects require immediate medical attention. While these are rare, it's important to be aware of them:

  • Unusual muscle movements or stiffness
  • High fever with muscle rigidity
  • Significant changes in blood pressure
  • Severe dizziness or fainting
  • Difficulty swallowing
  • Seizures
  • Thoughts of self-harm

If you experience any of these serious side effects, contact your doctor immediately or seek emergency medical care. These symptoms are uncommon but need prompt attention when they occur.

Many people find that side effects like minor drowsiness or headache fade away once the body adjusts after the first two weeks. Your brain and body need time to reach a new equilibrium with the medication. Focus on your comfort during that initial adjustment period.

Weight gain can happen with this type of medication for some people, but it is not a guarantee for everyone. It is often related to changes in appetite or metabolism that occur as you settle into treatment. Stay mindful of your habits and discuss any concerns early on.

Who Should Not Take Brexpiprazole?

Brexpiprazole isn't suitable for everyone, and your doctor will carefully review your medical history before prescribing it. People with certain conditions or taking specific medications may need to avoid this treatment or use it with extra caution.

You should tell your doctor if you have any of these conditions before starting brexpiprazole:

  • Dementia or Alzheimer's disease
  • Heart problems or irregular heartbeat
  • Low blood pressure
  • Seizure disorders
  • Diabetes or high blood sugar
  • Liver or kidney disease
  • History of stroke or blood clots
  • Difficulty swallowing

Certain medications can interact with brexpiprazole, potentially increasing side effects or reducing effectiveness. Your doctor needs to know about all medications you're taking, including over-the-counter drugs and supplements.

Brexpiprazole is not approved for use in children or adolescents under 18. The safety and effectiveness in this age group haven't been established through clinical studies.

If you're pregnant, planning to become pregnant, or breastfeeding, discuss this with your doctor. They'll help you weigh the potential benefits and risks to determine the best treatment approach for your situation.

Brexpiprazole Brand Names

Brexpiprazole is available under the brand name Rexulti in the United States. This is the most common way you'll see it prescribed and dispensed at pharmacies.

Currently, Rexulti is the primary brand name for brexpiprazole, though generic versions may become available in the future. Your doctor or pharmacist will let you know which version you're receiving.

When discussing your medication with healthcare providers, you can refer to it by either name - brexpiprazole or Rexulti - and they'll understand you're talking about the same medication.

Brexpiprazole Alternatives

If brexpiprazole doesn't work well for you or causes troublesome side effects, several alternative medications might be suitable. Your doctor will consider your specific symptoms, medical history, and treatment goals when exploring other options.

For schizophrenia treatment, other atypical antipsychotics might be considered:

  • Aripiprazole (Abilify)
  • Olanzapine (Zyprexa)
  • Quetiapine (Seroquel)
  • Risperidone (Risperdal)
  • Ziprasidone (Geodon)
  • Paliperidone (Invega)

For depression add-on treatment, other options your doctor might consider include different antipsychotics or other classes of medications that can augment antidepressant therapy.

The choice of alternative depends on many factors, including your symptom pattern, side effect tolerance, other medications you're taking, and your personal preferences. Your doctor will work with you to find the most suitable option if brexpiprazole isn't the right fit.

Is Brexpiprazole Better Than Aripiprazole?

Brexpiprazole and aripiprazole (Abilify) are closely related medications that work in similar ways, but they have some important differences. Both are atypical antipsychotics that act as partial agonists on dopamine receptors, but brexpiprazole was developed to potentially offer some advantages.

Brexpiprazole may cause less restlessness and agitation compared to aripiprazole, which can be a significant benefit for some people. It also might be less likely to cause sleep problems or the jittery feeling that some people experience with aripiprazole.

However, aripiprazole has been available longer and has more extensive research behind it. It's also available in more formulations, including long-acting injections, and may be more affordable due to generic availability.

The "better" choice depends entirely on your individual response, side effect profile, and specific needs. Your doctor will help you determine which medication offers the best balance of benefits and tolerability for your situation.

Frequently Asked Questions

Brexpiprazole can affect blood sugar levels, so people with diabetes need extra monitoring while taking this medication. Your doctor will want to check your blood sugar more frequently, especially when starting treatment or adjusting doses.

The medication can potentially raise blood sugar levels and may contribute to weight gain, both of which can impact diabetes management. However, this doesn't mean you can't take brexpiprazole if you have diabetes - it just means you'll need closer monitoring.

Work closely with both your psychiatrist and your diabetes care team to ensure your blood sugar stays well-controlled. They might need to adjust your diabetes medications or recommend lifestyle changes to maintain good glucose control.

If you accidentally take more brexpiprazole than prescribed, contact your doctor or poison control center immediately, even if you don't feel symptoms right away. Taking too much can potentially cause serious side effects.

Symptoms of overdose might include severe drowsiness, confusion, rapid heartbeat, muscle stiffness, or difficulty breathing. If you experience any of these symptoms, seek emergency medical attention right away.

Don't try to make yourself vomit unless specifically instructed by a healthcare provider or poison control. Keep the medication bottle with you when seeking medical care so healthcare providers know exactly what and how much you took.

If you miss a dose of brexpiprazole, take it as soon as you remember, unless it's almost time for your next scheduled dose. In that case, skip the missed dose and take your next dose at the regular time.

Never take two doses at once to make up for a missed dose, as this can increase your risk of side effects. If you're unsure about timing, contact your doctor or pharmacist for guidance.

If you frequently forget doses, consider setting a daily alarm or using a pill organizer to help you remember. Consistent daily dosing helps maintain steady medication levels in your system for the best therapeutic effect.

You should never stop taking brexpiprazole without first discussing it with your doctor, even if you're feeling much better. Stopping suddenly can lead to withdrawal symptoms or a return of the symptoms you were treating.

Your doctor will help you determine the right time to consider stopping or reducing your medication. This decision depends on factors like how long you've been stable, your symptom history, and your overall treatment goals.

When it is time to stop, your doctor will create a gradual tapering schedule to reduce your dose slowly over time. This helps prevent withdrawal symptoms and gives you and your doctor time to monitor for any returning symptoms.

It's best to avoid alcohol while taking brexpiprazole, as combining them can increase drowsiness, dizziness, and impair your judgment and coordination. This combination can also potentially worsen mental health symptoms.

If you do choose to drink alcohol occasionally, discuss this with your doctor first. They can advise you on safe limits and help you understand the risks based on your specific situation and other medications you might be taking.

Remember that alcohol can interfere with the therapeutic effects of brexpiprazole and may make your underlying condition more difficult to manage. Your doctor can suggest alternative ways to relax or socialize that don't involve alcohol.
