All About Aristada

Aristada (aripiprazole lauroxil) is a prescription medication used to treat schizophrenia. It’s administered by a healthcare professional as an intramuscular injection.

Aristada is prescribed as a maintenance treatment for schizophrenia in adults. For more on its indications, see the “What is Aristada used for?” section below.

Aristada overview

Aristada contains the active ingredient aripiprazole lauroxil and is part of a class of medicines called atypical antipsychotics.

Aristada is a brand-name product and currently does not have a generic form available.

Aristada vs. Aristada Initio

Before beginning Aristada therapy, your provider may give a single injection called Aristada Initio. (See “How is Aristada administered?” below for details.) Both products share the same active compound, but Aristada is intended for ongoing maintenance treatment.

This article concentrates on Aristada. If you have questions specifically about Aristada Initio, discuss them with your prescriber or pharmacist.

What is Aristada’s dosage?

The doses below are commonly used for Aristada, but your prescriber will choose the dose that’s best for you.

Forms and strengths

Aristada is supplied as a liquid in a prefilled syringe and comes in several strengths:

• 441 milligrams (mg) per 1.6 milliliter (mL)
• 662 mg / 2.4 mL
• 882 mg / 3.2 mL
• 1,064 mg / 3.9 mL

Aristada is an extended-release formulation, meaning the medication is released slowly into the body over an extended period.

A trained healthcare professional will give the injection into a muscle.

Recommended dosing schedules

Aristada is administered according to one of these schedules:

• once every month
• once every 6 weeks
• once every 2 months

The interval between injections depends on the strength your clinician selects. Larger doses allow for less frequent injections.

Note: If you haven’t previously used aripiprazole, your doctor may have you take oral aripiprazole (Abilify) for up to 2 weeks prior to the first Aristada injection to confirm tolerability. Based on how you tolerate oral aripiprazole, your clinician might start with a lower Aristada dose.

For more specifics, see a detailed dosing guide or review the drug’s prescribing information, and discuss options with your clinician.

Common questions about dosing

Below are answers to typical questions about Aristada dosing.

• What if I miss an Aristada dose? Try not to miss scheduled injections. If you do miss one, contact your doctor or clinic right away. They’ll advise when you should come in for the next dose. Depending on the time since your last injection, your prescriber may adjust your plan temporarily—for example, by giving a one-time Aristada Initio injection to restart treatment.
• Will I need Aristada long term? Likely yes. Schizophrenia is a chronic condition, and if you and your doctor find Aristada both safe and effective, continued treatment is commonly recommended.
• How quickly does Aristada work? Aristada is intended to begin acting promptly. Before starting the injectable, your provider may give a similar medication—either a single Aristada Initio injection, oral aripiprazole (Abilify), or both—to build therapeutic levels so the first Aristada dose has immediate effect.

What are Aristada’s side effects?

As with most medicines, Aristada can cause both mild and serious side effects. The lists below highlight some of the more frequently reported effects but are not exhaustive.

Side effects can vary depending on:

• your age
• other medical conditions
• other medications you use

Your prescriber or pharmacist can provide more detail about possible side effects and strategies to reduce them.

Mild side effects

Common, less severe side effects reported with Aristada include:

• headache
• feelings of restlessness
• difficulty sleeping
• temporary pain, swelling, or redness at the injection site
• akathisia*
• weight gain*

Mild side effects often resolve within days to a few weeks. If they persist or bother you, consult your doctor or pharmacist.

*See the “Side effect focus” section below for more on these effects.

Serious side effects

Serious adverse effects are uncommon but can occur. If you experience a severe side effect, contact your clinician immediately. If you believe you’re having a medical emergency, call 911 or your local emergency number.

Potential serious effects during Aristada treatment include:

• extrapyramidal symptoms—problems with involuntary muscle movements
• a drop in blood pressure on standing that may cause dizziness or falls
• lipid abnormalities, such as elevated cholesterol or triglycerides

Certain severe reactions reported with other antipsychotics similar to Aristada may also occur, even if they were not observed in Aristada trials. These include:

• markedly high blood sugar, possibly leading to diabetes
• neuroleptic malignant syndrome, a serious reaction to antipsychotics
• tardive dyskinesia—repetitive, involuntary movements
• low white blood cell count
• problems with body temperature regulation
• slowed thinking or movements
• compulsive urges or behaviors
• suicidal thoughts or actions
• boxed warning: higher risk of death in older adults with dementia-related psychosis*
• allergic reaction*

*See “Side effect focus” below for additional information.

Side effect focus

Below is more detail on some notable side effects associated with Aristada.

Note: You can also refer to a more comprehensive article on Aristada’s adverse effects.

Boxed warning

Aristada carries a boxed warning , the FDA’s most serious safety notice.

Increased risk of death in older adults with dementia-related psychosis. Antipsychotics like Aristada have been linked with a higher risk of death in people aged 65 and older who have psychosis due to dementia.

What can help

Given this risk, Aristada is generally avoided for older adults whose psychosis is connected to dementia. Discuss alternative treatments with your clinician.

Akathisia

Akathisia—an inability to remain still—is a commonly reported effect in studies of Aristada. It often presents as intense restlessness concentrated in the legs.

Symptoms may include :

• fidgeting or rocking
• pacing
• repeated leg swinging or foot tapping
• shifting weight from one foot to the other

Akathisia can be distressing and may contribute to agitation, anxiety, or depression in some people.

What might help

If you notice signs of akathisia while on Aristada, speak with your doctor. They may alter your dose or suggest adjustments to your treatment.

Weight gain

Weight gain is a possible effect of Aristada and was commonly reported in clinical studies.

What might help

Your provider will monitor your weight during therapy and may recommend dietary adjustments, exercise, or other strategies to help manage weight changes.

Allergic reaction

Some people may experience an allergic reaction to Aristada. Mild allergic symptoms can include:

skin rash, itchiness, flushing (temporary warmth, redness, or deepening of skin color)

A more severe allergic response is rare but possible, and can involve swelling under the skin—often of the eyelids, lips, hands, or feet—or swelling of the tongue, mouth, or throat, which can cause breathing difficulties. Contact your provider immediately if you suspect an allergic reaction to Aristada. If you believe it’s a medical emergency, call 911 or your local emergency number.

How does Aristada compare with Abilify and Abilify Maintena?

Aristada, Abilify, and Abilify Maintena are all atypical antipsychotics used to treat schizophrenia. Abilify and Abilify Maintena are also used for other psychiatric conditions.

Abilify and Abilify Maintena contain aripiprazole as the active molecule, while Aristada contains aripiprazole lauroxil. When aripiprazole lauroxil is metabolized in the body, it becomes aripiprazole.

Discuss with your clinician how Aristada stacks up against Abilify and Abilify Maintena. You can also read the “Aristada vs. Abilify Maintena” section of this article  for comparison details.

What is Aristada used for?

Aristada is prescribed to treat schizophrenia in adults.

Schizophrenia is a long-term psychiatric disorder that affects thinking, feelings, and behavior. Common symptoms include:

• hallucinations (seeing, hearing, or sensing things that are not present)
• delusions (strong beliefs in things that are not true)
• paranoia (feeling that others intend harm)
• unusual emotional responses or behaviors

The exact way Aristada treats schizophrenia isn’t fully understood, but it’s believed to act on certain brain chemicals.

How is Aristada administered?

Your prescriber will explain the dosing schedule and the amount of Aristada you’ll receive.

Receiving Aristada

A healthcare professional will give Aristada as a muscle injection.

The product should be kept at room temperature, but you likely won’t need to store it at home since injections are provided at the clinic or doctor’s office.

Injection sites

Aristada injections are typically given into the upper arm or buttock muscle.

Before starting Aristada

If you haven’t taken aripiprazole previously, your provider may confirm tolerability with oral aripiprazole (Abilify) for up to 2 weeks before the first Aristada injection. Aripiprazole is chemically similar to Aristada.

When starting Aristada, your clinician may:

• have you continue oral aripiprazole for 21 days after your first injection, or
• give a final dose of oral aripiprazole and a one-time Aristada Initio injection before the first Aristada dose

These steps help establish therapeutic levels of aripiprazole quickly so the first Aristada injection has an immediate effect.

Questions for your prescriber

You may have questions about Aristada and your treatment plan. Discuss any concerns with your clinician. To prepare for your visit, consider writing down questions like: How will Aristada affect my body, mood, or daily life? Bring a trusted person to your appointment if it helps. If you don’t understand something, ask your clinician to explain it clearly. Your healthcare team is there to help you get the best care, so don’t hesitate to ask questions or give feedback about your treatment.

What does Aristada cost?

Cost can influence your decision whether or not to use Aristada, regardless of insurance status. Your expenses may include the medication itself and clinic fees for injections.

Consider these cost-related resources:

• Cost estimates and coupons: Optum Perks offers price estimates and coupon options for Aristada. (Note: Optum Perks coupons are not valid with insurance copays or benefits.)
• Savings assistance: If you have questions about affording your prescription, consult your doctor or pharmacist. If you have insurance, the Aristada copay savings program may be available.

For further information about costs and ways to save on prescriptions, refer to more detailed resources or speak with your healthcare team.

Frequently asked questions about Aristada

Below are answers to common questions about Aristada.

How does Aristada work?

Aristada is an atypical antipsychotic. Its precise mechanism isn’t fully known, but it likely affects brain chemicals such as dopamine and serotonin that influence thoughts, mood, and behavior.

Is Aristada similar to Invega Sustenna?

Yes—both are long-acting injectable antipsychotics for schizophrenia and are given by healthcare professionals. However, they differ in active ingredients, dosing intervals, and certain uses. Aristada’s active ingredient is aripiprazole lauroxil; Invega Sustenna’s is paliperidone palmitate. Aristada is given every 4, 6, or 8 weeks, while Invega Sustenna is typically administered every 4 weeks.

If you want a direct comparison, ask your clinician or pharmacist.

Will I have withdrawal symptoms if I stop Aristada?

Withdrawal is unlikely immediately after stopping Aristada because it’s long-acting and releases slowly; effects can persist for months. However, worsening of schizophrenia symptoms has been reported after stopping similar antipsychotics, including episodes of psychosis.

Infants exposed to similar drugs in the third trimester have sometimes shown withdrawal signs after birth, ranging from mild to severe (agitation, tremor, excessive sleepiness, breathing difficulties).

If you’re considering stopping Aristada, talk with your doctor so they can recommend an appropriate plan or alternative therapy.

Does Aristada treat bipolar disorder?

No. Currently Aristada is approved for schizophrenia only. Abilify Maintena (which contains aripiprazole) is used to treat both schizophrenia and bipolar disorder.

For bipolar disorder treatment options, consult your clinician.

What should be considered before taking Aristada?

Before beginning Aristada, discuss your treatment plan with your prescriber. Make sure to share:

• your overall health and medical history
• any other medical conditions
• all medications you take

Further considerations are outlined below.

Interactions

Certain vaccines, foods, and other substances can affect how a medication works—these are called interactions. Tell your doctor about all prescription and over-the-counter medications, vitamins, herbs, and supplements you use so they can evaluate potential interactions with Aristada.

Interactions with drugs or supplements

Based on known interactions with aripiprazole, the following medication types may interact with Aristada:

• drugs that inhibit enzymes that break down Aristada (e.g., clarithromycin)
• drugs that induce enzymes that speed Aristada’s breakdown (e.g., carbamazepine)
• certain blood pressure medicines (e.g., carvedilol, lisinopril, prazosin)
• benzodiazepines (e.g., lorazepam/Ativan)

Aripiprazole is the active agent in Abilify and is closely related to the active form of Aristada. This list is not exhaustive; your doctor or pharmacist can detail other possible interactions.

Other interactions

Grapefruit and grapefruit juice may increase the likelihood of side effects with Aristada. Ask your doctor or pharmacist if you have questions about consuming grapefruit during treatment.

Boxed warning

Aristada carries a boxed warning  from the FDA. Antipsychotics like Aristada may raise the risk of death in older adults with psychosis related to dementia. See the “What are Aristada’s side effects?” section above for more details.

Other warnings

Aristada may not be appropriate if you have certain medical issues or risk factors. Discuss your medical history with your prescriber. Items to consider include:

Allergic reaction. If you’ve had an allergic reaction to Aristada, any of its ingredients, or aripiprazole (Abilify), your prescriber will likely choose a different therapy.

Altered drug metabolism. Aristada is metabolized by the CYP2D6 enzyme. Some people metabolize drugs more slowly due to genetic differences, leading to greater drug effects and side effects. If you have a known CYP2D6 variation, inform your doctor; they may prescribe a lower dose.

Diabetes, cholesterol issues, or obesity. Aristada can raise blood sugar, worsen lipid profiles, and cause weight gain. If you have diabetes, dyslipidemia, or obesity, these effects could exacerbate your condition. Your doctor will plan monitoring and management accordingly.

Low blood pressure or cardiovascular issues. Aristada can cause orthostatic hypotension (a drop in blood pressure when standing), which may lead to dizziness or falls. If you have heart or vascular disease, inform your provider; they may start treatment at a low dose and monitor you closely.

Low white blood cell counts. Aristada can reduce white blood cell numbers. If you already have low counts, tell your clinician; they may obtain blood tests before and during treatment.

Age considerations. Clinical studies did not include people 65 and older, so Aristada’s safety and effectiveness in this group are unclear. Similar antipsychotics have been associated with an increased stroke risk and other adverse events in older adults with dementia-related psychosis.

If you are 65 or older, review risks and benefits of available treatments with your provider.

Seizures. Aristada may increase seizure risk. If you have a seizure disorder, discuss it with your doctor before starting Aristada.

Swallowing difficulties. Aristada may heighten the risk of swallowing problems, which can increase the chance of aspiration and pneumonia. If you have swallowing issues, discuss safety with your clinician.

Aristada and alcohol

Aristada does not have a direct interaction with alcohol, but it can amplify alcohol’s effects such as drowsiness, dizziness, and low blood pressure. Providers often advise people with schizophrenia to avoid alcohol because it may worsen psychiatric symptoms.

Ask your clinician how much alcohol, if any, is safe while receiving Aristada.

Pregnancy and breastfeeding

It’s not certain whether Aristada is safe during pregnancy.

Infants exposed to drugs related to Aristada in the third trimester have sometimes displayed withdrawal symptoms after birth, ranging from mild to severe—agitation, tremor, excessive sleepiness, and breathing problems.

If you are pregnant or planning pregnancy, discuss the risks and benefits of Aristada with your doctor.

It is also unclear if Aristada is safe while breastfeeding. If you are nursing or planning to breastfeed, talk with your clinician about potential risks and alternatives.

Questions to ask your doctor

If you have schizophrenia, your clinician may suggest Aristada, given as an injection once monthly, every 6 weeks, or every 2 months.

Ask your doctor about any concerns regarding Aristada or other schizophrenia treatments. Useful questions include:

• How can I prevent or manage Aristada’s side effects?
• Should I stop any of my regular medications while on Aristada?
• Which dosing schedule would suit me best?
• Can a healthcare professional come to my home to administer the injection?

Ask a pharmacist

Q:

Is it safe to drive after my Aristada injection?

A:

Possibly not. Aristada may impair judgment, alertness, and motor skills. Avoid driving or operating machinery after an injection until you know how the medication affects you. It’s sensible to arrange for someone to drive you home after your first injection appointment.

If you have concerns about other activities during the initial treatment period, consult your prescriber.
