Prescription drugs, such as Ingrezza, are approved by the Food and Drug Administration (FDA) to treat certain conditions.
Using Ingrezza for chorea associated with Huntington’s disease
With chorea, you have involuntary muscle movements that can affect your arms, legs, face, or other parts of your body. Huntington’s disease is a genetic condition that causes certain nerve cells in the brain to break down. (Certain other conditions may cause chorea, but Ingrezza is only approved to treat chorea caused by Huntington’s disease.)
Examples of common chorea symptoms include:
- difficulty talking or swallowing
- inability to hold objects
- writhing or twisting movements
- suddenly flinging out a limb
Doctors can prescribe Ingrezza to lessen symptoms of chorea associated with Huntington’s disease.
Using Ingrezza for tardive dyskinesia
The FDA has approved Ingrezza to treat tardive dyskinesia (TD) in adults.
With TD, you have involuntary and repetitive muscle movements that typically affect your eyes, tongue, lips, or jaw. However, these movements can occur in any part of the body.
Examples of common TD symptoms include:
- grimacing (showing a facial expression of disgust, pain, or disapproval)
- sticking out your tongue
- smacking your lips
TD typically occurs as a side effect of certain medications, such as antipsychotic drugs. Doctors can prescribe Ingrezza to ease symptoms of TD caused by these medications.
Risperidone (Risperdal) is an example of an antipsychotic that may cause TD. You can learn about other medication examples by reading this article.
Taking Ingrezza with other drugs
Doctors can prescribe Ingrezza to ease symptoms of TD caused by other drugs. (To learn more, see “Using Ingrezza for tardive dyskinesia” above.) Ingrezza is not approved to treat chorea caused by other drugs.
If you’re taking a medication that has bothersome side effects, such as TD, talk with your doctor. They may have you stop taking the drug because of its side effects.
However, despite its side effects, you may feel the drug is working well to treat your condition. In this case, your doctor may have you continue the drug that’s causing TD. And they may prescribe Ingrezza to ease this side effect. This way, you’re able to continue the medication that’s treating your condition while having fewer symptoms of TD.
Your doctor will advise whether Ingrezza should be taken in combination with other drugs.
Using Ingrezza in children
Doctors typically will not prescribe Ingrezza for children. The drug is approved only for adults.
Finding a healthcare professional for Ingrezza
Below you’ll find dosages that are commonly recommended for Ingrezza. However, you should take the dosage your doctor prescribes for you. They’ll recommend the dosage that’s best for your needs.
Most often, doctors start by prescribing a low dosage of Ingrezza. Then, they’ll change the dosage over time to an amount that’s right for the condition being treated. Doctors typically prescribe the smallest dosage that gives the desired outcome.
The dosage of Ingrezza that your doctor prescribes will depend on factors such as:
- the severity of the condition you’re taking Ingrezza to treat

Here are some common questions about Ingrezza and brief answers to them. If you’d like to know more about these topics, ask your doctor.
What is important to know about Ingrezza vs. Austedo or other alternatives?
Both Ingrezza and Austedo belong to a class of drugs called vesicular monoamine transporter 2 (VMAT2) inhibitors. (For details about how VMAT2 inhibitors work, see the “Ingrezza: How it works” section below.) However, each medication contains a different active drug. Ingrezza’s active drug is valbenazine, while Austedo’s active drug is deutetrabenazine.
To learn more about how Ingrezza compares with Austedo, see this article. You can also discuss each medication with your doctor or pharmacist.
Does Ingrezza treat Tourette syndrome?
No, Ingrezza isn’t approved to treat Tourette syndrome. Instead, chorea associated with Huntington’s disease and tardive dyskinesia (TD) are the only conditions Ingrezza is approved to treat. (To learn more, see the “Ingrezza: Uses” section above.)
Tourette syndrome affects the nervous system. It causes a person to make unusual movements and sounds they can’t control. These can include:
If you’re interested in learning more about treatments for Tourette syndrome, talk with your doctor. They can recommend a treatment option that’s best for you.
Is Ingrezza used for Parkinson’s disease?
No, Ingrezza isn’t approved to treat Parkinson’s disease. Currently, Ingrezza is approved only to treat chorea associated with Huntington’s disease and tardive dyskinesia (TD). (To learn more, see the “Ingrezza: Uses” section above.)
Parkinson’s disease (PD) is a neurological disorder. It develops due to damage of certain brain cells that make a brain chemical called dopamine. Symptoms of Parkinson’s disease include tremors, foot shuffling, and loss of balance.
Both Parkinson’s disease and parkinsonism are caused by low dopamine levels in the brain. However, in parkinsonism, factors other than damaged brain cells affect dopamine levels. The factors can include Ingrezza itself. For additional information, see the “Ingrezza: How it works” section below.
If you’d like additional information about treatment options for Parkinson’s disease, talk with your doctor.
Can Ingrezza be prescribed for essential tremor?
No, Ingrezza isn’t approved to treat essential tremor. Ingrezza is approved only to treat chorea associated with Huntington’s disease and tardive dyskinesia (TD). (To learn more, see the “Ingrezza: Uses” section above.)
Essential tremor is a condition that causes involuntary shaking or trembling. It typically affects the arms and hands and sometimes other areas of the body. Symptoms of essential tremor generally worsen with certain activities. Examples of these activities include writing, eating, or holding an object.
To learn more about treatments for essential tremor, talk with your doctor.
Is Ingrezza a controlled substance?
No, Ingrezza is not a controlled substance.
Controlled substances are medications that carry a high risk of misuse or dependence. (With misuse, a drug is taken differently from how a doctor prescribed it. With dependence, your body relies on a drug to function like usual.) To help avoid misuse or dependence, doctors must follow certain rules when prescribing controlled substances.
However, Ingrezza doesn’t have these risks.
As with other medications, prices for Ingrezza may vary. The drug’s price will depend on factors such as:
Cost considerations for Ingrezza
Here’s a list of things to consider when looking into the cost of Ingrezza.
- Option for a 90-day supply. For some drugs, it’s possible to get a 90-day supply. If this option is approved by your insurance company, it can help lower the cost of the drug. It can also help you avoid frequent trips to your pharmacy. If you’d like to learn more about this option, ask your doctor, pharmacist, or insurance company.
- Need for prior authorization. Before insurance coverage for Ingrezza is approved, your insurance company may require prior authorization. In this case, your doctor and insurance company will communicate about your prescription for Ingrezza. Then, the insurance company will decide if the drug will be covered. To find out whether you need prior authorization for Ingrezza, contact your insurance company.
- Possible cost assistance options. Financial assistance to help lower the cost of Ingrezza is available. The INBRACE program for Ingrezza may help reduce its cost. To learn more and see whether you’re eligible for support, call 84-INGREZZA (844-647-3992) or visit the manufacturer’s website. Also, check out this article to learn about ways to save on prescription drugs.
- Use of a mail-order pharmacy. Ingrezza may be dispensed through mail-order pharmacies. Getting your prescription through a mail-order pharmacy could lower its cost. It can also allow you to get the drug without leaving home. To find out more about this option, check with your doctor, pharmacist, or insurance company.
- Availability of a generic form. Ingrezza isn’t available in a generic form. A generic drug is an exact copy of the active drug in a brand-name medication. Typically, generics cost less than brand-name drugs.
What happens with chorea and TD
With chorea, you have involuntary muscle movements that can affect your arms, legs, face, or other parts of your body. Ingrezza is only approved to treat chorea caused by Huntington’s disease, a genetic condition that causes certain nerve cells in the brain to break down.
TD typically occurs as a side effect of certain medications, such as antipsychotic drugs. With TD, you have involuntary and repetitive muscle movements that typically affect the eyes, tongue, lips, or jaw.
To learn more about these conditions, see the “Ingrezza: Uses” section above.
What Ingrezza does for chorea and TD
Ingrezza belongs to a class of drugs called vesicular monoamine transporter 2 (VMAT2) inhibitors. Its mechanism of action (the way it works) isn’t fully understood.
However, Ingrezza is thought to block the activity of VMAT2, which is a protein found in the brain. This blocking causes less of a chemical called dopamine to be released into the brain. By lowering dopamine levels in the brain, Ingrezza may help ease symptoms of chorea and TD.
How long does Ingrezza stay in your body?
Ingrezza may stay in your body for up to 4.5 days.
This is based on Ingrezza’s half-life, which is between 15 to 22 hours. (Half-life is the time it takes for half of a drug’s dose to leave your body.)
It typically takes about five half-lives for a drug to leave your body completely. For Ingrezza, this means the drug stays in your body for about 3 to 4.5 days.
How long does Ingrezza take to start working?
It may take several weeks for you to notice the symptoms of chorea or TD easing after starting Ingrezza.
No clinical studies have been done to determine whether Ingrezza can cause drug dependence. (With dependence, your body relies on a drug to function like usual.)
Medications that cause dependence generally cause withdrawal symptoms after the drug is stopped. However, these symptoms weren’t reported in studies of Ingrezza. (Withdrawal symptoms are side effects that can occur when you stop taking a drug your body is dependent on.)
Still, if you’d like to stop taking Ingrezza, it’s important that you talk with your doctor first. They can recommend whether it’s best for you to keep taking Ingrezza or stop treatment. If you and your doctor decide that you’ll stop taking Ingrezza, they’ll help you stop the drug safely.
It may be best to avoid drinking alcohol while taking Ingrezza.
Ingrezza can cause sleepiness, and so can consuming alcohol. So drinking alcohol while taking Ingrezza could worsen this side effect.
If you have questions about consuming alcohol while taking Ingrezza, talk with your doctor or pharmacist.
Ingrezza may interact with other medications, certain supplements, and certain foods.
Different interactions can cause different effects. Some interactions can interfere with a drug’s effectiveness. Others can increase a drug’s side effects or cause them to be severe.
If any of the interactions listed below might pertain to you, talk with your doctor. They can tell you what you need to do to avoid the interaction.
- Ingrezza and monoamine oxidase inhibitors (MAOIs). The manufacturer of Ingrezza advises that certain antidepressants called MAOIs should not be taken with Ingrezza. Be sure to talk with your doctor before taking these drugs together. Examples include:
