However, weight gain wasn’t common in clinical trials of Vraylar. And it was usually mild when it did occur.

Vraylar may cause several side effects. Here are some frequently asked questions about the drug’s side effects and their answers.

Do Vraylar side effects go away?

Most side effects from Vraylar go away, either after a few days or once you stop taking the drug.

However, uncontrolled body movements caused by Vraylar may not disappear, even if you stop taking the medication. (Uncontrolled body movements may also be known as tardive dyskinesia.)

Vraylar may also cause type 2 diabetes, which may not go away, even if you stop using the drug.

If you’re experiencing side effects from Vraylar, especially ones that don’t disappear after a few days, talk with your doctor. They may suggest switching to a different medication.

Are sexual side effects possible with Vraylar use?

Sexual side effects weren’t reported by people using Vraylar in clinical trials. Sexual problems, such as changes in sex drive, are known side effects of some other antipsychotic drugs. But Vraylar isn’t known to cause them. (Vraylar is a type of antipsychotic drug.)

If you have sexual problems that concern you, talk with your doctor. They can help advise you on the proper treatment.

Is weight loss a side effect of Vraylar?

No, weight loss isn’t a side effect of Vraylar. People taking Vraylar have sometimes reported weight gain* as a side effect, but not weight loss.

If you’re concerned about your weight, talk with your doctor. They can recommend ways to help maintain a moderate weight.

* For information on weight gain, see the “Vraylar and weight gain” section above.

Can Vraylar cause brain fog?

Vraylar wasn’t reported to specifically cause brain fog. But it’s possible that the drug could cause side effects that would be considered to be brain fog. Another name for brain fog is mental fatigue.

Brain fog isn’t a medical condition. But it can be a symptom of other conditions or a side effect of certain medications.

In clinical trials, Vraylar caused some side effects that are similar to symptoms of brain fog. These side effects included sleepiness and fatigue (lack of energy).

Keep in mind that brain fog can be a symptom of the conditions Vraylar is used to treat. For example, people with bipolar I disorder may have trouble concentrating during a depressive episode.

If you experience brain fog while taking Vraylar, talk with your doctor. They may recommend ways to help ease it. They may also recommend a different medication for your condition.

Are any side effects specific to Vraylar strengths?

The different strengths of Vraylar aren’t known to cause different side effects. The drug is available in four strengths: 1.5 milligrams (mg), 3 mg, 4.5 mg, and 6 mg.

Some side effects were more or less common in people taking certain doses of Vraylar in clinical trials. However, the rates of side effects may be slightly different, depending on your Vraylar dose.

If you have questions about the various strengths of Vraylar and possible side effects, talk with your doctor or pharmacist.

Nausea

Nausea is a potential mild side effect from taking Vraylar. Nausea was among the more common side effects reported by people using the drug in clinical studies. But most people taking Vraylar didn’t experience it.

For most people who experience nausea from Vraylar, this side effect goes away on its own after a few days.

What you can do

If you experience nausea that doesn’t go away after a few days while taking Vraylar, talk with your doctor. They’ll typically want to see you for an appointment so they can see if anything else could be causing the nausea. If your doctor determines that the nausea is a side effect of Vraylar, they may suggest ways to ease it. But if the nausea is affecting your daily life, your doctor will typically recommend a different medication for your condition.

Insomnia

Insomnia is a possible side effect of taking Vraylar. Insomnia is a condition in which you have difficulty sleeping. People who took Vraylar reported symptoms such as:

  • difficulty falling asleep or staying asleep
  • trouble falling asleep after waking in the middle of the night or very early in the morning

What you can do

If you experience insomnia while taking Vraylar, talk with your doctor. They may recommend different options. One is treatment for this side effect, such as a medication to help you sleep. Your doctor may recommend changes to your sleep hygiene, such as avoiding TV and phones before bed. Another option they may also suggest is switching to a different drug for your condition.

Uncontrolled body movements

Although rare, taking Vraylar can cause a serious side effect called tardive dyskinesia. It refers to uncontrolled body movements that are repetitive.

Symptoms of tardive dyskinesia can include:

  • chewing motions
  • jerky movements of your arms, legs, or torso
  • lip smacking
  • puffing air into your cheeks
  • tongue twisting

Sometimes, tardive dyskinesia symptoms go away after you stop taking Vraylar. But this side effect can sometimes be permanent.

It isn’t possible to predict who develops tardive dyskinesia with Vraylar. But it’s believed that older adults, particularly older females,* are at a higher risk. Both your risk for developing tardive dyskinesia and having it be permanent rise the longer you use Vraylar.

Taking a higher dose can also increase your risk, but in rare cases, tardive dyskinesia has occurred in people taking low doses. In addition, it’s possible to develop tardive dyskinesia after stopping Vraylar treatment because the drug stays in your body for a long time.

* Sex and gender exist on spectrums. Use of the term “female” in this article refers to sex assigned at birth.

What you can do

Your doctor will monitor you while you’re taking Vraylar to see whether the drug is effective and whether you have any side effects. They’ll try to prescribe the lowest dose that works for you.

While taking Vraylar, watch for symptoms of tardive dyskinesia and talk with your doctor if you develop any of them. They’ll likely want to discuss with you the pros and cons of continuing to take the drug. For some people, Vraylar is the best long-term treatment for their condition, even when tardive dyskinesia occurs. For other people, tardive dyskinesia may be a reason to stop taking Vraylar and switch to a different medication.

Increased risk of death in older adults who have psychosis due to dementia

Vraylar has a boxed warning for an increased risk of death when used for older adults who have psychosis due to dementia. A boxed warning is the strongest warning that the Food and Drug Administration (FDA) requires. Boxed warnings alert patients and doctors about potentially dangerous drug effects.

Older adults with psychosis related to dementia have a higher risk for death when treated with antipsychotic medications, including Vraylar.

What you can do

Vraylar is not FDA-approved for treating psychosis caused by dementia in older adults. If an older adult has psychosis due to dementia and you’re interested in treatments for them, talk with their doctor.

Suicidal thoughts and behaviors

Vraylar has a boxed warning for the risk of suicidal thoughts and behaviors in children and young adults. A boxed warning is the strongest warning that the FDA requires. Boxed warnings alert patients and doctors about potentially dangerous drug effects.

Antidepressants may increase the risk of suicidal thoughts and behaviors in children and young adults. Vraylar is a type of antipsychotic drug. But when Vraylar is used to treat depressive episodes in bipolar I disorder, it may act similarly to antidepressants.

Vraylar is not approved for use in people younger than age 18 years. However, whatever your age, your doctor will typically monitor you while you take drugs such as Vraylar. They’ll watch for changes in thinking, including suicidal thoughts or behaviors.

What you can do

This is especially important when you first start taking the medication and whenever your dose is adjusted. If you or someone else notices any changes, talk with your doctor immediately or get emergency medical attention right away.

Allergic reaction

As with most drugs, Vraylar can cause an allergic reaction in some people. But it’s not clear whether this side effect occurred in clinical studies.

Symptoms can be mild or serious and can include:

  • rash
  • itching
  • flushing (temporary warmth, redness, or deepening of skin color)
  • swelling under your skin, typically in your lips, eyelids, feet, or hands
  • swelling of your mouth, tongue, or throat, which can make it hard to breathe

What you can do

For mild symptoms of an allergic reaction, call your doctor right away. They may recommend ways to ease your symptoms and determine whether you should keep taking Vraylar.
