Medically Reviewed By Elizabeth Scheffel, PharmD

This drug has boxed warnings, the most serious warnings from the Food and Drug Administration (FDA). Boxed warnings alert doctors and patients about drug effects that may be dangerous.

Risk of death in older adults with dementia-related psychosis. Older adults with dementia-related psychosis may have an increased risk of death with antipsychotics. Abilify is an antipsychotic, so it carries this risk. (Psychosis is a mental health condition where you lose touch with reality and may have hallucinations. Dementia is a condition involving memory loss.) Due to this risk, doctors typically will not prescribe Abilify to adults ages 65 years and older with dementia-related psychosis.

Risk of suicidal thoughts and behaviors. Certain medications that treat depression, including Abilify, may increase the risk of suicidal thoughts and behavior in children and adults ages 24 years and younger. For this reason, doctors will monitor anyone taking Abilify for signs of new or worsening depression and suicidal thoughts and behaviors. They may also recommend that close family members of anyone taking Abilify watch for any changes in mood.

For more information about the boxed warnings for Abilify, talk with your doctor or pharmacist.

Abilify: Dosage considerations

Your doctor will consider the following factors when prescribing a dosage of Abilify. These factors include:

  • your age
  • the condition you’re taking Abilify to treat
  • the severity of your condition
  • your weight
  • other medications you take

Your prescribed dosage may also vary based on other medical conditions you have.

Recommended adjustments in dosage

Abilify is broken down in your liver by two enzymes (certain proteins) called CYP2D6 and CYP3A4.

If your CYP2D6 enzyme doesn’t work as well as usual, your body might not be able to break down Abilify like it should. (This condition is referred to as being a “poor metabolizer” of CYP2D6.) In this case, your doctor may prescribe a lower Abilify dosage than typical for you.

Certain medications induce (speed up) or inhibit (slow down) the action of CYP3A4. If you take Abilify with any of these medications, your body could metabolize Abilify differently than usual.

Taking Abilify with CYP3A4 inducers can decrease the amount of Abilify in your body. This means the drug may not work as well as intended. Due to this risk, your doctor will likely increase your dosage if you take one of these medications. Examples of strong CYP3A4 inducers include certain seizure medications, such as carbamazepine (Tegretol). They can also include certain antibiotics, such as rifampin (Rifadin).

Taking Abilify with CYP3A4 or CYP2D6 inhibitors can increase your risk of side effects of Abilify. Due to this risk, your doctor will likely reduce your dosage of Abilify if you take one of these medications.

Examples of strong CYP3A4 inhibitors include certain antibiotics, such as clarithromycin. They can also include antifungal medications, such as ketoconazole. Examples of strong CYP2D6 inhibitors include certain antidepressants, such as fluoxetine (Prozac). They can also include the antiarrhythmic medication quinidine.

Abilify: How to take

Abilify comes as a tablet that you swallow. You’ll take your dose once per day. You may take this dosage with or without food.

Abilify tablets should be swallowed whole. Avoid chewing, crushing, or cutting the tablets.

If it’s difficult for you to swallow tablets, see this article for information on taking this form of medication. Talk with your doctor or pharmacist and ask if they have other suggestions to help you take the medication.


If you find it challenging to read the label on your prescription, tell your doctor or pharmacist. Certain pharmacies provide medication labels with large print or braille. They may also offer labels that contain a scannable code that your smartphone can convert into text to speech. If your pharmacy doesn’t provide these choices, your doctor or pharmacist may be able to recommend a pharmacy that does.

If it’s difficult for you to open medication bottles, ask your pharmacist if they can dispense Abilify in an easy-open container. They also may recommend ways to help make it easier to open the bottles.

Abilify: Missing a dose
