Can't find or afford Abilify? Learn about the best alternatives to Aripiprazole, including Rexulti, Seroquel, Risperdal, and Geodon, and how they compare.
If you've been unable to fill your Abilify (Aripiprazole) prescription — whether because of a supply issue, cost, or side effects — you may be wondering what other medications are available. The good news is that there are several effective alternatives in the same drug class that your doctor may consider.
This guide covers what Abilify is, how it works, and the most common alternatives your prescriber might recommend. Important: Never switch or stop a psychiatric medication on your own. Always work with your doctor to find the right option for you.
Abilify is the brand name for Aripiprazole, an atypical antipsychotic medication. It's one of the most widely prescribed psychiatric drugs in the United States, with more than 7 million prescriptions each year.
Abilify is FDA-approved to treat:
It's available as oral tablets (2 mg to 30 mg), orally disintegrating tablets, oral solution, sublingual film, and long-acting injectable formulations.
Abilify has a unique mechanism of action compared to most antipsychotics. It works as a partial agonist at dopamine D2 receptors, which means it can both boost and reduce dopamine signaling depending on what the brain needs. It also acts on serotonin receptors (5-HT1A and 5-HT2A), helping to stabilize mood and reduce psychotic symptoms.
This "dopamine stabilizer" effect is why Abilify tends to cause less sedation and weight gain than some other antipsychotics — though side effects like akathisia (restlessness), nausea, and insomnia are still common. For a deeper dive, see our post on how Abilify works.
There are several reasons you might need a different medication:
Brexpiprazole, sold as Rexulti, is the closest relative to Abilify. Developed by the same manufacturer (Otsuka), it works through a very similar mechanism — partial agonism at dopamine D2 and serotonin 5-HT1A receptors.
FDA-approved for:
Key differences from Abilify:
Rexulti is a strong option if akathisia on Abilify has been a problem for you.
Quetiapine, sold as Seroquel (immediate-release) and Seroquel XR (extended-release), is another atypical antipsychotic widely used for many of the same conditions.
FDA-approved for:
Key differences from Abilify:
Quetiapine is a good option if insomnia is a major part of your symptoms, since its sedating properties can be therapeutic.
Risperidone, sold as Risperdal, is one of the most established atypical antipsychotics. It's often the first-line choice for children and adolescents with psychosis.
FDA-approved for:
Key differences from Abilify:
Ziprasidone, sold as Geodon, is an atypical antipsychotic with a relatively favorable metabolic profile.
FDA-approved for:
Key differences from Abilify:
Ziprasidone is worth discussing with your doctor if you're concerned about weight gain.
Every patient is different, and the best alternative depends on your specific situation. Here are some factors your doctor will consider:
If you're only considering an alternative because you can't find Aripiprazole at your pharmacy, it's worth trying a few more steps before switching medications. Psychiatric medication changes can cause side effects and adjustment periods, so staying on your current medication is usually preferable if possible.
Abilify is an excellent medication, but it's not the only option. If you need to switch — whether for availability, cost, or side effect reasons — Brexpiprazole, Quetiapine, Risperidone, and Ziprasidone are all proven alternatives that your doctor can help you evaluate.
