At 2 to 5 mg, aripiprazole is probably the top augmenting agent for depression, but for serious mental illness we rank it only B tier because it is simply not efficacious enough. Dose it properly for psychosis (start around 15 mg), never promise patients it will not cause weight gain, and do not add it to another antipsychotic, where it takes antipsychotic away.
When we reach for it
It is probably the number one augmenting agent for depression at a low dose: the most studied antipsychotic for MDD augmentation, added on top of another medication, with an evidence sweet spot of 2 to 5 mg. By itself it does not really help bipolar depression.
“It is probably the number one augmenting agent at a low dose for depression, proper depression when added to an antidepressant, but by itself doesn't really help in bipolar depression”

“It is the most studied antipsychotic for MDD augmentation. Again, remember augmentation. So it should be added on top of another medication in general. The evidence sweet spot is the two to five milligrams”
38:01Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026 For treatment-resistant depression, the top-line interventions are ECT, TMS, antipsychotics, lithium, thyroid supplement and the ketamines. Among the antipsychotics, aripiprazole has the best evidence and the biggest effect size.
“The best evidence goes to ECT, TMS, TMS. antipsychotics, particularly aripiprazole has the best evidence and the biggest effect size, lithium, thyroid supplement, and the ketamines, esketamine and ketamine. So those would be our top line interventions”
6:46The Deficit Model in Psychiatry & Difficult to Treat Depression with Dr. Chris Aiken | Episode 18Mar 2025Guest episode In schizophrenia we draw the line at aripiprazole: it still causes weight gain, but less than most, and we do not want to try anything more metabolically heavy unless we really have to.
“So you can see there, I kind of draw the line starting with Abilify. Abilify, while still having his weight gain, reasonably less of the proportion than most people. But you can see I'm pretty aggressive. I do not want to try anything above Abilify unless I really have to”
Choosing Antipsychotics in Schizophrenia: Side-Effects, Maximizing Efficacy, and Finding the Right Medication | Episode 17Feb 2025 There is some theory that it works better in people with a less disturbed dopamine system, meaning earlier in the illness or without much long-term stimulant use.
“keep in mind that there's some theory that for Abilify it may work better in people who have a more non-disturbed dopamine system meaning earlier in the disease course or not too much long-term stimulant use”

Dosing and titration
For depression without psychotic features, do not dose it above 5 mg. It is not worth it.
“Do not dose-abilify above 5 mg if what you are trying to do is trying to treat major depressive disorder without psychotic features. Do not do it. Just don't do it. It's not worth it”
59:08Antidepressant Tier List: Psychiatrists Rank Depression Medications for MDDMay 2026 For psychosis or bipolar disorder, start around 15 mg and no lower than 10. Some people respond to less, but as a partial agonist it leaves about 20 percent of the dopamine receptors it binds unblocked.
“You should probably start around 15 and no lower than 10 milligrams. I've seen people respond with lower, but remember, what does that partial agonist mean? It basically means that about 20% of the dopamine receptors that it is bound to is not blocking”
38:50Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026 Low-dose aripiprazole in an acute phase is not what the trials tested. They started at 15 mg, went up to 30 pretty quickly, and had a benzodiazepine (lorazepam as needed) on board.
“Abilify. Keep in mind that with Abilify, they did minimum 15 and all the way up to 30 to get the antipsychotic response in the original trials. And they gave it benzodiazepine as well”

“Well, first of all, they started at 15 milligrams, and then they easily went up to 30 milligrams pretty quickly. And on top of that, they used benzodiazepine. I believe it was lorazepam as a PRN, and it was basically on board”
40:57The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025 It has a three-day half-life. Steady state takes five half-lives, so about two weeks.
“it's got a three-day half-life. Whenever you're thinking about half-life, that means steady state you have to multiply by five because it takes five half-lives to get there, so steady state takes two weeks”
36:45Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026 We are more likely to dose it in the morning, because for a lot of patients stimulation outweighs sedation.
“Aripiprazole is one of those medications that I'm more likely to dose in the morning because stimulation can outweigh sedation for a lot of patients”
38:27Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026 For a patient who skips several doses a week but still takes it several times a week, do not be afraid of a higher dose: if they were stable on 15 mg in the hospital, give 30 mg and they take it three or four times a week.
“So if you have a patient that skips several of their doses every week but is still taking their medications several times a week, don't be afraid to use a higher dose Abilify. Let's say they're stable on Abilify 15 in the hospital. We'll give them Abilify 30 and they take it three or four times a week”
36:10Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026 Bupropion is a 2D6 inhibitor and can be used to raise the effective dose of aripiprazole, including the long-acting injectable forms.
“2D6 inhibitor, and thus can be used to increase effective dose of your Abilifying antenna and Aristata, which maxes out at a 15 to 20 milligram daily dose”

Side effects and safety
Despite its reputation, we have all seen patients gain a ton of weight on it, and in our experience women are affected significantly worse than men. Do not tell a patient starting it that they will not gain weight because it is on the lower end: you will run into problems and they will not trust you.
“We've all seen patients gain a ton of weight on aripiprazole. I do think women are affected significantly worse than men. Most of the patients that I've seen gain a ton of weight tend to be women”

“It can actually lower antipsychotic induced prolactin because even though it's a partial agonist, it binds first before the other antipsychotics”
37:11Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026
Compared with others
We rank it B tier. We might have put it in A tier years ago, but after trying to use it a lot for its favorable side effect profile, it is simply not efficacious enough.
“I probably would have put it into A tier when I was younger, but having tried to use it a lot because of its favorable side effect profile, it's simply not efficacious enough”
35:26Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026 Brexpiprazole is aripiprazole with the volume turned down a little: slightly less intrinsic activity. It is essentially aripiprazole, but harder to dose because of its smaller milligram increments and way more expensive, so we rank it D tier.
“Brexpiprazole or Rexulti is essentially Abilify, but harder to dose because it comes in smaller milligram increments, in my opinion, and way more expensive”
39:55Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026 Also said in 1 more episode
“It's aripiprazole with the volume turned down a little bit. So it's got a little bit less intrinsic activity than aripiprazole”
40:36Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026
Pitfalls and myths
Do not add it to another antipsychotic, especially haloperidol. It binds so tightly to the dopamine receptor that it counteracts the other drug, so adding low-dose aripiprazole takes antipsychotic away rather than adding more.
“I really hate the practice of adding it to Haldol. You're basically making the medications fight each other because it binds so tightly to dopamine receptor that it essentially counteracts a lot of other antipsychotics”
39:31Antipsychotic Tier List: Ranking the Best and Worst Anti-psychoticsOct 2026 Also said in 1 more episode
“If you add low dose Abilify to another antipsychotic, you're actually not adding more antipsychotic. You're taking antipsychotic away because the Abilify will bind more tightly most of the time and at a low dose will not be acting as an antipsychotic”

- AntipsychoticsIn autism, risperidone and aripiprazole are for unwanted or disruptive behaviors, not quasi-psychotic symptoms or general function. Do not give them to high-functioning people without severe disruptive behaviors.
- CariprazineWe rank it B tier. Like aripiprazole, it is not very effective in the end for mania and psychosis, even if it seems to have a good effect on mood in some people.
- LurasidoneIt has the highest akathisia risk of the antipsychotics, with aripiprazole also up there. The drugs that cause less weight gain tend to be the bad ones for akathisia.
- AkathisiaThe antipsychotics that cause less weight gain tend to be pretty bad for akathisia. Lurasidone is definitely number one and aripiprazole is up there. If lurasidone does not cause horrible akathisia, it is a great medication.
- AntipsychoticsPick weight-sparing medications when possible, knowing the trade is often akathisia. Lurasidone is number one for akathisia and aripiprazole is up there; newer drugs that help mood and spare weight still cause a lot of it, and it is a big reason people cannot take them.
- AnxietyOnline prescriber threads answer a short anxiety post with hundreds of medication tips ('just a touch of aripiprazole') and nobody asking what is going on in the person's life.
- Psychiatric intakeAnswering a brief anxiety post with hundreds of medication tips ("just a touch of Abilify") misses the question: is no one going to ask what is going on in this person's life?
- RisperidoneBecause of prolactin, do not be so gung-ho giving it to female patients. You can get away with adding low-dose aripiprazole to bring prolactin down.
