Antipsychotics with the lowest EPS risk
Which antipsychotics cause the least extrapyramidal symptoms (EPS): akathisia, parkinsonism, dystonia, tardive dyskinesia. Clozapine, quetiapine, and the newest drugs (Cobenfy, lumateperone) rank lowest.
Ranking
Zero to minimal EPS risk (mechanistically):
- Cobenfy (xanomeline-trospium): no D2 blockade, no EPS by mechanism
Very low EPS:
- Clozapine: lowest EPS among D2-blocking antipsychotics; used specifically for tardive dyskinesia patients
- Quetiapine (Seroquel): dose-related, low at typical doses
- Lumateperone (Caplyta): novel mechanism, minimal EPS in trials
Low EPS:
- Olanzapine (Zyprexa): modest EPS at usual doses; more at higher doses
- Aripiprazole (Abilify): partial agonist; akathisia is main EPS concern
Moderate EPS:
- Brexpiprazole (Rexulti): partial agonist; akathisia possible
- Cariprazine (Vraylar): partial agonist; akathisia notable
- Lurasidone (Latuda): dose-related
- Ziprasidone (Geodon): dose-related
- Iloperidone (Fanapt): relatively low but present
Higher EPS:
- Risperidone (Risperdal): dose-related; EPS at higher doses common
- Paliperidone (Invega): similar to risperidone
Highest EPS (first-generation):
- Trifluoperazine, thiothixene, fluphenazine: high-potency, high EPS
- Haloperidol (Haldol): high-potency, high EPS
- Perphenazine (Trilafon): moderate potency
- Chlorpromazine (Thorazine), thioridazine: low-potency, but still substantial EPS
Types of EPS explained
Akathisia: subjective restlessness with observable motor agitation. See akathisia page. Most common EPS. Often misdiagnosed as anxiety.
Drug-induced parkinsonism: bradykinesia, rigidity, resting tremor. Onset days to weeks. Reversible with drug change but can persist months.
Acute dystonia: sustained muscle contractions, most common in young men, first days of treatment. Treated with anticholinergics (benztropine, diphenhydramine).
Tardive dyskinesia (TD): choreoathetoid movements from prolonged exposure. Can be irreversible. See TD page.
When EPS profile drives drug choice
Prior EPS or TD: Cobenfy, clozapine, or quetiapine as strong preferences.
Parkinson's disease: clozapine at low dose or pimavanserin. Avoid drugs with significant D2 blockade.
Older adults: lower-EPS drugs (Cobenfy, aripiprazole at low dose, brexpiprazole, cariprazine, quetiapine at low dose).
Younger male: avoid haloperidol, fluphenazine, risperidone at high doses (highest acute dystonia risk).
Patient priority is preserving movement function: newer, non-D2 or partial-agonist drugs favored.
When EPS trade-off is accepted
Treatment-resistant schizophrenia: clozapine chosen for efficacy even given metabolic burden; EPS is low anyway.
Adequate D2 blockade needed for acute psychosis: risperidone or haloperidol may be chosen despite EPS risk if faster onset or specific efficacy is needed. Anticholinergic co-treatment sometimes added.
LAI treatment: long-acting injectables carry EPS risk of the parent drug. Aripiprazole LAIs have lowest EPS.
Common questions
What is the antipsychotic with the least EPS? Cobenfy (xanomeline-trospium) has no EPS by mechanism because it does not block D2 receptors. Clozapine has the lowest EPS among D2-blocking antipsychotics. See our Cobenfy state of practice.
Does aripiprazole cause akathisia? Yes, at meaningful rates especially at initiation. Aripiprazole activation and akathisia are notable enough that some patients cannot tolerate it despite the drug's other advantages.
Is quetiapine EPS-free? Very low at typical doses. Some EPS at high doses (400+ mg). Effectively EPS-free at low doses used for sleep or augmentation.
Which antipsychotic is safest for Parkinson's disease? Clozapine at low dose (12.5 to 50 mg) has best evidence but requires ANC monitoring. Pimavanserin has FDA approval for Parkinson's psychosis. Quetiapine at low dose is used off-label.
Should I take an anticholinergic (benztropine) prophylactically? Usually not. Benztropine and other anticholinergics prevent acute dystonia but add anticholinergic burden. Reserved for patients with acute dystonia history or high-EPS-risk drug initiation.
Does TD only happen with first-generation antipsychotics? No. Second-generation drugs also cause TD, at lower rates (1 to 3 percent per year vs 5 percent per year for first-generation). Cumulative exposure matters more than drug class.

Managing a medication needs a prescriber
Any psychiatric medication has to be started and adjusted by a clinician who can follow you over time. If you don't have a prescriber, our guides section explains the options, including in-person care and telepsychiatry, and how to choose between them.
