Decision GuideWhen to pick each / when to consider an alternative
Aripiprazole
Consider when
- Hyperprolactinemia concern — only SGA that lowers prolactin; can reverse galactorrhea/amenorrhea from prior antipsychotic
- Metabolic-sparing antipsychotic needed — lowest BMI change (+0.22 kg/m²) and near-placebo glucose/lipid effects in Huhn 2019 NMA
- Pediatric autism irritability (6–17) or Tourette disorder — FDA-approved both; one of only two SGAs with pediatric autism indication
- LAI for long-term adherence — monthly Maintena or 2-monthly Asimtufii; broadest LAI option set among partial agonists
- +1 more
Consider an alternative when
- History of pathological gambling, hypersexuality, or impulse-control disorder — partial D2 agonism carries unique compulsive behavior risk
- Akathisia is poorly tolerated — Huhn 2019 RR ~1.95 (mid-to-high among SGAs); akathisia is leading discontinuation cause
- Restlessness, insomnia, or anxiety worsens with activation — partial-agonist activation profile worse than quetiapine/olanzapine
- Severe acute psychosis requiring rapid sedation — partial agonist may have slower onset; olanzapine IM or haloperidol IM preferred
- +1 more
Risperidone
Consider when
- Pediatric autism irritability (5–16 years) — one of only two SGAs with FDA approval; most extensive pediatric data in autism
- Generic access and broad formulary coverage needed — well-established with extensive long-term outcome data
- LAI for non-adherent patient — biweekly Risperdal Consta; SQ Perseris monthly; established LAI track record
- Prolactin monitoring feasible — therapeutic window 28–112 ng/mL enables plasma-level-guided dosing
- +1 more
Consider an alternative when
- Hyperprolactinemia concern — class-near-top prolactin elevation; galactorrhea, amenorrhea, sexual dysfunction, osteoporosis risk
- Elderly patient with dementia — boxed warning for cerebrovascular events; risperidone specifically studied and flagged
- EPS-vulnerable patient — dose-dependent EPS; parkinsonism and TD risk higher than most newer SGAs
- Cardiometabolic risk patient — second-tier weight gain (~2 kg short-term); worse metabolic profile than aripiprazole/ziprasidone
- +1 more
Paliperidone
Consider when
- Hepatic impairment — 80% renal clearance minimizes hepatic metabolism; no dose adjustment for hepatic impairment
- CYP drug interaction burden is high — avoids CYP2D6/3A4 pathways that complicate risperidone, aripiprazole, and others
- Long-acting injection for non-adherence — three LAI formulations: monthly (Sustenna), 3-monthly (Trinza), 6-monthly (Invega Hafyera)
- Schizoaffective disorder — FDA-approved indication distinct from risperidone; broadest psychotic disorder coverage with LAI
- +1 more
Consider an alternative when
- Hyperprolactinemia concern — class-top prolactin elevation among SGAs; galactorrhea, amenorrhea, osteoporosis, sexual dysfunction
- GI structural narrowing (Crohn's, diverticular disease) — osmotic ER tablet shell may cause obstruction; ghost tablets in stool
- Severe renal impairment — primarily renally cleared; CrCl <50 mL/min requires dose reduction; not recommended CrCl <10
- Cost or formulary constraint — brand-only ER and LAI formulations at significant premium over generic risperidone
- +1 more
Lurasidone
Consider when
- Metabolic risk prohibits other SGAs — lowest glucose P-score (0.09) in Huhn NMA; favorable weight and lipid profile
- Bipolar depression (mono or adjunct) — FDA-approved for both monotherapy and adjunct to lithium/valproate in bipolar I depression
- QTc prolongation risk — negative QTc point estimate (−1.18 ms Leucht); among safest SGAs for cardiac patients
- Prolactin-sensitive patient — low transient prolactin elevation; favorable vs risperidone/paliperidone
- +1 more
Consider an alternative when
- Inconsistent food intake — must take with ≥350 kcal meal; bioavailability ~3× lower fasting; adherence barrier
- Akathisia is a top priority — highest akathisia RR among SGAs in Huhn 2019 (RR 3.93); leading tolerability concern
- Severe nausea or GI sensitivity — nausea 10% vs 5% placebo; rates rise with dose; may limit titration
- On strong CYP3A4 inhibitor or inducer — contraindicated with strong inhibitors (ketoconazole); dose limits with moderate inhibitors
- +1 more
