Clinical Highlights
Asenapine (brand Saphris sublingual tablets; Secuado transdermal system) is a second-generation (atypical) antipsychotic formulated to avoid extensive first-pass metabolism and provide rapid absorption. This profile focuses on its use in schizophrenia and bipolar I disorder; U.S. approvals include schizophrenia in adults (sublingual 2009, transdermal 2019) and acute manic or mixed episodes in adults and pediatric patients ≥10 years, as monotherapy or adjunct to lithium/valproate.

- Sublingual tablets can cause oral numbness and require avoiding food or drink for 10 minutes after dosing. The patch can be helpful when swallowing is unreliable or when a patient declines LAIs, but cost and skin reactions can be limiting.
- The compare view to benchmark sedation, metabolic, and formulation considerations, and review asenapine-focused evidence alongside resources in the schizophrenia hub and bipolar disorder hub when coordinating long-term care.
- Schizophrenia (sublingual tablet) (FDA 2009)
- Schizophrenia (transdermal patch) (FDA 2019)
- Acute manic/mixed episodes in bipolar I disorder (adults) (FDA 2009)
Dosing & Formulations
Sublingual tablets: 2.5 mg, 5 mg, 10 mg (taken twice daily; must dissolve under the tongue). Transdermal patch (Secuado): 3.8 mg/24 h, 5.7 mg/24 h, 7.6 mg/24 h applied once daily to rotating sites.

- Schizophrenia (adults): initiate 5 mg sublingually twice daily; increase to 10 mg twice daily based on response; patch initiation 3.8 mg/24 h once daily with titration to 5.7–7.6 mg/24 h.
- Bipolar I acute manic/mixed episodes (adults): start 10 mg sublingually twice daily on day 1, then 5–10 mg twice daily; adjunct dosing with lithium/valproate mirrors monotherapy.
- Pediatric bipolar I (≥10 years): initiate 2.5 mg twice daily; titrate by 2.5–5 mg to a maximum 10 mg twice daily.
- Therapeutic drug monitoring is not routinely recommended; serum levels have not correlated with efficacy.
Monitoring & Risks
Boxed warning: Increased mortality in elderly patients with dementia-related psychosis (antipsychotic class warning). Somnolence/sedation: Reported in ~13–24% of patients; leading reason for discontinuation.
Read more
- Akathisia/restlessness: Occurs in ~10–12%, often within first 3 weeks.
- Oral hypoesthesia/dysgeusia: Unique to sublingual formulation (7–15%); typically transient.
- Weight gain: ≥7% weight gain in roughly 7–9% over 3–6 months.
- Dizziness/orthostatic hypotension: Around 10%, more common during initial titration.
Drug Interactions
Strong CYP1A2 inhibitors (e.g., fluvoxamine, ciprofloxacin) raise concentrations—monitor for sedation and EPS; dose reduction may be needed. CYP1A2 inducers, including cigarette smoking and carbamazepine, lower exposure—monitor efficacy and adjust dose within labeling limits.

- Potent enzyme inducers affecting UGT pathways (e.g., rifampin) can reduce levels; consider alternatives or monitor closely.
- Additive CNS depression with benzodiazepines, opioids, alcohol, or antihistamines.
- May antagonize effects of levodopa and dopamine agonists; avoid coadministration in Parkinson’s disease when possible.
Practice Notes
Store sublingual tablets in original blister packaging; handle with dry hands and allow to dissolve fully under the tongue. Oral numbness usually resolves within an hour; severe dysesthesia, swelling, or signs of hypersensitivity warrant urgent evaluation.

- Rotate patch sites daily (upper arm, abdomen, hip, back) and inspect for erythema; mild application-site reactions occur in <10%.
- Weight, fasting lipids, and glucose are typically monitored periodically despite relatively modest metabolic liability.
- Changes in smoking status can alter plasma exposure through CYP1A2 induction or cessation; dosing may need reassessment when tobacco use changes.
- Consider baseline and follow-up ECGs in patients with cardiac risk factors or concomitant QT-prolonging regimens.
- Share printable counseling sheets from the asenapine print view, compare alternatives via the contrast table, and align relapse-prevention plans with the schizophrenia hub and bipolar disorder hub.
