Asenapine (Saphris, Secuado)

FDA Approved 2009

Clinical summary for Asenapine (Saphris, Secuado): Asenapine (Saphris, Secuado) is a newer antipsychotic used for schizophrenia and bipolar I disorder. It’s unusual in that you either let the tablet fully dissolve under your tongue or wear it as a skin patch—if you swallow the tablet like a regular pill, the medicine barely gets absorbed. Many people notice drowsiness, mouth numbness or bad taste, and some weight gain. Like other antipsychotics, it can affect blood sugar, cholesterol, and movement, so regular checkups and labs are important. It is not approved for dementia-related behavior in older adults because it can increase the risk of death and stroke in that group.

What It’s Used For

Asenapine is an atypical antipsychotic for psychosis and mood episodes, especially when a fast-dissolving under-the-tongue tablet or skin patch is helpful.

Primary Indications

Schizophrenia (adults): Hallucinations, delusions, disorganized thinking, and negative symptoms.Bipolar I disorder – acute manic or mixed episodes (adults): Elevated or irritable mood, decreased need for sleep, increased activity, racing thoughts.Bipolar I disorder – acute manic or mixed episodes in children and adolescents ≥10 years (sublingual only).Maintenance treatment of bipolar I disorder in adults as monotherapy after stabilization on asenapine.

Off-Label Uses

Schizoaffective disorder (antipsychotic component of treatment plan)Severe acute agitation or aggression associated with psychotic or bipolar disorders (sublingual as a rapid oral option)Adjunctive use when other atypical antipsychotics are partially effective but limited by metabolic side effects

What People Commonly Notice

Experiences vary, but these are typical early and ongoing effects people report on asenapine:

Early Sedation & Slowing

"I felt more tired and sleepy, especially in the first week."

How Fast It Works

Some effects show up quickly, while full benefit takes longer.

15–30 minutes

Some calming of agitation may be noticeable after a sublingual dose.

Days 3–7

Many people with mania or mixed episodes start to feel more stable.

1–2 weeks

Early antipsychotic effects in schizophrenia (less intense hallucinations, slightly clearer thinking).

4–6 weeks

Full/steady antipsychotic response is typically evaluated.

24 hours

Each Secuado patch is designed to deliver medicine steadily over 24 hours.

How Well It Works

Symptom Improvement vs Placebo

Modest-to-moderate effect size
vs Better than placebo in acute schizophrenia and bipolar I mania trials
Across randomized clinical trials, asenapine has shown meaningful improvement in psychotic and manic symptoms compared with placebo. It is generally considered similar in overall antipsychotic effectiveness to other second-generation antipsychotics, with modest-to-moderate effect sizes. Its main advantages are flexible routes (sublingual/patch) and relatively lower risk of major weight gain and metabolic changes compared with some agents (eg, olanzapine), but it may cause more sedation and oral numbness.

Critical Safety Information

Critical Safety Information

Not approved in older adults with dementia-related psychosis due to increased risk of death and stroke.
  • →Do not use this medication to treat dementia-related behavior in older adults unless a specialist specifically recommends it.
  • →Tell your doctor right away if you faint, feel your heart racing or skipping, or have a family history of sudden cardiac death or long QT.
  • →Watch for fever, severe muscle stiffness, confusion, or very fast heartbeat—these may be signs of a rare emergency reaction (NMS).
  • →Report new or unusual movements of your face, lips, tongue, or body immediately.
  • →Rise slowly from sitting or lying positions to reduce dizziness and risk of falls.
  • →Tell your doctor about all other medications, especially those that affect heart rhythm or cause sedation (sleepiness).

Side Effects

Most common: drowsiness, mouth numbness and bad taste (sublingual), weight gain, and restlessness or stiffness. Serious but less common risks include abnormal heart rhythms, severe allergic reactions, blood problems, and movement disorders.

Common Things People Notice

  • Sleepiness or feeling slowed down
  • Numbness or tingling in the mouth and a bitter taste after the sublingual tablet
  • Weight gain and increased appetite
  • Restlessness (akathisia), muscle stiffness, or shaking
  • Constipation and stomach discomfort
  • Skin redness or itching where the patch is applied

Common Side Effects

Very common (up to ~50% in children, 3–26% in adults)
Drowsiness / Somnolence— You may feel more sleepy or sluggish, especially when starting or when doses are increased. Dosing at night (if appropriate) and avoiding other sedating drugs can help.
5–30%
Oral hypoesthesia & taste changes (sublingual tablets)— Numbness or tingling under the tongue and a bitter or unusual taste usually start soon after the tablet dissolves and fade over 30–60 minutes.
1–22% (dose and duration dependent)
Weight gain & increased appetite— Weight gain can occur, though on average it’s less than with some antipsychotics (like olanzapine). Nutrition, exercise, and regular weight checks are important.
Adults ~8–15%; lower in children with recommended dosing
Extrapyramidal symptoms (EPS: stiffness, tremor, akathisia)— You might feel restless, stiff, or shaky. Tell your prescriber—dose adjustments or other medications can help.
Several percent; risk varies by individual
Metabolic changes (glucose, lipids, cholesterol)— Blood sugar and cholesterol may go up. Regular lab monitoring and lifestyle changes can reduce risk.
Erythema or itching in ~10–15%
Application-site reactions (patch)— Redness, itching, or mild burning at the patch site is common. Rotating sites and avoiding heat can help.

⚠️ Serious Side Effects

  • Neuroleptic Malignant Syndrome (NMS): high fever, rigid muscles, confusion, unstable blood pressure or heart rate—medical emergency.
  • Tardive dyskinesia: involuntary movements of face, lips, tongue, or body that may be permanent.
  • QT prolongation and serious arrhythmias: can cause fainting or sudden cardiac events in high-risk patients.
  • Severe allergic reactions: anaphylaxis, angioedema, swollen tongue, difficulty breathing or swallowing.
  • Leukopenia, neutropenia, agranulocytosis: very low white blood cell counts, increasing infection risk.
  • Hyperglycemia / diabetes and dyslipidemia: dangerously high blood sugar or lipids in susceptible individuals.
  • Seizures: especially in patients with prior seizure history or other risk factors.

Important Drug Interactions

Asenapine is metabolized mainly by CYP1A2 and can affect or be affected by other sedating or QT-prolonging drugs.

With: Strong CYP1A2 inhibitors (eg, fluvoxamine, ciprofloxacin)

Risk: May significantly increase asenapine blood levels, raising risk of side effects (sedation, EPS, QT prolongation).

Action: Use with caution. Consider dose reduction of asenapine and close monitoring.

With: CNS depressants (eg, benzodiazepines, opioids, alcohol, sedating antihistamines, sleep medications)

Risk: Additive sedation, dizziness, falls, respiratory depression.

Action: Use the lowest effective doses, avoid alcohol, and monitor closely. In many cases prefer non-sedating alternatives.

With: Other QT-prolonging medications (eg, certain antiarrhythmics, macrolide antibiotics, methadone, some antidepressants)

Risk: Increased risk of clinically significant QT prolongation and arrhythmias.

Action: Avoid if possible. If combination is unavoidable, obtain baseline and follow-up ECGs and correct electrolytes.

With: Dopamine agonists (eg, levodopa, pramipexole) for Parkinson’s disease

Risk: Asenapine can blunt the effects of dopamine agonists, worsening Parkinsonian symptoms.

Action: Generally avoid this combination. If needed, use lowest effective doses and monitor motor symptoms closely.

With: Other antipsychotics or drugs causing EPS (eg, metoclopramide)

Risk: Increased risk of extrapyramidal symptoms and tardive dyskinesia.

Action: Avoid chronic combination when possible. If combined, monitor closely for movement side effects.

With: Antidiabetic agents

Risk: Asenapine may worsen glucose control, reducing the effectiveness of antidiabetic medications.

Action: Monitor blood glucose more frequently and adjust diabetes therapy as needed.

Stopping or Switching Safely

Asenapine is not physically addictive in the way benzodiazepines or opioids are, but stopping suddenly can still cause symptom rebound and withdrawal-like effects.

Key Points

  • Do not stop abruptly unless there is a serious side effect (eg, NMS, severe allergic reaction) and you are under medical supervision.
  • Typical taper: decrease dose gradually over weeks to months (eg, 10–25% dose reduction every 1–2 weeks), especially for long-term use.
  • Watch for return or worsening of psychosis, mania, or anxiety as doses decrease. Taper more slowly if symptoms reappear.
  • When switching to another antipsychotic, many clinicians use cross-titration (gradually decreasing asenapine while increasing the new medication).
  • Monitor sleep, mood, and psychotic symptoms closely during the tapering process. Involve family or supports to help watch for early warning signs.

Dosing Information

Adult Dosing

schizophrenia initial: Sublingual: 5 mg twice daily (BID). Some clinicians may start lower (eg, 5 mg/day divided) in very sensitive or first-episode patients.

schizophrenia titration: Increase to 10 mg BID (20 mg/day total) based on response and tolerability, usually after at least several days to a week.

schizophrenia max: 20 mg/day (10 mg BID) for sublingual tablets.

schizophrenia patch: Start with Secuado 3.8 mg/24 hours patch once daily. May increase in weekly steps to 5.7 mg/24 hours or 7.6 mg/24 hours based on response and tolerability.

bipolar mania initial: Sublingual: 5–10 mg BID as monotherapy; 5 mg BID when used with lithium or valproate.

bipolar mania titration: May increase to 10 mg BID (max) as tolerated.

bipolar mania max: 10 mg BID (20 mg/day).

hepatic: Mild–moderate (Child-Pugh A or B): no formal adjustment required but consider lower starting dose and slower titration. Severe (Child-Pugh C): CONTRAINDICATED.

renal: No dosage adjustment generally required in renal impairment.

elderly: Use lower end of dosing range; titrate slowly and monitor closely for orthostasis, sedation, and falls.

Simple Explanation

For most adults, asenapine is taken as a small tablet that melts under the tongue twice a day or as a once-daily patch. Doses are adjusted slowly based on symptom improvement and side effects. You should not swallow the sublingual tablet, and you should not cut the patch.

Pregnancy, Breastfeeding & Special Groups

Asenapine is part of the second-generation antipsychotic class; decisions in pregnancy and special populations should balance relapse risk against medication risks.

👶Pregnancy

Studies of atypical antipsychotics as a group have not shown a large increase in major birth defects, but data for asenapine specifically are limited. Use during the third trimester is associated with risk of extrapyramidal and/or withdrawal symptoms in the newborn (e.g., agitation, abnormal muscle tone, feeding difficulties, respiratory distress). Stopping effective antipsychotic treatment can markedly increase the risk of relapse, which itself can harm pregnancy. Use the lowest effective dose, avoid polypharmacy when possible, and manage as part of a shared decision-making process with psychiatry and obstetrics.

🤱Breastfeeding

It is not clearly known whether asenapine is present in human breast milk, but similar medications can be excreted and may cause sedation, poor feeding, or abnormal movements in infants. If used while breastfeeding, use the lowest effective dose, avoid additional sedating medications, and monitor the infant for sleepiness, feeding problems, or unusual movements. Discuss risks and benefits with your prescriber.

👧Children & Adolescents (Under 18)

Sublingual asenapine is approved for acute manic or mixed episodes in bipolar I disorder for ages 10–17. Children and adolescents may be more sensitive to weight gain, metabolic changes, and movement symptoms. Growth, weight, metabolic parameters, and movement should be monitored regularly.

👴Older Adults (65+)

Older adults are at higher risk of orthostatic hypotension, sedation, falls, stroke, and mortality when taking antipsychotics—especially those with dementia-related psychosis. Use only when clearly indicated, at the lowest effective dose, and reassess frequently.

🔬Liver Impairment

Severe hepatic impairment (Child-Pugh C) leads to ~7-fold increase in exposure and is a contraindication. Mild to moderate impairment requires careful dosing and monitoring.

💧Kidney Impairment

No formal adjustment is typically required, but comorbidities and polypharmacy should be considered.

Clinical Monitoring

  • Vital signs: blood pressure (including orthostatic), heart rate, temperature at baseline and periodically, especially during early treatment and dose changes.
  • Weight, BMI, and waist circumference: at baseline, 8 and 12 weeks after starting or changing dose, then quarterly.
  • Metabolic labs: fasting glucose/HbA1c and lipid panel at baseline, ~4 months after starting, and at least annually (more often if abnormal or high-risk).
  • CBC: as clinically indicated, especially in patients with prior low white blood cell counts or history of drug-induced leukopenia/neutropenia.
  • Extrapyramidal symptoms (EPS): at each visit; use a formal rating scale (eg, SAS, BARS) at least annually or more often if high risk.
  • Tardive dyskinesia: assess at every visit; use a standardized scale (eg, AIMS) at least annually or every 6 months in high-risk patients.
  • Mental status and symptom severity: track psychosis, mood, agitation, suicidality with standardized scales where appropriate.
  • Fall risk: assess at each visit, especially in older adults (gait, balance, prior falls, sedating co-medications).
  • Prolactin-related symptoms: ask about menstrual changes, sexual dysfunction, galactorrhea, or breast changes; check prolactin level if symptoms arise.
  • Liver function: baseline and periodically in patients with known or suspected hepatic disease.
  • ECG: consider baseline and follow-up in patients with cardiac disease, electrolyte abnormalities, or on QT-prolonging medications.

Available Formulations

  • Sublingual Tablets (Saphris / generics): 2.5 mg, 5 mg, 10 mg. Place under tongue and allow to completely dissolve; do not chew, crush, or swallow whole.
  • Transdermal Patch (Secuado): 3.8 mg/24 hours, 5.7 mg/24 hours, 7.6 mg/24 hours. Apply once daily to upper arm, upper back, abdomen, or hip and change every 24 hours.

How It Works

Asenapine is a multi-receptor atypical antipsychotic. It blocks dopamine D2 receptors, which reduces positive psychotic symptoms like hallucinations and delusions, and blocks multiple serotonin receptors (especially 5-HT2A), which may improve mood and negative symptoms and reduce the risk of some movement side effects compared with older antipsychotics. It also blocks histamine H1 and alpha-adrenergic receptors, contributing to sedation, weight gain, and orthostatic hypotension. It has minimal activity at muscarinic receptors, so classic anticholinergic side effects (eg, dry mouth, constipation, blurred vision) are usually milder than with some other antipsychotics.

Place in Treatment Algorithm

Asenapine is one of several second-generation antipsychotics available for schizophrenia and bipolar I mania. It is generally not the first atypical tried for most people, but it can be a strong option when:

- A sublingual route is preferred (eg, difficulty swallowing, desire for fast onset, or concern about cheek-pocketing tablets).
- A once-daily patch is attractive for adherence or routine reasons.
- Patients have experienced substantial metabolic problems (eg, with olanzapine) and can tolerate some sedation and oral side effects.

Choice among antipsychotics should consider prior treatment response, side-effect profile, comorbidities (eg, metabolic syndrome, cardiac disease), patient preference, and route of administration.

Frequently Asked Questions

What is asenapine used for?

Asenapine (Saphris, Secuado) is used to treat schizophrenia in adults and acute manic or mixed episodes of bipolar I disorder in adults and in children aged 10 and older (sublingual only). In adults, the sublingual form can also be used as maintenance treatment once symptoms are stabilized.

How do I take the Saphris sublingual tablet correctly?

With Saphris, you place the tablet under your tongue and let it fully dissolve. Do not chew, crush, or swallow it. Avoid eating or drinking for at least 10 minutes afterward, or you may absorb less medication and it may not work as well.

What is the difference between Saphris and Secuado?

Saphris is the sublingual tablet that dissolves under your tongue and is taken twice a day. Secuado is a skin patch you apply once daily. Both deliver asenapine, but the patch is only approved for adults with schizophrenia and may be easier for people who struggle with pills or remembering multiple doses.

How long does asenapine take to work?

Some people notice reduced agitation or calming within an hour of a sublingual dose. For manic episodes, improvement often appears within a few days, with further gains over 1–3 weeks. For schizophrenia, it may take 1–2 weeks for early improvement and 4–6 weeks to judge full response.

Does asenapine cause weight gain?

Yes, weight gain can occur on asenapine, but it is generally less than with some antipsychotics like olanzapine. People may also have increased appetite. Your weight, blood sugar, and cholesterol should be checked regularly so problems can be caught early.

What are the most common side effects?

The most common side effects are sleepiness, dizziness, mouth numbness and bad taste (with the sublingual tablets), weight gain, restlessness or stiffness, and mild stomach issues like constipation. The patch can cause skin redness or itching at the application site.

Can I drink alcohol while taking asenapine?

It’s best to avoid alcohol while on asenapine. Both asenapine and alcohol can make you sleepy, affect coordination, and increase the risk of falls and accidents. Combining them can worsen side effects and make it harder to judge your level of impairment.

Is asenapine safe in older adults with dementia?

No. Like other antipsychotics, asenapine carries a boxed warning about increased risk of death in older adults with dementia-related psychosis. It is not approved for this use and is generally avoided unless a specialist determines it is absolutely necessary.

What heart risks should I know about?

Asenapine can prolong the QT interval on an ECG, which in rare cases can lead to serious heart rhythm problems. Tell your doctor if you have heart disease, a history of fainting, or a family history of sudden cardiac death. Avoid combining asenapine with other medications that strongly prolong the QT interval unless your prescriber is carefully monitoring you.

Can asenapine be used in children?

The sublingual form (Saphris) is FDA-approved for acute manic or mixed episodes of bipolar I disorder in children and adolescents aged 10–17. It is not approved for schizophrenia in children. When used in youth, careful monitoring of growth, weight, metabolic labs, and movement symptoms is essential.

What if I miss a dose?

If you miss a sublingual dose and it’s not too close to your next scheduled dose, take it when you remember. If it’s almost time for the next dose, skip the missed dose—do not double up. For the patch, apply a new patch as soon as you remember after removing the old one; if it’s close to your next scheduled change time, wait and apply at the normal time. When in doubt, ask your prescriber or pharmacist.

How do I safely stop asenapine?

Do not stop asenapine suddenly on your own unless you’re having a severe reaction and have been told to stop. Your doctor will usually reduce the dose gradually over weeks to months to watch for relapse of symptoms and any withdrawal-like effects such as insomnia, anxiety, or mood changes.
