Quetiapine is a modern atypical antipsychotic widely used across the United States to help manage schizophrenia and bipolar I disorder, and as add-on therapy for treatment-resistant major depressive disorder in adults. It became available in the U.S. in the late 1990s and is now offered in both brand-name and generic formulations. Today, Americans can access quetiapine as immediate-release (IR) tablets taken once or twice daily, and as extended-release (XR) tablets designed for once-daily dosing, typically in the evening. The most common strengths include 25 mg, 50 mg, 100 mg, 200 mg, 300 mg, and 400 mg.

While quetiapine is a prescription medication in the USA, eligible adults may obtain it through licensed community pharmacies, mail-order services, or telehealth platforms that operate in compliance with federal and state regulations. Generic quetiapine has made treatment more affordable for many patients. If your clinician determines that quetiapine is appropriate for your condition, you can explore IR or XR versions depending on your diagnosis, dosing convenience, and response to therapy. As always, decisions about dose and formulation should be made with your prescriber, who will weigh clinical benefits against potential risks, including metabolic effects, sedation, and cardiovascular considerations.

Quetiapine price and typical U.S. cost factors

In the United States, the price you pay for quetiapine depends on several factors: whether you use IR or XR tablets, the tablet strength, the total daily dose prescribed, your pharmacy’s cash price, and your insurance coverage or discount program. Generic quetiapine is generally much less expensive than brand-name Seroquel or Seroquel XR. Many pharmacies offer competitive cash prices, and discount cards or manufacturer savings for brand versions may lower your out-of-pocket expense. Mail-order and 90-day fills can further reduce per-tablet costs for maintenance therapy.

Because pharmacy pricing varies by location and insurance networks, consider the following tips:

• Ask your prescriber whether IR or XR is preferred for your diagnosis and if either formulation could reduce your copay.
• Compare prices at multiple local and mail-order pharmacies using reputable U.S. tools and discount programs.
• Discuss tablet splitting only if appropriate for the formulation and strength—note that XR tablets must not be split, crushed, or chewed.
• Check whether a 90-day supply is permitted by your plan, which may lower your per-day cost.

Important: Prices shown by any pharmacy or website are estimates and can change without notice. The final price is determined at the point of sale and may be influenced by your insurance benefits, copay tier, deductible status, and applicable rebates or coupons.

Where can I buy quetiapine in the USA?

If you’ve been prescribed quetiapine by a licensed U.S. healthcare professional, you can fill your prescription at most chain and independent pharmacies, as well as through many accredited online pharmacies and telehealth services operating within the United States. Look for state-licensed providers and, where applicable, services accredited by the National Association of Boards of Pharmacy. Never purchase prescription antipsychotics from unverified sources. In the USA, quetiapine cannot be legally obtained without a valid prescription.

Our platform connects patients with reputable pharmacy partners that focus on prompt delivery, transparent pricing, and patient support. If you are new to therapy, consider a telehealth evaluation to determine whether quetiapine is appropriate, to discuss potential risks and benefits, and to choose between IR and XR formulations based on your individual needs and medical history.

For individuals who have difficulty visiting a physical pharmacy or prefer the convenience of home delivery, online dispensing from licensed U.S. providers may be an efficient option. Ensure that any service you use requests a valid prescription, offers pharmacist counseling, and provides clear information on shipping, returns, and privacy.

Quetiapine in the United States

Quetiapine has a well-established role in the U.S. for managing certain psychiatric conditions. It is FDA-approved for adult schizophrenia, bipolar I mania (alone or in combination with lithium or valproate), bipolar depression, and adjunctive treatment of major depressive disorder. Pediatric approvals are more limited and generally apply to specific ages and indications; speak with a specialist for pediatric use. Because this medication can cause sedation, orthostatic hypotension, and metabolic changes, prescribers often schedule regular follow-up to evaluate response, tolerability, and necessary lab monitoring.

What is quetiapine?

Quetiapine is an atypical antipsychotic medication. It influences multiple neurotransmitter systems in the brain, including serotonin and dopamine pathways. Its active metabolite, norquetiapine, contributes to antidepressant and anxiolytic effects through additional receptor activity and norepinephrine transporter inhibition. In practice, clinicians select quetiapine because of its broad utility across schizophrenia and bipolar I disorder and its accepted role as add-on therapy for major depressive disorder in adults who have not responded adequately to standard antidepressant treatment alone.

Quetiapine is available in immediate-release tablets, which may be taken once or twice daily, and extended-release tablets, typically dosed once nightly. The choice between IR and XR can depend on lifestyle, side-effect profile, insurance, and clinical goals. Doses are individualized and often titrated upward over several days to minimize side effects such as excessive sedation, dizziness, or orthostatic hypotension.

Because this medicine has central nervous system effects, it must be used under medical supervision. Patients should be counseled on safety precautions, potential interactions (especially with CYP3A4 inhibitors or inducers), and the importance of ongoing monitoring for weight, glucose, and lipid changes.

Quetiapine for schizophrenia

Schizophrenia is a chronic psychiatric disorder characterized by symptoms such as delusions, hallucinations, disorganized thinking, and negative symptoms like social withdrawal and diminished motivation. Quetiapine can reduce positive symptoms and may help with mood and sleep disturbance commonly seen in schizophrenia. Treatment goals include symptom reduction, relapse prevention, improved function, and enhanced quality of life.

Initial titration aims to reach an effective dose while minimizing side effects. Your prescriber may choose either IR or XR tablets based on adherence considerations and your daily routine. Consistent daily dosing, regular follow-up, and collaborative care with mental health professionals support better long-term outcomes.

Therapy is individualized: some patients respond well at lower doses, while others require higher dosing within the FDA-labeled range. If you experience new or worsening symptoms, contact your care team promptly. Never stop quetiapine on your own, as abrupt discontinuation can lead to symptom recurrence or withdrawal-like effects such as insomnia and irritability.

Why quetiapine may be chosen

Clinicians may select quetiapine for patients who benefit from its sedative properties at bedtime, those who have not responded adequately to other antipsychotics, or individuals who prefer once-daily XR dosing. Tolerability varies from person to person; for some, quetiapine may be associated with fewer extrapyramidal symptoms, while others may experience weight gain or metabolic changes that require active management.

Quetiapine for bipolar I disorder

Quetiapine is approved for treating both acute manic and mixed episodes of bipolar I disorder, either as monotherapy or with lithium or valproate, and for bipolar depression. During manic episodes, quetiapine helps reduce elevated mood, decreased need for sleep, pressured speech, and impulsivity. In bipolar depression, it can improve low mood, diminished pleasure, sleep disturbance, and functional impairment.

Your prescriber will tailor the dose for each phase of the illness. Because bipolar disorder often requires long-term maintenance therapy, many patients continue quetiapine after stabilization to reduce the risk of relapse. The XR formulation may simplify once-daily dosing, particularly for individuals who prefer nighttime administration and a more stable plasma concentration.

Adjunctive treatment for major depressive disorder (adults)

In adults with major depressive disorder who have not responded well to antidepressants alone, quetiapine XR can be added as adjunctive therapy. This decision is made carefully, taking into account potential benefits and side effects such as sedation and metabolic effects. The objective is to improve depressive symptoms, energy, sleep quality, and overall functioning under close clinical supervision.

How quetiapine works (mechanism of action)

Quetiapine modulates several neurotransmitter receptors:

• It antagonizes dopamine D2 receptors, which is thought to help reduce psychotic symptoms.
• It antagonizes serotonin 5-HT2A receptors, which contributes to its atypical profile and may lower the risk of certain movement-related side effects compared with older antipsychotics.
• Its active metabolite, norquetiapine, partially agonizes 5-HT1A receptors and inhibits norepinephrine transporters, which can support antidepressant and anxiolytic effects.
• Antihistaminic and alpha-1 adrenergic blockade account for sedation and orthostatic hypotension, particularly during early titration.

This multi-receptor activity explains both clinical benefits and certain adverse effects. Careful dosing and monitoring help optimize outcomes while minimizing risks.

Available formulations and strengths

In the U.S., quetiapine is available in the following forms:

• Immediate-release (IR) tablets: common strengths are 25 mg, 50 mg, 100 mg, 200 mg, 300 mg, and 400 mg.
• Extended-release (XR) tablets: common strengths include 50 mg, 150 mg, 200 mg, 300 mg, and 400 mg, designed for once-daily dosing.

IR tablets may be taken once or twice daily as directed. XR tablets must be swallowed whole and should not be split, crushed, or chewed. Your prescriber will determine the formulation and schedule that best fits your diagnosis and daily routine.

Typical adult dosing and titration

Do not change your dose unless instructed by your prescriber. The following are commonly referenced ranges; your individual plan may differ:

Schizophrenia (adults)

• IR: Start generally at 25 mg twice daily on Day 1; titrate over several days to about 300–400 mg/day in divided doses. Some patients may need 150–750 mg/day.
• XR: Often initiated at 300 mg once nightly and adjusted as needed, typically 400–800 mg/day.

Bipolar I mania (monotherapy or adjunct)

• IR: Initial 50 mg twice daily on Day 1, titrating up to a target range often around 400–800 mg/day, as tolerated.
• XR: Start 300 mg once daily, then increase to 400–800 mg/day based on response and tolerability.

Bipolar depression (adults)

• IR or XR: Many regimens begin at 50 mg nightly and titrate to about 300 mg nightly by Day 4, per FDA labeling.

Adjunct for major depressive disorder (adults)

• XR: Commonly initiated at 50 mg to 150 mg nightly and titrated to 150–300 mg nightly if needed.

Special populations: For patients with hepatic impairment, lower starting doses (e.g., 25 mg/day) with slow titration are recommended. No routine adjustment is required for renal impairment, but clinical judgment prevails. Elderly patients are more sensitive to orthostatic changes and sedation—start low and go slow.

Safety, boxed warnings, and precautions

Like all antipsychotics, quetiapine carries important safety considerations:

• Boxed warning: Increased mortality in elderly patients with dementia-related psychosis. Quetiapine is not approved for this population.
• Boxed warning: Antidepressants, including quetiapine when used as adjunctive therapy, may increase the risk of suicidal thoughts and behaviors in children, adolescents, and young adults. Monitor closely, especially at initiation and dose changes.
• Metabolic effects: Weight gain, elevated blood glucose, and lipid abnormalities may occur. Baseline and periodic monitoring of weight/BMI, fasting glucose or A1c, and lipid profile is recommended.
• Somnolence and sedation: Common, particularly during titration; take XR at night unless otherwise directed. Use caution when driving or operating machinery.
• Orthostatic hypotension: Dizziness or fainting can occur, especially after dose increases. Rise slowly from sitting or lying positions and stay hydrated.
• Extrapyramidal symptoms and tardive dyskinesia: Risk is lower than with many older antipsychotics but still possible; report unusual movements or restlessness promptly.
• Neuroleptic malignant syndrome (rare but serious): Symptoms include high fever, muscle rigidity, confusion, and autonomic instability. Seek emergency care if suspected.
• Cardiac considerations: Use cautiously in patients with known QT prolongation, arrhythmias, or those taking other QT-prolonging drugs.
• Lens changes: Periodic eye exams may be considered in long-term use, per some clinical practices.

Common and serious side effects

Not every patient experiences side effects, and many are temporary during early titration. Contact your healthcare professional if symptoms are severe or persistent.

Common side effects

• Drowsiness, fatigue, or sedation
• Dizziness or lightheadedness (may be worse when standing up quickly)
• Dry mouth or constipation
• Increased appetite and weight gain
• Headache
• Indigestion or mild nausea
• Transient increases in triglycerides or cholesterol

Serious side effects—seek medical help immediately

• Signs of neuroleptic malignant syndrome (fever, muscle rigidity, confusion, unstable blood pressure/heart rate)
• Symptoms of severe hyperglycemia (excessive thirst, frequent urination, fruity breath)
• Severe dizziness or fainting, chest pain, new palpitations
• New or worsening suicidal thoughts, agitation, or unusual behavior changes
• Signs of severe allergic reaction (rash, swelling, trouble breathing)
• Uncontrolled movements (tardive dyskinesia), muscle stiffness, or restlessness

Drug interactions

Quetiapine is metabolized primarily by CYP3A4. Many interactions involve medications or foods that inhibit or induce this enzyme. Always tell your prescriber and pharmacist about all prescription drugs, OTC medicines, vitamins, and herbal products you use.

Examples include:

• Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir): may raise quetiapine levels; dose reductions or alternatives may be necessary.
• Strong CYP3A4 inducers (e.g., carbamazepine, phenytoin, rifampin, St. John’s wort): may lower quetiapine levels and reduce effectiveness.
• Other CNS depressants (e.g., benzodiazepines, opioids, alcohol): additive sedation and respiratory depression risks.
• Antihypertensives: increased risk of orthostatic hypotension when combined.
• QT-prolonging drugs: concurrent use requires caution and clinical monitoring.
• Grapefruit or grapefruit juice: can increase quetiapine exposure; generally avoid unless your clinician advises otherwise.

This list is not exhaustive. Your care team can help manage potential interactions, adjust doses, or choose safer alternatives when needed.

How to take quetiapine

Follow your prescriber’s directions exactly. Do not stop quetiapine suddenly without medical advice. If you miss a dose, take it as soon as you remember unless it is close to the time of your next dose—never double up to “catch up.”

• IR tablets: may be taken with or without food, once or twice daily as prescribed.
• XR tablets: take once daily in the evening, swallow whole—do not crush, chew, or split.
• Avoid alcohol and use caution with activities requiring alertness until you know how quetiapine affects you.

Monitoring during treatment

Your healthcare professional may monitor:

• Weight/BMI at baseline and periodically
• Fasting glucose or A1c and lipid profile
• Blood pressure and heart rate
• Symptoms of movement disorders or restlessness
• Mood, sleep, and overall functioning

Pregnancy and breastfeeding

Use during pregnancy should be individualized. Third-trimester antipsychotic exposure may be associated with symptoms in newborns such as agitation, respiratory distress, or feeding difficulties. If you are pregnant, plan to become pregnant, or are breastfeeding, discuss risks and benefits with your clinician. Do not start or stop quetiapine on your own. If used while breastfeeding, monitor infants for excessive sleepiness or feeding issues and consult pediatric guidance.

Special populations and dose adjustments

Some individuals need careful titration and closer observation:

• Elderly patients: start with lower doses due to heightened sensitivity to sedation and orthostatic hypotension.
• Hepatic impairment: initiate therapy at 25 mg/day with gradual increases as tolerated.
• Renal impairment: no routine dose adjustment, but clinical monitoring is prudent.
• History of cardiovascular disease, seizures, or metabolic syndrome: discuss risks and monitoring plans before starting therapy.

Quetiapine IR vs XR: which is right for you?

Both IR and XR formulations contain the same active ingredient. Key differences include dosing frequency and release characteristics:

• IR: Often taken once or twice daily; allows flexible titration and dosing schedules.
• XR: Taken once nightly; designed to provide a smoother pharmacokinetic profile and may improve adherence in some patients.

Your prescriber will consider your diagnosis, symptom patterns, daily routine, side-effect profile, and insurance coverage when choosing a formulation. Some patients transition from IR to XR for convenience; others remain on IR for targeted dosing during the day and at night.

Addressing common questions

Is quetiapine used for sleep?

Quetiapine can cause sedation, and some clinicians may consider it in specific psychiatric contexts where insomnia is a prominent symptom. However, it is not FDA-approved solely as a sleep medication, and risks like metabolic changes must be weighed. Discuss the most appropriate treatment for insomnia with your clinician.

How long does it take to work?

Sleep and anxiety symptoms may improve within days as titration progresses. Antipsychotic and mood-related benefits may take 1–2 weeks or longer, with continued improvement over several weeks. Keep follow-up appointments to evaluate response and make dose adjustments.

Can quetiapine be stopped suddenly?

Abrupt discontinuation is not recommended. Your prescriber may suggest a gradual taper to reduce the risk of withdrawal-like effects and symptom recurrence.

Storage, refills, and medication safety

• Store at room temperature, away from moisture and heat.
• Keep out of reach of children and pets.
• Do not share your medication with others.
• Track refills and schedule follow-ups to avoid running out, as continuity of therapy is important.

Pharmacist’s tips for taking quetiapine

For best results:

• Take XR tablets in the evening as directed; do not crush or chew.
• Rise slowly from sitting or lying positions to reduce dizziness.
• Maintain healthy habits—balanced diet and physical activity can help mitigate weight and metabolic changes.
• Avoid alcohol and limit grapefruit products unless your clinician says otherwise.
• Report new or unusual mood or behavior changes promptly, especially during dose changes.

Precautions

Do not use quetiapine if you have a known allergy to it or any component of the formulation. Tell your prescriber about all medical conditions, including diabetes, high cholesterol, low blood pressure, heart rhythm issues, seizures, liver problems, and any personal or family history of eye conditions. Review all drugs and supplements you take to identify potential interactions.

Reporting side effects

If you experience side effects, contact your healthcare professional. In the U.S., you can report adverse reactions to the FDA’s MedWatch program. Seek urgent help for severe symptoms such as chest pain, fainting, trouble breathing, high fever with stiffness, or new suicidal thoughts.

How to start treatment in the USA

Because quetiapine is prescription-only in the United States, a licensed healthcare professional must evaluate your condition and determine whether it is appropriate for you. Many patients begin with an in-person appointment or a telehealth consultation. If prescribed, you can fill the medication at a local pharmacy or through a mail-order service that ships to your address. Verify that the pharmacy is state-licensed, provides pharmacist counseling, and clearly states delivery timelines and privacy practices.

Our recommendations

To support successful treatment outcomes, we recommend that patients:

• Engage in regular follow-up with their prescriber to review efficacy and tolerability.
• Learn about potential side effects and monitoring needs before starting therapy.
• Adopt lifestyle measures to support cardiometabolic health (nutrition, exercise, sleep hygiene).
• Use only licensed U.S. pharmacies and telehealth providers that require valid prescriptions.
