Seroquel vs Ambien
Introduction
For patients with insomnia or other sleep disorders, certain drugs that interact with the chemicals in the brain that regulate sleep can help in managing symptoms and ensuring a more restful night's sleep. Seroquel and Ambien are two such drugs that are commonly prescribed for sleep disorders. They each interact with different chemicals in the brain, but both have sleep-inducing effects in patients with sleep disorders. Seroquel, generically known as quetiapine, is classified as an atypical antipsychotic, primarily affecting dopamine and serotonin receptors in the brain. On the other hand, Ambien, also known as zolpidem, is a sedative-hypnotic that works by enhancing the effects of gamma-aminobutyric acid (GABA), a chemical in the brain that inhibits the activity of nerve cells, leading to sedation.
What is Seroquel?
Quetiapine (the generic name for Seroquel) is an atypical antipsychotic medication, a significant advance from the first wave of antipsychotic medications known as typical antipsychotics. Quetiapine was first approved by the FDA in 1997. Seroquel works by adjusting the levels of dopamine and serotonin in the brain, thereby improving thinking, mood, and behavior. It is prescribed for the treatment of schizophrenia, bipolar disorder, and as an adjunct treatment for major depressive disorder. Seroquel has a broader influence on multiple neurotransmitters including serotonin, dopamine, histamine, and adrenergic receptors, which can result in it having more side effects than other medications that have a more selective influence on neurotransmitters. On the other hand, Zolpidem (the generic name for Ambien) is a sedative primarily used for the short-term treatment of sleeping problems. Ambien works by slowing brain activity, allowing the user to sleep. It affects chemicals in the brain that may be unbalanced in people with sleep problems.
What conditions is Seroquel approved to treat?
Seroquel is approved for the treatment of various mental health disorders:
- Schizophrenia
- Bipolar disorder, including manic episodes associated with bipolar I disorder and maintenance treatment of bipolar I disorder
- Major depressive episodes in bipolar disorder, when used alongside antidepressants. It's also utilized off-label for insomnia, although it carries potential risks due to its potent antipsychotic effects.
How does Seroquel help with these illnesses?
Seroquel helps manage symptoms of schizophrenia and bipolar disorder by influencing several neurotransmitters in the brain, including serotonin and dopamine. It does this by acting as an antagonist at various neurotransmitter receptors, meaning it binds to these receptors but does not activate them, thus blocking their activation by other substances. Neurotransmitters are chemicals that act as messengers in the brain and throughout the body, playing vital roles in mood, cognition, sleep, appetite, and more. Individuals with schizophrenia and bipolar disorder often have imbalances in these neurotransmitters. Therefore, by influencing these neurotransmitters, Seroquel can limit the negative effects of these conditions and help patients manage their symptoms and stabilize their mood. Seroquel is also often used off-label to treat insomnia due to its sedative effects.
What is Ambien?
Ambien, a brand name for zolpidem, is a central nervous system depressant that is typically prescribed for insomnia. It falls under the classification of drugs known as sedative-hypnotics, which work by slowing activity in the brain, allowing for a state of sleep. It was first approved by the FDA in 1992. As zolpidem is not an antipsychotic medication, it does not have the same mechanisms of action as drugs like Seroquel. This means that its side-effect profile is also different, particularly in that it does not usually cause prolonged drowsiness or potential weight gain associated with many antipsychotic medications such as Seroquel. The effects of zolpidem, in slowing brain activity, can be beneficial for the treatment of insomnia, especially in patients who do not respond well to antipsychotic or antidepressant drugs used off-label for sleep disorders.
What conditions is Ambien approved to treat?
Ambien, also known as zolpidem, is primarily approved by the FDA for managing:
- Short-term insomnia characterized by difficulties with sleep initiation
- Some forms of chronic insomnia under close medical supervision
It's important to note that its use should typically be limited to 1 to 2 weeks or less.
How does Ambien help with these illnesses?
Ambien, like Seroquel, impacts neurotransmitter activity in the brain, but it targets different mechanisms to promote sleep. Ambien works by enhancing the effects of GABA, a neurotransmitter that inhibits activity within the nervous system. This results in sedative effects that help to initiate sleep. Ambien primarily affects the sleep-wake cycle, making it a popular choice for short-term treatment of insomnia. Its action is more specific compared to Seroquel, which not only influences sleep but also mood and perception due to its wider range of neurotransmitter interactions. This makes Ambien less likely to cause daytime drowsiness or other side effects related to mood and perception. Therefore, Ambien is often preferred for patients primarily struggling with sleep initiation, while Seroquel might be used when other symptoms, such as mood disorders, are also present.
How effective are both Seroquel and Ambien?
Quetiapine (Seroquel) and zolpidem (Ambien) are both recognized as effective treatment options for insomnia, although they were initially approved by the FDA to treat different disorders and they act on different neurotransmitters. Quetiapine, an atypical antipsychotic, was initially approved for the treatment of schizophrenia and bipolar disorder, while zolpidem was approved for short-term treatment of insomnia. The efficacy of these drugs in promoting sleep was directly studied in various clinical trials; they demonstrated similar efficiency in improving sleep quality and latency.
A 2005 meta-analysis of quetiapine demonstrated its efficacy in treating insomnia associated with psychiatric disorders, starting from the first week of treatment. Moreover, its side effect profile was found to be favorable among many other antipsychotics, and it is well-tolerated in a wide range of populations. Further, as it was one of the first atypical antipsychotics developed, there is a significant history and study of its effectiveness in treating insomnia. The dose showing optimal efficacy for sleep induction is thought to be 25-100 mg/night, and in addition to improving sleep, it also appears to improve daytime functioning.
On the other hand, a 2017 review and meta-analysis indicated that zolpidem seems to be more effective than placebo in treating insomnia and that it is similar in efficacy to other common sleep aids. Nonetheless, zolpidem is typically considered a first-line treatment option for insomnia. Significant research on its use involves zolpidem prescribed as a stand-alone treatment, so data confirming its efficacy is robust. Further, the evidence to support zolpidem as significantly improving sleep onset latency and sleep quality is well-established. Nonetheless, due to its unique pharmacology, zolpidem may be an optimal treatment for patients who have difficulty falling asleep or staying asleep.
At what dose is Seroquel typically prescribed?
Oral dosages of Seroquel for treating schizophrenia in adults typically start from 25 mg/day, increased to a recommended dose of 150-750 mg/day. For bipolar disorder treatment, adults may start with an oral dosage of 50 mg/day that can be increased gradually up to a maximum recommended dose of 800 mg/day based on the patient's response and tolerance. However, children and adolescents' dosages must be determined by their doctor. On the other hand, Ambien is used specifically for insomnia; its standard adult dosage begins at 5–10mg just before bedtime for immediate release tablets or 6.25-12.5mg for extended-release tablets (Ambien CR). In either case, it should not exceed one tablet per day right before bed.

At what dose is Ambien typically prescribed?
Ambien treatment is typically initiated at a dosage of 5-10 mg/day for men and 5 mg/day for women, taken immediately before bedtime. The dose can be increased to a maximum of 10 mg per day if the initial lower dose does not produce adequate sleep after an adjustment period. This medication should only be taken once per night, right before the patient plans to sleep for seven hours or longer. If there's no significant improvement in sleep patterns or if insomnia persists after seven to ten days of treatment, further evaluation may be necessary as this might signify an underlying medical illness.

Are there any potential serious side effects for Seroquel?
While both Seroquel and Ambien are used to treat conditions related to sleep and mental health, they do have potential side effects:
For Seroquel, these may include:
- Thoughts about suicide or self-harm, particularly in younger patients
- Severe allergic reactions: hives, difficulty breathing, swelling in your face or throat. Seek emergency attention if this occurs.
- Changes in vision, such as blurred or tunnel vision, eye pain or swelling, or seeing halos around lights.
- Cardiovascular symptoms like fast or pounding heartbeats, fluttering in your chest, shortness of breath, and sudden dizziness (like you might pass out).
- Low sodium levels in the body - symptoms may include a headache, confusion, slurred speech, severe weakness, vomiting, loss of coordination, or feeling unsteady.
- Severe nervous system reaction - very stiff (rigid) muscles, high fever, sweating, confusion, fast or uneven heartbeats, tremors, or feeling like you might pass out.
- Signs of neuroleptic malignant syndrome: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
On the other hand, Ambien may cause:
- Complex sleep behaviors such as sleep-walking, sleep-driving, and engaging in other activities while not fully awake. If these occur, stop taking Ambien and contact your doctor.
- Allergic reactions: hives, difficulty breathing, swelling in your face or throat. If these occur, seek emergency attention.
- Abnormal thoughts and behavior, such as aggressiveness, confusion, hallucinations, or suicidal thoughts.
- Memory loss
- Anxiety or depression.
If you experience any of these side effects while taking Seroquel or Ambien, contact your healthcare provider immediately.
What are the most common side effects for Ambien?
Ambien, a commonly prescribed sleep aid, can have several side effects. These include:
- Dry mouth or throat discomfort
- Dizziness and light-headedness
- Daytime drowsiness
- Nausea or upset stomach
- Headache or muscle pain
- Unusual dreams or nightmares
- Impaired vision, particularly blurred vision
- Feeling anxious and nervous - this is more common when waking up from the medication. Fast heartbeat can also occur in some users.
Bodily changes such as rash, constipation which affects appetite, increased urination are less common but may still occur. In rare cases individuals might experience confusion and agitation with Ambien usage. It's important to note that while weight loss isn't typically associated with Ambien use directly; if you're experiencing unusual weight shifts, it could be due to an underlying issue potentially exacerbated by disturbed sleep patterns.
Are there any potential serious side effects for Ambien?
While Ambien has been a great help for many suffering from insomnia, it can occasionally cause severe side-effects. If you notice any of the following symptoms while on Ambien, seek medical attention immediately:
- Allergic reactions: hives; difficulty breathing; swelling of your face, lips, tongue, or throat
- Changes in behavior and mood swings: anxiety, aggression, feeling restless or agitated
- Depression or suicidal thoughts
- Memory issues such as amnesia (forgetting)
- Hallucinations or confusion
- Unusual thoughts and risk-taking behavior
- Decreased inhibitions with no fear of danger
- Engaging in activities while not fully awake that you do not recall later like driving ("sleep-driving") Also be aware that increased sleepiness during daytime hours might occur. While this is less severe than the aforementioned symptoms, it's still important to discuss these effects with your doctor if they persist.
Contraindications for Seroquel and Ambien?
Just as with most other psychiatric medications, both Seroquel and Ambien may exacerbate symptoms of depression or anxiety in some individuals. If you notice an increase in suicidal ideation, thoughts, or behavior, or your mood disorder symptoms are worsening, please seek immediate medical attention.
Neither Seroquel nor Ambien should be taken if you are taking, or have recently been taking, drugs that interact with these medications, including certain antifungal medications or antibiotics. It's crucial to inform your physician about any other medications you are currently using, as some might interfere with Seroquel or Ambien, leading to potentially serious side effects.
It's recommended that you wait for at least a week after stopping certain medications, such as strong CYP3A4 inhibitors, before starting on Seroquel or Ambien to prevent harmful interactions. Always adhere to your doctor’s advice regarding medication use and discontinuation.
How much do Seroquel and Ambien cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Seroquel (100 mg) averages around $800, which works out to $13–26/day, depending on your dose.
- The price of 30 tablets of Ambien (10 mg) averages around $200, working out to approximately $6.67/day.
Thus, if you are in the higher dosage range for Seroquel (i.e., 200 mg/day or higher), then brand-name Ambien is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these drugs is right for you.
For the generic versions of Seroquel (quetiapine) and Ambien (zolpidem), costs are significantly lower:
- Quetiapine (100 mg tablets) is available in packs of 30 tablets and above, with approximate costs of $0.25 to $0.75 per day for dosages of 100 mg/day, or between $0.50 and $1.50 per day if you are taking more typical dosages of 200 to 300 (or even 400) mg/day.
- Zolpidem is available in packs of 30 up to 100 tablets (10 mg), with the cost to you starting from as low as $0.10/day (if you buy the largest pack upfront), and not exceeding about $0.40/day.
Popularity of Seroquel and Ambien
Quetiapine, known by the brand name Seroquel, was estimated to have been prescribed to approximately 2.8 million people in the US in 2019. Quetiapine is part of a class of medications known as atypical antipsychotics and accounted for just over 14% of prescriptions within this drug class in the same year. Its use has generally been increasing since its approval by the FDA in 1997.
Zolpidem, including brand versions such as Ambien, was prescribed to about 10 million people in the USA during that same period. Zolpidem accounts for roughly half of all prescriptions for sleep disorder treatments and around a quarter of all insomnia-related medication prescriptions overall. Despite some concerns regarding dependency and side effects associated with long-term use, zolpidem's prevalence has remained relatively steady over recent years due to its effectiveness in managing short-term insomnia.
Conclusion
Both Seroquel (quetiapine) and Ambien (zolpidem) are used to manage insomnia, but they have distinct mechanisms of action and different uses in the clinical setting. Seroquel, an atypical antipsychotic, is primarily used in the treatment of schizophrenia, bipolar disorder, and major depressive disorder but may also be prescribed off-label for insomnia due to its sedating effects. It works by modulating neurotransmitter activity in the brain, specifically dopamine, serotonin, and adrenergic signaling.
On the other hand, Ambien is a hypnotic specifically designed for treating insomnia. It works by enhancing the activity of GABA, an inhibitory neurotransmitter, which helps to calm the brain and promote sleep.
In some cases, the drugs may be used together to manage complex sleep disorders, but this requires careful consideration by a physician due to potential drug interactions and cumulative side effects.
Both Seroquel and Ambien are available in generic form, which can represent significant cost savings, especially for patients paying out of pocket. It's important to note that the effects of these drugs may not be noticeable immediately as it can take time for the body to adjust.
The side effect profiles for these two drugs are different. Seroquel can cause weight gain, dry mouth, and constipation, among other side effects, while Ambien may cause dizziness, headaches, or daytime drowsiness. Regardless of the medication, patients should monitor their reactions closely, especially when starting treatment, and seek medical help immediately if they encounter severe side effects or worsening of their condition.
