Neurontin vs Seroquel
Introduction
For individuals with conditions such as epilepsy, bipolar disorder, or other types of mental/mood disorders, certain medications that influence the balance of specific compounds in the brain can aid in managing symptoms and promoting stability. Neurontin (Gabapentin) and Seroquel (Quetiapine) are two such drugs often prescribed for these purposes. Both impact different pathways within the brain but each has effects that help to stabilize mood and control seizures. Neurontin is primarily used to treat seizures as it affects chemicals and nerves in the body which are involved in causing seizures and some types of pain. Seroquel on the other hand is an atypical antipsychotic drug which works by affecting various neurotransmitters, particularly serotonin and dopamine, to improve mood swings, thinking processes and enable a regular pattern of sleep.

What is Neurontin?
Gabapentin (the generic name for Neurontin) was initially developed as an anti-seizure medication. Later, it was found to be effective in treating nerve pain and is now commonly used off-label for the treatment of a variety of conditions including anxiety, insomnia, and bipolar disorder. Gabapentin works by decreasing abnormal excitement in the brain and changing the way the body senses pain.
On the other hand, Quetiapine (the generic name for Seroquel) belongs to a class of medications known as atypical antipsychotics. It is primarily used to treat schizophrenia and bipolar disorder but can also be prescribed off-label for various conditions such as depression or sleep disorders. This medication works by adjusting levels of dopamine and serotonin in your brain which helps improve mood, thinking processes, and behavior.
Although both drugs are utilized broadly across psychiatric settings due to their versatility in managing multiple symptoms associated with different disorders they do have distinct mechanisms of action that result in different side effect profiles.
What conditions is Neurontin approved to treat?
Neurontin, also known as gabapentin, is approved for the treatment of various neurological conditions:
- Postherpetic neuralgia (pain following shingles)
- Partial onset seizures in adults and children 3 years of age and older with epilepsy
- Adjunctive therapy in the treatment of partial onset seizures
On the other hand, Seroquel is a medication primarily used to treat psychiatric conditions such as:
- Schizophrenia
- Bipolar disorder
- Major depressive disorder (as an add-on treatment)
How does Neurontin help with these illnesses?
Neurontin, also known as gabapentin, helps manage conditions such as epilepsy and neuropathic pain by increasing the amount of GABA (gamma-Aminobutyric acid) available in the synapses of the brain. It does this by blocking certain calcium channels on neurons which reduces excitatory neurotransmitter release. GABA is a neurotransmitter that acts to inhibit signals in the brain and nervous system, reducing neuronal excitability throughout the nervous system. This plays an important role in managing symptoms like seizures or nerve pain.
On the other hand, Seroquel or quetiapine primarily works by acting on serotonin and dopamine receptors in your brain to reduce symptoms associated with schizophrenia or bipolar disorder. Dopamine is thought to be overactive in brains of people with these conditions; therefore, by decreasing dopamine activity through its antagonistic effect on D2 receptors and boosting serotonin activity via 5HT2A receptor antagonism, Seroquel can help patients manage their condition and stabilize their mood.
What is Seroquel?
Seroquel is a brand name for quetiapine, an atypical antipsychotic medication. It affects several neurotransmitters in the brain including serotonin and dopamine by blocking their receptors. The medication was first approved by the FDA in 1997. Unlike Neurontin (generic name gabapentin), which primarily targets GABA receptors to exert its effect, Seroquel operates mostly on serotonin and dopamine pathways. This different mechanism of action results in a unique side-effect profile compared to drugs like Neurontin; for example, it does not cause significant drowsiness or 'brain fog', common side effects associated with medications affecting GABA activity such as Neurontin. Furthermore, Seroquel's influence on both serotonin and dopamine can be beneficial for treating symptoms of bipolar disorder and schizophrenia, particularly in patients who do not respond well to standard mood stabilizers or antipsychotics.
What conditions is Seroquel approved to treat?
Seroquel is a medication that has been approved by the FDA for the treatment of several serious mental health conditions, including:
- Schizophrenia, an illness characterized by disordered thinking and hallucinations
- Bipolar disorder, a condition where individuals experience extreme mood swings from manic episodes to depressive phases
- As an add-on treatment for major depressive disorder when other medications have not worked sufficiently.
How does Seroquel help with these illnesses?
Seroquel is an antipsychotic medication that works by adjusting the levels of dopamine and serotonin, two key neurotransmitters in the brain. Dopamine plays a vital role in motivation, reward, and attention while serotonin helps regulate mood, appetite, and sleep. Imbalances in these neurotransmitters can contribute to conditions such as schizophrenia or bipolar disorder. Unlike Neurontin which affects GABA receptors to control seizures and nerve pain, Seroquel directly influences these central neurotransmitter systems for managing symptoms of mental health disorders. This makes it often prescribed when patients show poor response to typical mood stabilizers (like Neurontin), or it may be combined with them for better outcomes.
How effective are both Neurontin and Seroquel?
Both gabapentin (Neurontin) and quetiapine (Seroquel) are medications used in the management of various mental health disorders, but they act on different neurotransmitters and have distinct uses. Gabapentin was initially approved by the FDA for seizure disorders while quetiapine is an atypical antipsychotic primarily used to treat schizophrenia and bipolar disorder.
The efficacy of both drugs has been extensively studied in clinical trials. For instance, a 2002 study found that gabapentin effectively managed symptoms of generalized anxiety disorder similar to lorazepam, with fewer side effects such as sedation or dependency risks. Conversely, quetiapine demonstrated efficiency in treating bipolar mania or depression symptoms in several double-blind clinical trials.
A review conducted in 2011 indicated that gabapentin can be effective from the first week of treatment when used adjunctively for partial seizures. Its safety profile is generally favorable over other antiepileptics; it also appears well-tolerated among elderly populations due to its renal excretion mechanism which makes it less likely to interact with other medications.
On the other hand, a meta-analysis conducted in 2017 suggested that quetiapine seems more effective than placebo for schizophrenia treatment while showing comparable efficacy against other typical and atypical antipsychotics. However, its use often involves co-prescription alongside mood stabilizers like lithium or valproate especially for patients suffering from acute manic episodes associated with bipolar disorder.
While both drugs provide therapeutic benefits across their respective indications, they also carry potential risks including sedation and weight gain which should be taken into account when considering them as treatment options.

At what dose is Neurontin typically prescribed?
Oral dosages of Neurontin range from 900 to 3600 mg/day, but studies have shown that starting with a dosage of 300 mg three times daily is effective for treating seizures in most adults. Children and adolescents may be started on an initial dose according to their weight. In either population, dosage can be increased after a week if there is no response. The maximum dosage that should not be exceeded in any case is 3600 mg/day.
On the other hand, oral dosages of Seroquel range from 50-800 mg/day when used for schizophrenia or bipolar disorder treatments. However, it's typically advised to start with a lower dose such as 25mg twice daily which can then gradually increase over several days depending on individual patient needs and responses. It's important not to exceed the recommended maximum daily dose of Seroquel which stands at 800mg per day.
At what dose is Seroquel typically prescribed?
Seroquel therapy typically begins with a dose of 25 mg/day. The dosage can then be increased to 50 mg/day, divided into two doses that are spaced 12 hours apart. If necessary and well-tolerated, the daily dose may further increase in increments of 25 - 50 mg divided two or three times on the second and third day, as needed to reach an effective level. The maximum recommended dose is up to 800 mg/day, which should be divided into two or more smaller doses throughout the day, if there's no response to treatment at lower dosages after some weeks. As always, changes in dosage should only be carried out under strict medical supervision.

It's important for patients taking Seroquel to closely monitor these potential side effects and consult their medical provider if any persist.
Are there any potential serious side effects for Seroquel?
While Seroquel is generally well-tolerated, it's important to be aware of potential side effects that may require immediate medical attention. These can include:
- Signs of an allergic reaction, such as hives; difficulty breathing; swelling in your face, lips, tongue or throat.
- Any signs suggestive of high blood sugar like increased thirst and urination, excessive hunger accompanied by weight loss, fruity breath odor.
- Symptoms indicative of a stroke: sudden numbness or weakness (particularly on one side of the body), severe headache, slurred speech or balance problems.
- Feeling faint upon standing up quickly due to low blood pressure (postural hypotension).
- Unusual changes in mood or behavior including worsening depression and suicidal thoughts.
- Rapid heartbeat which might be related to a potentially life-threatening condition called Torsades de Pointes.
If you notice any unusual symptoms while taking Seroquel, seek urgent medical attention.
Contraindications for Neurontin and Seroquel?
Both Neurontin and Seroquel, among other antipsychotic medications, may intensify symptoms of depression in certain individuals. If you notice your mood deteriorating or find yourself having suicidal thoughts or tendencies, it is critical to seek medical help immediately.
Neither Neurontin nor Seroquel should be taken if you are currently using any opioid drugs. The combination of opioids and these medications can increase the risk of severe side effects such as difficulty breathing or even death. Always inform your doctor about all medications and substances that you are taking; opioids must be completely cleared from your system before starting a regimen with either Neurontin or Seroquel to prevent dangerous interactions.
How much do Neurontin and Seroquel cost?
For the brand name versions of these drugs:
- The price for 60 tablets of Neurontin (300 mg) averages around $400, which works out to roughly $13-$26/day depending on your dose.
- The price for 30 tablets of Seroquel (100 mg) is about $600, averaging approximately $20/day.
Therefore, if you are in a higher dosage range for Neurontin (i.e., 600 mg/day or higher), then brand-name Seroquel may be less expensive on a per-day treatment basis. Please remember that cost should not be the primary factor in determining which medication is right for you.
As for their generic counterparts - Gabapentin and Quetiapine:
- Gabapentin (300mg capsules) can be found in packs from 90 capsules onwards with approximate costs ranging from $0.75 to $2.25 per day based on typical dosages between 900mg and 2700mg daily.
- Quetiapine comes in various pack sizes starting from as low as 15 up to several hundreds tablets (100 mg), with the cost starting at around $0.50/day and increasing depending on both dosage and pack size chosen.
Popularity of Neurontin and Seroquel
Gabapentin, commonly known under the brand name Neurontin, was prescribed to approximately 17.8 million people in the US in 2020. It accounted for nearly half of prescriptions for anticonvulsants and is also used off-label for a variety of conditions such as nerve pain, hot flashes, restless legs syndrome and alcohol withdrawal. The prevalence of gabapentin has been steadily increasing since its approval by FDA in late 1993.
Quetiapine, available as brand name Seroquel among others, was prescribed to about 5 million individuals in the USA during 2020. In terms of antipsychotic prescriptions in the US, quetiapine accounts for close to 15% while contributing considerably less towards overall psychiatric medication prescriptions. This drug is often utilized not only as an atypical antipsychotic but also off-label for insomnia due to its sedative properties. Its usage patterns have maintained relative constancy over recent years.
Conclusion
Both Neurontin (gabapentin) and Seroquel (quetiapine) are widely used in the management of various psychiatric conditions. They have been supported by multiple clinical studies, demonstrating their effectiveness as compared to placebo treatments. Occasionally, these medications may be combined under careful physician consideration due to potential contraindications. The primary mechanism of action for Neurontin is its ability to modulate calcium channels while Seroquel primarily acts on dopamine and serotonin receptors, leading them to be prescribed under different circumstances.
Neurontin is frequently used for neuropathic pain or epilepsy while Seroquel is typically utilized in schizophrenia and bipolar disorder treatment plans but can also serve as an adjunct therapy for depression. Both drugs are available in generic form which makes them a more affordable option especially for out-of-pocket patients.
It should be noted that both Neurontin and Seroquel might require an adjustment period during which effects might not be immediately noticeable.
The side effect profile between the two drugs varies with Neurontin commonly causing dizziness, somnolence, and peripheral edema whereas Seroquel can cause sedation, weight gain, dry mouth among others. With each medication regimen initiation or changes in dosages patients should closely observe any mood alterations or unanticipated reactions; prompt medical help must sought if worsening symptoms or thoughts about self-harm arise.
