Neurontin vs Geodon
Introduction
For patients with epilepsy, bipolar disorder, or schizophrenia, certain drugs that influence the concentrations of neurotransmitters in the brain can help manage symptoms and stabilize conditions. Neurontin and Geodon are two such drugs prescribed for these disorders. Each affects different neurotransmitters in the brain but both have stabilizing effects on patients' cognition and mood.
Neurontin is an anticonvulsant primarily used to treat seizures by reducing abnormal excitement in the brain. It works by affecting GABA (gamma-aminobutyric acid) receptors which play a role in calming nerve activity.
On the other hand, Geodon falls under atypical antipsychotics category designed mainly for treating symptoms associated with psychological disorders like schizophrenia and mania induced by bipolar disorder. It acts as a serotonin-dopamine antagonist influencing levels of dopamine and serotonin.
What is Neurontin?
Gabapentin (the generic name for Neurontin) is an anticonvulsant medication that was initially developed to treat epileptic seizures. It was first approved by the FDA in 1993. However, it has also been found effective in treating neuropathic pain and restless leg syndrome, and as such is often prescribed off-label for these conditions. Gabapentin works by reducing abnormal excitement in the brain, effectively calming nerve activity.
On the other hand, Ziprasidone (the generic name for Geodon) belongs to a class of drugs known as atypical antipsychotics. Approved by the FDA in 2001, Geodon primarily treats symptoms related to schizophrenia and bipolar disorder but can also be used off-label for depression or anxiety disorders. The drug influences both dopamine and serotonin neurotransmitters but with minor effects on norepinephrine.
Each of these medications carries its own risks and benefits; therefore patients should discuss their personal health histories thoroughly with their healthcare provider before starting either treatment.
What conditions is Neurontin approved to treat?
Neurontin is approved for the treatment of various neurological conditions:
- Epilepsy, a common neurologic disorder characterized by recurrent seizures
- Postherpetic neuralgia, a type of nerve pain following herpes zoster (shingles)
On the other hand, Geodon is used to treat different mental/mood disorders:
- Schizophrenia, a chronic and severe mental disorder affecting how a person thinks, feels and behaves
- Bipolar disorder (as monotherapy or in combination with lithium or valproate), also known as manic-depressive illness which causes extreme mood swings that include emotional highs (mania) and lows (depression).
How does Neurontin help with these illnesses?
Neurontin, also known as gabapentin, helps to manage various forms of nerve pain and seizures by affecting the way nerves send messages to the brain. It does this by stabilizing electrical activity in the brain and reducing abnormal excitement of neurons. Gabapentin is a type of medication called a GABA analogue, which was designed to mimic the behavior of one neurotransmitter, gamma-aminobutyric acid (GABA), which plays an important role in suppressing neuronal excitability throughout the nervous system.
On the other hand, Geodon or ziprasidone is an antipsychotic drug that works differently from Neurontin. It functions mainly as a dopamine and serotonin antagonist. This means it blocks these receptors in your brain so that more balanced amounts of dopamine and serotonin can be maintained for longer periods. These two chemicals play vital roles in regulating mood, cognition, reward systems among others things within our body's functioning mechanisms.
It should be noted that while both medications affect neurological processes they are used for very different conditions: Neurontin primarily for epilepsy and neuropathic pain while Geodon treats bipolar disorder and schizophrenia symptoms.
What is Geodon?
Geodon is a brand name for ziprasidone, which is an atypical antipsychotic. It works by modulating the activity of dopamine and serotonin in the brain. Ziprasidone acts as an antagonist at various neurotransmitter receptors - it blocks their action, thus reducing overactivity. Specifically, it has high affinity for dopamine D2 receptors and serotonin 5-HT2A receptors. The drug was first approved by the FDA in 2001.
As Geodon does not belong to typical antipsychotics group, its side-effect profile differs significantly from that class of drugs; particularly noted is its less likelihood to cause extrapyramidal symptoms (motor control problems such as tremors). Additionally, unlike many other atypical antipsychotics like risperidone or olanzapine, use of Geodon doesn't frequently result in weight gain.
The effect on both dopamine and serotonin can be beneficial for treating schizophrenia and acute manic or mixed episodes associated with bipolar disorder – especially in patients who do not respond well to "typical" treatments involving only either dopamine or serotonin systems.
What conditions is Geodon approved to treat?
Geodon is a medication approved by the FDA for the treatment of:
- Schizophrenia, a mental disorder that affects how a person thinks, feels and behaves
- Bipolar disorder, specifically to manage acute manic or mixed episodes. It's also used as maintenance treatment in combination with lithium or valproate
How does Geodon help with these illnesses?
Geodon, or ziprasidone, is a second-generation antipsychotic medication that impacts the levels of dopamine and serotonin in the brain. Dopamine and serotonin are neurotransmitters heavily involved in mood regulation, perception of reality, sleep, attention and other critical cognitive functions. Some studies suggest low levels of these neurotransmitters may be linked to conditions like schizophrenia and bipolar disorder. Geodon asserts its effect by balancing these chemicals within the brain thereby alleviating some symptoms associated with these disorders. Unlike Neurontin which primarily works on GABA receptors for nerve pain and seizures but can also be used for certain mood disorders; Geodon has a broader spectrum of activity affecting more than one type of receptor in the brain. This makes it effective not only as an antipsychotic but potentially useful as an adjunctive treatment in depressive disorders when patients do not respond well to typical antidepressants or require additional support managing their symptoms.
How effective are both Neurontin and Geodon?
Both gabapentin (Neurontin) and ziprasidone (Geodon) have established histories of success in treating a variety of conditions, but they were initially approved by the FDA for different purposes: Neurontin for epilepsy and Geodon for schizophrenia. They act on different neurotransmitters, thus may be prescribed under different circumstances. The effectiveness of gabapentin and ziprasidone has been studied extensively across various clinical trials; both drugs demonstrated efficacy in their respective areas as well as promising safety profiles.
A 2003 meta-analysis reported that gabapentin is effective in managing symptoms related to epilepsy and nerve pain starting from the first week of treatment. Its side effect profile is generally favorable compared to other anticonvulsants, with drowsiness being one common side effect. Further studies indicate its usefulness in treating alcohol dependency due to its calming effects on the nervous system.
On the other hand, a 2017 review indicated that ziprasidone seems to be more tolerable than most typical antipsychotics when used to treat schizophrenia - meaning it's less likely to lead to unpleasant movement disorders often associated with this class of drugs. However, like many atypical antipsychotics, weight gain can still occur as a side effect with Geodon use. Notably though, compared with other similar medications such as olanzapine or clozapine, weight gain appears less severe during treatment with Geodon.
In summary: while these two medicines serve very distinct purposes – Neurontin primarily for seizures/nerve pain/alcohol withdrawal and Geodon mainly for psychotic disorders – both have proven efficacy within their respective domains along with manageable side-effect profiles.
At what dose is Neurontin typically prescribed?
Oral dosages of Neurontin typically start from 300 mg/day and can go up to 3600 mg/day depending on the patient's response and tolerance. For treating seizures, children (aged 3-12) may be started at around 10-15 mg/kg/day; this dosage can be increased after a week if there is no response. The maximum daily dose for adults should not exceed 3600mg in any case.
Geodon, on the other hand, usually starts with an oral dosage of about 20 mg twice a day with food. Depending on the individual's response, your doctor may opt to increase this incrementally over time but it generally does not exceed a total of 160mg per day in divided doses for most people.

At what dose is Geodon typically prescribed?
Geodon treatment typically begins with a dosage of 20 mg twice daily for the first day. The dose can then be increased to 60-80 mg twice daily, depending on individual patient response and tolerability. This dosing should occur with food, as it significantly increases the absorption of Geodon into the body. Geodon doses are usually spaced around 12 hours apart and the maximum recommended dose is 160 mg/day divided into two doses of 80mg each in severe cases or when there is inadequate response to lower dosages after appropriate evaluation period.
What are the most common side effects for Neurontin?
Common side effects of Neurontin (Gabapentin) can include:
- Drowsiness, fatigue or weakness
- Uncoordinated movement
- Nausea and vomiting
- Tremors or shaking
- Changes in mood such as anxiety or nervousness
- Memory problems
- Dry mouth
On the other hand, Geodon (Ziprasidone) may cause:
- Drowsiness, restlessness, insomnia
- Indigestion, nausea or constipation

Both drugs have their own sets of side effects but it's important to note that not everyone will experience these. It is crucial to consult with your healthcare provider before switching medications.
Are there any potential serious side effects for Neurontin?
In comparison to Geodon, Neurontin can have some serious side effects. While these aren't common, they are important to note:
- Thoughts of suicide or self-harm may increase while taking this medication
- Allergic reactions: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing
- Changes in vision including eye pain or swelling and seeing halos around lights
- Rapid heartbeats which may feel like a fluttering in your chest; shortness of breath followed by sudden dizziness could indicate that you might pass out
- Symptoms suggesting low sodium levels - headaches, confusion, slurred speech, weakness at an extreme level leading to vomiting and loss of coordination or unsteady feelings
- Severe nervous system reaction symptoms such as rigid muscles accompanied with high fever and sweating; confusion combined with rapid or uneven heartbeats along with tremors might make you feel like passing out.
If there is an occurrence of any signs suggestive of serotonin syndrome such as agitation, hallucinations coupled with feverish feeling plus sweats and shivers; a fast heartbeat rate coupled with muscle stiffness and twitching resulting in lack of coordination along with nausea/vomiting or diarrhea then medical help should be sought immediately.
What are the most common side effects for Geodon?
Geodon, also known as ziprasidone, has a range of possible side effects including:
- Dry mouth and stuffy nose
- Vision changes or blurred vision
- Nausea, vomiting, loss of appetite or stomach discomfort
- Sleep problems such as insomnia
- Feeling restless or nervous
- Muscle stiffness or spasms
- Dizziness and headaches
- Rapid heartbeat; it is noted that Geodon may cause prolonged QT interval which requires medical attention.
It's important to note that not all patients experience these symptoms and the severity can vary greatly. Always consult with your healthcare provider if you are experiencing any adverse reactions while taking this medication.
Are there any potential serious side effects for Geodon?
While Geodon is widely used and effective for its intended purposes, it carries the risk of several potential side effects which can be serious. These may include:
- Signs of an allergic reaction: hives, difficulty breathing, swelling in your face or throat
- Unusual changes in mood or behavior - including feeling extremely happy or irritable, talking more than usual
- Symptoms related to disruption of the heart's rhythm such as fast or irregular heartbeat
- Convulsions/seizures
- Difficulty with vision: blurred sight, tunnel vision, eye pain or swelling
- Skin reactions: burning sensation in eyes, skin pain followed by a red or purple rash that spreads especially on the face and upper body causing blistering and peeling
In case you experience any of these symptoms while using Geodon stop taking it immediately and seek medical attention without delay.
Contraindications for Neurontin and Geodon?
Similar to the majority of antipsychotic and antiepileptic medications, both Neurontin (gabapentin) and Geodon (ziprasidone) can potentially worsen symptoms in some individuals. If you notice a worsening of your condition or an increase in suicidal thoughts or behavior while taking these drugs, please seek immediate medical attention.
Neither Neurontin nor Geodon should be taken if you are currently using, or have recently used any form of Central Nervous System (CNS) depressants such as opioids or sedatives. Always inform your healthcare provider about any other medications you are taking; CNS depressants would require a certain period to clear from your system to prevent hazardous drug interactions with either gabapentin or ziprasidone.
In addition, both drugs have been associated with serious cardiac side effects, so they should be used cautiously by people who have heart conditions. Like all medication decisions, the decision to use Neurontin versus Geodon is highly individualized and should take into consideration factors like age, health status, existing comorbidities and risk factors for adverse drug reactions.
How much do Neurontin and Geodon cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Neurontin (300 mg) averages around $400, which works out to approximately $13–26/day, depending on your dose.
- The price of 30 capsules of Geodon (40 mg) is about $900, working out to roughly $30/day.
Thus, if you are in the higher dosage range for Neurontin (i.e., 600 mg/day or higher), then brand-name Geodon can be 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 Neurontin (gabapentin) and Geodon (ziprasidone), costs are significantly lower:
- Gabapentin (300 mg tablets) is available in packs from 30 capsules upwards with approximate costs ranging from $0.35 to $1.10 per day for dosages starting at 100 mg/day up to more typical dosages between 900 and 1800mg.
- Ziprasidone comes in packs ranging from15 up to several hundred capsules(20 -160mg each), with daily cost starting as low as about $.25/day when buying larger amount upfront and usually not exceeding around$2-$3 /day .
Popularity of Neurontin and Geodon
Gabapentin, also known by the brand name Neurontin, is an anticonvulsant medication often used to treat seizures and nerve pain. It was estimated that about 64 million prescriptions for gabapentin were filled in the US in 2020. This marks a significant increase from previous years - between 2012 and 2016 alone, gabapentin prescribing increased by approximately 49%. Gabapentin accounted for nearly one-third of all anticonvulsant prescriptions in the US.
Ziprasidone, sold under the brand name Geodon among others, is an atypical antipsychotic primarily used to treat schizophrenia and bipolar disorder. In comparison to gabapentin's widespread use, ziprasidone was prescribed around just under a million times in the USA during 2020. Despite this lower overall prescription rate compared with gabapentin, it should be noted that usage trends can vary significantly based on specific patient populations and treatment indications.
Conclusion
Both Neurontin (gabapentin) and Geodon (ziprasidone) have well-established records of use in patients with neurological and psychiatric disorders, backed by numerous clinical studies indicating their effectiveness. The two drugs may sometimes be used in conjunction, but this should always be under the careful supervision of a physician due to potential interactions. They operate via different mechanisms: Neurontin is primarily an anticonvulsant that acts on the GABA neurotransmitter system, often prescribed for nerve pain or seizures, while Geodon is an atypical antipsychotic affecting both dopamine and serotonin receptors, most commonly used in treating bipolar disorder and schizophrenia.
Both medications are available as generics which can lead to significant cost savings for patients who must pay out-of-pocket expenses. Like many psychiatric medications, both Neurontin and Geodon might require a period of adjustment; thus immediate effects might not be noticeable.
The side effect profiles differ between these two drugs. While generally well-tolerated, possible common side effects include dizziness or sleepiness with Neurontin while Geodon could cause restlessness or weight gain among others. For all users of either drug it's important to monitor changes especially when initiating therapy – if you notice worsening symptoms or develop suicidal ideation reach out immediately to your healthcare provider.
