Seroquel vs Geodon

Listen to the article instead of reading through it.


For patients with bipolar disorder or schizophrenia, certain drugs that adjust the levels of neurotransmitters in the brain can help stabilize mood swings and manage symptoms. Seroquel and Geodon are two such antipsychotic medications commonly prescribed for these conditions. They each impact different neurotransmitters in the brain, but both have significant effects on individuals suffering from psychotic disorders. Seroquel is an atypical antipsychotic medication that works by affecting various neurotransmitters, particularly serotonin (5HT) and dopamine (D2). On the other hand, Geodon is also classified as an atypical antipsychotic drug primarily impacting levels of serotonin (5HT2) and dopamine (D2), it's known to have less weight gain side effect compared to other drugs in its class.

What is Seroquel?

Quetiapine (the generic name for Seroquel) is an atypical antipsychotic initially approved by the FDA in 1997. It operates by modulating neurotransmitters such as dopamine and serotonin, primarily blocking specific subtypes of these receptors in the brain. This drug is usually prescribed for conditions like schizophrenia, bipolar disorder, and major depressive disorder as an adjunct treatment.

On the other hand, Ziprasidone (Geodon) was first approved by the FDA in 2001. Like Seroquel, Geodon also affects both dopamine and serotonin but has a more balanced influence on these two key neurotransmitters. Its unique receptor profile may lead to fewer side effects related to weight gain and metabolic syndrome compared to other atypical antipsychotics - advantages that might be advantageous for some patients.

However, it's worth noting that every individual's response varies depending upon their genetic makeup, co-occurring medical or psychiatric conditions, concurrent medications used along with either drug type among other factors.

What conditions is Seroquel approved to treat?

Seroquel is approved for the management of various mental health disorders, including:

  • Schizophrenia
  • Bipolar disorder (for manic and depressive episodes)
  • Adjunctive treatment of major depressive disorder (MDD) when used with antidepressants.

How does Seroquel help with these illnesses?

Seroquel functions to manage symptoms of psychiatric disorders such as schizophrenia or bipolar disorder by affecting the amount of dopamine and serotonin, two important neurotransmitters in the brain. It acts by blocking certain receptors in the brain from absorbing these chemicals, thereby maintaining higher levels for longer periods. Dopamine plays an essential role in controlling mood, memory, reward system and motor control among other things while serotonin is crucial for mood stabilization, cognition, memory and sleep patterns among others. It's believed that people with conditions like schizophrenia or bipolar disorder have imbalanced levels of these neurotransmitters which contribute to their symptoms. By increasing dopamine and serotonin levels through receptor blockage mechanism, Seroquel can limit negative effects associated with these conditions hence aiding patients manage their condition better.

What is Geodon?

Geodon, also known as ziprasidone, is an atypical antipsychotic used to treat the symptoms of schizophrenia and bipolar disorder. It works by modulating the activity of serotonin and dopamine in the brain. Geodon was first approved by the FDA in 2001 for these uses. Unlike other typical antipsychotics, it does not inhibit dopamine extensively; instead, it balances both dopamine and serotonin levels. This unique action results in a different side-effect profile compared to other typical antipsychotics such as Seroquel (quetiapine). Specifically, Geodon is less likely to cause significant weight gain—a common adverse effect with medications like Seroquel—and metabolic syndrome related issues. The modulation of both serotonin and dopamine can be beneficial for managing symptoms of schizophrenia or bipolar disorder, especially in patients who do not respond well to "typical" antipsychotic drugs such as Seroquel.

What conditions is Geodon approved to treat?

Geodon, also known by its generic name ziprasidone, is an antipsychotic medication approved for the treatment of:

How does Geodon help with these illnesses?

Dopamine is a neurotransmitter that plays vital roles in how we feel pleasure and think. It's involved in mood, attention, and regulating body movements among other functions. Low levels of dopamine have been associated with mental health disorders like depression or schizophrenia. Geodon works primarily by balancing the levels of dopamine available in the brain, thereby managing some symptoms of bipolar disorder or schizophrenia. Its action on serotonin may also play a role in its efficacy as an antipsychotic medication. Since it does not significantly increase weight as much as Seroquel does - another widely prescribed atypical antipsychotic - it can be a preferred choice for patients who are concerned about this side effect or have co-existing physical health issues such as diabetes or heart disease where weight gain could exacerbate these conditions.

How effective are both Seroquel and Geodon?

Both quetiapine (Seroquel) and ziprasidone (Geodon) have established histories of success in treating patients with bipolar disorder and schizophrenia, and they were initially approved by the FDA within a few years of each other. Since they act on different neurotransmitters, they may be prescribed under differing circumstances. The efficacy of Seroquel and Geodon in managing symptoms of bipolar disorder was directly studied in multiple double-blind clinical trials; both drugs exhibited similar effectiveness as well as promising safety profiles.

A 2007 meta-analysis demonstrated that Seroquel is effective at reducing manic episodes starting from the first week of treatment, its side-effect profile is comparable to many other antipsychotics, and it's generally well-tolerated even for long term use. The study also revealed that Seroquel has become one of the most-prescribed atypical antipsychotic drugs worldwide due to its broad spectrum activity against both positive and negative symptoms associated with mental disorders like schizophrenia or bipolar disorder.

On the other hand, a 2013 review indicated that Geodon seems to be more effective than placebo in treating acute mania related to bipolar disorder while having fewer metabolic side effects compared to other second-generation antipsychotics making it an attractive option for patients who are at risk for metabolic syndrome. Despite this advantage, Geodon is typically considered after trying first-line treatments due its risk causing cardiac arrhythmias. Nonetheless, due to its unique pharmacology - being a serotonin-dopamine antagonists with less weight gain potential- , Geodon may be an optimal treatment choice for patients who did not respond well to initial therapy or have particular needs such as those prone to obesity or diabetes.

At what dose is Seroquel typically prescribed?

Oral dosages of Seroquel for the treatment of schizophrenia range from 150–800 mg/day, yet studies have shown that a dosage around 150-300 mg/day is generally effective for most patients. For adolescents (13-17 years), they may be started on 50 mg/day. In either population, the dosage can be increased gradually over several days based on response and tolerability. The maximum dosage that should not be exceeded in any case is 800 mg/day. Conversely, Geodon dosages are typically lower; adults with schizophrenia usually start with an oral dose of 20mg twice daily while adolescents may receive half this amount to begin with, but like Seroquel it can also be adjusted according to patient’s response and tolerance levels.

At what dose is Geodon typically prescribed?

Geodon treatment typically commences with a dosage of 20 mg taken twice daily. The dose can subsequently be increased to 60-80 mg/day, divided into two doses, spaced approximately 12 hours apart. The maximum dose is up to 160 mg per day split into two doses of around 80 mg each and separated by about a 12-hour interval, which may be considered if there is no response to the initial treatment after several weeks. As always, any change in medication or dosage should only be done under the guidance and supervision of your healthcare provider.

What are the most common side effects for Seroquel?

Some of the common side effects that may occur when taking Seroquel compared to Geodon include:

  • Drowsiness or somnolence
  • Dry mouth
  • Constipation
  • Increased appetite
  • Upset stomach, nausea, vomiting
  • Weight gain (a significant difference from Geodon)
  • Fatigue, asthenia (general weakness and fatigue)
  • Nasal congestion
  • Increased liver enzyme levels in blood tests.

Geodon has its own set of potential side effects including restlessness or nervousness, muscle stiffness or spasms, tremor, skin rash and minor weight gain. Both medications could potentially cause changes in libido. It is important to discuss with your healthcare provider about these possible side effects before making a decision on medication choice.

Are there any potential serious side effects for Seroquel?

Taking Seroquel or Geodon could potentially lead to some serious side effects. Seroquel, in rare cases, has been associated with:

  • Increased suicidal thoughts or actions
  • An allergic reaction that includes symptoms such as hives, difficulty breathing, swelling of your face or throat
  • Severe skin reactions like redness and peeling
  • Vision changes including blurred vision and eye pain;
  • Fast or irregular heartbeats that may result in feelings of fainting; Abnormally low sodium levels leading to headache, confusion, slurred speech, severe weakness and vomiting.

Geodon can also cause similar side effects but is more likely to be associated with a severe nervous system response - which could include rigid muscles, high fever and sweating. It might even make you feel confused with an uneven heart rate that gives the sensation of passing out. Serotonin syndrome is another potential risk when taking Geodon - agitation, hallucinations fever shivering fast heart rate muscle stiffness twitching loss of coordination nausea vomiting diarrhea are among the symptoms for this condition. If any such complications arise while using either drug it's crucially important to seek immediate medical attention.

What are the most common side effects for Geodon?

In comparison to Seroquel, Geodon is another medication used for the treatment of certain mental/mood disorders. Potential side effects associated with Geodon include:

  • Dry mouth and nasal congestion
  • Mild ringing in the ears
  • Change in vision, particularly blurred vision
  • Nausea or occasional vomiting, abdominal discomfort, changes in appetite leading to weight loss
  • Sleep disturbances like insomnia
  • Possible tremors, excessive perspiration or feelings of anxiety and nervousness
  • Increased heart rate (tachycardia)
  • Psychological reactions such as confusion or agitation; rare instances of hostility have been reported
  • Appearance of rashes on skin
  • Increase in urination frequency
    -Migraines or dizziness
    -Possible discomfort in muscles or joints.

Please note that not all patients will experience these side effects, and they may vary from person to person. Always consult with a healthcare provider for personalized medical advice.

Are there any potential serious side effects for Geodon?

While Geodon is generally considered a safe medication, it's important for patients to be aware of potential severe side effects. Some serious signs that may indicate an adverse reaction to Geodon include:

  • Allergic reactions such as hives, difficulty breathing or swallowing, swelling in your face or throat,
  • Changes in mood or behavior, including new or worsening feelings of sadness, worthlessness, guilt
  • An abnormal heart rhythm (fast or irregular heartbeat)
  • Uncontrolled muscle movements in the face (chewing movements, lip smacking)
  • A high fever with stiff muscles and rapid heartbeat; sweating profusely
  • Signs indicative of a manic episode: racing thoughts along with increased energy levels often leading to reckless behavior; feeling uncharacteristically elated/irritable/talkative; experiencing sleep disturbances.

If you experience any of these symptoms after starting on Geodon treatment immediately seek medical attention.

Contraindications for Seroquel and Geodon?

Seroquel and Geodon, similar to other antipsychotic medications, may exacerbate symptoms of depression in some people. If you observe your depression escalating or if there's an increase in suicidal thoughts or behaviors, please seek immediate medical attention.

Neither Seroquel nor Geodon should be taken if you are currently using or have recently discontinued any form of medication that prolongs the QT interval (a measure of time during the heart's electrical cycle). Always inform your doctor about all the medications you're on; drugs affecting the QT interval would require a safe period to prevent harmful interactions with Seroquel and Geodon. Some patients might also experience withdrawal symptoms when abruptly discontinuing these medicines so it is recommended to gradually reduce your dose under physician supervision.

How much do Seroquel and Geodon cost?

For the brand name versions of these drugs:

  • A prescription for 60 tablets of Seroquel (100 mg) averages around $600, which works out to between $20–40/day depending on your dose.
  • The price for 30 capsules of Geodon (20 mg) is about $680, working out to approximately $23/day.

Thus, if you are in the higher dosage range for Seroquel (i.e., 300 mg/day or higher), then brand-name Geodon could be less expensive on a per-day treatment basis. However, cost should not be a primary consideration in determining which of these medications is right for you.

For the generic versions of Seroquel (quetiapine) and Geodon (ziprasidone), costs are significantly lower:

  • Quetiapine is available in packs of 30 tablets and above with approximate costs ranging from as low as $0.10 to $1.50 per day depending on your daily dosage.
  • Ziprasidone can also be purchased at varying pack sizes starting from 15 up to several hundred capsules with prices starting from as low as about $1/day and reaching up to roughly $3/day based on typical required dosages.

Popularity of Seroquel and Geodon

Quetiapine, in generic form as well as brand names such as Seroquel, was estimated to have been prescribed to around 7.9 million people in the US in 2020. Quetiapine accounted for just over 10% of antipsychotic prescriptions in the US. However, it appears to be one of the most-common "atypical" antipsychotics (not classified as a typical or first-generation class of antipsychotics). The prescription rate of quetiapine has been increasing steadily since its approval.

On the other hand, ziprasidone - also known by its brand name Geodon - was prescribed to approximately 1.3 million people in the USA during that same year. In terms of overall antipsychotic prescriptions within the country, this medication constitutes for roughly less than 5%. While ziprasidone is also an "atypical" antipsychotic like quetiapine and shares similar usage indications including schizophrenia and bipolar disorder management; its prevalence hasn't shown significant changes over past years.


Both Seroquel (quetiapine) and Geodon (ziprasidone) have a long-standing record of usage in patients with bipolar disorder or schizophrenia, backed by numerous clinical studies indicating they are more effective than placebo treatments. In some cases, the drugs may be combined, but this is subject to careful consideration by a physician as both can impact heart rhythm. They possess different mechanisms of action: Seroquel is an antagonist primarily at serotonin 5-HT2A receptors and dopamine D2 receptors while Geodon acts on multiple neurotransmitter receptors including dopamine antagnosim.

Seroquel tends to be used more widely due to its sedative effects which could help manage insomnia often associated with these conditions. On the other hand, Geodon might be preferable for individuals who need mood stabilization without excessive sleepiness or weight gain - two common side effects associated with Seroquel.

Both medications are available in generic form providing cost savings especially for out-of-pocket payers. Both may require an adjustment period as their full therapeutic benefits might not be noticeable right away.

The side effect profile between the two varies: both being generally well-tolerated yet each one carries unique risks like potential weight gain and metabolic issues with Seroquel versus cardiac concerns with Geodon. For both drugs, patients should monitor their physical health closely when starting treatment; any significant changes should prompt immediate medical consultation.
