Prozac vs Valium

Listen to the article instead of reading through it.


For patients suffering from major depressive disorder (MDD) or other forms of anxiety disorders, certain medications can help regulate the levels of compounds in the brain associated with mood, known as neurotransmitters. These can be instrumental in stabilizing extreme lows and managing symptoms. Prozac and Valium are two such drugs frequently prescribed for these conditions. Each affects different neurotransmitters in the brain but both contribute to mood stabilization in patients dealing with depression or anxiety disorders. Prozac functions as a selective serotonin-reuptake inhibitor (SSRI), influencing serotonin levels primarily. On the other hand, Valium is classified as a benzodiazepine which enhances the effect of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits activity in the brain, reducing fear and anxiety.

What is Prozac?

Diazepam (the generic name for Valium) is a member of the benzodiazepine class of drugs, which are known primarily as anti-anxiety medications. Diazepam was first approved by the FDA in 1963. It works by enhancing the effect of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits activity in the brain, effectively reducing anxiety and producing a calming effect. Valium is prescribed for several conditions including anxiety disorders, alcohol withdrawal symptoms, muscle spasms, or to induce sedation before medical procedures. Unlike Prozac which selectively influences serotonin with only minor influence on dopamine and norepinephrine resulting in fewer side effects; diazepam has broad effects across multiple neurotransmitters but especially GABA receptors leading to potential for more pronounced side effects such as drowsiness or physical dependence.

What conditions is Prozac approved to treat?

Valium is approved for the treatment of various conditions, including:

  • Anxiety disorders
  • Acute alcohol withdrawal symptoms
  • Adjunctive treatment for seizures
  • Preoperative relief of anxiety and tension in patients undergoing surgical procedures

How does Prozac help with these illnesses?

Valium, also known as diazepam, helps to manage anxiety by enhancing the activity of GABA, a neurotransmitter in the brain. It does this by binding to GABA receptors and facilitating their inhibition of nerve impulses. Gamma-Aminobutyric acid (GABA) is a chemical that acts as a messenger in the brain and throughout the body, playing an important role in reducing neuronal excitability, promoting relaxation and sleep. Individuals with high levels of anxiety often have unbalanced neural activity in certain parts of their brains. Therefore, by boosting GABA's inhibitory effects on these neurons, Valium can limit anxious feelings and help patients effectively manage their condition.

What is Valium?

Valium is a brand name for diazepam, which is a benzodiazepine medication. Diazepam works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA), resulting in sedative, anti-anxiety and muscle-relaxing effects. Valium was first approved by the FDA in 1963.

Unlike Prozac, an SSRI antidepressant that inhibits serotonin reuptake, Valium does not act on serotonin levels but primarily focuses on GABA regulation to induce its calming effect. This difference means that Valium's side-effect profile can be different from that of SSRIs like Prozac; it has known potential for abuse and dependency if used long-term or at high doses.

While often prescribed for anxiety disorders and symptoms of alcohol withdrawal, Valium may also be beneficial for patients with sleep issues due to its sedating properties – something not typical of drugs like Prozac. However, caution should always be taken when considering treatment options as both have their own set of considerations such as possible interactions with other drugs and withdrawal symptoms upon discontinuation.

What conditions is Valium approved to treat?

Valium is approved for the treatment of:

  • Anxiety disorders, where it helps to relieve symptoms of acute anxiety and tension
  • Alcohol withdrawal symptoms, such as severe agitation and tremors
  • Muscle spasms related to conditions like cerebral palsy or paraplegia
  • Seizures when used in combination with other treatments It's important to note that while Valium can be very effective, it should only be used under strict medical supervision due to its potential for dependence and withdrawal effects.

How does Valium help with these illnesses?

GABA (gamma-aminobutyric acid) is a neurotransmitter that inhibits or reduces the activity of nerve cells within the brain, and plays key roles in behavior, cognition, and the body's response to stress. Research suggests that GABA also helps control fear and anxiety when neurons become overexcited. Valium works by enhancing the effects of GABA in the brain, thereby producing a calming effect. Its action on this inhibitory system may play roles in Valium's effectiveness as an anti-anxiety medication and muscle relaxant. This makes it particularly useful for conditions where overexcitation leads to restlessness, insomnia, nervousness and seizures. Since it does not work primarily by altering serotonin levels like Prozac (a typical SSRI antidepressant), it can sometimes be prescribed when a patient does not respond well to SSRIs alone or may be combined with them for more comprehensive treatment.

How effective are both Prozac and Valium?

Both fluoxetine (Prozac) and diazepam (Valium) have established histories of success in treating patients with a variety of conditions, although they act on different neurotransmitters and therefore may be prescribed under different circumstances. Fluoxetine is primarily used for depression, while diazepam is often employed to manage anxiety disorders, muscle spasms, seizures or alcohol withdrawal symptoms.

The effectiveness of fluoxetine in managing depression has been widely studied since its introduction by the FDA in 1987. A prominent meta-analysis review from 2004 demonstrated that fluoxetine effectively alleviates symptoms of depression starting from the first week of treatment and has a favorable side effect profile over many other antidepressants. It also reported that it was well-tolerated even in elderly and pregnant populations due to its safety profile. Further studies showed optimal efficacy at doses around 20 mg/day and suggested benefits beyond reducing depressive symptoms, such as mitigating suicidal ideation and behavior.

Diazepam's role as an effective agent for anxiety management was recognized soon after its approval by the FDA in 1963. A comprehensive review from 2012 confirmed diazepam's efficacy not only against placebo but also when compared with other common anti-anxiety medications. However, long-term use can result in dependency issues due to its potential addictive qualities; hence it is usually recommended for short-term relief up to two weeks or so unless specifically directed otherwise by a healthcare provider.

In conclusion, both drugs serve their respective roles efficiently within their therapeutic areas - Prozac being one among the most widely-prescribed antidepressant worldwide while Valium provides significant relief across various indications including anxiety disorders.

At what dose is Prozac typically prescribed?

Oral dosages of Valium typically range from 2–10 mg taken 2 to 4 times daily, depending on the severity of symptoms. The dosage may be increased gradually as needed and tolerated, but it is important not to exceed the recommended dose. For anxiety disorders in adults, the usual starting dose is between 2 mg and 10 mg two to four times daily. Children's doses are typically lower and must always be determined by a healthcare provider based on age and weight. Just like with Prozac, it can take several weeks before seeing full therapeutic effects; however, unlike Prozac which is an antidepressant for long-term treatment of depression, Valium is commonly used for short-term relief of acute symptoms such as severe anxiety episodes or help with sleep during times of high stress.

At what dose is Valium typically prescribed?

Valium treatment typically commences at a dosage of 2-10 mg two to four times per day, depending on the severity of symptoms. The dosage can then be adjusted as needed and tolerated, but it should not exceed 40 mg in one day. For more severe disorders, such as those related to alcohol withdrawal, doses may reach up to 20 mg three or four times daily initially. However, this must always be under close medical supervision. It's essential to remember that long-term use of Valium can lead to dependence; hence it is crucial for the dose reduction process to be gradual and closely monitored by a healthcare professional.

What are the most common side effects for Prozac?

Common side effects of Valium include:

  • Drowsiness, fatigue or lethargy
  • Muscle weakness
  • Ataxia (lack of muscle control during voluntary movements)
  • Depression
  • Confusion
  • Constipation or diarrhea
  • Nausea
  • Decreased libido (sex drive)
  • Skin rash, itching or inflammation
  • Dry mouth or excessive saliva production
  • Changes in appetite and weight fluctuation -Incontinence or changes in urination pattern. If you experience any severe symptoms such as extreme drowsiness, slow reflexes, fainting, respiratory depression etc., seek immediate medical attention.

Are there any potential serious side effects for Prozac?

Valium, also known as diazepam, can lead to a number of serious side effects in rare cases:

  • Thoughts about self-harm or suicide
  • Signs of an allergic reaction such as hives, difficulty breathing, swelling in your face or throat
  • A severe skin reaction that includes fever, sore throat, burning eyes, skin pain and a red/purple rash that blisters and peels
  • Vision changes such as blurred vision or seeing halos around lights
  • Rapid heartbeats or fluttering in your chest; sudden dizziness (as if you might pass out)
  • Hyponatremia - symptoms include headache, confusion, slurred speech, severe weakness/vomiting/loss of coordination/unsteadiness
  • Severe reactions affecting the nervous system: rigid muscles/high fever/confusion/fast or uneven heartbeats/tremors/a feeling like you might pass out.

If these signs are detected when taking Valium it is advised to get immediate medical help. It's important to remember that each person may react differently to medication. Therefore it is crucial for patients to discuss potential risks with their healthcare provider before starting on a new medication regimen.

What are the most common side effects for Valium?

Valium, while an effective treatment for anxiety and muscle spasms, can lead to:

  • Dry mouth or increased salivation
  • Drowsiness or fatigue
  • Constipation or upset stomach
  • Blurred vision
  • Sleep disturbances such as insomnia
  • Muscle weakness or lack of coordination
  • Feeling restless, irritable, agitated, hostile or confused
  • Unusual risk-taking behavior and decreased inhibitions.

In more serious cases it may cause slow heartbeat. It's also important to note that long-term use of Valium can result in dependency. If you have persistent headaches while on this medication, consult your healthcare provider immediately.

Are there any potential serious side effects for Valium?

While Valium is generally well-tolerated, it's crucial to be aware of the potential side effects that could indicate a more serious problem. Watch out for:

  • Signs of an allergic reaction such as difficulty breathing; swelling of your face, lips, tongue or throat
  • Severe drowsiness or dizziness; lack of coordination or balance
  • Unusual changes in mood or behavior including confusion and hallucinations
  • Memory problems or forgetfulness
  • Suicidal thoughts or self-harming behaviors
  • A sudden onset seizure (convulsions)
  • Persistent tremors in your hands/feet
  • Involuntary eye movements
  • Slurred speech

In case you notice any of these symptoms while taking Valium, seek medical help immediately. It's essential not to ignore these signs as they might indicate severe health complications.

Contraindications for Prozac and Valium?

Both Prozac and Valium, along with most other psychiatric medications, may exacerbate symptoms of depression or anxiety in some individuals. If you notice an increase in depressive or anxious thoughts and feelings, or a surge in suicidal ideation or behavior, please seek medical help at once.

Neither Prozac nor Valium can be taken if you are currently on medication with monoamine oxidase inhibitors (MAOIs) or have been taking them recently. Always inform your doctor about all the medicines you're on; MAOIs will require approximately 5 weeks to completely leave your system so as to prevent harmful interactions with both Prozac and Valium. It's critical that these guidelines be strictly followed due to the potential for severe drug interactions leading to Serotonin Syndrome - a potentially life threatening condition.

How much do Prozac and Valium cost?

For the brand name versions of these drugs:

  • The price of 30 capsules of Prozac (20 mg) averages about $570, which works out to approximately $19/day.
  • The price for 60 tablets of Valium (5 mg) hovers around $450, working out to roughly $15/day at a typical dose.

Thus, if you are on a higher dosage range for Prozac (i.e., 40 mg/day or higher), then brand-name Valium is less expensive on a per-day treatment basis. However, cost should not be the primary consideration in determining which drug is best suited for your medical needs.

As far as generic alternatives go:

  • Fluoxetine is available in packs from 15 up to 1000 capsules (20mg), with costs starting as low as $0.05/day when buying the largest pack upfront and typically not exceeding about $0.90/day.
  • Diazepam, the generic form of Valium, can be found in packs ranging from 10 up to several hundreds tablets (5mg). Costs start at around just over one cent per day when buying larger quantities and usually don't exceed about $0.60/day even at more typical dosages such as 2 or even three times daily intake.

Popularity of Prozac and Valium

Fluoxetine, available in brand versions such as Prozac, was prescribed to approximately 4.7 million people in the USA in 2020. In terms of SSRI (Selective Serotonin Reuptake Inhibitor) prescriptions, fluoxetine accounted for nearly 20%, while it made up less than 10% of total antidepressant prescriptions across the country. Over the past decade, fluoxetine's prevalence has remained fairly consistent.

Contrastingly, Diazepam (also known by its brand name Valium), a benzodiazepine used primarily for treating anxiety and seizure disorders but also utilized as a muscle relaxant or sedative before medical procedures, saw about 14 million prescriptions filled in the US during 2020. Considering all benzodiazepines prescribed within this period, diazepam represented roughly around one-quarter of these medications' overall prescription rate and is frequently listed among top-prescribed psychiatric drugs within its category. However, it must be noted that unlike long-term use cases with drugs like Prozac meant for chronic conditions like depression or OCD (Obsessive Compulsive Disorder), diazepam is typically employed over shorter periods due to concerns related to dependence and withdrawal.


Both Prozac (fluoxetine) and Valium (diazepam) have long-standing records of usage in patients with psychiatric conditions, and are backed by numerous clinical studies indicating their efficacy. In some instances, the drugs may be used together under careful physician supervision as they can interact. Due to their different mechanisms of action - with Prozac acting primarily on serotonin levels in the brain, while Valium is a benzodiazepine that enhances the effect of GABA, an inhibitory neurotransmitter - they tend to be prescribed for different indications. Prozac is typically a first-line treatment option for depression and various anxiety disorders, whereas Valium would usually be considered for short-term relief from severe acute symptoms of anxiety or used as an adjunctive therapy.

Both medications are available in generic form which represents significant cost savings especially for patients who must pay out-of-pocket. Both might require an adjustment period; full therapeutic effects may not appear immediately.

The side effect profiles differ between these two drugs: Prozac's common side effects include nausea, upset stomach, dry mouth or sleep problems while Valium commonly causes drowsiness or tiredness. Importantly both carry risks if stopped abruptly after prolonged use so should only be discontinued under medical supervision. For both drugs, patients must closely monitor their moods especially when starting treatment and seek immediate medical help if they notice worsening conditions or thoughts about self-harm.
