Xanax vs Chlordiazepoxide

Listen to the article instead of reading through it.


For patients suffering from anxiety disorders and panic attacks, certain drugs that alter the balance of chemicals in the brain can help manage symptoms. Xanax and Chlordiazepoxide are two such medications often prescribed for these conditions. Both belong to a class of drugs known as benzodiazepines, which work by enhancing the effect of a neurotransmitter called gamma-aminobutyric acid (GABA). This results in sedative, sleep-inducing, anti-anxiety, anticonvulsant, and muscle relaxant properties.

Xanax (generic name alprazolam) is more commonly used for panic disorder or generalized anxiety disorder. It has a relatively short half-life, making it effective for immediate relief during intense episodes of anxiety or panic attacks.

On the other hand, Chlordiazepoxide is primarily used to relieve severe tension and anxiety associated with chronic illnesses or withdrawal symptoms from alcohol addiction due to its long half-life providing continuous effects over an extended period.

What is Xanax?

Alprazolam (the generic name for Xanax) is a drug from the category of benzodiazepines, which signifies a significant progression from the pioneer class of anti-anxiety medications known as barbiturates. Alprazolam was first approved by the FDA in 1981. Xanax enhances levels of free gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, by increasing its binding to receptors in the brain thus reducing excitability and evoking a calming effect. It is prescribed primarily for treating different forms of anxiety disorders and panic attacks. Xanax has potent anxiolytic, sedative-hypnotic effects with minor influence on seizure control or muscle relaxation, resulting in it having fewer side effects than other benzodiazepines that have stronger effects on these two other therapeutic uses.

Conversely, Chlordiazepoxide (first marketed as Librium) was actually the very first benzodiazepine developed and approved by FDA back in 1960s . It too increases GABA activity but differs slightly in its strength and duration of action with longer half-life compared to alprazolam making it more suitable for conditions requiring prolonged relief such as alcohol withdrawal symptoms besides being used in anxiety disorders.

What conditions is Xanax approved to treat?

Xanax is approved for the treatment of several mental health conditions:

  • Anxiety disorders
  • Panic disorder, with or without agoraphobia
  • Short term relief of symptoms of anxiety in generalized anxiety disorder

How does Xanax help with these illnesses?

Xanax, also known as alprazolam, functions by enhancing the effects of a neurotransmitter in the brain called GABA (gamma-aminobutyric acid). By doing so, it decreases abnormal excitement in the brain and produces calming effects. GABA inhibits nerve transmission in the brain, effectively calming nervous activity. Like serotonin that is involved with depression management, GABA plays an important role in mood regulation, anxiety levels and sleep patterns among other things.

Chlordiazepoxide operates similarly to Xanax but has a longer half-life which means its effect can last for extended periods. When there are heightened feelings of anxiety or stress-related disorders present in individuals they typically have lower levels of GABA. So by increasing GABA's efficacy through drugs like Xanax or Chlordiazepoxide these negative effects can be limited helping patients manage their conditions and stabilize their mood.

What is Chlordiazepoxide?

Chlordiazepoxide, often sold under the brand name Librium, is a benzodiazepine medication that acts on GABA receptors in the brain to increase their inhibitory effects and thus reduce nerve excitation. It was the first benzodiazepine to be synthesized and was approved by the FDA in 1960. Unlike alprazolam (Xanax), chlordiazepoxide is not classified as a triazolo-benzodiazepine, meaning it does not have an extra triazole ring attached to its structure. This structural difference leads to distinctive pharmacological properties: for instance, chlordiazepoxide has a longer half-life than Xanax which can provide sustained anxiety relief without needing frequent doses. Additionally, while both drugs can cause side-effects such as sedation or dizziness, certain side-effects like anterograde amnesia are less common with chlordiazepoxide compared to Xanax due to its lower potency and slower onset of action.

What conditions is Chlordiazepoxide approved to treat?

Chlordiazepoxide, an effective medication that belongs to the benzodiazepine class of drugs, is approved for the treatment of:

  • Anxiety disorders
  • Withdrawal symptoms from acute alcohol withdrawal It's important to note that while Chlordiazepoxide can be very beneficial in managing these conditions, it should always be taken under a doctor's supervision due to its potential for dependency and other side effects.

How does Chlordiazepoxide help with these illnesses?

Chlordiazepoxide is a benzodiazepine medication that operates by enhancing the effects of GABA, an inhibitory neurotransmitter in the brain. This results in reduced anxiety and tension, making it beneficial for treating disorders linked to excessive worry or stress. Like with serotonin, lower levels of GABA have been associated with anxiety and mood disorders. Chlordiazepoxide works by elevating the quantity of available GABA in your brain, thus alleviating some symptoms of these conditions. Its action might also be influenced by its effect on other neurotransmitters such as dopamine. Since it does not significantly affect norepinephrine levels, it is sometimes prescribed when a patient does not respond well to other "typical" anti-anxiety medications (like Xanax), or may be combined with those drugs for enhanced benefits.

How effective are both Xanax and Chlordiazepoxide?

Both alprazolam (Xanax) and chlordiazepoxide have a long history of effectiveness in treating anxiety disorders, receiving FDA approval in 1981 and 1960 respectively. As they both work by enhancing the effect of the neurotransmitter GABA, they are often prescribed for similar conditions but may be chosen based on specific patient needs or circumstances.

The efficacy of alprazolam and chlordiazepoxide has been studied directly in several clinical trials, with one notable double-blind trial in 1976 showing equivalent efficacy between the two drugs when used to manage symptoms of generalized anxiety disorder. In this study, there was no significant difference between patients taking either Xanax or chlordiazepoxide across various measures assessing improvement from baseline anxiety levels.

A review published in 2005 noted that while both medications were effective at managing symptoms associated with panic disorder over short periods, there might be some advantages to choosing Xanax over chlordiazepoxide due to its faster onset of action. This could make it more suitable for acute treatment situations where immediate relief is desired.

Conversely, a meta-analysis published in 2012 suggested that longer-acting benzodiazepines like Chlordiazepoxide might be preferred as first-line treatments for chronic anxiety conditions due to their lesser potential for dependence compared to shorter-acting alternatives such as Xanax. However, like all benzodiazepines, prolonged use can lead to tolerance and withdrawal issues regardless of which drug is chosen.

Overall evidence suggests that both drugs are effective at managing symptoms associated with various forms of anxiety disorders though individual patient factors will largely influence which medication is most appropriate.

At what dose is Xanax typically prescribed?

Oral dosages of Xanax range from 0.25-4 mg/day, but studies have indicated that for most adults, an initial dose of 0.5 mg three times a day is appropriate for treating anxiety disorders. Chlordiazepoxide dosing varies between individuals and conditions, with the typical adult dosage ranging from 5-100mg per day in divided doses. In either case, it's crucial to begin at the lower end of the dosage spectrum to minimize risk and monitor response before adjusting as needed under physician supervision. It's important not to exceed maximum recommended daily limits: For Xanax this is typically capped at 4mg/day (except in rare circumstances), while chlordiazepoxide should not generally exceed 100mg/day.

At what dose is Chlordiazepoxide typically prescribed?

Chlordiazepoxide treatment is typically initiated at a dosage of 5–10 mg, 3 to 4 times per day. Depending on the patient's response and tolerance, the dose can then be increased up to a maximum of 100 mg/day, divided into multiple doses throughout the day. If there is no significant improvement or if symptoms persist after a few weeks of treatment at this higher dosage level, your healthcare provider may evaluate and adjust the regime accordingly. As with any medication regimen, adherence to prescribed dosages and regular consultations with healthcare providers are crucial for effective treatment outcomes.

What are the most common side effects for Xanax?

Common side effects that you may experience while using Xanax or Chlordiazepoxide, include:

  • Drowsiness and fatigue
  • Dizziness
  • Dry mouth
  • Change in appetite leading to weight changes
  • Constipation or diarrhea
  • Decreased libido or sexual ability
  • Blurred vision
  • Slurred speech

Are there any potential serious side effects for Xanax?

While both Xanax and Chlordiazepoxide are used to treat anxiety disorders, there can be potential side effects for each. For instance:

  • A significant increase in depressive thoughts or self-harm tendencies
  • Signs of a major allergic reaction such as hives; difficulty breathing; swelling in your face, lips, tongue, or throat
  • Changes in vision clarity like blurred vision; seeing double images or halos around lights
  • Cardiac issues including rapid heartbeats, chest fluttering sensation, breathlessness and sudden spells of dizziness that might make you feel faint; low sodium levels - signs include headache, confusion due to slurred speech patterns severe weakness leading to vomiting with loss of coordination making the person unsteady on their feet
  • Severe reactions impacting the nervous system could entail muscle stiffness (rigidity), high fever bouts accompanied by sweating profusely and tremors. This might cause uneven fast heart beats giving rise to a feeling of passing out.
  • Symptoms indicating serotonin syndrome: agitation bouts followed by hallucinations with increased body temperature i.e., fever along with excessive perspiration (sweating). Muscle stiffness coupled with twitching movements resulting in loss of bodily movement coordination often leads to nausea inducing vomiting episodes or diarrhea.

If any such symptoms appear after taking either Xanax or Chlordiazepoxide it is advised that one should seek immediate medical attention.

What are the most common side effects for Chlordiazepoxide?

Chlordiazepoxide can cause some side effects that may require medical attention. These include:

  • Dry mouth or sore throat
  • Dizziness, lightheadedness, fainting
  • Confusion or problems with coordination
  • Unusual tiredness or weakness
  • Changes in behavior such as aggression, agitation, and mood swings.
  • Nausea, vomiting or stomach upset
  • Blurred vision
    -Muscle cramps or joint pain -Increased urination -Rash

Remember to consult your doctor if you experience these symptoms while taking chlordiazepoxide. It's also important to note that each individual might react differently to the medication; thus what works best for one person may not be the same for another. Always discuss options thoroughly with your healthcare provider before making a decision about any prescribed medication.

Are there any potential serious side effects for Chlordiazepoxide?

While Chlordiazepoxide is generally well-tolerated, it can occasionally cause severe side effects. Some of the symptoms to watch out for include:

  • Signs of an allergic reaction: skin rash or hives, difficulty breathing, swelling in your face or throat.
  • Behavioral changes such as aggression, agitation, and hallucinations.
  • Unusual risk-taking behavior and thoughts about self-harm or suicide.
  • Jaundice (yellowing of the skin or eyes).
  • Severe drowsiness with slow heart rate and weak pulse; fainting.
  • A sudden restless feeling like you need to move around (akathisia).

If any of these symptoms occur while taking Chlordiazepoxide, discontinue use immediately and seek medical attention right away.

Contraindications for Xanax and Chlordiazepoxide?

Both Xanax and Chlordiazepoxide, like most other benzodiazepines, may intensify feelings of depression in some individuals. If you notice your mental health deteriorating or an increase in suicidal ideation, thoughts, or behavior while taking these medications, please seek immediate medical help.

Neither Xanax nor Chlordiazepoxide should be taken if you are consuming or have recently consumed opioid drugs due to the risk of severe respiratory problems and even death. Always inform your physician about all the medications you have been taking; opioids will require a careful tapering strategy under medical supervision to safely stop their use before starting treatment with either Xanax or Chlordiazepoxide.

How much do Xanax and Chlordiazepoxide cost?

For the brand name versions of these drugs:

  • The price for 60 tablets of Xanax (0.25 mg) averages around $400, which works out to about $13–26/day, depending on your dose.
  • The price for 30 capsules of Chlordiazepoxide (10 mg) averages at about $80, working out to approximately $2.67/day.

Thus, if you are in the higher dosage range for Xanax (i.e., 1 mg/day or higher), then brand-name Chlordiazepoxide 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 alprazolam and chlordiazepoxide, costs are significantly lower:

  • Alprazolam (0.25mg tablets) is available in packs from 60 capsules and above with approximate costs ranging from as low as $0.07 to up to $.36 per day based upon dosages varying between .25mg daily up towards maximums of two milligram per day.
  • Chlordiazepoxide can be obtained in packages starting from quantities as small as fifteen capsules all the way up towards counts reaching into four digits like one thousand units each containing five milligrams with prices fluctuating between being nearly free at just $.01 each single day when purchasing larger bulks upfront or it could escalate upwards until close by only slightly under one dollar every single day ($.90).

Popularity of Xanax and Chlordiazepoxide

Alprazolam, under the brand name Xanax, is one of the most commonly prescribed medications for anxiety and panic disorders in the United States. In 2020, it was estimated that about 5 million people were prescribed alprazolam. Alprazolam accounted for about 17% of benzodiazepine prescriptions in the US. Its popularity has been consistent over the past decade.

Chlordiazepoxide, a first-generation benzodiazepine often marketed as Librium, was also used widely but less so than Alprazolam. It was estimated to have been prescribed to around 1 million people in USA in 2020. Chlordiazepoxide accounts for just under 4% of overall benzodiazepine prescriptions. Unlike newer drugs like alprazolam, chlordiazepoxide's use has gradually declined over recent years due to its longer half-life and associated side effects.


Both Xanax (alprazolam) and Chlordiazepoxide are long-standing, widely used benzodiazepines for the treatment of anxiety disorders. They have been backed by numerous clinical studies indicating that they are more effective than placebo treatments. Occasionally, these drugs may be combined or used interchangeably depending on patient tolerance and symptom severity; however, this should only occur under close supervision from a healthcare provider due to potential additive sedative effects.

Xanax is often preferred for its rapid onset of action which makes it highly effective at quickly alleviating acute symptoms of panic disorder, while Chlordiazepoxide has a slower onset but longer duration of action making it more suitable for chronic anxiety conditions and alcohol withdrawal.

Like Prozac and Wellbutrin in the original paragraph, both medications come as generic formulations representing significant cost savings especially for patients who must pay out-of-pocket. Both Xanax and Chlordiazepoxide may require an adjustment period as their full therapeutic benefits might not be noticeable immediately.

The side effect profiles between these two drugs are similar with typical benzodiazepine side effects such as drowsiness, confusion, amnesia being common in both. However, Xanax has been associated with higher rates of dependency compared to chlordiazepoxide due to its faster half-life necessitating frequent dosing schedules leading to roller-coaster plasma levels. As with all medications affecting mental health like antidepressants mentioned earlier , patients initiating therapy must closely monitor their moods or any changes thereof and seek immediate medical assistance if they notice worsening depression or thoughts about self-harm.
