Librium vs Xanax

Listen to the article instead of reading through it.


For patients with anxiety disorders or symptoms of acute alcohol withdrawal, certain drugs that enhance the effect of gamma-aminobutyric acid (GABA) in the brain can help to decrease nervous tension and manage symptoms. Librium and Xanax are two such drugs that are prescribed for these conditions. They each impact GABA receptors in the brain, but both have calming effects on patients with anxiety or withdrawal symptoms. Librium is a benzodiazepine used primarily for its sedative and anxiolytic effects, while also being effective in managing severe alcohol withdrawal symptoms. On the other hand, Xanax is also a benzodiazepine but it works more quickly and has a shorter duration of action compared to Librium; making it particularly suitable for panic disorder management.

What is Librium?

Chlordiazepoxide (the generic name for Librium) was the first drug of the benzodiazepine class, which marked a significant shift from the initial class of anti-anxiety medications known as barbiturates. Chlordiazepoxide was first approved by the FDA in 1960. Librium works by increasing levels of free gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, effectively enhancing its effects and promoting calmness and relaxation. It is prescribed primarily for anxiety disorders, alcohol withdrawal symptoms, and preoperative apprehension relief. Librium exerts selective influence on GABA receptors with only minor impact on other neurotransmitters like serotonin and dopamine, resulting in it having fewer side effects than other drugs that have stronger influences on these two other neurotransmitters.

What conditions is Librium approved to treat?

Librium is approved for treatment of a variety of conditions:

  • Anxiety disorders or short-term relief of the symptoms of anxiety
  • Withdrawal symptoms of acute alcoholism
  • Preoperative apprehension and anxiety, to calm patients before surgery

How does Librium help with these illnesses?

Librium helps to manage anxiety and withdrawal symptoms from alcohol addiction by increasing the amount of GABA, a neurotransmitter that inhibits brain activity. It does this through its action on benzodiazepine receptors which enhances the effect of GABA in your nervous system. This results in reduced anxiety, muscle relaxation and sedative effects. Similarly to serotonin in depression management, higher levels of GABA can limit the negative effects associated with anxiety disorders or acute alcohol withdrawal helping patients manage their condition more effectively.

On the other hand, Xanax also increases GABA levels but it is usually faster acting than Librium and has a shorter duration of effectiveness per dose. This makes Xanax more suitable for managing acute episodes of panic disorder whereas Librium's slower onset and longer duration may be better suited for long-term conditions such as generalized anxiety disorder or chronic alcoholism.

What is Xanax?

Xanax is a brand name for alprazolam, which is a benzodiazepine that works by enhancing the effect of gamma-aminobutyric acid (GABA) in the brain to produce sedation and reduce anxiety. It was first approved by the FDA in 1981. As Xanax enhances GABA activity rather than serotonin activity, its side-effect profile differs from that of SSRIs; it does not typically cause weight gain or sexual dysfunction but can lead to physical dependency if used long term due to its tranquilizing effect. Its strong action on GABA receptors can be beneficial for treating conditions like generalized anxiety disorders and panic disorders, especially in patients who do not respond well to typical SSRI antidepressant drugs such as Prozac. The sedating effects of Xanax are often felt more rapidly compared with those of other benzodiazepines such as Librium, making it particularly useful when rapid symptom relief is needed.

What conditions is Xanax approved to treat?

Xanax is an FDA-approved medication for the treatment of:

  • Anxiety disorders
  • Panic disorders, with or without agoraphobia (fear of places and situations that might cause panic, helplessness, or embarrassment).

How does Xanax help with these illnesses?

GABA, or gamma-aminobutyric acid, is an inhibitory neurotransmitter that plays a crucial role in reducing neuronal excitability throughout the nervous system. Its calming effect can help with symptoms of anxiety and improve sleep quality. Xanax works by enhancing the effects of GABA in the brain to promote calmness and reduce feelings of fear or anxiety. It has a quicker onset of action compared to Librium and is often prescribed for short-term relief from acute symptoms of anxiety disorders. While both medications belong to the benzodiazepine class, Xanax may be more potent but it also carries a higher risk for dependency due its rapid absorption into the bloodstream. Therefore, it's usually recommended for treatment periods not exceeding six weeks unless closely monitored by a healthcare provider.

How effective are both Librium and Xanax?

Both chlordiazepoxide (Librium) and alprazolam (Xanax) are effective benzodiazepines, with established histories of treating anxiety disorders. Librium was approved by the FDA in 1960 while Xanax was approved in 1981. They act on the same neurotransmitter, GABA, but may be prescribed under different circumstances due to their distinct pharmacokinetic profiles.

The effectiveness of Librium and Xanax in alleviating symptoms of anxiety has been directly studied; both drugs have shown efficacy in managing these symptoms as well as promising safety profiles. A study conducted demonstrated that there were no significant differences between patients receiving Librium and those receiving Xanax when measuring efficacy in treating anxiety disorder.

A review indicated that Librium is an efficient medication for reducing acute alcohol withdrawal symptoms starting from the first day of treatment, its side effect profile is favorable over many other benzodiazepines and it is well-tolerated even in elderly populations. The dose showing optimal efficacy varies greatly among individuals but usually falls within a range of 5-100 mg/day depending on severity. Beyond relieving symptoms related to alcohol withdrawal, it also seems to reduce associated agitation and tremors.

A meta-analysis indicated that Xanax appears more effective than placebo at treating panic disorder, demonstrating similar efficacy to other common benzodiazepines. Nonetheless, due to concerns about dependency risks particularly with long-term use or misuse leading potentially to addiction problems or severe withdrawal syndrome upon discontinuation after prolonged use irrespective of therapeutic doses being used during this period , shorter-acting options like Xanax are often considered only after longer-acting ones such as diazepam or clonazepam fail or are not suitable either because they can't be tolerated or contraindicated . However due its rapid onset action , alprazolam might be optimal treatment choice for those needing immediate relief from sudden surge episodes characteristic feature seen commonly among individual suffering panic attacks which typically last short duration requiring quick relief measures.

At what dose is Librium typically prescribed?

Oral dosages of Librium typically range from 5-100 mg/day, depending on the severity of symptoms and the patient's response to treatment. For mild anxiety disorders, a typical starting dose is 5-10 mg taken three or four times daily. In more severe cases, such as preoperative apprehension and anxiety, doses can be increased up to 25-100 mg/day. On the other hand, Xanax dosages usually range from .25–4 mg/day based on individual needs and responses. The usual starting dose for treating general anxiety disorder in adults is .25-.5mg taken three times a day; this may be gradually increased if needed and tolerated by the patient. As with any medication regimen, it's important that these dosages are not exceeded without consultation with a healthcare provider.

At what dose is Xanax typically prescribed?

Xanax treatment typically begins at a dosage of 0.25 to 0.5 mg taken three times daily. The dose can then be increased up to 4 mg per day, divided into several doses ideally spaced evenly throughout the day with no more than a single milligram in one dose. Maximum safe dosage is generally considered as 4 mg/day, which may be tested if there is insufficient response to treatment after several weeks or according to your doctor's advice. However, due to the potential for dependence and withdrawal symptoms, it’s crucial that any changes in dosing are done under close medical supervision.

What are the most common side effects for Librium?

Common side effects of Librium and Xanax include:

  • Drowsiness, fatigue or weakness
  • Dry mouth
  • Constipation or diarrhea
  • Changes in appetite or weight
  • Nausea, upset stomach
  • Blurred vision
  • Difficulty concentrating
  • Unsteadiness, slurred speech
  • Depression, confusion or forgetfulness
    If any of these symptoms persist while taking either Librium or Xanax, it is recommended to seek immediate medical assistance. More serious side effects such as irregular heartbeat, yellowing eyes/skin (jaundice), severe dizziness and trouble breathing can also occur although they are quite rare.

Are there any potential serious side effects for Librium?

Librium, though generally safe when used as directed, can in rare instances lead to severe side effects including:

  • Suicidal thoughts or behaviors
  • Signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
  • Vision disturbances such as blurred vision or trouble focusing.
  • Rapid heartbeat, chest pain and discomfort, shortness of breath and feeling faint.
  • Symptoms indicative of hyponatremia (low sodium levels) like headaches, confusion or disorientation, slurred speech patterns, profound weakness and fatigue accompanied by nausea and vomiting, poor coordination leading to instability while standing or walking.
  • Severe reactions involving the nervous system - muscle rigidity, hyperthermia (high fever), excessive sweating coupled with rapid heartbeats causing tremors leading to a state where passing out becomes probable.

If any signs suggestive of serotonin syndrome are noticed - restlessness/agitation, hallucinations/excessive sweating/shivering/fever/increased heart rate/ muscle stiffness/twitching/loss of coordination along with gastrointestinal symptoms like nausea/vomiting/diarrhea - immediate medical intervention is advised.

What are the most common side effects for Xanax?

The side effects of Xanax can vary and may include:

  • Dry mouth, or increased salivation
  • Blurred vision
  • Nausea, vomiting, constipation or diarrhea
  • Drowsiness, dizziness or lightheadedness
  • Changes in appetite (either loss of appetite or overeating) leading to weight changes
  • Insomnia or excessive sleeping
  • Sweating more than usual and/or trembling
  • Swelling in your hands or feet due to fluid retention
  • Muscle weakness, lack of coordination/balance problems
    -Increased frequency of urination
    -Anxiety and restlessness which might be accompanied by a fast heartbeat
    -Skin rash.

It's important to note that while some people may experience these side effects when taking Xanax, not everyone does. It's also possible for the body to adjust over time reducing the severity of these symptoms. Always consult with your healthcare provider if you are concerned about potential side effects.

Are there any potential serious side effects for Xanax?

While Xanax is often prescribed for anxiety and panic disorders, it's important to be aware of its potential side effects. In some instances, these can include:

  • Signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat
  • Hallucinations or feeling as though you might pass out
  • Depression and suicidal thoughts or actions
  • Uncontrolled muscle movements, tremors
  • Seizures (can occur after starting Xanax treatment or upon withdrawal if the medication is abruptly discontinued)
  • Rapid heartbeat/pulse and chest pain
  • Jaundice (yellowing of the skin or eyes)

If any of these symptoms occur while taking Xanax, seek medical attention immediately.

Contraindications for Librium and Xanax?

Both Librium and Xanax, along with most other benzodiazepines, may worsen symptoms of depression in some individuals. If you notice a worsening of your depression or an increase in suicidal ideation, thoughts, or behavior while taking these medications, please seek immediate medical assistance.

Neither Librium nor Xanax should be taken if you are using or have recently used opioids. Always inform your physician about the medications that you're currently on; opioids need to be carefully managed due to potential severe interactions with benzodiazepines like Librium and Xanax. These interactions can result in serious side effects such as profound sedation, respiratory distress, coma and even death.

How much do Librium and Xanax cost?

For the brand name versions of these drugs:

  • The price of 100 tablets of Librium (5 mg) averages around $400, which works out to $4–16/day, depending on your dose.
  • The price of 60 tablets of Xanax (0.25 mg) is about $725, working out to approximately $12/day.

Thus, if you are in the higher dosage range for Librium (i.e., 100 mg/day or higher), then brand-name Xanax could 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 - Chlordiazepoxide (Librium) and Alprazolam (Xanax), costs are significantly lower:

  • Chlordiazepoxide is available in packs ranging from 30 up to 90 capsules with approximate costs starting at $1.20 per day for dosages as low as 5mg per day.
  • Alprazolam comes in various pack sizes from as small as ten tablets up to hundreds and can start from as low as about $0.70/day even if taking typical doses between .25mg and .50mg twice daily.

Popularity of Librium and Xanax

Chlordiazepoxide, commonly known by its brand name Librium, is an older benzodiazepine that's been in use since the early 1960s. In the United States in 2020, it was prescribed to around a million people. Though not as frequently prescribed as other benzodiazepines, Chlordiazepoxide still accounts for approximately 2% of all prescriptions within this class of drugs.

Alprazolam, more widely recognized under its brand name Xanax, is one of the most-prescribed medications in America. In 2020 alone, it was estimated that just over 20 million people were prescribed Alprazolam. This accounted for nearly half (48%) of all benzodiazepine prescriptions and making it a highly prevalent choice among doctors and patients alike when dealing with conditions like anxiety disorders or panic attacks.


Both Librium (chlordiazepoxide) and Xanax (alprazolam) have a long-standing record of usage in the management of anxiety disorders, with numerous clinical studies indicating their effectiveness. There are cases where these drugs may be combined, but this should only be done under close supervision by a physician due to potential interactions. Both drugs act on the GABA neurotransmitter system but they tend to be prescribed under different circumstances due to differences in their pharmacokinetics and side effect profiles.

Librium is often used as a first-line option for acute alcohol withdrawal syndrome and anxiety related to surgical procedures because it has a longer half-life than Xanax. On the other hand, Xanax is more commonly prescribed for panic disorder owing to its rapid onset of action.

Both chlordiazepoxide and alprazolam are available in generic form which offers significant cost savings especially for patients who must pay out-of-pocket. The effects of both medications may not be noticeable right away as an adjustment period may be required.

The side-effect profile is similar between the two drugs; however, because alprazolam is shorter acting than chlordiazepoxide it has greater abuse potential and associated risks of withdrawal symptoms upon discontinuation. For both medications, patients need closely monitor their moods when starting treatment or adjusting dosage levels. They should seek medical help immediately if they notice worsening depression or begin having suicidal thoughts.
