What are benzodiazepines?

Benzodiazepines are a class of medications that work in the central nervous system and are used for a variety of medical conditions, such as anxiety, seizures, and for alcohol withdrawal. Benzodiazepines appear to work by blocking excessive activity of nerves in the brain and other areas in the central nervous system. As a class, benzodiazepines are similar in how they work in the brain but have different potencies and durations of actions. Because of this, some benzodiazepines work better than others in the treatment of particular conditions. Common examples of benzodiazepines include alprazolam (Xanax), diazepam (Valium) and lorazepam (Ativan).

Common benzodiazepine uses:

  • for sleep
  • to induce relaxation and loss of memory of medical procedures or surgery
  • to reduce anxiety (anxiolytic)
  • panic disorders
  • to treat or prevent seizures
  • alcohol withdrawal treatment
  • muscle relaxant

Benzodiazepines are a large drug class and have a long history of development, starting with the first FDA-approvals in the 1960s, chloridiazepoxide (Librium) and diazepam (Valium). There are many options available within the class, and most benzodiazepines are now available generically, making them very affordable.

All benzodiazepines are listed as DEA schedule IV controlled substances. As controlled substances, all benzodiazepines have the potential for abuse, addiction and diversion.

In the past, benzodiazepines, especially when used as a sedative-hypnotic for sleep, were touted as safer alternatives to the older barbiturates, which could lead to fatal overdose, particularly when combined with alcohol. Traditional benzodiazepines taken alone are rarely associated with lethal overdoses, but when combined with other sedatives or alcohol, the risk greatly increases. Flumazenil is a benzodiazepine antagonist antidote that can be given intravenously in the emergency setting to reverse the effects of a benzodiazepine overdose.

Table 1 lists U.S. generic and brand name benzodiazepines, their common uses and duration of action. Many of the brand name products have been discontinued by their manufacturers; however, equivalent, lower-cost generics are available for these brands.

How do benzodiazepines work?

Benzodiazepines work in the central nervous system, selectively occupying certain protein areas in the brain called GABA-A receptors. There are three types of GABA (gamma-aminobutyric) receptors in the brain: GABA-A, GABA-B, and GABA-C. GABA is the main inhibitory neurotransmitter in the brain (a chemical that help to block a nerve action). GABA helps to regulate movement control, sight, anxiety, and many other brain functions.

Benzodiazepines enhance responses to the inhibitory neurotransmitter GABA by opening GABA-activated chloride channels and allowing chloride ions to enter the neuron. This action allows the neuron to become negatively charged and resistant to excitation, which leads to the various anti-anxiety, sedative, or anti-seizure activity seen with these drugs.

Common uses for benzodiazepines

Alcohol withdrawal

Alcohol withdrawal is diagnosed in a patient with a history of heavy and prolonged alcohol use and a sudden reduction or complete abstinence from alcohol. Alcohol withdrawal produces changes in the body, such as:

  • shakes or tremors
  • sleeping difficulties
  • confusion
  • anxiety
  • hallucination
  • seizures
  • delirium tremens

Medications such as benzodiazepines are a first-line treatment for acute alcohol withdrawal. Benzodiazepines reduce withdrawal symptoms and may be life-saving for the patient. Commonly used medicines in this group include: chlordiazepoxide (Librium), diazepam (Valium), and lorazepam (Ativan). Lorazepam (Ativan) or oxazepam (Serax) may be preferred in patients with liver impairment such as cirrhosis. Chlordiazepoxide, diazepam, and lorazepam can be given orally, intravenously, or intramuscularly. Oxazepam may be useful but is only available orally.


Anxiety and worry is a common problem in adults; however, when chronic, unwarranted worry lasts for a period of six months or longer and interferes with normal daily activities, this may be diagnosed as Generalized Anxiety Disorder (GAD). GAD is the most frequent anxiety disorder, affecting 6.8 million adults or about 3% of the U.S. population, but more than half remain untreated. It can be very common in older patients.

Common symptoms of GAD include:

  • excessive anxiety for at least six months NOT due to another mental condition, medication, or substance abuse
  • sleep disturbances, insomnia
  • fatigue
  • restlessness
  • difficulty concentrating
  • irritability
  • muscle tension

Drug treatment will depend upon the level of anxiety, patient characteristics such as age and organ function, and patient preference. For patients who do not want to use medications, cognitive behavioral therapy and relaxation therapy have been shown to be effective; however the combination may work best. Daily exercise has been shown to helpful for many patients with anxiety.

Antidepressants (SSRIs/SNRIs) are considered first-line therapy for most patients, and benzodiazepines may play an adjunctive role in the treatment of GAD to address acute symptoms while the antidepressant takes effect. Only short-term use of low-dose benzodiazepines (2 to 6 weeks) is recommended, with a slow, gradual tapering once the antidepressant effect takes hold. Concerns about risks of tolerance, dependence, and diversion with benzodiazepines limit their usefulness in GAD. Benzodiazepines should be avoided in patients with a history of drug abuse.

Common benzodiazepines used for GAD include alprazolam, clonazepamdiazepam, and lorazepam. Benzodiazepines should be used with extreme caution in the elderly due to the risk for excessive sedation, confusion, falls and fractures. Mirtazapine (Remeron) and buspirone (Buspar; brand discontinued) are also effective in GAD for patients who do not respond to at least two trials of SSRIs or SNRIs. Long-term use of benzodiazepines for GAD should be avoided, when possible, due to addictive risk.


The benzodiazepine hypnotics shorten the time it takes to fall asleep and prolong the sleeping period. The main differences exist in how long they might remain in the body, possibly leading to prolonged side effects. For example, lorazepam has a much shorter duration than diazepam, allowing quicker clearance of the drug and theoretically less side effects. On the other hand, diazepam can remain in the system for days and boost the risk for long-term side effects, especially in the elderly.

  • Benzodiazepines should be used for a short period of time (usually 2 to 4 weeks) for insomnia.
  • Short-acting benzodiazepines are often preferred for insomnia because they theoretically produce less next-day drowsiness, although many patients still experience these effects.
  • In general, patients should reassess their sleep habits -- avoid caffeine late in the day, limit electronics (TV, computer, mobile devices) in the bedroom and within 1-2 hours before bed, and avoiding alcohol consumption late in the evening.
  • Exercise early in the day can often help to promote a more restful sleep; however, late-night exercise might be stimulating and have the opposite effect.

The benzodiazepines that were initially FDA-approved for insomnia, such as temazepam (Restoril) or triazolam (Halcion), are not used as frequently today due to the availability of the newer nonbenzodiazepine drugs, such as eszopiclone (Lunesta), zolpidem (Ambien), or zaleplon (Sonata). All of the nonbenzodiazepine agents are approved only for the treatment of insomnia.

Muscle relaxant

The skeletal muscle relaxant class, which includes agents such as baclofen , carisoprodol (Soma), methocarbamol (Robaxin), metaxalone (Skelaxin), and cyclobenzaprine (Flexeril), are typically used first-line when a muscle-relaxing effect is needed. Benzodiazepines such as diazepam may be used short-term as muscle relaxants reducing the tone of skeletal muscle. These are generally used to relieve painful skeletal muscle spasms, such as what might occur with acute lower back pain.

Panic disorders

Panic disorder is a specific type of anxiety disorder. In the U.S., about 6 million adults, or 2.7% of the population is affected. A person with panic disorder has panic attacks which are repeated episodes of intense fear which may be expected or unexpected. These symptoms may be accompanied by physical symptoms that are similar to the body's normal response to danger, often called the "fight or flight" phenomenon. Panic attacks may accompany other mood disorders such as depression, anxiety or substance abuse conditions.

Symptoms may include:

  • rapid heart rate
  • trembling or tingling sensation
  • flushing, redness and sweating
  • shortness of breath
  • fear and heightened awareness of surroundings, even if no danger is present
  • worry about death or losing control
  • avoidance of crowds or other public spaces due to fear of impending attack (agoraphobia).

Panic disorder can be a prolonged, chronic disorder, but it is very treatable with medications that lessen symptoms. Behavioral therapy and treatment with the antidepressants such as selective serotonin-reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and/or behavioral therapy are first-line treatments. The older tricyclic antidepressants, such as nortriptyline (Pamelor) and imipramine (Tofranil) are effective, too, but may be hindered by drowsiness and anticholinergic drug side effects, which can be especially problematic for older patients. In those without co-existing conditions such as depression or a history of substance abuse, benzodiazepines may be used cautiously for a short period of time.

Benzodiazepines may be used at the beginning of therapy to lessen symptoms while the antidepressants take effect, which may take 4 to 6 weeks. Benzodiazepines such as clonazepam (Klonopin), lorazepam (Ativan), diazepam (Valium) and alprazolam (Xanax) are useful for panic attacks. They are safe when used as directed and often bring quick relief from panic symptoms. When discontinued, benzodiazepines should be slowly tapered to help avoid withdrawal symptoms like rebound insomnia and anxiety. The primary disadvantage of benzodiazepines is the risk of abuse and dependence. Selection of drug therapy should be based on issues with dosing, possible side effects or drug interactions, and cost.

Procedural sedation (also called conscious sedation)

Procedural sedation is the use of a combination of medications to help the patient relax (a sedative) and to block pain (an anesthetic) during a medical or dental procedure. Benzodiazepines such as diazepam or midazolam (Versed) are often used. This method of sedation is common for outpatient surgery or procedures that allow the patient to return home the same day, for example, endoscopy or colonoscopy procedures, wisdom tooth extractions, biopsies, and uncomplicated surgical procedures lasting less than one hour.

  • The benzodiazepines most commonly used for procedural sedation are classified by their length of action: diazepam is considered the longest acting and midazolam is short-acting. The do not impart analgesia (pain-relieving) properties.
  • Midazolam is frequently used for procedures expected to last less than one hour, and may be combined with the opiate fentanyl for pain control.
  • In the elderly or obese patients, or those with liver impairment, the sedative effect may be prolonged.

The patient may remain awake but sedated, and usually there is no recollection of the procedure. Most patients can respond to verbal cues or tactile commands. This type of sedation allows the patient to recover more quickly from anesthesia, but they will need someone to drive them home and are usually drowsy until the next day, so will need to take a full day off of work. There is normally no need to aid breathing in conscious sedation; however, a deeper level of sedation may rarely occur, therefore respiratory and resuscitative equipment should always be available to healthcare providers.


Benzodiazepines are often used in the treatment of seizures; examples include:

For most types of acute or prolonged seizures or status epilepticus, an intravenous (IV) or rectal benzodiazepine would be the treatment of first choice. Status epilepticus is considered a medical emergency in which there is either more than 30 minutes of continuous seizure activity; or there are two or more sequential seizures without recovery of full consciousness between two seizures. Intravenous lorazepam is considered to be the first treatment of choice by many clinicians; diazepam is available as a rectal gel for patients without access to an IV line; midazolam is often selected for intramuscular (IM) or oral therapy.

Buccolam is a specific form of midazolam available in the U.K., but not in the U.S. It is available as an oromucosal solution (a solution given in the side of the mouth between the cheek and gum) in prefilled syringes. Buccolam is used for the treatment of prolonged, acute, convulsive seizures in infants, toddlers, children and adolescents (from three months to less than 18 years).

Clonazepam is the benzodiazepine most frequently used for long-term control and prevention of chronic seizure disorders; however, in general benzodiazepines are not usually the first choice for seizure prevention.

  • Benzodiazepines are not appropriate for the long-term control of epilepsy because of the development of tolerance in a high proportion of patients.
  • More traditional types of seizure treatments (for example: carbamazepine, oxcarbazepine, levetiracetam, phenytoin, valproic acid, topiramate, lamotrigine) might be used first line, dependent upon patient characteristics and specific epilepsy diagnosis.

Lennox-Gastaut syndrome is a severe form of epilepsy that usually begins in early childhood and also causes developmental and behavior problems.. This form of epilepsy may involve seizures of multiple types, mental impairment, and a particular brain wave pattern. Clobazam (Onfi) is used as an add-on (adjunct) benzodiazepine anticonvulsive treatment with other seizures medications in the treatment of Lennox-Gastaut syndrome.

Common side effects of benzodiazepines

Drowsiness, sleepiness, or dizziness are the most commonly reported side effects with this drug class. Driving or operating machinery or perform other hazardous tasks can be dangerous while using these drugs. Drinking alcohol in combination with benzodiazepines may heighten these effects.

Unusual sleep behaviors and anterograde amnesia may occur with traditional benzodiazepines. Anterograde amnesia is the loss of the ability to create new memories, leading to a partial or complete inability to recall the recent past. Several benzodiazepines are known to have this powerful amnesic effect; triazolam (Halcion) is notorious.

Next day drowsiness and "hangover effect" is a concern with benzodiazepines that have long duration, for example, with diazepam or flurazepam. The sedative side effects can carry into the next day and impair driving and other daily activities; this is a particularly concerning risk in the elderly.

More recent research is focusing on the possible adverse effects on cognition (thinking and reasoning ability) in patients using benzodiazepines for long periods of time. In some patients, severe allergies like anaphylaxis and angioedema have been reported with benzodiazepines.

Related: Side Effects of Benzodiazepines

Overall, benzodiazepines should be used short-term as they can lead to tolerance, dependence (addiction) and abuse.

  • Potent benzodiazepines with shorter elimination half-lives (triazolam, alprazolam, lorazepam) may be the most prone to causing problems with tolerance and dependence.
  • Withdrawal reactions can also occur if the drug is stopped suddenly, especially those that are shorter-acting.
  • Sudden discontinuation can also lead to rebound insomnia, making sleep difficult, and leading to continued use and higher doses of benzodiazepines.
  • Discontinuation of a benzodiazepine should be done gradually under a doctor's direction.

Intravenous (IV) benzodiazepines can be associated with cardiac and/or respiratory arrest if they are given too rapidly. Other reactions due to IV administration may include:

  • hypotension (low blood pressure)
  • cardiac arrhythmias (abnormal heart rates)
  • slow heart rate
  • apnea (temporarily stopping breathing, especially during sleep)
  • respiratory depression (slowed breathing)
  • nausea/vomiting
  • blurred vision or double vision
  • skin rash
  • injection site reactions

Use in the Elderly

Some benzodiazepines (diazepam, chlordiazepoxide) have active metabolites that remain in the system for an extended period (long-acting), and this can be problematic for patients, especially older patients. Elderly patients may have liver impairment and trouble eliminating the drugs from their system. Side effects, such as dizziness, confusion or unsteadiness may persist in the elderly who are prescribed long-acting benzodiazepines.

In the elderly, benzodiazepines and nonbenzodiazepine agents should be avoided, as recommended by the Beers Criteria, an expert opinion-developed guideline addressing safe drug use in the elderly.

  • Older adults have increased sensitivity and lowered metabolism of this drug class.
  • The nonbenzodiazepine agents such as eszopiclone, zaleplon, and zolpidem (the "Z-drugs") have adverse events similar to those of benzodiazepines in older adults, such as delirium, falls and fractures but lead to minimal improvement in sleep patterns.
  • These drugs can increased emergency room visits, hospitalizations, car accidents, and their use should be avoided in older patients, also per the Beers criteria.

If there is a documented need, low doses and drugs with shorter durations (half-lives) will help to minimize side effects like dizziness, weakness, and falls that may lead to hip fractures. Under the care of a clinician, there may be appropriate uses for benzodiazepines in the elderly, such as for seizure disorders, certain sleep disorders, benzodiazepine or alcohol withdrawal, severe anxiety, procedural anesthesia, and end-of-life care.

Drug interactions with benzodiazepines

Important: Many drug interactions can occur with benzodiazepines; therefore, a drug interaction screen completed by a healthcare provider is an important step each time a new drug is added or discontinued in any treatment regimen.

Traditional benzodiazepines can be associated with overdoses and fatal consequences when combined with alcohol, opioids, other sedatives, or illicit drugs. While it is rare that an overdose of benzodiazepines by itself would be fatal, when combined with other drugs that depress the central nervous system, the risk dramatically increases.

Examples of other drugs that may be additive to the central nervous system depression if combined with benzodiazepine include:

  • phenothiazines
  • opioids
  • barbiturates
  • monoamine oxidase (MAO) inhibitors
  • antidepressants
  • alcohol
  • illicit drugs like heroin (an opiate)

Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death.

Many traditional benzodiazepines are broken down in the liver and when combined with drugs that block this action, blood levels can rise, leading to side effects. Lorazepam, oxazepam and temazepam are less likely to have this risk due to fewer liver enzyme interactions.

However, there are many other potential interactions, so a drug interaction screen with your pharmacist or doctor is needed. Patients should not stop using any medications, including benzodiazepines, without first contacting their doctor. Abrupt discontinuation of benzodiazepines may lead to severe withdrawal symptoms.

Herbal and grapefruit interactions

Herbal supplements and grapefruit can have significant interactions with certain benzodiazepines. Examples of some of the more common interactions include:

  • Kava: Combined use of kava and benzodiazepines is not recommended. A case report suggests that kava may increase the central nervous system adverse effects of benzodiazepines. In the report, a 54-year-old man treated with alprazolam became semicomatose with lethargy and disorientation following self-medication with kava for 3 days. The exact mechanism of interaction is unknown, but an additive or synergistic CNS effect is suspected. Patients on benzodiazepines should be advised to consult their caregiver before using any alternative medicines.
  • St. John’s Wort: Combined use of  St. John's wort with benzodiazepines may increase side effects such as dizziness, drowsiness, impaired thinking and difficulty concentrating. You should avoid or limit the use of alcohol while being treated with these medications. Avoid driving or operating hazardous machinery until you know how the medications affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs.
  • Grapefruit and grapefruit juice: Grapefruit and grapefruit juice may interact with certain benzodiazepines such as midazolam, triazolam, and alprazolam. Blood levels of these drugs may be increased if taken after drinking grapefruit juice and lead to potentially dangerous side effects. The proposed mechanism is CYP450 3A4 enzyme inhibition. Discuss the use of grapefruit products with your doctor. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor. Orange juice does not appear to interact with benzodiazepines.

Many benzodiazepines are broken down in the liver and may interact with drugs that also have action in the liver. For example, the 3A4 inhibitors or CYP2C19 inhibitors may lead to interactions with benzodiazepines. Some benzodiazepines such as alprazolam, chlordiazepoxide, clonazepam, and diazepam are full or partial CYP3A4 or CYP2C19 substrates, meaning they are metabolized (broken down) to some degree by one or both of these liver enzymes.

  • If benzodiazepines that are CYP3A4 or CYP2C19 substrates are used with another drug that inhibits (blocks) these enzymes, drug levels of the benzodiazepine may rise due to decreased metabolism and excretion. High drug levels mean a greater risk for side effects.
  • Either these types of drugs should be avoided with certain benzodiazepines or the benzodiazepine should be given in smaller doses; check with your doctor or pharmacist.

Examples of drugs that are considered CYP3A4 inhibitors include:

Examples of drugs that are considered CYP2C19 inhibitors include:

Benzodiazepine Use in Pregnancy and Breastfeeding


In general, benzodiazepines should NOT be used in pregnancy.

The FDA is phasing out pregnancy category risks, and instead including a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. View the pregnancy section of each individual drug monograph to determine pregnancy risk or benefit.

Benzodiazepines were previously in FDA Pregnancy Category D, meaning a positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks. Under the direction of a physician, certain benzodiazepines may be given in very serious and life-threatening situations like status epilepticus.

Breast feeding

Women who are breastfeeding their infant should not use benzodiazepines unless directed to do so by their physician. Benzodiazepines may accumulate in breast milk and in breastfed infants. Some benzodiazepines may be appropriate therapy in women who are breastfeeding, but only under the direction of a physician.

Flumazenil use as a benzodiazepine antidote

Flumazenil (Romazicon) is used to reverse the sedative effect of a benzodiazepine when used for a medical procedure and for treatment in a benzodiazepine overdose. Flumazenil blocks the central effect of benzodiazepines by competitive interaction at the benzodiazepine receptor site. A patient experiencing a benzodiazepine overdose may have the following signs and symptoms:

  • dizziness
  • inability to talk or respond
  • confusion
  • drowsiness
  • burred vision or nystagmus
  • agitation
  • weakness
  • low blood pressure
  • respiratory depression
  • hallucinations
  • coma

The use of flumazenil in benzodiazepine overdose is controversial and the risks may outweigh any possible benefit.

  • Flumazenil may be effective in reversing the sedation that occurs in a benzodiazepine overdose, but its effects on reversal of depressed breathing is less predictable.
  • Due to its short half-life, sedation and respiratory depression may recur.
  • The patient should be observed by a healthcare provider with resuscitative equipment for recurrence of sedation or respiratory depression for at least 2 hours after flumazenil administration or until the patient is stable.

Benzodiazepines are often coingested with other substances, such as opioids, in overdose. In addition, in patients who are tolerant or dependent to the effects of benzodiazepines, the use of flumazenil may precipitate severe benzodiazepine withdrawal symptoms and seizures; therefore, its use is contraindicated in these patients.

Benzodiazepine Withdrawal

Physical dependence on benzodiazepines, can occur after prolonged use of therapeutic doses, or even after a short treatment period in some patients. In general, benzodiazepines should be discontinued slowly to minimize symptoms such as:

  • sleep disturbances and rebound insomnia
  • restlessness
  • irritability
  • elevated anxiety
  • weakness
  • blurred vision
  • panic attacks
  • tremors
  • sweating/flushing
  • nausea and vomiting
  • headache
  • seizures
  • psychosis
  • hallucinations

Shorter-acting drugs produce a brief and more intense withdrawal reaction that usually begins within 24 hours of discontinuation. Longer-acting benzodiazepines have a slower development of withdrawal symptoms that typically begin several days after discontinuation, but peak at about 7 days.

The length of time required to complete a benzodiazepine withdrawal depends upon individual patient characteristics, type of benzodiazepine, ability to handle stress involved with withdrawal, and original reason for benzodiazepine use. The time need to taper a benzodiazepine generally ranges from 4 weeks to 6 months, but can exceed a year in some circumstances.

Rapid withdrawal can lead to a syndrome of severe symptoms in many patients.

  • A taper of the benzodiazepine may be accomplished by reducing the dose to no more than one quarter of the daily dose per week, with a minimum taper time of 4 weeks.
  • Withdrawal can also be managed by transferring the patient to an equivalent dose of diazepam or chlordiazepoxide, as these benzodiazepines have long half-lives and long-acting active metabolites, allowing for a smoother withdrawal process.
  • At all times, benzodiazepines should be discontinued under the care of a physician.

Costs of benzodiazepines

Most benzodiazepines are available in a generic form which can lead to cost-savings for patients. In general, benzodiazepines are used for short-term treatment, which will also cut down on expenses.

If cost is a concern for any medicine, be sure to speak to your physician when prescriptions are being written and discuss options with your pharmacist, as well. You may be able to save money on certain medications by splitting your tablets in half.

Online coupons and manufacturer's patient assistance are other options. Remember that drug prices are subject to change at any time and may differ among pharmacies. Always check with your local pharmacy for exact pricing.

Benzodiazepines used outside the U.S.

Other international benzodiazepines are available that are not approved for use in the U.S. Each generic may have multiple brand names associated with the product, and the brand names may vary between countries. Internationally available benzodiazepines have similar uses as those approved in the U.S., such as for anxiety, for sleep or sedation, use for surgical premedication, for seizures, and panic attacks. International benzodiazepines include:

Rohypnol (flunitrazepam) is an intermediate-acting benzodiazepine with general properties similar to those of Valium (diazepam). It not available legally in the U.S., although it can be found legally in other countries where it is used for the treatment of insomnia and as a pre-anesthetic. Rohypnol is used illegally to lessen the depression caused by the abuse of stimulants, such as cocaine and methamphetamine, and in cases of sexual assault where is induces memory loss in the victim. It is often referred to as the "date rape" drug.

Benzodiazepines and Online Fraud

Online Internet pharmacies are increasingly a danger to patients and their health. Fraudulent and counterfeit medications are often marketed and sold online to unsuspecting consumers. Beware of online pharmacy purchases; in general, consumers in the U.S. should only purchase medications from their local pharmacy or health-plan administered mail-order pharmacy.
