Panic. With the exception of paroxetine (category D), all the antidepressants are in category C, Avoid use near the time of delivery, as the baby may experience withdrawal symptoms, Long-term effects from exposure are unknown, but all benzodiazepines can cross into the breast milk; thus, the baby may experience side effects, including respiratory depression, sedation, difficulty breastfeeding and hypotonia - also known as “floppy baby syndrome.”. * The half-life is the amount of time it takes for half of the drug to be eliminated from the body. The only medications NICE recommends for the longer term management of GAD are antidepressants. he Centers for Disease Control and Prevention recommends that doctors avoid prescribing Xanax and other benzodiazepines with opioid pain medication whenever possible. They are added as an adjunct to rest, physical therapy and / or heat and ice. [161] The various benzodiazepines differ in their toxicity; temazepam appears most toxic in overdose and when used with other drugs. 1. While BZD therapeutic effects disappear with tolerance, depression and impulsivity with high suicidal risk commonly persist. [55][56], Benzodiazepines are the preferred choice in the management of alcohol withdrawal syndrome, in particular, for the prevention and treatment of the dangerous complication of seizures and in subduing severe delirium. Short-acting compounds have a median half-life of 1–12 hours. [142] During withdrawal, fluoroquinolone-based antibiotics are best avoided if possible; they displace benzodiazepines from their binding site and reduce GABA function and, thus, may aggravate withdrawal symptoms. What Are Benzodiazepines? [146], A number of studies have drawn an association between long-term benzodiazepine use and neuro-degenerative disease, particularly Alzheimer's disease. Desmethyldiazepam has a half-life of 36–200 hours, and flurazepam, with the main active metabolite of desalkylflurazepam, with a half-life of 40–250 hours. Drowsiness, sleepiness, or dizziness are the most commonly reported side effects with this drug class. Benzodiazepines ( BZD, BDZ, BZs ), sometimes called " benzos ", are a class of depressant drugs whose core chemical structure is the fusion of a benzene ring and a diazepine ring. [208], Internationally, benzodiazepines are categorized as Schedule IV controlled drugs, apart from flunitrazepam, which is a Schedule III drug under the Convention on Psychotropic Substances. However, they should not usually be given for longer than 2–4 weeks. The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. Further well-designed research from other populations as well as a biologically plausible mechanism is required to confirm this association. Benzodiazepines are not appropriate for the long-term control of epilepsy because of the development of tolerance in a high proportion of patients. Drislane F, Garcia P, Dashe J. Convulsive status epilepticus in adults: Treatment and prognosis. 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. A1 - Kim,Paul,M.D., Ph.D. Lorazepam, oxazepam and temazepam are less likely to have this risk due to fewer liver enzyme interactions. 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. [23]: 183–189 [104], The long-term effects of benzodiazepine use can include cognitive impairment as well as affective and behavioural problems. As is the case with most drugs for which use is associated with neuroadaptation, the early phase of withdrawal typically involves two components: first, removal of the drug from the targeted neuroreceptor(s) and second, the adaptive stress response manifested by autonomic arousal. Although benzodiazepines are much safer in overdose than their predecessors, the barbiturates, they can still cause problems in overdose. [171] In terms of the mechanism of action of benzodiazepines, their similarities are too great to separate them into individual categories such as anxiolytic or hypnotic. Physical dependence on benzodiazepines, can occur after prolonged use of therapeutic doses, or even after a short treatment period in some patients. For example, lorazepam has a much shorter duration than diazepam, allowing quicker clearance of the drug and theoretically less side effects. [162][163] The symptoms of a benzodiazepine overdose may include; drowsiness, slurred speech, nystagmus, hypotension, ataxia, coma, respiratory depression, and cardiorespiratory arrest. It was prescribed by another physician who had since retired, and she insisted that it was the only thing that helped her symptoms. Benzodiazepines are a class of medications that slow down activity in your brain and nervous system. CNS depressants slow certain types of brain activity, potentially resulting in drowsiness and sedation that can be useful for individuals taking them as prescribed by a physician. In addition, some benzodiazepines are more potent than others or work for a longer length of time. anxiety, insomnia (short-term use), seizures, sedation, half-life 2.5 h (short-acting); up to 7.2 h (active metabolite), procedural sedation lasting 30 minutes or less (adults), half-life 37 to 53 minutes (short-acting), to induce relaxation and loss of memory of medical procedures or surgery, excessive anxiety for at least six months NOT due to another mental condition, medication, or substance abuse, Benzodiazepines should be used for a short period of time (usually 2 to 4 weeks) for. The following precautions can help anyone avoid unintentionally consuming a drugged drink: Benzodiazepines are among the most commonly prescribed medications. Greenblatt DJ, Shader RI, MacLeod SM, et al. Several major medical and psychiatric organizations, including the American Geriatrics Society, advise against using benzodiazepines or nonbenzodiazepine hypnotics in older adults. In a 12-month period spanning 2014 and 2015, experts estimate that at least 30.5 million people in the U.S. took benzodiazepines prescribed by a healthcare provider. *The half-life is the amount of time it takes for half of the drug to be eliminated from the body. Send scenarios to afpjournal@aafp.org. 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. [18][19] Benzodiazepines are commonly used recreationally and also often taken in combination with other addictive substances, and are controlled in most countries. Intravenous lorazepam is considered to be the first treatment of choice by many clinicians. All benzodiazepines are listed as DEA schedule IV controlled substances. The risk of dependence is increased with the agents that are rapidly absorbed and with shorter half-lives, i.e., alprazolam and diazepam. T1 - Benzodiazepines Some of their indications for use include: 2. Benzodiazepines such as diazepam or midazolam (Versed: brand discontinued) are often used. Drug treatment will depend upon the level of anxiety, patient characteristics such as age and organ function, and patient preference. For children older than 6 years of age, use 5 mg two to four times a day. When taken as prescribed and for no more than a few weeks, benzodiazepines are relatively safe and effective. Under the direction of a physician, certain benzodiazepines may be given in very serious and life-threatening situations like status epilepticus. [145], Withdrawal from long term benzodiazepines is beneficial for most individuals. Online coupons and manufacturer's patient assistance are other options. It’s also important to remember that you may not be able to taste a difference in a spiked drink. They are sometimes known as 'benzos.'. An intramuscular dose (not available in the U.S.) of 50-100 mg can be given every 4 hours if needed for alcohol withdrawal. This can be increased to 10 mg two to three times a day, Clonazepam: Safety has not been established in children, Diazepam: Start at 1 mg two to four times a day, and increase gradually as needed/tolerated, Lorazepam: Safety has not been established in children, Oxazepam: Safety has not been established for children under 6 years of age. [209], Benzodiazepines are considered major addictive substances. Benzodiazepines. [115][124], The main problem of the chronic use of benzodiazepines is the development of tolerance and dependence. [9] These reactions have been explained as consequences of disinhibition and the subsequent loss of control over socially unacceptable behavior. Increased glutamatergic activity is thought to be part of a compensatory mechanism to chronic GABAergic inhibition from benzodiazepines. Oxazepam and lorazepam are often used in patients at risk of drug accumulation, in particular, the elderly and those with cirrhosis, because they are metabolized differently from other benzodiazepines, through conjugation. Benzodiazepine and alcohol can have a synergistic interaction, leading to CNS depression and death. Lack of coordination may result in falls and injuries, in particular, in the elderly. [127], The most frequent symptoms of withdrawal from benzodiazepines are insomnia, gastric problems, tremors, agitation, fearfulness, and muscle spasms. anxiety, insomnia (short-term use), seizures, sedation, sedation, preoperative, relaxant before minor procedures. Online Internet pharmacies are increasingly a danger to patients and their health. [210] On the international scene, benzodiazepines are categorized as Schedule IV controlled drugs by the INCB, apart from flunitrazepam, which is a Schedule III drug under the Convention on Psychotropic Substances. In general, benzodiazepines should be discontinued slowly to minimize symptoms such as: Shorter-acting drugs produce a brief and more intense withdrawal reaction that usually begins within 24 hours of discontinuation. [200] Nonbenzodiazepines are molecularly distinct, but nonetheless, they work on the same benzodiazepine receptors and produce similar sedative effects. [92][93] Short to intermediate-acting benzodiazepines are preferred in the elderly such as oxazepam and temazepam. Many of the brand name products have been discontinued by their manufacturers; however, equivalent, lower-cost generics are available for these brands. "Benzodiazepines. [137] Severe symptoms usually occur as a result of abrupt or over-rapid withdrawal. Antidepressants have higher remission rates and are, in general, safe and effective in the short and long term. Anxiolytics: past, present, and future agents. Long-term use has the potential to cause both physical and psychological dependence and severe withdrawal symptoms such as depression, anxiety (often to the point of panic attacks), and agoraphobia. This slows down the nervous system and has a relaxing, sedative effect . That way, you can benefit from these medications and reduce the risk of problems along the way. At the same time, 117 general practitioners and 50 health authorities were sued by patients to recover damages for the harmful effects of dependence and withdrawal. Some researchers advocate for a prolonged schedule in which the patient can exert some control over the pacing,5 whereas others recommend a fairly rapid schedule (eight to 12 weeks), with the option to slow down if withdrawal symptoms become unmanageable.8 For some patients, tapers longer than six months may lead to too much focus on the taper process, causing further anxiety and possible worsening of long-term outcomes.6,8 Still, other patients may do much better with slower, longer tapers. Side Effects of Benzodiazepines. Nemeroff CB. Most patients can respond to verbal cues or tactile commands. Alcohol withdrawal symptoms, particularly . Paradoxical reactions, such as increased seizures in epileptics,[110] aggression, violence, impulsivity, irritability and suicidal behavior sometimes occur. US Food and Drug Administration. A patient experiencing a benzodiazepine overdose may have the following signs and symptoms: The use of flumazenil in benzodiazepine overdose is controversial and the risks may outweigh any possible benefit. The withdrawal. Benzodiazepines are a powerful class of medication used to treat anxiety, insomnia, and panic disorder. Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. According to the ICD-10, dependence is diagnosed if 3 or more of the following criteria were met in the previous year: a strong desire or compulsion to take the drug, difficulties in controlling. A major disadvantage of benzodiazepines is that tolerance to therapeutic effects develops relatively quickly while many adverse effects persist. In July 2020, remimazolam besylate (Byfavo) was approved by the FDA for the induction and maintenance of procedural sedation in adults undergoing procedures lasting 30 minutes or less. 9 In general . This strategy may allow the patient to develop self-efficacy to manage a small dose reduction without significant adverse effects and ease anxiety about further dose reductions.5 Providing anticipatory guidance about potential withdrawal symptoms, as well as encouraging the patient and reinforcing alternative strategies for stress management, are supportive interventions to incorporate before and during benzodiazepine tapers.5 Some patients may also benefit from formal psychotherapy focused on addressing any underlying psychiatric symptoms that may be unmasked by tapering.5,6, Predictive factors associated with difficult tapers include previous failed attempts, comorbid chronic psychiatric or physical illness, personality disorders, a history of alcohol or drug use, lack of family or social support, older age, and an unsympathetic primary care physician.2 Patients who receive prescriptions from their own primary care physician are more likely to successfully taper off of benzodiazepines compared with those who received a prescription from another physician,7 emphasizing the importance of physician-patient rapport and physician empathy and encouragement during tapers.5 Table 1 describes when to taper a patient's dosage of benzodiazepines.8, Abruptly discontinuing benzodiazepines after a patient has been taking them daily for more than one month is potentially dangerous; withdrawal can be severe or even life-threatening. [98] However, controversy exists as to tolerance to the anxiolytic effects with some evidence that benzodiazepines retain efficacy[125] and opposing evidence from a systematic review of the literature that tolerance frequently occurs[24][31] and some evidence that anxiety may worsen with long-term use. It can be given as an intravenous injection or a continuous intravenous infusion. Traditional benzodiazepines can be associated with overdoses and fatal consequences when combined with alcohol, opioids, other sedatives, or illicit drugs. In some areas, providers can’t prescribe these medications without first seeing you for a follow-up visit. Benzodiazepines are extensively metabolized, and the parent compounds are not detected in urine. [91] The long-term effects of benzodiazepines and benzodiazepine dependence in the elderly can resemble dementia, depression, or anxiety syndromes, and progressively worsens over time. For each subunit, many subtypes exist (α1–6, β1–3, and γ1–3). [11] Chlordiazepoxide, which also has a long half-life and long-acting active metabolites, can be used as an alternative. [39], Benzodiazepines are sometimes used in the treatment of acute anxiety, as they bring about rapid and marked relief of symptoms in most individuals;[31] however, they are not recommended beyond 2–4 weeks of use due to risks of tolerance and dependence and a lack of long-term effectiveness. For short-acting benzodiazepines, such as alprazolam, rebound symptoms may appear between doses,1 which typically leads to dose escalation with temporary relief of these symptoms,4 as in this case scenario. Copyright © 2023 American Academy of Family Physicians. Longer-acting benzodiazepines have a slower development of withdrawal symptoms that typically begin several days after discontinuation, but peak at about 7 days. [180][181] Benzodiazepines also function as weak adenosine reuptake inhibitors. Any patient taking benzodiazepines daily for longer than one month, especially persons: Older than 65 years (because of the risk of injury from falls and other cognitive adverse effects), Taking multiple benzodiazepines, benzodiazepines combined with prescribed opioids or amphetamines, or supratherapeutic dosages, With a cognitive disorder, history of traumatic brain injury, or current or history of substance use disorder, especially sedative-hypnotic or alcohol use disorder. [160], A reversal agent for benzodiazepines exists, flumazenil (Anexate). 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. The time needed to taper off of a benzodiazepine generally ranges from 4 weeks to 6 months, but can exceed a year in some circumstances. [14][23]: 183–184, Withdrawal is best managed by transferring the physically dependent patient to an equivalent dose of diazepam because it has the longest half-life of all of the benzodiazepines, is metabolised into long-acting active metabolites and is available in low-potency tablets, which can be quartered for smaller doses. Alcohol may potentiate these effects. Older adults have increased sensitivity and lowered metabolism of this drug class. Chlordiazepoxide (Librium®): The initial oral dose is 5-10 mg daily to twice a day; the dose can be increased by 5 mg daily; the usual therapeutic dose is 30-40 mg total/day, with twice daily or three times a day dosing. Because of these factors, healthcare providers use benzodiazepines cautiously. If necessary, adjust dose of alprazolam as needed, Monitor levels of digoxin, and reduce dose as needed, Adjust dose of diazepam as needed, or change to a benzodiazepine eliminated by glucuronidation, Reduce starting dose of alprazolam by 50%; adjust dose further as needed, Alprazolam, diazepam – Fosamprenavir (Lexiva), Chlordiazepoxide, clonazepam – ketoconazole, Diazepam, lorazepam – olanzapine (Zyprexa), Increased risk of cardiorespiratory depression, Avoid use of parenteral benzodiazepines and IM olanzapine, Diazepam – phenyton (Dilantin), fosphenytoin (Cerebyx), Monitor phenytoin levels, and adjust dose as needed, Reduce lorazepam starting dose by 50%; adjust dose further as needed, Alprazolam, clonazepam, diazepam – ritonavir (Norvir), Alprazolam, diazepam – saquinavir (Invirase), Increased sedative/CNS depressant effects, Monitor for sedative effects, and adjust dose of one or both as needed, Monitor for increased sedative/CNS depressant effects, Start tapentadol at 1/3 to 1/2 the usual starting dose, 1.
