Introduction

Benzodiazepines have a sedating effect due to agonism of certain subtypes of GABA receptors in the amygdala. Studies have focused on involvement of the hypothalamic-pituitary-adrenocortical (HPA) system, glutaminergic strength, NMDA, and serotonin.

Biology of Withdrawal Effects
  1. Wichniak A, Brunner H, Ising M, Gil FP, Holsboer F, Friess E. Impaired hypothalamic-pituitary-adrenocortical (HPA) system is related to severity of benzodiazepine withdrawal in patients with depression. Psychoneuroendocrinology (2004) Oct 31;29(9):1101-8. PubMed link

This study found that benzodiazepine withdrawal may be due to disinhibiting the hypothalamic-pituitary-adrenocortical (HPA) system.

2) Song J, Shen G, Greenfield LJ, Tietz EI. Benzodiazepine withdrawal-induced glutamatergic plasticity involves up-regulation of GluR1-containing α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptors in hippocampal CA1 neurons. Journal of Pharmacology and Experimental Therapeutics (2007) Aug 1;322(2):569-81. PubMed link

Researchers found that benzodiazepine withdrawal leads to an increase in glutaminergic strength and excitability of CA1 in the brain, and that these changes can underlie the mechanism of physiological adaptations to drug withdrawal.

3) Xiang K, Tietz EI. Benzodiazepine-induced hippocampal CA1 neuron α-amino-3-hydroxy-5-methylisoxasole-4-propionic acid (AMPA) receptor plasticity linked to severity of withdrawal anxiety: differential role of voltage-gated calcium channels and N-methyl-D-aspartic acid receptors. Behavioural Pharmacology. 2007 Sep 1;18(5-6):447-60. PubMed link

These authors showed that increased AMPAR activity during benzodiazepine withdrawal contributes to anxiety experienced when people withdraw from benzodiazepines, and that NMDAR activity is downregulated. The authors speculate that increased plasticity of glutamate receptors and certain types of receptor signaling may underlie withdrawal anxiety and substance dependence.

4) Shen G, Tietz EI. Down-regulation of synaptic GluN2B subunit-containing N-methyl-D-aspartate receptors: a physiological brake on CA1 neuron α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid hyperexcitability during benzodiazepine withdrawal. Journal of Pharmacology and Experimental Therapeutics. 2011 Jan 1;336(1):265-73. PubMed link

Researchers suggest that a subtype of NMDA receptor (GluN2B) may modulate the strength of the gluteminergic synapse during benzodiazepine withdrawal (because there is neuronal hyperactivity resulting from withdrawal, which may cause anxiety), and thus may be an attempt to achieve homeostasis.

5) Benyamina A, Naassila M, Bourin M. Potential role of cortical 5-HT 2A receptors in the anxiolytic action of cyamemazine in benzodiazepine withdrawal. Psychiatry Research. 2012 Jul 30;198(2):307-12. PubMed link

This study found that the anxiety-reducing effect of cyamemazine in withdrawal from benzodiazepines is likely due to serotonin receptor antagonistic activity in the cortex.

6) Preskorn SH. A Way of Conceptualizing Benzodiazepines to Guide Clinical Use. Journal of Psychiatric Practice. 2015 Nov 1;21(6):436-41. PubMed link

This article divides benzodiazepines into 4 classes depending on their characteristics on a continuum along 2 dimensions: length of half-life and potency of affinity for the binding site (low to high) and proposes using medications for different clinical indications depending on their classification.

Animal Research

Animal research has focused on anxiety as a withdrawal symptom of benzodiazepines. Increased serotonin release is hypothesized to play a role in this increased anxiety. Sudden withdrawal from alprazolam was associated with HPA axis activation, decrease in food consumption, and decrease in body weight.

7) File SE, Pellow S. Chlordiazepoxide enhances the anxiogenic action of CGS 8216 in the social interaction test: evidence for benzodiazepine withdrawal? Pharmacology Biochemistry and Behavior. 1985 Jul 1;23(1):33-6. PubMed link

This study found that chlordiazepoxide made animals less socially interactive (a measure of increased anxiety) in the presence of a compound CGS 8216 after both acute and chronic treatment, which was a surprising finding given that it is typically anxiety-reducing. The authors speculate this effect may be due to withdrawal from the high dose.

8) Baldwin HA, Hitchcott PK, File SE. Evidence that the increased anxiety detected in the elevated plus-maze during chlordiazepoxide withdrawal is not due to enhanced noradrenergic activity. Pharmacology Biochemistry and Behavior. 1989 Dec 31;34(4):931-3. PubMed link

In this study, researchers administered chlordiazepoxide to rats and then put them in a maze 24-30 hours after the last dose. Anxiety was measured by the percentage of time rats spent in each arm of the maze. Researchers found that rats withdrawing from CDP spent less time in the open arms of the maze, indicating anxiety. Clonidine and DL-propranolol did not reverse these effects, indicating that there is likely not noradrenergic involvement in the anxiety component of benzodiazepine withdrawal.

9) Nutt DJ. Pharmacological mechanisms of benzodiazepine withdrawal. Journal of Psychiatric Research. 1990 Dec 31;24:105-10. PubMed link

This author discusses the role of receptors in benzodiazepine withdrawal, stating that a shift in efficacy occurs at different receptor sites (attenuation of agonist receptors and enhancement of inverse agonist receptors) in the brain. The author states that treatment with flumazenil has been shown in rats to prevent or reverse the efficacy shift.

This study sought to investigate whether increased release of 5-HT in the hippocampus during benzodiazepine withdrawal can be linked to anxious behaviors in animals. A group of rats who did not show an anxious response also did not have increases in 5-HT release, which corroborated the hypothesis, but the authors did not establish causality.

11) Goudie AJ, Harrison AA, Leathley MJ. Evidence for a dissociation between benzodiazepine withdrawal signs. NeuroReport. 1993 Mar 1;4(3):295-8. PubMed link

This study found that chlordiazepoxide-withdrawal-induced weight loss occurred after just 10 days of treatment, and that the severity of weight loss is proportional to the length of treatment.

The authors found that surgically castrated rats had a statistically significant weight loss when compared with rats withdrawing from benzodiazepines who were not castrated and rats not withdrawing from benzodiazepines.

13) Pokk P, Zharkovsky A. Small platform stress attenuates the anxiogenic effect of diazepam withdrawal in the plus-maze test. Behavioural Brain Research. 1998 Dec 1;97(1):153-7. PubMed link

Mice were withdrawn from benzodiazepines and then subjected to stress by standing on a small platform surrounded by water for 24 hours. These mice were then placed into a maze, as were mice who were not subjected to stress. The researchers found that benzodiazepine withdrawal induced anxiety and small platform stress inhibited anxiety; they state that the effect of stress on withdrawal symptoms thus depends on the type and length of stress.

14) Metten P, Crabbe JC. Genetic determinants of severity of acute withdrawal from diazepam in mice: commonality with ethanol and pentobarbital. Pharmacology Biochemistry and Behavior. 1999 Jul 31;63(3):473-9. PubMed link

This study found that there are likely common genetic factors contributing to seizures upon withdrawal from diazepam, ethanol, and pentobarbital. The researchers speculate that a common neural mechanism involved in actions of all three drugs are the GABA/benzodiazepine receptor/chloride ionophore complex (GRC).

15) Stock H, Ford K, Biscardi R, Wilson MA. Lack of sex differences in anxiety behaviors during precipitated benzodiazepine withdrawal in rats. Physiology & Behavior. 1999 Mar 31;66(1):125-30. PubMed link

In this study, the researchers induced benzodiazepine withdrawal with flumazenil and measured length of time spent in the open arms of a maze to ascertain anxiety. They found that rats withdrawing from benzodiazepines spent less time in the open arms of the maze, but that there was also less activity overall. The authors conclude that anxiety behaviors do not tend to increase upon precipitated withdrawal from benzodiazepines and that there is no hormonal influence.

16) Elliot EE, White JM. Precipitated and spontaneous withdrawal following administration of lorazepam but not zolpidem. Pharmacology Biochemistry and Behavior. 2000 Jun 30;66(2):361-9. PubMed link

Researchers administered Lorazepam, zolpidem, or placebo to rats for 12 days and found that there was no evidence of withdrawal syndrome in the zolpidem group despite the fact that tolerance developed, but that there was evidence of withdrawal in the lorazepam groups both after administration of flumazenil and in spontaneous cessation. However, the results of this study contradict studies in baboons and humans.

17) Nath C, Saxena RC, Gupta MB. Effect of dopamine agonists and antagonists on the lorazepam withdrawal syndrome in rats. Clinical and Experimental Pharmacology and Physiology. 2000 Mar 11;27(3):167-71. PubMed link

This study investigated the effect of dopaminergic agonists and antagonists in withdrawal from lorazepam in rats by administering these compounds to rats after withdrawing them from lorazepam and measuring withdrawal symptoms. The authors conclude that dopamine D2 receptors (and partially dopamine D1 receptors) are facilitators concerning benzodiazepine withdrawal syndrome.

18) Nath C, Gupta MB. Role of central histaminergic system in lorazepam withdrawal syndrome in rats. Pharmacology Biochemistry and Behavior. 2001 Apr 30;68(4):777-82. PubMed link

This study investigated the effect of histaminergic agonists and antagonists in withdrawal from lorazepam in rats by administering these compounds to rats after withdrawing them from lorazepam and measuring withdrawal symptoms. Histamine-N-methyl, which is an agonist of the H3 receptor, as well as the H1 receptor antagonists promethazine and pheniramine, blocked all of the withdrawal symptoms. The authors conclude that histamine H1 receptors are facilitators and H3 receptors are inhibitors concerning benzodiazepine withdrawal syndrome.

This study found that when exposed to a stimulus previously paired with an electric shock to the foot, rats that were withdrawn from benzodiazepines experienced significantly more freezing (fear conditioning) than control rats. The researchers think this could be due to depressed GABAergic activity in rats withdrawn from benzodiazepines.

This study found that sudden withdrawal from alprazolam was associated with HPA axis activation, decrease in food consumption, and decrease in body weight, as well as increased corticotropin-releasing factor mRNA expression and is likely to play a role in benzodiazepine withdrawal though the behavioral expression of this is unclear.

The authors build upon the finding that diazepam is addictive and that unlike other addictive drugs, it decreases dopamine levels, by finding that it decreases acetylcholine levels as well when administered in rats. The administration of flumazenil increases both of these neurotransmitters and shows that acetylcholine may play a role in benzodiazepine withdrawal.

22) Begg DP, Hallam KT, Norman TR. Attenuation of benzodiazepine withdrawal anxiety in the rat by serotonin antagonists. Behavioural Brain Research. 2005 Jun 20;161(2):286-90. PubMed link

This study showed that when diazepam was abruptly withdrawn, rodents developed symptoms of anxiety such as decreased social interaction and decreased exploration of open arms of a maze compared to diazepam-treated and control rodents. Administration of serotonin receptor antagonists ritanserin and mitanserin led to a reduction in these anxious behaviors in the withdrawn animals, indicating that blocking post-synaptic 5-HT2 receptors may assist in alleviating anxiety associated with benzodiazepine withdrawal.

This study investigated the effect of administering AMPA-kainate and NMDA receptor antagonists to the dorsal periaqueductal gray (dPAG) on symptoms of anxiety in rats withdrawing from benzodiazepines and found that inhibition of glutamatergic neurotransmission in the dPAG reduces symptoms of benzodiazepine withdrawal.

Researchers treated rats with diazepam for 21 days and found after abrupt cessation, rats displayed anxiety-like behaviors. They found that both flumazenil and βCCT, an antagonist selective for α 1 GABA A receptors, alleviated the anxiety symptoms. This implies that antagonism at the GABA A receptors to reduce anxiety from benzodiazepine withdrawal involves the α 1 subunits of these receptors.

Withdrawal Symptoms

Benzodiazepine withdrawal has been characterized as a distinct syndrome consisting of symptoms such as severe anxiety, heightened sensitivity, weight loss, insomnia, and perceptual changes. It is protracted in nature and may last 5-54 days. Sudden cessation of benzodiazepines may result in seizures. It is both a physical and psychological experience that may warrant care from other providers in addition to the primary care provider.

This study describes a withdrawal syndrome as benzodiazepines were withdrawn in 10 patients who stated they were unable to discontinue benzodiazepines. Symptoms included severe anxiety, heightened sensitivity, weight loss, and perceptual changes.

29) Ashton H. Benzodiazepine withdrawal: an unfinished story. British Medical Journal (Clinical research ed.). 1984 Apr 14;288(6424):1135. PubMed link

This paper outlines distinct symptoms of benzodiazepine withdrawal and describes it as being protracted in nature lasting anywhere from 5-54 days, though in some cases recovery may take six months to a year or more. The paper also describes it as a “severe illness” that is readily dismissed by medical providers as being anxiety-related, though the symptoms are distinct from anxiety.

30) Ayd FJ. Benzodiazepine Withdrawal Phenomena-New Insights. Psychiatric Annals. 1984 Feb 1;14(2):133-4.

This study reviews the results of a double-blind study of benzodiazepine withdrawal in 41 long-term benzodiazepine users conducted in Great Britain by Tyrer, Owen, and Dawling. One group consisted of early withdrawers and the other of late withdrawers. Between 44% and 50% of patients developed withdrawal symptoms included anxiety, restlessness, anorexia, low mood, depression, insomnia, and heightened sensitivity to light, touch, noise, and smell despite gradual reduction in use. After stopping, clients became more vulnerable to stress and illness, and symptoms were so distressing that 15 of 41 patients were again taking benzodiazepines at six-month follow-up and 7 were taking other psychotropic medication.

This study found in a retrospective chart review comparing older adults who discontinued benzodiazepines to older adults who continued upon discharge that discontinuers had a shorter length of stay and lower levels of depression. There was no evidence of withdrawal syndrome, though there was a non-significant trend toward increase in agitation among discontinuers.

This was a qualitative study of 41 patients who were dependent on benzodiazepines or had engaged in problematic use. They found that health concerns, feelings of being addicted, and social factors were motivations to stop and withdrawal “is difficult and unpredictable, with lots of complications.”

Protracted Withdrawal Symptoms

Studies focused on protracted withdrawal have focused on symptoms such as tinnitus, cognitive function, and life satisfaction.

This study compared treatment outcomes in people withdrawing from benzodiazepines. One group had a cognitive-behavioral intervention and the other group was treatment as usual. There were no between-group differences in outcomes, but lower initial benzodiazepine dose, zero previous attempts to withdraw, and life satisfaction predicted success in avoiding relapse.

This meta-analysis found that many benzodiazepine users show improvements in cognitive functioning after withdrawal, but that impairments compared to controls or normative data remain in most areas of cognitive functioning. There was not full restoration of cognitive functioning within the first 6 months after discontinuation and there may be aspects of cognitive functioning that are permanently impaired or take longer than 6 months to recover.

This study assessed psychosocial factors associated with relapse of benzodiazepine use after a 20-week withdrawal program. Higher dose was associated with greater numbers of withdrawal symptoms, as well as poorer outcomes. Successful withdrawal was associated with low neuroticism, low behavioral inhibition, higher numbers of positive events, and higher levels of satisfaction with social support.

The authors examined time to relapse and relapse rate among benzodiazepine users who were in a supervised taper group (Taper), a cognitive-behavioral therapy group (CBT), and a Combined group receiving both interventions. Participants in the Combined and Taper groups relapsed significantly less than those in the CBT group. Medication-free time was significantly longer for both the Taper and Combined groups than the CBT group.

This study assessed whether benzodiazepine use is associated with an acceleration in cognitive decline in adults age 65 years and older. Researchers found that chronic benzodiazepine use was associated with poorer cognitive performance, but was not associated with acceleration in cognitive decline.

Withdrawal Tapering Protocols

Different approaches to tapering benzodiazepines have been attempted: tapering (with dose equivalents for each benzodiazepine and the tapering speed provided in a table), phenobarbital substitution when more rapid detoxification is required, sedative tolerance testing in situations where estimating the dose of phenobarbital or tapering is not recommended such as an unclear history of taking sedatives, and benzodiazepine substitution. Many different medications have been tested as an assist to tapering benzodiazepines. The latest evidence, however, suggests an 8-12 week tapering schedule with the aim of complete cessation in under 6 months; schedules should be slowed if withdrawal symptoms become overly distressing, and switching to diazepam may help in some cases where the process is more difficult.

This study evaluated the use of buspirone in benzodiazepine withdrawal compared to placebo. Six of 12 patients in each group successfully withdrew, but anxiety levels were lower in those in the buspirone group. Higher benzodiazepine usage as measured by lifetime mean dose by duration was related to poorer outcome.

This study compared two different interventions to manage benzodiazepine tapering over a 4-week gradual withdrawal period: complaints management training (CMT) and anxiety management training (AMT). Though CMT was initially more successful than AMT in terms of depression, anxiety, number of severe withdrawal symptoms reported, and abstinence, at 6 months there was no significant difference between the two interventions.

This was a study of clonazepam for social phobia where after an initial 6-month period on the medication, patients were assigned to continuation therapy for 5 months or discontinuation taper of .25 mg per week every two weeks with double-blind placebo substitution. 21.1% of patients in the discontinuation group relapsed; 12.5% of patients in the continuation group and 27.7% of patients in the discontinuation group had withdrawal symptoms. At the end of the 11-month study, continuation therapy patients tapered for 3 weeks (considered “rapid”) and patients who underwent this rapid tapering showed more withdrawal symptoms than the clients who had gradually tapered.

64) Rickels K, DeMartinis N, Rynn M, Mandos L. Pharmacologic strategies for discontinuing benzodiazepine treatment. Journal of Clinical Psychopharmacology. 1999 Dec 1;19(6):12S-6S. PubMed link

This study found that a variety of medications were useful for improving the rate of tapering benzodiazepine use, but not in mitigating severity of withdrawal symptoms. This study also suggests a 4-step approach to tapering including establishing a patient-physician relationship, treat any anxiety and depression while patient is still on benzodiazepines, taper patients who are taking more than 10 mg of diazepam or equivalent only after sufficient treatment and to 10 mg per day, and then maintain this level of use for several months before final taper.

Tapering off long-term benzodiazepine use with or without group cognitive–behavioural therapy: three-condition, randomised controlled trial. The British Journal of Psychiatry. 2003 Jun 1;182(6):498-504. PubMed link

This study examined benzodiazepine taper in two groups: taper only and CBT group plus taper, and compared this to usual care. The findings were that tapering was more successful than usual care and that CBT had no added benefit and that success and intervention type had no association with measures of psychological functioning.

Randomized clinical trial of supervised tapering and cognitive behavior therapy to facilitate benzodiazepine discontinuation in older adults with chronic insomnia. American Journal of Psychiatry. 2004 Feb 1;161(2):332-42. PubMed link

This study consisted of three interventions in older adults: a supervised withdrawal taper, cognitive-behavioral therapy for insomnia, or taper plus CBT. More patients who received taper plus CBT were benzodiazepine-free at the end of the initial intervention than patients with either tapering or CBT alone, though all three groups reduced the quantity and frequency of benzodiazepine use.

The authors conducted a 21-month study of benzodiazepine craving in benzodiazepine users undergoing three interventions: a letter from their primary care provider, a supervised discontinuation involving the primary care provider combined with CBT groups, and usual care. They ound that the craving severity had decreased for all groups, patients still using benzodiazepines reported more craving than patients who had successfully quit during the study, and that the way in which patients quit benzodiazepines did not affect craving severity, though patients who received an additional tapering-off intervention reported more severe craving. This suggests that people attempting to quit benzodiazepines who are reporting a more severe craving may need more intense interventions.

This study found that, among three groups of non-depressed clients (one using SSRIs during benzodiazepine taper, one doing benzodiazepine taper without SSRIs, and one not reducing use of benzodiazepines) that the use of SSRI predicted becoming benzodiazepine-free after adjusting for age, gender, length of benzodiazepine use, and baseline HAM-A and HAM-D scores.

This was a prospective, uncontrolled, observational study of the use of pregabalin for benzodiazepine withdrawal in people age 18 and older. Success was being free of benzodiazepines according to a urine screen at 12 weeks. Though pregablin showed promise in alleviating anxiety and other withdrawal symptoms, the authors state that a placebo-controlled study should be conducted and that long-term maintenance of these results, withdrawal from pregabalin, and appropriate withdrawal schedules have yet to be investigated.

This prospective observational study examined the effectiveness of ramelteon, a melatonin receptor agonist, on insomnia related to benzodiazepine withdrawal. They found that sleep-related scores improved after beginning ramelteon and that there were no adverse-related sleep effects such as rebound insomnia that occurred with tapering of benzodiazepine hypnotics as ramelteon was used.

This study was a systematic review and meta-analysis of 10 studies of benzodiazepine withdrawal strategies in older adults. The most successful intervention was supervised withdrawal with psychotherapy and withdrawal with prescribing interventions compared to treatment as usual, education placebo, withdrawal with or without drug placebo, and psychotherapy alone. Multifaceted prescribing interventions were also significant compared to control consisting of treatment as usual or placebo.

Brain Changes

The GABAA receptors have been investigated as playing a key role in benzodiazepine dependence. Cognitive impairment compared with normative data was still present after benzodiazepine tapering among some clients, though cognitive performance improved after withdrawal.

This study found that, among 80 patients with schizophrenia or bipolar disorder, cognitive impairment compared with normative data was still present after benzodiazepine tapering, though cognitive performance improved after tapering. The addition of melatonin did not affect cognition, well-being, or psychosocial functioning.

13 COMMENTS

  1. There are so many bullshit conclusions in some of these studies.

    A lot of this is just ignorant and wrong and *dangerous*.

    The damages caused by this class of drugs remains hidden and misdiagnosed. Check out BenzoBuddies for more of a first-person experience, all ~30,000* of ’em, which isn’t worth crap to the ‘scientists’.

    There is far more than ‘anxiety’ going on.

    *How many who get caught up in the Iatrogenic Damages caused by benzodiazepines actually have access to a computer, or speak English? This ‘problem’ is vast and remains unrecognized ruining lives worldwide.

    • i am writing from iran. the psychiatrist who prescribed chlordiazepoxide 5 for over a year now is not willing to help me taper that. he also prescribed sertraline 50, and then I reduced that six months ago to 25 then within three months cut it to the current zero. I am really in need for help on how to taper chlordiaze 5 mg because he didn’t help me with that.

  2. This survey of studies show that the knowledge base on benzodiazepines is severely tainted.

    As humanbeing noted, the conclusions in many of these studies are outright dangerous.

    Benzodiazepines work on GABA-A, which is in nearly every organ in the body (if not every one). Now, imagine the profound effect that has on the body. Doctors do not give informed consent about the grave dangers inherent in this class of drugs!

  3. people if you know the strategy and procedure to withdrawal of chlordiazepoxide pls help me. ok? I really need it. I have been on chlordiaze 5 and sertraline for a year. a psychiatrist perscribed that but bow does not help me to taper. I need your help.

  4. Dear Bonnie, Hello
    please help me know how to taper chlordiazepoxide 5 mg
    I appreciate your article but I can’t read it all
    I am really in need to taper it after a year of daily consumption (along with sertraline; the pill which I managed to cut down recently to zero)
    I dread tapering chlordiazepoxide. my psychitraist didn’t help me at all for taper instructions and when i asked him to help me with it, he doubled my chlordiazepoxide up to 10 mg (which I didn’t buy from pharmacy)
    I have recently buy chlordiaze 10 mg ONLY FOR cutting that to quarters such that each quarter would be nearly 2.5 mg. so it’s two or three weeks now that I have reduced my chlordiazepoxide intake from 5 mg to 10/4 which is 2.5 mg
    🙁 there are so many pppl like me in dire situation of pain who need such help but they can’t have an outreach or they do and google to write but there is no one tto help them practically 🙁 I am so so sad about this

    I just want to tell psychiatrists “what you do is very very unfair and not humane”. you prescribe the pill but refuse to help ppl to taper

  5. What about that 55th day?

    I know you’re just reporting the studies. It’s shocking to see how inhumane and painful they are. Many of them just seek to substitute one addictive drug for another.

    THere are a few gems in here.
    18: “The authors conclude that histamine H1 receptors are facilitators and H3 receptors are inhibitors concerning benzodiazepine withdrawal syndrome.”
    40: “This author describes symptoms of the benzodiazepine withdrawal syndrome including insomnia, panic attacks, increases in anxiety, hand tremor, sweating, tension, difficulty concentrating, dry heaving and nausea, weight loss, headache, muscle tension and stiffness, perceptual changes, and seizures and psychosis at high doses. ”
    41: “This study is a case presentation of five seizures occurring after withdrawal from benzodiazepines (3% of a sample of 153 in a larger study) and found that sudden cessation and high-dose use increased risk.”
    44: attitude matters (though I disagree with the terminology): “patients reporting craving were more dependent on benzodiazepines, psychopathology, negative mood, and personality factors such as negativism, somatization, and psychopathology”
    47: “there is not currently evidence that when tapering, substitutive pharmacotherapy improves outcomes compared to gradual reduction in use.”
    49: “discontinuers had a shorter length of stay and lower levels of depression.”
    53: “many benzodiazepine users show improvements in cognitive functioning after withdrawal…There was not full restoration of cognitive functioning within the first 6 months after discontinuation and there may be aspects of cognitive functioning that are permanently impaired or take longer than 6 months to recover.”
    54: (same as 44 but with better language): “Successful withdrawal was associated with low neuroticism, low behavioral inhibition, higher numbers of positive events, and higher levels of satisfaction with social support.”
    54B: ” Participants in the Combined and Taper groups relapsed significantly less than those in the CBT group. ”
    63: “patients who underwent this rapid tapering showed more withdrawal symptoms than the clients who had gradually tapered”
    67: “tapering was more successful than usual care and that CBT had no added benefit and that success and intervention type had no association with measures of psychological functioning” So – CBT has no benefit in withdrawal! (though, that’s contradicted by 68)

    HERE’S A SHOCKING ONE:
    66: “This study had chronic benzodiazepine users switch to diazepam and found that after treatment for depression with paroxetine vs. placebo, approximately 2/3 were successful in tapering from benzodiazepines and 13% of all patients in the study remained benzodiazepine-free three years later.”

    SO – now they are addicted to PAXIL, one of the worst of the bunch!

    Confirmed by 70: “use of SSRI predicted becoming benzodiazepine-free after adjusting for age, gender, length of benzodiazepine use, and baseline HAM-A and HAM-D scores.”
    79: “melatonin does not appear to assist with cessation of benzodiazepine use.”

    Look to see greater use of SSRI, anti-seizure drugs, and neuroleptics as people try to come off these “controlled substance” drugs…
    Like this one:
    76: “Though pregablin showed promise in alleviating anxiety and other withdrawal symptoms” (at least it acknowledged that the long term risks and withdrawal plans are not addressed)

    I’m mostly summarizing these for my own references.

  6. Last year tried to taper off 1 mg of xanax 3 times a day, could not get lower than 1.25 mg in divided doses and ended up in the hospital and put on klonopin .5 mg 3 times a day ( the generic clonazepiene ) , Remeron , ( generic mirtazepiene ), and gabapentin . Off all meds but can’t stabilize at .25 mg of clonazepiene twice a day to taper further. My question is how to handle another drop which will increase burning nerve pain in spine ? I can not tolerate a return to gabapentin to treat due to side effects of that drug. My DR. does not believe a slow taper could cause this symptom or any other I have such as, severe chills , internal vibrations , lack of appetite, nausea etc. Does anyone have insight on how to survive the burning spine ? I do not have any other health issues and Neurologist agrees the issue is prescribed long term use of benzos.
    Please help as want my life back from prescribed drug no longer needed

  7. streetphotobeing ,
    Thanks for suggestions will check out. Won’t the magnesium citrate add more digestive issues as IBS has become an issue ? I also wonder does the tapering down to less then .25 mg dose only prolong the agony ? Holding over a month at .25 mgs twice a day with no stabilizing so wouldn’t another drop only cause worsening of symptoms ?
    Grateful for your insight
