Drug withdrawal
Specialty Psychiatry

Drug withdrawal, drug withdrawal syndrome, or substance withdrawal syndrome, [1] is the group of symptoms that occur upon the abrupt discontinuation or decrease in the intake of pharmaceutical or recreational drugs.

Contents

In order for the symptoms of withdrawal to occur, one must have first developed a form of drug dependence. This may occur as physical dependence, psychological dependence or both. Drug dependence develops from consuming one or more substances over a period of time.

Dependence arises in a dose-dependent manner and produces withdrawal symptoms that vary with the type of drug that is consumed. For example, prolonged use of an antidepressant medication is likely to cause a rather different reaction when discontinued compared to discontinuation of an opioid, such as heroin. Withdrawal symptoms from opiates include anxiety, sweating, vomiting, and diarrhea. Alcohol withdrawal symptoms include irritability, fatigue, shaking, sweating, and nausea. Withdrawal from nicotine can cause irritability, fatigue, insomnia, headache, and difficulty concentrating. Many prescription and legal nonprescription substances can also cause withdrawal symptoms when individuals stop consuming them, even if they were taken as directed by a physician.

The route of administration, whether intravenous, intramuscular, oral or otherwise, can also play a role in determining the severity of withdrawal symptoms.[ citation needed ] There are different stages of withdrawal as well; generally, a person will start to feel bad (crash or come down), progress to feeling worse, hit a plateau, and then the symptoms begin to dissipate. However, withdrawal from certain drugs (barbiturates, benzodiazepines, alcohol, glucocorticoids) can be fatal.[ citation needed ] While it is seldom fatal to the user, withdrawal from opiates (and some other drugs) can cause miscarriage, due to fetal withdrawal. The term "cold turkey" is used to describe the sudden cessation of use of a substance and the ensuing physiologic manifestations.

The symptoms from withdrawal may be even more dramatic when the drug has masked prolonged malnutrition, disease, chronic pain, infections (common in intravenous drug use), or sleep deprivation, conditions that drug abusers often develop as a secondary consequence of the drug. When the drug is removed, these conditions may resurface and be confused with withdrawal symptoms. Genes that encode for the alpha5 nicotinic acetylcholine receptor affect nicotine and alcohol withdrawal symptoms.

Effect on homeostasis

Homeostasis is the body's ability to maintain a certain chemical equilibrium in the brain and throughout the body. For example, the function of shivering in response to cold is to produce heat maintaining internal temperature at around 37 °C (98.6 °F). Homeostasis is impacted in many ways by drug usage and withdrawal. The internal systems perpetuate homeostasis by using different counter-regulatory methods in order to create a new state of balance based on the presence of the drug in the system. [2] These methods include adapting the body's levels of neurotransmitters, hormones, and other substances present to adjust for the addition of the drug to the body. [3]

Substances

Addiction and dependence glossary [4] [5] [6]
  • addiction – a biopsychosocial disorder characterized by persistent use of drugs (including alcohol) despite substantial harm and adverse consequences
  • addictive drug – psychoactive substances that with repeated use are associated with significantly higher rates of substance use disorders, due in large part to the drug's effect on brain reward systems
  • dependence – an adaptive state associated with a withdrawal syndrome upon cessation of repeated exposure to a stimulus (e.g., drug intake)
  • drug sensitization or reverse tolerance – the escalating effect of a drug resulting from repeated administration at a given dose
  • drug withdrawal – symptoms that occur upon cessation of repeated drug use
  • physical dependence – dependence that involves persistent physical–somatic withdrawal symptoms (e.g., fatigue and delirium tremens)
  • psychological dependence – dependence socially seen as being extremely mild compared to physical dependence (e.g., with enough willpower it could be overcome)
  • reinforcing stimuli – stimuli that increase the probability of repeating behaviors paired with them
  • rewarding stimuli – stimuli that the brain interprets as intrinsically positive and desirable or as something to approach
  • sensitization – an amplified response to a stimulus resulting from repeated exposure to it
  • substance use disorder – a condition in which the use of substances leads to clinically and functionally significant impairment or distress
  • tolerance – the diminishing effect of a drug resulting from repeated administration at a given dose

Examples (and ICD-10 code) of withdrawal syndrome include:

Prescription medicine

As noted above, many drugs should not be stopped abruptly [8] without the advice and supervision of a physician, especially if the medication induces dependence or if the condition they are being used to treat is potentially dangerous and likely to return once medication is stopped, such as diabetes, asthma, heart conditions and many psychological or neurological conditions, like epilepsy, depression, hypertension, schizophrenia and psychosis. The stopping of antipsychotics in schizophrenia and psychoses needs monitoring. [9] The stopping of antidepressants for example, can lead to antidepressant discontinuation syndrome. With careful physician attention, however, medication prioritization and discontinuation can decrease costs, simplify prescription regimens, decrease risks of adverse drug events and poly-pharmacy, focus therapies where they are most effective, and prevent cost-related under-use of medications. [10]

Medication Appropriateness Tool for Comorbid Health Conditions in Dementia [11] (MATCH-D) warns that people with dementia are more likely to experience adverse effects, and to monitor carefully for withdrawal symptoms when ceasing medications for these people as they are both more likely to experience symptoms and less likely to be able to reliably report symptoms. [12]

Anti-hypertensive drugs

The latest evidence does not have evidence of an effect due to discontinuing vs continuing medications used for treating elevated blood pressure or prevention of heart disease in older adults on all-case mortality and incidence of heart attack. [13] The findings are based on low quality evidence suggesting it may be safe to stop anti-hypertensive medications. However, older adults should not stop any of their medications without talking to a healthcare professional. [13]

Benzodiazepines, colloquially called "benzos", are a class of depressant drugs whose core chemical structure is the fusion of a benzene ring and a diazepine ring. They are prescribed to treat conditions such as anxiety disorders, insomnia, and seizures. The first benzodiazepine, chlordiazepoxide (Librium), was discovered accidentally by Leo Sternbach in 1955 and was made available in 1960 by Hoffmann–La Roche, who soon followed with diazepam (Valium) in 1963. By 1977, benzodiazepines were the most prescribed medications globally; the introduction of selective serotonin reuptake inhibitors (SSRIs), among other factors, decreased rates of prescription, but they remain frequently used worldwide.

Psychopharmacology is the scientific study of the effects drugs have on mood, sensation, thinking, behavior, judgment and evaluation, and memory. It is distinguished from neuropsychopharmacology, which emphasizes the correlation between drug-induced changes in the functioning of cells in the nervous system and changes in consciousness and behavior.

Self-medication, sometime called do-it-yourself (DIY) medicine, is a human behavior in which an individual uses a substance or any exogenous influence to self-administer treatment for physical or psychological conditions, for example headaches or fatigue.

<span class="mw-page-title-main">Opioid use disorder</span> Medical condition

Opioid use disorder (OUD) is a substance use disorder characterized by cravings for opioids, continued use despite physical and/or psychological deterioration, increased tolerance with use, and withdrawal symptoms after discontinuing opioids. Opioid withdrawal symptoms include nausea, muscle aches, diarrhea, trouble sleeping, agitation, and a low mood. Addiction and dependence are important components of opioid use disorder.

Physical dependence is a physical condition caused by chronic use of a tolerance-forming drug, in which abrupt or gradual drug withdrawal causes unpleasant physical symptoms. Physical dependence can develop from low-dose therapeutic use of certain medications such as benzodiazepines, opioids, stimulants, antiepileptics and antidepressants, as well as the recreational misuse of drugs such as alcohol, opioids and benzodiazepines. The higher the dose used, the greater the duration of use, and the earlier age use began are predictive of worsened physical dependence and thus more severe withdrawal syndromes. Acute withdrawal syndromes can last days, weeks or months. Protracted withdrawal syndrome, also known as post-acute-withdrawal syndrome or "PAWS", is a low-grade continuation of some of the symptoms of acute withdrawal, typically in a remitting-relapsing pattern, often resulting in relapse and prolonged disability of a degree to preclude the possibility of lawful employment. Protracted withdrawal syndrome can last for months, years, or depending on individual factors, indefinitely. Protracted withdrawal syndrome is noted to be most often caused by benzodiazepines. To dispel the popular misassociation with addiction, physical dependence to medications is sometimes compared to dependence on insulin by persons with diabetes.

Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption of the drug. A drug addiction, a distinct concept from substance dependence, is defined as compulsive, out-of-control drug use, despite negative consequences. An addictive drug is a drug which is both rewarding and reinforcing. ΔFosB, a gene transcription factor, is now known to be a critical component and common factor in the development of virtually all forms of behavioral and drug addictions, but not dependence.

Post-acute withdrawal syndrome (PAWS) is a hypothesized set of persistent impairments that occur after withdrawal from alcohol, opiates, benzodiazepines, antidepressants, and other substances. Infants born to mothers who used substances of dependence during pregnancy may also experience a PAWS. While PAWS has been frequently reported by those withdrawing from opiate and alcohol dependence, the research has limitations. Protracted benzodiazepine withdrawal has been observed to occur in some individuals prescribed benzodiazepines.

Psychological dependence is a cognitive disorder that involves emotional–motivational withdrawal symptoms - such as anxiety or anhedonia - upon cessation of prolonged drug abuse or certain repetitive behaviors. It develops through frequent exposure to certain psychoactive substances or behaviors, which leads to an individual requiring further exposure to avoid withdrawal symptoms, as a result of negative reinforcement. Neuronal counter-adaptation is believed to play a role in generating withdrawal symptoms, which could be mediated through changes in neurotransmitter activity or altered receptor expression. Environmental enrichment and physical activity can attenuate withdrawal symptoms.

<span class="mw-page-title-main">Polysubstance dependence</span> Medical condition

Polysubstance dependence refers to a type of substance use disorder in which an individual uses at least three different classes of substances indiscriminately and does not have a favorite substance that qualifies for dependence on its own. Although any combination of three substances can be used, studies have shown that alcohol is commonly used with another substance. This is supported by one study on polysubstance use that separated participants who used multiple substances into groups based on their preferred substance. The results of a longitudinal study on substance use led the researchers to observe that excessively using or relying on one substance increased the probability of excessively using or relying on another substance.

<span class="mw-page-title-main">Benzodiazepine dependence</span> Medical condition

Benzodiazepine dependence defines a situation in which one has developed one or more of either tolerance, withdrawal symptoms, drug seeking behaviors, such as continued use despite harmful effects, and maladaptive pattern of substance use, according to the DSM-IV. In the case of benzodiazepine dependence, the continued use seems to be typically associated with the avoidance of unpleasant withdrawal reaction rather than with the pleasurable effects of the drug. Benzodiazepine dependence develops with long-term use, even at low therapeutic doses, often without the described drug seeking behavior and tolerance.

<span class="mw-page-title-main">Substance use disorder</span> Continual use of drugs (including alcohol) despite detrimental consequences

Substance use disorder (SUD) is the persistent use of drugs despite the substantial harm and adverse consequences to one's own self and others, as a result of their use. In perspective, the effects of the wrong use of substances that are capable of causing harm to the user or others, have been extensively described in different studies using a variety of terms such as substance use problems, problematic drugs or alcohol use, and substance use disorder. The National Institute of Mental Health (NIMH) states that "Substance use disorder (SUD) is a treatable mental disorder that affects a person's brain and behavior, leading to their inability to control their use of substances like legal or illegal drugs, alcohol, or medications. Symptoms can be moderate to severe, with addiction being the most severe form of SUD". Substance use disorders (SUD) are considered to be a serious mental illness that fluctuates with the age that symptoms first start appearing in an individual, the time during which it exists and the type of substance that is used. It is not uncommon for those who have SUD to also have other mental health disorders. Substance use disorders are characterized by an array of mental/emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; operating vehicles while intoxicated; and physiological withdrawal symptoms. Drug classes that are commonly involved in SUD include: alcohol (alcoholism); cannabis; opioids; stimulants such as nicotine, cocaine and amphetamines; benzodiazepines; barbiturates; and other or unknown substances.

Neonatal withdrawal or neonatal abstinence syndrome (NAS) or neonatal opioid withdrawal syndrome (NOWS) is a withdrawal syndrome of infants after birth caused by in utero exposure to drugs of dependence, most commonly opioids. Common signs and symptoms include tremors, irritability, vomiting, diarrhea, and fever. NAS is primarily diagnosed with a detailed medication history and scoring systems. First-line treatment should begin with non-medication interventions to support neonate growth, though medication interventions may be used in certain situations.

<span class="mw-page-title-main">Addiction</span> Disorder resulting in compulsive behaviours

Addiction is a neuropsychological disorder characterized by a persistent and intense urge to use a drug or engage in a behaviour that produces natural reward, despite substantial harm and other negative consequences. Repetitive drug use often alters brain function in ways that perpetuate craving, and weakens self-control. This phenomenon – drugs reshaping brain function – has led to an understanding of addiction as a brain disorder with a complex variety of psychosocial as well as neurobiological factors that are implicated in addiction's development. Classic signs of addiction include compulsive engagement in rewarding stimuli, preoccupation with substances or behavior, and continued use despite negative consequences. Habits and patterns associated with addiction are typically characterized by immediate gratification, coupled with delayed deleterious effects.

Cannabis use disorder (CUD), also known as cannabis addiction or marijuana addiction, is a psychiatric disorder defined in the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and ICD-10 as the continued use of cannabis despite clinically significant impairment.

<span class="mw-page-title-main">Psychoactive drug</span> Chemical substance that alters nervous system function

A psychoactive drug, psychopharmaceutical, psychoactive agent, or psychotropic drug is a chemical substance that changes the function of the nervous system and results in alterations of perception, mood, cognition, and behavior. These substances may be used medically, recreationally, for spiritual reasons, or for research. Some categories of psychoactive drugs may be prescribed by physicians and other healthcare practitioners because of their therapeutic value.

<span class="mw-page-title-main">Opioid withdrawal</span> Withdrawal symptoms of opiates

Opioid withdrawal is a set of symptoms arising from the sudden withdrawal or reduction of opioids where previous usage has been heavy and prolonged. Signs and symptoms of withdrawal can include drug craving, anxiety, restless legs, nausea, vomiting, diarrhea, sweating, and an increased heart rate. Opioid use triggers a rapid adaptation in cellular signalling pathways that means, when rapidly withdrawn, there can be adverse physiological effects. All opioids, both recreational drugs and medications, when reduced or stopped, can lead to opioid withdrawal symptoms. When withdrawal symptoms are due to recreational opioid use, the term opioid use disorder is used, whereas when due to prescribed medications, the term prescription opioid use disorder is used. Opioid withdrawal can be helped by the use of opioid replacement therapy, and symptoms may be relieved by the use of medications including lofexidine and clonidine.

<span class="mw-page-title-main">Prescription drug addiction</span> Medical condition

Prescription drug addiction is the chronic, repeated use of a prescription drug in ways other than prescribed for, including using someone else’s prescription. A prescription drug is a pharmaceutical drug that may not be dispensed without a legal medical prescription. Drugs in this category are supervised due to their potential for misuse and substance use disorder. The classes of medications most commonly abused are opioids, central nervous system (CNS) depressants and central nervous stimulants. In particular, prescription opioid is most commonly abused in the form of prescription analgesics.

In medicine, tapering is the practice of gradually reducing the dosage of a medication to reduce or discontinue it. Generally, tapering is done is to avoid or minimize withdrawal symptoms that arise from neurobiological adaptation to the drug.

Despite the importance of numerous psychosocial factors, at its core, drug addiction involves a biological process: the ability of repeated exposure to a drug of abuse to induce changes in a vulnerable brain that drive the compulsive seeking and taking of drugs, and loss of control over drug use, that define a state of addiction. ... A large body of literature has demonstrated that such ΔFosB induction in D1-type [nucleus accumbens] neurons increases an animal's sensitivity to drug as well as natural rewards and promotes drug self-administration, presumably through a process of positive reinforcement ... Another ΔFosB target is cFos: as ΔFosB accumulates with repeated drug exposure it represses c-Fos and contributes to the molecular switch whereby ΔFosB is selectively induced in the chronic drug-treated state.41. ... Moreover, there is increasing evidence that, despite a range of genetic risks for addiction across the population, exposure to sufficiently high doses of a drug for long periods of time can transform someone who has relatively lower genetic loading into an addict.
