==Overview==
==Overview==
Opioid withdrawal occurs due to the cessation of opioids or the administration of an opioid antagonist following a heavy or prolonged use of opioids. Symptoms of [[withdrawal]] from opiates include, but are not limited to, [[clinical depression|depression]], aggression and irritability, leg cramps, abdominal cramps, vomiting, diarrhea, insomnia, and cravings for the [[medication|drug]] itself. Depending on the quantity, type, frequency, and duration of opioid use, the physical withdrawal symptoms last for as little as 5 days and as much as 14 days.
[[Opioid]] withdrawal occurs due to the discontinuation or reduction of [[opioid]] use in individuals with heavy and prolonged [[opioid]] use or may be precipitated by the administration of an [[opioid antagonist]] in an individual with prolonged [[opioid]] use or by the administration of an [[opioid]] [[partial agonist]] in an individual that is currently using a full [[opioid]] [[agonist]]. Symptoms of [[withdrawal]] from [[opiates]] include, but are not limited to, [[clinical depression|depression]], [[anxiety]], [[irritability]], [[leg cramps]], [[abdominal cramps]], [[Vomiting|nausea, vomiting]], [[diarrhea]], [[insomnia]], [[pain]], [[tremor]], [[rhinorrhea]], [[sweating]], and cravings for the [[medication|drug]] itself. Depending on the [[opioid]]'s [[half-life]], the [[Symptom|symptoms]] of [[opioid]] withdrawal usually resolve within 5 to 14 days, however, many patients require appropriate [[treatment]]. The [[DSM|DSM-V]] diagnostic criteria is used for the [[diagnosis]] of [[opioid]] withdrawal. The [[Medication|medications]] for treatment include [[methadone]], [[clonidine]], [[buprenorphine]], and adjunctive [[drugs]].

==Natural History, Complications and Prognosis==
==Natural History, Complications and Prognosis==
Depending on the quantity, type, frequency, and duration of opioid use, the physical withdrawal symptoms last for as little as 5 days and as much as 14 days.  The user, upon returning to the environment where they usually used opiates, can experience environmentally implied physical withdrawal symptoms well-after regaining physical homeostasis - or the termination of the physical withdrawal phase by synthesis of endogenous opioids (endorphins) and upregulation of [[opioid receptors]] to the effects of normal levels of endogenous opioids.  These implied symptoms are often just as distressing and painful as the initial withdrawal phase.


Detoxification is best conducted in an in patient facility that provides a controlled environment. Patients who are isolated and exposed solely to care givers and other patients in this environment have a better rate of staying clean then those who detox out-patient.

Overview

Opioid withdrawal occurs due to the discontinuation or reduction of opioid use in individuals with heavy and prolonged opioid use or may be precipitated by the administration of an opioid antagonist in an individual with prolonged opioid use or by the administration of an opioid partial agonist in an individual that is currently using a full opioid agonist. Symptoms of withdrawal from opiates include, but are not limited to, depression, anxiety, irritability, leg cramps, abdominal cramps, nausea, vomiting, diarrhea, insomnia, pain, tremor, rhinorrhea, sweating, and cravings for the drug itself. Depending on the opioid's half-life, the symptoms of opioid withdrawal usually resolve within 5 to 14 days, however, many patients require appropriate treatment. The DSM-V diagnostic criteria is used for the diagnosis of opioid withdrawal. The medications for treatment include methadone, clonidine, buprenorphine, and adjunctive drugs.

Historical Perspective

  • Opium and its derivatives have been used as medical therapies since 5,000 years ago.[1]
  • In the United States, in the early 20th century, opiates were over-the-counter drugs and were commonly used in medical therapy of various disorders.[1]
  • In the early 1900s, the federal restrictions on opioid access caused suffering and death since there were no effective treatments for the opioid withdrawal symptoms that happened with sudden discontinuation of opioids.[1]

Classification

The onset and duration of opioid withdrawal depends on the half-life of the consumed opioid:[2][1][3][4][5]

Half-life of Opioids Onset of Withdrawal Symptoms Duration of the syndrome
Short half-life
  • Within 12 h of last use
  • Heroin withdrawal lasts 4–5 days
Long half-life
  • 1–3 days after last use
  • Methadone withdrawal lasts 7–14 days
  • Some last for several weeks

Pathophysiology

Chronic opioid use leads to changes in different organs and these may be the underlying pathophysiology of opioid withdrawal symptoms, such as:[6][1]

Locus coeruleus (LC)

Locus ceruleus(LC):[6]

Acute opioid effects:

Chronic opioid use:

Opioid tolerance occurs with the adaption of LC neurons to opioid inhibition by increasing enzyme activity which leads to:

  • Upregulation of the cAMP pathway and production of normal cAMP levels:
    • Return to normal levels of LC firing rate and NE release

Abrupt discontinuation of opioids after opioid tolerance:

Sudden discontinuation of opioids in chronic opioid users that have opioid tolerance causes the following until re-adaptation to the absence of opioids occurs in LC neurons:[7][8] 

  • Hyperactivation of LC
  • Increased production of cAMP
  • Excessive release of NE

Noradrenergic hyperactivity is the main cause of acute opioid withdrawal symptoms.

Causes

Opioid withdrawal symptoms may occur with:[9]

Differentiating opioid withdrawal from other diseases and conditions

Opioid withdrawal must be differentiated from:[10]

Disease Prominent clinical features Investigations
Hyperthyroidism The main symptoms include:
  • The patient usually has elevated T3 and T4
  • TSH might be increased or decreased depending on the underlying cause
  • Thyroid-stimulating antibodies (TSI) might be increased in cases of Graves’ disease
Essential hypertension Most patients with hypertension are asymptomatic at the time of diagnosis. Common symptoms are listed below: JNC 7 recommends the following routine laboratory tests before initiation of therapy for hypertension:
Generalized anxiety disorder According to DSM V, the following criteria should be present to fit the diagnosis of generalized anxiety disorder:
  1. The presence of a sense of apprehension or fear toward certain activities for most of the days for at least 6 months
  2. Difficulty to control the apprehension
  3. Associated restlessness, fatigue, irritability, difficult concentration, muscle tension or, sleep disturbance (only one of these manifestations)
  4. The anxiety or the physical manifestations must affect the social and the daily life of the patient
  5. Exclusion of another medical condition or the effect of another administered substance
  6. Exclusion of another mental disorder causing the symptoms
-
Menopause The perimenopausal symptoms are caused by an overall drop, as well as dramatic but erratic fluctuations, in the levels of estrogens, progestin, and testosterone. Some of these symptoms such as formication, etc. may be associated with the hormone withdrawal process.
  • B-HCG should always be done first to rule out pregnancy especially in women under the age of 45 years
  • FSH can be measured but it can be falsely normal or low
  • TSH, T3, and T4 to rule out thyroid abnormalities
  • Prolactin can be measured to rule out prolactinoma as a cause of menopause
Opioid withdrawal disorder According to DSM V, the following criteria should be present to fit the diagnosis of opioid withdrawal:
  1. Cessation of (or reduction in) opioid use that has been heavy and prolonged (i.e., several weeks or longer) or administration of an opioid antagonist after a period of opioid use.
  2. Development of three or more of the following criteria minutes to days after cessation of drug use: dysphoric mood, nausea or vomiting, muscle aches, Lacrimation or rhinorrhea, pupillary dilation, piloerection, or sweating, diarrhea, yawning, fever, and insomnia.
  3. The signs or symptoms mentioned above must cause impairment of the daily functioning of the patient.
  4. The signs or symptoms mentioned above must not be attributed to other medical or mental disorders.
  • Urine drug screen to rule out any other associated drug abuse
  • Routine blood work such as electrolytes and hemoglobin to rule out any associated disease explaining the symptoms
Pheochromocytoma The hallmark symptoms of pheochromocytoma are those of sympathetic nervous system hyperactivity, symptoms usually subside in less than one hour and they may include:

Please note that not all patients with pheochromocytoma experience all of the classical symptoms.

Diagnostic lab findings associated with pheochromocytoma include:

Epidemiology and Demographics

  • The prevalence of opioid withdrawal is 6,000 per 100,000 (60%) of the population that have used heroin one or more time in the prior 12 months.[10]
  • In the USA, the amount of opioids prescribed has increased from 43.8 million prescriptions in 2000 to 89.2 million in 2010.[11]
  • About 4% of adults in the USA regularly use opioids for pain.[12]

Risk Factors

Opioid withdrawal may be caused by discontinuation of repeated use of an opioid in any setting such as:[10]
