==Overview==
[[Opioid]] withdrawal refers to the arrays of signs and symptoms following the abrupt cessation of [[opioid]]s among chronic users.<br>


==Definition==
[[Opioids]] have analgesic and CNS depressant properties; [[tolerance]] and physiological dependence develop when these are used chronically, any abrupt cessation precipitates an array of signs & symptoms referred to as withdrawal.

==Do's==
*A signed release of information from patients who are currently enrolled in Opioid Treatment Programs (OTPs) or other programs should be obtained before initiating buprenorphine treatment.
*Initiation of buprenorphine treatment should be carefully timed such that the patients should be in the early stages of withdrawal.
*Patients should be carefully explained regarding the advantages of waiting and should be urged to wait until they begin to experience the symptoms of withdrawal. 
*Consider patients history and concerns and counsel about potential side effects from buprenorphine overdosing or underdosing before initiation.
*Buprenorphine should be administered as sublingual tablets.
**Asses the dose taken.
**Assess the amount of time the medication is allowed to dissolve under the tongue.
*After initiation, periodic reassessment regarding the patient’s motivation for treatment should be done in order to assess the duration for various aspects of treatment.
*During induction, patients should be advised to avoid driving or operating other machinery until they are familiar with the effects of buprenorphine and until their dose is stabilized.
*Pregnant women and patients on long-acting opioids should be inducted and maintained on buprenorphine monotherapy, and the number of doses should be limited.
*Non pregnant women started on buprenorphine monotherapy for induction should be switched to a buprenorphine and naloxone combination on day 2 to minimize the possibility of abuse.
*A lowest possible dose of (2/0.5 mg) of buprenorphine/naloxone for induction treatment can be considered in patients who are not physically dependent on opioids but who have a known history of opioid addiction, have failed other treatment modalities, and have a demonstrated a need to cease the use of opioids.
*Doses should be increased more rapidly, or to a higher maintenance dose level along with intensive psychosocial treatments in patients who experience withdrawal symptoms during induction or who feel compelled to use illicit drugs.  Strongly warn those who continue to take illicit opioids.   
*To determine the adequacy of clinical response, toxicology testing for drugs of abuse should be done.
*Start stabilization phase, when patient is asymptomatic, suffering minimal or no side effects and no longer craving for opioids.
*Toxicology screens must be performed atleast once a month to assess progress.
*Frequency of visits should be as follows:
:*During stabilization phase atleast once a week.
:*During maintenance phase, anywhere from biweekly to monthly visits is considered satisfactory, however must be tailored to meet patients needs.
*Use following measures to assess efficacy of treatment:
:*No evidence of ongoing drug abuse of any kind.
:*Toxicity from opioid use is absent.
:*Adverse effects due to medical treatment are absent or minimal.
:*Patient is stable with respect to psycho-social elements.
:*Treatment adherence is good.


==Dont's==
==Dont's==
* Do not abruptly stop drugs that are being used to treat withdrawal.
*Do not initiate induction until the patients have symptoms of withdrawal.
*Do not abruptly stop drugs that are being used to treat withdrawal.
*Do not prefer, short term (3 day) reduction for detoxification unless there is a strong reason for the same such as impending incarceration, foreign travel, job requirement etc.

Overview

Opioid withdrawal refers to the arrays of signs and symptoms following the abrupt cessation of opioids among chronic users.

Shown below is a table indicative of time to withdrawal symptoms for different opioids:[1][2]

Opioid Peak withdrawal symptoms Duration of symptoms
Heroin 36-72 hours 7-10 days
Methadone 72-96 hours 14 days or more
Buprenorphine 36-72 hours Intermediate between 7-14 days

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. Opioid withdrawal is a life-threatening condition and must be treated as such irrespective of the causes.

Common Causes

Management

Shown below is an algorithm used for diagnosis and treatment of withdrawal from opioids, based on hospital concepts[3] and treatment guidelines issued by Substance Abuse and Mental Health Services Administration (Center for Substance Abuse Treatment, US).[4]

Diagnostic Approach

 
 
Characterize the symptoms:
❑ Flu like illness
❑ Lacrimation
❑ Rhinorrhea
❑ Sneezing
❑ Yawning
Anorexia
Nausea
❑ Vomiting
❑ Abdominal cramps
Diarrhea
Myalgia
Arthralgia
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Examine the patient:
❑ Increased or unchanged blood pressure
❑ Increased or unchanged heart rate
❑ Increased or unchanged respiratory rate
Mydriasis
❑ Piloerection
Tremor
❑ Increased bowel sounds
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Consider alternative diagnosis:
❑ Alcohol withdrawal
Sedative hypnotic withdrawal
Cholinergic poisoning
Sympathomimetic intoxication
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Diagnostic criteria:
❑ A. Either of the following
❑ Cessation of or reduction in opioid use that has been heavy and for several weeks or longer
❑ Administration of an opioid antagonist after a period of opioid use

❑ B. Three or more of the following (developing within minutes to several days after criterion A)

Diarrhea
Dysphoric mood
Fever
Insomnia
Lacrimation or rhinorrhea
❑ Muscle aches
Nausea or vomiting
Pupillary dilation, piloerection, or sweating
Yawning
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Opioid withdrawal
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Consider treatment with:
❑ Opioid maintenance treatment
or
❑ Medically supervised withdrawal (detoxification)

❑ Discontinue short acting opioids
❑ Look for withdrawal symptoms (12-24 hours after last dose)
 
 
 
 
 
❑ Taper long acting opioids (over a period of 1 week):
Methadone to ≤ 30 mg/day
❑ LAAM to ≤ 40 mg/48 hours

❑ Look for withdrawal symptoms:

❑ For methadone: 24+ hours after last dose

OAT: Opioid agonist therapy; LAAM: Levo-α-acetylmethadol

Do's

  • A signed release of information from patients who are currently enrolled in Opioid Treatment Programs (OTPs) or other programs should be obtained before initiating buprenorphine treatment.
  • Initiation of buprenorphine treatment should be carefully timed such that the patients should be in the early stages of withdrawal.
  • Patients should be carefully explained regarding the advantages of waiting and should be urged to wait until they begin to experience the symptoms of withdrawal.
  • Consider patients history and concerns and counsel about potential side effects from buprenorphine overdosing or underdosing before initiation.
  • Buprenorphine should be administered as sublingual tablets.
    • Asses the dose taken.
    • Assess the amount of time the medication is allowed to dissolve under the tongue.
  • After initiation, periodic reassessment regarding the patient’s motivation for treatment should be done in order to assess the duration for various aspects of treatment.
  • During induction, patients should be advised to avoid driving or operating other machinery until they are familiar with the effects of buprenorphine and until their dose is stabilized.
  • Pregnant women and patients on long-acting opioids should be inducted and maintained on buprenorphine monotherapy, and the number of doses should be limited.
  • Non pregnant women started on buprenorphine monotherapy for induction should be switched to a buprenorphine and naloxone combination on day 2 to minimize the possibility of abuse.
  • A lowest possible dose of (2/0.5 mg) of buprenorphine/naloxone for induction treatment can be considered in patients who are not physically dependent on opioids but who have a known history of opioid addiction, have failed other treatment modalities, and have a demonstrated a need to cease the use of opioids.
  • Doses should be increased more rapidly, or to a higher maintenance dose level along with intensive psychosocial treatments in patients who experience withdrawal symptoms during induction or who feel compelled to use illicit drugs. Strongly warn those who continue to take illicit opioids.
  • To determine the adequacy of clinical response, toxicology testing for drugs of abuse should be done.
  • Start stabilization phase, when patient is asymptomatic, suffering minimal or no side effects and no longer craving for opioids.
  • Toxicology screens must be performed atleast once a month to assess progress.
  • Frequency of visits should be as follows:
  • During stabilization phase atleast once a week.
  • During maintenance phase, anywhere from biweekly to monthly visits is considered satisfactory, however must be tailored to meet patients needs.
  • Use following measures to assess efficacy of treatment:
  • No evidence of ongoing drug abuse of any kind.
  • Toxicity from opioid use is absent.
  • Adverse effects due to medical treatment are absent or minimal.
  • Patient is stable with respect to psycho-social elements.
  • Treatment adherence is good.

Dont's

  • Do not initiate induction until the patients have symptoms of withdrawal.
  • Do not abruptly stop drugs that are being used to treat withdrawal.
  • Do not prefer, short term (3 day) reduction for detoxification unless there is a strong reason for the same such as impending incarceration, foreign travel, job requirement etc.
