Opioid Withdrawal Timeline

Opioid Withdrawal Timeline & Treatment Options

How long does opioid withdrawal last?

Opioids are a class of drugs that include illegal substances like heroin as well as prescription painkillers, such as oxycodone, that doctors may prescribe to treat chronic pain. Even when used as prescribed, prolonged opioid use can lead to dependence, which means individuals can develop uncomfortable opioid withdrawal symptoms when they stop using them. 

Opioids blocks pain messages between the brain and the rest of the body. This can give pain relief but may also slow the heart rate and breathing. Opioid withdrawal symptoms are adverse effects that can happen if a person suddenly stops using or suddenly reduce the dosage of, an opioid medicine. Opioids are sometimes abused, as they can assist with mental relaxation and pain relief and can produce a sense of euphoria. 

Opioid Withdrawal Timeline
Just because a doctor prescribes an opioid doesn’t mean that it’s safe for everyone. 

When someone stops taking an opioid drug suddenly, the first symptoms of withdrawal can appear within hours. Withdrawal from short-acting opioids like heroin can start within six to 12 hours of the last use and can continue for four to 10 days.  How long opioid withdrawal lasts depends on the type of opioid you are taking. Longer-acting opioids like fentanyl and methadone take longer to leave the body, so withdrawal symptoms usually don’t emerge until 12 to 48 hours after last use. Withdrawal from these opioids also lasts anywhere from 10 to 20 days.

For short-acting opioids like heroin or oxycodone, withdrawal may last 3 to 5 days. Ways to treat mild opioid withdrawal include increased water and vitamin intake, while more severe withdrawal may require opioid use disorder medication and opioid detox treatment.  For many people, withdrawal is the most challenging barrier to recovery because all its unpleasant symptoms make sufferers believe the only way to stop the pain is to use it again. Therefore, understanding the fundamentals of opioid withdrawal is a crucial step in preparing for treatment and long-term recovery.

What Happens During Withdrawal?

Trying to eliminate or lessen opioid usage can cause some people to develop physical and psychological symptoms associated with opioid withdrawal due to the drug’s ability to alter their brain chemistry. After your body begins to adapt to the constant presence of the substance in your system, it becomes so accustomed to the presence of opioids that you’ll eventually find that you need to continue taking them to act ‘normally.’

Continued abuse of opioid drugs can lead to a tolerance to the substance, which means you’ll eventually need to take higher doses to achieve the same effects. If you attempt to stop taking the drug suddenly, your body is unable to adapt quickly.

The result can mean experiencing unpleasant physical and psychological withdrawal symptoms. Some of the symptoms can be so awful that the person may be tempted to relapse and return to retaking opioid drugs to avoid feeling such horrible symptoms.

Unfortunately, if you had built up a tolerance to opioid drugs before trying to quit, you would likely attempt to take similar doses to what you were taking before. You might not realize that you would have reduced your body’s tolerance levels during the time you tried to stop, which can lead to an accidental overdose.

The Early Phase – Six to 24 Hours After Last Use

Beginning with cravings for more opioids and symptoms of restlessness and anxiety, the early phase of the opioid withdrawal timeline increases in its adversity as the calming effects of the drugs wear off and nervous systems are re-stimulated. Other signs and symptoms of the early phase in the opioid withdrawal timeline may include:

  • Dilated pupils
  • Uncontrollable yawning
  • Runny nose
  • Teary eyes
  • Elevated heart rate and blood pressure
  • Increased respiration
  • Loss of appetite
  • Cognitive and motor functioning difficulties

The Acute Phase – 24-72 Hours After Last Use

Thoughts, emotions, pain, and stress become increasingly bothersome during the acute phase of the opioid withdrawal timeline which progresses in intensity, severity, and symptom logy, peaking at around 3-4 days. Without intervention, the withdrawal usually runs its course, and most physical symptoms disappear within days or weeks, depending on the particular drug.

Most individuals struggling with opioid addiction never complete the withdrawal process to this point or beyond because even as the physical symptoms begin to subside after several days of abstinence, the acute psychological symptoms can linger for weeks.

During the acute phase of the opioid withdrawal timeline, the person experiences intensified early phase symptoms along with possible signs and symptoms of:

  • Sweats, chills, and goose-bumps
  • Gastrointestinal distress – nausea, vomiting, diarrhea, and cramps
  • Muscle spasms, bone pains, and overall body aches
  • Extreme restlessness and insomnia
  • Fatigue, weakness, and trembling
  • Dehydration
  • Heightened sensitivities to internal and external stimuli
  • Emotional instability – rapid mood swings, aggression, anxiety, depression, and possibly suicidal ideations

The Post-Acute Withdrawal Syndrome (PAWS) Phase

Repeat intoxications and withdrawals from opioids have a harsh effect on neurobiological functions that help maintain a sense of wellbeing. Long after the drugs are out of the body, the residual effects are often intermingled with mental health disorders, social impairments, and environmental stresses that can subconsciously trigger cravings in an instant. The post-acute phase of the opioid withdrawal timeline can go on for years and last indefinitely.

What is PAWS?

Post-acute withdrawal syndrome (PAWS) is a collection of symptoms that emerge after the typical withdrawal period has ended. Withdrawal syndrome refers to the symptoms that occur when a substance-dependent person abruptly stops taking that substance.

PAWS in Opioids

Reports estimate that as many as 90% of recovering users will encounter some level of opioid post-acute withdrawal. Heroin and prescription pain medications are widely abused substances that are known to trigger post-acute withdrawal symptoms. Reports estimate that as many as 90% of recovering users will encounter some level of opioid post-acute withdrawal.

Though the symptoms will vary with each person, PAWS symptoms for opioids include:

  • Increased anxiety
  • Depression
  • Sleep problems
  • Low energy
  • Irritability
  • Weight gain
  • Increase in blood pressure
  • Quicker breathing
  • Menstrual changes

Former heroin and other opioid users frequently report problems with attention, focus, and concentration levels during post-acute opioids withdrawal. Effects such as these can lead to interpersonal relationship issues and affect school and/or job performance.

Beyond Detox: Residential Rehab and Dual Diagnosis

The body does go through specific symptom stages known as the opioid withdrawal timeline. The opioid withdrawal timeline varies from a few days to a few weeks, depending on the type of opioid that was used, how long it was used, and any other substances that may have been used in conjunction with opioids as well. Medically managed withdrawal or detoxification ensures the individual remains safe and stays as comfortable as possible.

Detox Treatment

The first step in treatment is detoxification. It will help you navigate the complicated withdrawal process, but it doesn’t address patterns of thought and behavior that contribute to Tramadol abuse. Various treatment approaches and settings can help provide the ongoing support necessary to maintain long-term sobriety after you complete detox.

Cravings are very common during detox and can be challenging to overcome. This often leads to relapse. Constant medical care provided during inpatient treatment helps prevent relapse. Clinicians can provide necessary medication and medical expertise to lessen cravings and the effects of withdrawals.


Several different modalities of psychotherapy have been used in the treatment of depression, including:

  • Cognitive Behavioral Therapy (CBT) – is an effective treatment that involves making changes in both the patterns of negative thoughts and the behavioral routines which are affecting the daily life of the depressed person for various forms of depression. 
  • Dialectical Behavioral Therapy – is a comprehensive mental health and substance abuse treatment program whose ultimate goal is to aid patients in their efforts to build a life worth living. The main goal of DBT is to help a person develop what is referred to as a “clear mind.” 
  • Person-Centered Therapy – is a strategy that allows and encourages clients to understand and resolve their concerns in a safe, supportive environment.

Dual Diagnosis Treatment

Substance abuse and mental health disorders often co-occur. In many cases, traumatic experiences can result in a mental health disorder and substance abuse. Dual diagnosis programs treat both of these issues together. The best approach for the treatment of dual diagnosis is an integrated system. In this strategy, both the substance abuse problem and the mental disorder are treated simultaneously. Regardless of which diagnosis (mental health or substance abuse problem) came first, long-term recovery will depend largely on the treatment for both disorders done by the same team or provider.

Medication-Assisted Treatments

Medication-Assisted Treatments (MAT) for substance use disorders and mental health disorders are commonly used in conjunction with one another. This includes the use of medications and other medical procedures. During your rehab, the staff from your treatment facility will help you identify what caused your addiction and teach you skills that will help you change your behavior patterns and challenge the negative thoughts that led to your addiction. Sometimes, the pressures and problems in your life lead you to rely on substances to help you forget about them momentarily.
