Heroin Withdrawal Symptoms

Heroin addiction can result in tolerance to and dependence on the drug. When tolerance happens, individuals need more of the drug to achieve the same effect. Dependence on heroin means the person is returning to using heroin to stop withdrawal symptoms. The primary risk associated with the withdrawal symptoms from heroin is subsequent overdose due to loss of tolerance.

What causes heroin withdrawal to occur? All opioids, especially heroin, can become habit-forming. When you build a tolerance to heroin, you need to use more of it to obtain the same high. Eventually, you can become physically and psychologically dependent on the drug. Chronic heroin use alters the nerve receptors in your brain. They come to depend on opioids, particularly heroin, to function. If you stop using heroin or reduce your intake, you may experience withdrawal symptoms. The withdrawal symptoms represent your body’s physical response to the absence of heroin.

What are the Symptoms of Heroin Withdrawal?

Heroin withdrawal manifestation may develop rapidly. For instance, a person with a strong physical dependence might begin to experience them in hours. Over the following days, the withdrawal symptoms become more intense before peaking and then gradually subsiding. The National Institute on Drug Abuse (NIDA) reports that while heroin withdrawal symptoms tend to improve after a week, they may sometimes stay for months.

Here are some common signs of heroin withdrawal:

Seeking professional medical and mental health support during heroin withdrawal can help individuals manage these symptoms safely and effectively. In this article, we will tackle in-depth symptoms of withdrawal from heroin, how to get help, and where to get treatment where you can detox safely from heroin and drug use.

Heroin Withdrawal Fact Sheet

Heroin Drug Class: Heroin is an opioid drug made from morphine.
Heroin Drug Schedule: Schedule I. It has a high potential for addiction and no currently accepted medical use in therapy and treatment in the US.

Heroin Withdrawal Treatment

When persons addicted to opioids like heroin first stop, they experience severe withdrawal symptoms (pain, diarrhea, nausea, and vomiting). Medications might be beneficial during the detoxification period. This alleviates cravings and other bodily signs that can frequently lead to relapse.

Medication-assisted treatment (MAT) can be considered by all individuals seeking treatment for heroin addiction. Drugs such as Suboxone and Vivitrol may aid heroin addicts in their recovery.

• Lofexidine.
  • Lofexidine is a medication approved by the US Food and Drug Administration (FDA) for treating opioid withdrawal symptoms, including those associated with heroin withdrawal. It is marketed under the brand name Lucemyra.
• Methadone.
  • It is a long-acting opioid agonist. Methadone is administered orally to reach the brain slowly and avoid withdrawal symptoms. Methadone is only accessible in authorized treatment programs, where it is given to patients regularly.
• Buprenorphine (Subutex).
  • FDA approved. Buprenorphine reduces drug cravings without the “high” or hazardous side effects associated with other opioids. Suboxone is a new buprenorphine formulation that is taken orally and contains Naloxone (an opioid antagonist) to prevent efforts to get high by injecting the medicine.
• Naltrexone (Vivitrol).
  • FDA approved. It is a medication primarily used to manage alcohol or heroin addiction by reducing cravings and feelings of euphoria associated with substance abuse. Heroin addicted person should not receive naltrexone before detoxification.

Anyone who exhibits symptoms of an opioid overdose or suspects an overdose should be given Naloxone. It can be administered through injection into the muscle, skin, or veins or as a nasal spray.

Post-Acute Withdrawl Syndrome (PAWS)

Unfortunately, some people develop post-acute withdrawal syndrome, often known as PAWS, while going through the heroin withdrawal process. This happens when a person has withdrawal symptoms over a lengthy period. Recovering heroin users may have symptoms for several weeks or even months.

PAWS can be a regular part of the recovery process and does not necessarily indicate unsuccessful treatment. With appropriate treatment and support, individuals can manage PAWS symptoms and maintain long-term recovery from heroin addiction.

Heroin Withdrawal Seizure

Seizures can occur during the acute withdrawal period, typically within the first 1-3 days after the last use of heroin.

The risk of seizures during heroin withdrawal increases in individuals with a seizure history, head injuries, or other medical conditions affecting the brain. The health risk is also higher in individuals who have used large amounts of heroin for an extended period, which can lead to more severe withdrawal symptoms.

Heroin Withdrawal Symptoms Hypertension

High blood pressure is a common symptom of heroin withdrawal. This is because heroin use can cause changes in the cardiovascular system, leading to increased blood pressure and heart rate.

During heroin withdrawal, the body adjusts to the absence of the drug, and the sympathetic nervous system is activated, which can cause a surge in blood pressure. This increase in blood pressure can be hazardous for people with heart disease.

If you are experiencing hypertension during heroin withdrawal, it is critical to seek medical attention. A healthcare professional can monitor your blood pressure and provide medications to help manage the symptoms. It is also crucial to make lifestyle changes, such as lessening salt intake, exercising physical activity, and avoiding alcohol and tobacco, to help manage blood pressure and improve cardiovascular health.

Top 3 Heroin Withdrawal Symptoms FAQs

How Long Does It Take To Withdraw From Heroin?

The withdrawal symptoms heroin can produce usually last about a week. However, the experience is different for everyone. Several factors play a role in how the body reacts to heroin withdrawal. These may include the amount of heroin taken in each dose, how long heroin was abused, and how the person ingested the drug (snorting, smoking, shooting, or booking). Withdrawal symptoms of heroin may also be influenced by underlying mental health problems or a prior history of opioid abuse.

One of the many reasons heroin can be damaging is that it suppresses the normal functions of the central nervous system (CNS). As a result, it can harm your breathing, body temperature, and blood pressure. Since opioids like heroin bind to opioid receptors in the brain, the person using the drug can end up with changes in brain chemistry that affect how they experience pleasure and pain. When someone goes through heroin withdrawal, they may experience sensations opposite the highs they previously enjoyed. For instance, the heart rate can slow, and they may feel anxious or depressed.

What Does Heroin Withdrawal Feel Like?

Heroin withdrawal can cause various physical and psychological symptoms, varying in severity and duration based on the individual and the extent of their heroin use. Some common physical symptoms of heroin withdrawal include the following:

Symptoms of Heroin Withdrawal Cravings

Most people experiencing heroin withdrawal are highly urged to take more heroin drugs. This is also called “experiencing cravings” and is very common among people withdrawing from addictive substances. Part of the craving is motivated by the desire to reduce the symptoms of heroin withdrawal, and part of it is the yearning to re-experience the pleasure of the heroin high.

Mood Changes During Heroin Withdrawal

Feeling irritable, anxious, or depressed, also known as having a “dysphoric mood,” is a common symptom of heroin withdrawals. Even without a traumatic past, one is expected to experience these mood changes. Still, many people who use heroin experience long-suppressed feelings connected to abuse or past trauma when they come off the drug. This is why it is critical to have emotional support while going through heroin withdrawals. These feelings become less intense once the heroin withdrawal stage is over.

Vomiting and Nausea 

Although these are distressing symptoms, nausea, and vomiting are typical for heroin withdrawals. It wears you out, makes you off your food, causes uncomfortable sensations, and keeps you close to the bathroom.

Fever from Heroin Withdrawals

Body temperature differs from person to person, as well as elements like time of day and menstrual cycle, but usually, a temperature of 99–99.5 F (37.2–37.5 C) is considered a fever in adults. A fever is one way your body combats infections and disease, but when a person goes through heroin withdrawals, the fever does not serve a practical purpose in fighting infection. Ask for medical help immediately if your temperature heightens to 103 F (40 C) and doesn’t decline treatment. If you have a severe medical condition, such as a heart problem, diabetes, sickle cell anemia, cystic fibrosis, HIV, or a seizure, get immediate help.

Stomach Pain and Diarrhea 

Diarrhea or watery and frequent bowel movements are also typical with heroin withdrawals. These withdrawal symptoms may be accompanied by stomach spasms in the digestive system. Diarrhea and stomach pain may make it challenging to go about your routine.

Restlessness and Sleep Problems

Individuals going through heroin withdrawals usually experience restlessness, which, coupled with insomnia and anxiety, can simultaneously make you feel agitated and tired. Heroin withdrawals often cause sleep problems, particularly insomnia. Yawning is also common.

Coping & Relief

While heroin withdrawal can be uncomfortable and intense, the worst symptoms occur within a week. At this moment, there are some things that you can do to aid yourself to feel more comfortable.

Pains and Aches

One of the primary roles of heroin works is to block the body’s pain pathways. When you go through heroin withdrawals, there is a rebound effect, and you feel pain, primarily in the legs and back, and feel more sensitive to pain.

Excessive Bodily Fluids

As you undergo heroin withdrawal, you may encounter an overproduction of tears, sweat, and a runny nose. You may also notice your hair standing on end. Comparable with other physical withdrawal symptoms, these body responses bring themselves into balance.

How Long Does Heroin Withdrawal Last?

The terrible withdrawal symptoms may peak after a week of no drugs and typically last up to 14 days. So you initially start feeling symptoms within a day, which is why someone with an addiction to heroin wants to have this drug in their system at all times. But the symptoms can get progressively worse for up to a week, lasting up to two weeks until it’s out of their system.

How Long is Heroin Withdrawal by Days?

How long does it take to withdrawal from heroin? The initial comedown of withdrawal from heroin can vary in time and intensity. Typically, heroin withdrawal symptoms begin six to twelve hours after the last dosage, peak within one to three days, and progressively subside over the next five to seven days. However, some users experience withdrawal symptoms for weeks or months, a condition known as post-acute withdrawal syndrome (PAWS).

Another common question is about how long heroin withdrawals will happen. Heroin leaves the body within a matter of days. The digestive system metabolizes and removes it from the body over a few days. Yet, how long this takes often depends on the amount of the substance used and factors such as how healthy your body is and if it can metabolize substances quickly.

Heroin withdrawal will continue until your body and brain move beyond dependence. This is a difficult period for some people. That is why most heroin addiction treatment centers offer a comprehensive treatment program incorporating medications that ease the brain off heroin. It takes less pain and frustration to get beyond that withdrawal, then. For most people, you can start feeling better in a few days.

Can You Die From Heroin Withdrawals?

Withdrawing from any opioid can be lethal. The safest way to get rid of this drug from your body (detox) is under medical care. As uncomfortable as heroin withdrawal symptoms are, they aren’t usually life-threatening. However, they are painful and uncomfortable enough to make at-home detox dangerous. During an at-home detox, a person starts to crave heroin while also experiencing withdrawal symptoms. To ease their pain, they use heroin. However, now that they are clean, their body is no longer accustomed to the drug. They may return to using the same amount as they previously did, but it can be overwhelming for their body, causing an overdose and death.

Excessive vomiting and diarrhea are other causes of death from heroin withdrawal. If left untreated, these symptoms can dehydrate the body quickly, causing dangerously high amounts of salt to collect in the blood (hypernatremia) and cause the heart to fail. Such situations occur when people abstain from heroin on their own. Medical care at a skilled detox facility can prevent such tragedies.

Heroin Withdrawal Protocol

Heroin withdrawal protocols can vary depending on the individual’s specific needs and the detox setting (inpatient or outpatient). However, some typical steps in a heroin withdrawal protocol may include the following:

• Medical Evaluation: Before beginning the detox process, a medical evaluation is typically conducted to assess the individual’s physical and psychological health and any underlying medical conditions that may impact the detox process.
• Medication-Assisted Treatment: Medications such as buprenorphine, methadone, or naltrexone may help manage withdrawal symptoms and reduce cravings during detox. These medications are typically administered under medical supervision and may be tapered off over time.
• Heroin Withdraw Symptoms Management: Various medications may be used to manage specific withdrawal symptoms, such as clonidine for anxiety or benzodiazepines for insomnia.
• Nutritional Support: Individuals undergoing heroin detox may require nutritional support to address any deficiencies or imbalances that may have developed due to their addiction.
• Therapy and Counseling: These are essential to heroin withdrawal protocols, helping individuals address the underlying causes of their addiction and develop coping skills and strategies for long-term recovery.

Heroin Detox

Heroin withdrawal detox refers to removing heroin and other toxins from the body after chronic or long-term heroin use. The detox process can be uncomfortable and dangerous, so seeking professional medical help and supervision is recommended.

Heroin detox can be done in different settings, including inpatient or residential detox programs, based on the intensity of the substance use disorder and the individual’s specific needs. In an inpatient detox program, individuals can receive 24/7 medical supervision and support to manage withdrawal symptoms and prevent health complications, such as dehydration or seizures. Medications may also be administered during heroin detox to help manage withdrawal symptoms. These may include medicines that can help reduce cravings and ease withdrawal symptoms. Furthermore, medications may help manage anxiety, agitation, or insomnia symptoms.

In addition to medical support, individuals undergoing heroin detox may benefit from therapy and counseling to address the underlying problems that led to their addiction and develop coping skills and strategies for long-term recovery. Family support and participation in support groups can also be beneficial during the detox and recovery process.
