Heroin withdrawal occurs when you stop using this fiercely addictive substance after sustained use.

Heroin is a semi-synthetic opioid that interacts with your brain’s natural opioid receptors, delivering pain-relieving and rewarding properties.

In your brain, you have neurotransmitters associated with mood and movement, as well as essential physiological processes. These neurotransmitters or chemical messengers are designed to deliver endorphins when required. Using a drug like heroin continuously floods your brain with endorphins and dopamine, which induces a sense of euphoria.

Tolerance to heroin rapidly builds as the drug triggers significant changes in brain chemistry. It is inadvisable and potentially dangerous to abruptly stop using heroin without consulting your healthcare provider, as it will likely require medical supervision during the withdrawal phase.

Fortunately, clinically supervised withdrawal at a licensed addiction treatment center can minimize the discomfort of withdrawal. According to SAMHSA (Substance Abuse and Mental Health Services Administration), medication-assisted treatment is effective for heroin withdrawal.

Heroin Withdrawal

If you become physically dependent on heroin, just like any opioid, discontinuing use will cause intensely uncomfortable withdrawal symptoms, which can lead to heroin abuse and addiction.

You will experience withdrawal symptoms for the duration of the first few weeks after cessation of the drug. During this initial withdrawal phase, heroin and its toxic metabolites leave your system, and your body struggles to cope with this change.

For many people who have used heroin long-term, the fear of withdrawal symptoms becomes a barrier to obtaining treatment.

While heroin withdrawal is uncomfortable, the symptoms are manageable with the right support. A practical first step in this process is learning about what to expect as heroin withdrawal unfolds.

Heroin withdrawal symptoms will differ from person to person, but many experiences are similar. Various factors influence the extent and severity of these symptoms, including:

• Duration of heroin drug abuse
• How much of the drug is used
• Route of administration
• Any underlying medical conditions
• Presence of co-occurring disorder
• Previous opioid withdrawal history

Withdrawal symptoms during heroin withdrawal are the opposite of the drug’s intoxicating and pleasurable effects. Heroin use suppresses certain functions of the central nervous system and enhances feelings of pleasure, but when heroin is no longer in the body, it leads to:

• Increased heart rate
• Lowered mood
• General anxiety

Complications During Heroin Withdrawal

The heroin withdrawal process occurs similarly to withdrawal from prescription opioids, although the presentation of symptoms is typically more intense. Learning how to withdraw from heroin comfortably and safely will minimize discomfort during the initial phases and will reduce the chance of relapse in recovery.

In almost all cases, supervised clinical treatment is the most efficient route to safely withdraw from an opioid like heroin and begin your ongoing recovery with inpatient or outpatient treatment.

If you are trying to quit heroin at home without medical guidance, it can be dangerous and even life-threatening. Most individuals who abruptly stop using heroin without medical supervision find the withdrawal symptoms so aggravating that they relapse before successfully overcoming their dependency.

The symptoms experienced during heroin withdrawal are similar to the symptoms of a bad case of influenza. Most symptoms peak during the second and third days of heroin withdrawal and then subside after about a week.
