Heroin is a powerful opioid that rapidly creates physical dependence and psychological cravings. When someone stops using, the body reacts with intense withdrawal symptoms—often pushing people to relapse before recovery can begin. But with the right understanding, medical support, and treatment plan, this first hurdle can be managed safely.

This guide outlines the full heroin withdrawal timeline, symptoms to expect, medications that help, and steps to begin a successful recovery.

Why Does Heroin Withdrawal Happen?

Heroin binds to the brain’s opioid receptors, triggering dopamine release and numbing both physical and emotional pain. With continued use, the brain reduces its natural chemical production and becomes dependent on the drug.

When heroin use suddenly stops, the brain is thrown off balance. This leads to physical and psychological symptoms as the body attempts to regain equilibrium.

According to the National Institute on Drug Abuse (NIDA), over 1 million people in the U.S. had heroin use disorder in 2021—making withdrawal a common but critical phase in the recovery process.

Heroin Withdrawal Symptoms

Withdrawal symptoms vary in severity based on usage patterns, dosage, and overall health. Symptoms typically fall into three phases:

Early Withdrawal (6–12 hours after last dose)

• Anxiety and restlessness
• Muscle aches and joint pain
• Excessive yawning
• Sweating and chills
• Runny nose and watery eyes
• Insomnia

Peak Withdrawal (1–3 days after last dose)

• Nausea and vomiting
• Diarrhoea and stomach cramps
• Dilated pupils and blurry vision
• Goosebumps
• Rapid heart rate and elevated blood pressure
• Intense drug cravings

Lingering Withdrawal (Up to 2 weeks or longer)

• Mood swings and depression
• Low energy and fatigue
• Disturbed sleep patterns
• Ongoing cravings

In some individuals, Post-Acute Withdrawal Syndrome (PAWS) can extend symptoms like depression and cravings for months after initial detox.

The Heroin Withdrawal Timeline: What to Expect

Medications That Help During Withdrawal

Medication-assisted treatment (MAT) can dramatically ease symptoms, prevent relapse, and improve long-term outcomes. The most commonly used medications include:

Methadone

• A full opioid agonist that reduces withdrawal without producing a strong high
• Dispensed daily at specialised clinics
• Especially helpful for long-term maintenance

Buprenorphine (Suboxone/Subutex)

• A partial agonist—less risk of abuse, but effective at reducing cravings
• Available through certified outpatient providers
• Often used for both detox and maintenance

Clonidine or Lofexidine

• Non-opioid medications that reduce sweating, anxiety, and agitation
• Often used short-term during acute detox

Naltrexone (Vivitrol)

• Opioid antagonist—blocks the effects of heroin entirely
• Must be used after full detox
• Helps prevent relapse in later recovery

According to SAMHSA, MAT significantly improves treatment retention and reduces the risk of overdose.

Safe Detox: Inpatient vs. Outpatient Care

Medically supervised detox is strongly recommended—especially for those with long-term heroin use or co-occurring mental health issues.

Inpatient Detox

• 24/7 medical monitoring and emotional support
• Ideal for those with severe addiction or unsafe home environments
• Helps stabilise both body and mind before rehab

Outpatient Detox

• Allows individuals to live at home
• Best for mild to moderate withdrawal with strong social support
• Requires a structured treatment plan and commitment

Aftercare: Recovery Beyond Withdrawal

Detox is only the beginning. Without a long-term recovery plan, relapse risk remains high.

Ongoing Therapy

• CBT (Cognitive Behavioural Therapy): Helps identify and reframe negative thinking
• MI (Motivational Interviewing): Strengthens internal motivation
• Family Therapy: Rebuilds trust and communication

Support Groups

• Narcotics Anonymous (NA): Peer-led 12-step program
• SMART Recovery: Secular, evidence-based program focused on self-management

Lifestyle Changes

• Exercise to improve mood and reduce cravings
• Healthy nutrition to restore energy and brain function
• Mindfulness practices like meditation and journaling

When to Seek Help

You should seek professional support if:

• Withdrawal feels too overwhelming to manage
• There is a history of relapse, overdose, or co-occurring disorders
• You experience depression or suicidal thoughts
• Your environment is unstable or unsupportive

Final Thoughts

Heroin withdrawal is painful—but it’s temporary. With proper care, support, and medication, the body and mind can heal. The hardest part—starting—is also the most important step.

Recovery doesn’t end with detox. It’s a daily process of building resilience, learning new habits, and staying connected to support.

Withdrawal is the storm. Recovery is the horizon. And it’s absolutely within reach.
