Detoxing from heroin usually takes 5 to 10 days, depending on the individual’s usage history, overall health, and whether medical support is involved. Withdrawal symptoms often begin within 6 to 12 hours after the last dose and peak around 2 to 3 days.

What Happens During Heroin Detox?
Heroin detox is the process of eliminating the drug from your system. The body adjusts to functioning without the opioid, which can trigger intense physical and psychological withdrawal symptoms.

Common symptoms include:
- Nausea and vomiting
- Muscle aches
- Anxiety and depression
- Sweating and chills
- Insomnia and restlessness
Detox Timeline: What to Expect
Day 1–2: Withdrawal Begins
- Symptoms begin 6–12 hours after the last use
- Early symptoms: agitation, muscle aches, anxiety, insomnia
Day 3–4: Peak Withdrawal
- Symptoms intensify, including nausea, abdominal cramps, and sweating
- Cravings may be strongest during this phase
Day 5–7: Symptoms Subside
- Physical symptoms begin to ease
- Psychological symptoms may continue, such as mood swings and anxiety
Day 8–10+: Stabilization
- Most acute symptoms resolve
- Individuals may continue experiencing fatigue, depression, or cravings
Factors That Influence Detox Duration
Several variables affect how long it takes to detox from heroin:
- Duration of Use: Longer use leads to more prolonged withdrawal
- Amount and Frequency: High doses and frequent use result in more intense symptoms
- Method of Use: Injecting or smoking heroin may accelerate dependence
- Overall Health: Stronger immune systems and liver function can aid in faster detox
Why Medical Detox Is Recommended

Withdrawing from heroin can be physically and emotionally challenging. Medical detox provides:
- 24/7 Monitoring: Healthcare providers manage symptoms and ensure safety
- Medications: Use of medications like buprenorphine or methadone to ease symptoms
- Emotional Support: Counseling and encouragement throughout the process
To begin recovery in a safe environment, consider a certified heroin detox program.
Risks of At-Home Detox
Attempting detox without medical supervision can be risky due to:
- Dehydration from vomiting and diarrhea
- Increased risk of relapse due to cravings
- Worsening of underlying mental health conditions
What Comes After Detox?
Detox is only the first step. Long-term recovery requires ongoing treatment through:
- Inpatient rehab
- Intensive outpatient programs
- Behavioral therapy and counseling
- Support groups and peer mentorship

Heroin detox typically lasts 5 to 10 days, but the path to recovery extends beyond the physical withdrawal phase. Medical detox offers a safer, more comfortable experience, and continued treatment helps ensure long-term success. If you or someone you know is considering detox, seeking professional support is the most effective first step toward sobriety.
