Heroin Withdrawal Timeline
What Is Heroin?
Heroin use in the United States has been rising since 2007.1 Heroin is an illegal, highly addictive opioid drug that’s processed from the seed pod of certain varieties of poppies.2 It’s often a white or brownish powder, but may also be a thick, sticky substance that’s known as “black tar.”3 Heroin can be injected, inhaled, or smoked.3 When administered, the user feels a surge—or “rush”—of pleasure as the drug quickly enters the brain and binds to the mu-opioid receptors.4 These receptors help to regulate pain, hormone release and feelings of wellbeing.4
According to the 2018 National Survey on Drug Use and Health, approximately 5.1 million Americans aged 12 or older reported using heroin at least once in their lives in in 2018, and about 526,000 people aged 12 or older in 2018 had a heroin use disorder.5 The average age of first use of heroin in 2013 was 24.5 years.6
Effects of Heroin Use
The rush users experience is also accompanied by dry mouth, skin flushing and a feeling of heaviness in the extremities.7 Some people also experience nausea, vomiting, and severe itching.7 The person’s mental function is clouded, their heartrate and breathing slows and they feel quite drowsy for several hours.7 The withdrawal timeline varies depending on a person’s history of heroin use, the doses regularly taken, and the person’s body composition, among other factors.
Repeated exposure to heroin changes the structure and chemistry of the brain. It can affect abilities in the areas of decision-making, behavior regulation, and responses to stressful situation.8
Withdrawal Symptoms and Timeline
Once a person who is dependent on heroin stops taking the drug—or any other opioid—the heroin user’s body attempts to readjust.9
Heroin withdrawal symptoms appear as early as 4 hours after the last dose of heroin.9 The distressing and uncomfortable withdrawal symptoms are accompanied by anxiety and a craving for the drug, as well as:
- Tearing up.
- Runny nose.
- Stomach cramps.
These initial symptoms are followed by gooseflesh/goose pimples, tremors, muscle twitching, low blood pressure, nausea, vomiting, stomach cramps, and diarrhea. These symptoms peak within 48 to 72 hours and persist for about a week.9
Although heroin withdrawal can be very unpleasant, it is not typically life-threatening.
Psychological symptoms may linger, and even after withdrawal is over, a heroin user may still feel significant anxiety, trouble sleeping, and drug cravings, which can last for weeks or months.19
Treatment for Heroin Withdrawal
The first part of heroin addiction treatment includes opioid detoxification, or medically managed withdrawal, which typically includes the following objectives:
- Alleviate distress and unpleasant physical and psychological symptoms.
- Prevent life-threatening complications of withdrawal.
- Provide long-term treatment after withdrawal has subsided.
- Break the pattern of drug use.
Complications can sometimes occur during withdrawal management increasing the associated health risks. Withdrawal may cause vomiting, which puts a person at risk for aspiration, or breathing stomach contents into the lungs. Aspiration can lead to lung infections. In addition, vomiting and diarrhea can also lead to dehydration, which can involve chemical and mineral imbalances.
Heroin addiction treatment may also involve medication. A variety of different medications may be used to lessen the symptoms of withdrawal.10 The most commonly used medication is clonidine, which reduces anxiety, muscle aches and cramping, and sweating. Other medications may be employed to treat vomiting and diarrhea.10
In addition to medication, peer-support groups, such as 12-Step programs and others, can assist individuals experiencing withdrawal from heroin and other opiates. Long-term treatment for drug addiction is also recommended after withdrawal has subsided. This may involve self-help programs, inpatient or outpatient treatment, and participation in individual and group therapy.
