Key takeaway
GHB withdrawal can begin within hours of the last dose in people who use it around the clock, and it can escalate quickly to delirium, hallucinations, seizures, and dangerous heart-rate and blood-pressure swings. It should be treated in a medical setting, not at home. Call 911 for confusion or seizures, or call or text (800) 653-9376 to find medical detox.

GHB (gamma-hydroxybutyrate) is a central nervous system depressant. Its precursors GBL and 1,4-butanediol turn into GHB in the body and carry the same risks. People who use GHB occasionally may not develop dependence, but people who dose every few hours, around the clock, often do. For them, stopping suddenly can be a medical emergency.
This page is education, not a home detox plan. Call 911 for confusion, hallucinations, a seizure, or a racing heart that will not settle. Call or text 988 for a crisis.
Why GHB withdrawal is different
GHB wears off quickly, so dependent users often dose every 1 to 3 hours, including overnight. When the doses stop, withdrawal can begin within about 1 to 6 hours. Clinical reviews describe a syndrome that looks like severe alcohol or sedative withdrawal and can escalate fast. Some cases do not respond well to standard benzodiazepine treatment and need other medications and close monitoring.
Symptoms and warning signs
Early: anxiety, tremor, insomnia, sweating, nausea, and a fast heartbeat.
Severe - call 911: agitation, paranoia, hallucinations, delirium, seizures, very high heart rate or blood pressure, very high body temperature, or muscle pain with dark urine (a sign of muscle breakdown).
Severe GHB withdrawal can need intensive care, and symptoms can last up to about two weeks. Mixing GHB with alcohol, benzodiazepines, or opioids raises overdose risk during use and complicates withdrawal.
What medical detox looks like
A hospital or medically monitored detox team will usually:
- Ask what was used (GHB, GBL, or 1,4-butanediol), how much, and how often.
- Monitor heart rate, blood pressure, temperature, and mental status closely.
- Use sedating medications to control withdrawal and prevent seizures, adjusting quickly if symptoms escalate.
- Check for other substances, especially alcohol and benzodiazepines.
- Plan next steps after detox, such as residential or outpatient treatment and relapse prevention.
Call or text (800) 653-9376 to find a detox program that can handle GHB withdrawal, or use this form:
Calling is free; the referral service is paid for by treatment providers, and we check your benefits before you commit.
You can also search findtreatment.gov and filter for detoxification. When you call, say clearly that GHB or GBL is involved so the program can confirm it has the right level of medical care.
After detox
Detox handles the physical withdrawal. Staying stopped usually takes ongoing treatment, sleep and anxiety care, and support around the settings where GHB was used. See what medically supervised detox is for how detox connects to the rest of care.

Common Questions
How soon does GHB withdrawal start?
For people who dose every few hours, day and night, withdrawal can begin within about 1 to 6 hours of the last dose. That fast onset is one reason GHB dependence is hard to manage at home.
Is GHB withdrawal dangerous?
Yes. Severe GHB withdrawal can cause agitation, hallucinations, delirium, seizures, high heart rate and blood pressure, and muscle breakdown. Severe cases can require intensive care, and symptoms may last up to about two weeks.
Are GBL and 1,4-butanediol the same as GHB for withdrawal?
They are converted into GHB in the body, so dependence and withdrawal follow the same pattern. Withdrawal from GBL or 1,4-butanediol needs the same medical caution.
Can I taper GHB at home?
Do not try. Street GHB doses are unpredictable, and withdrawal can turn severe within hours. Medical detox can use medications and monitoring that are not available at home.
Where can I get help for GHB dependence?
Ask for a hospital-based or medically monitored detox program and say clearly that GHB, GBL, or 1,4-butanediol is involved. Call or text (800) 653-9376 or search findtreatment.gov for detoxification services. In an emergency, call 911.
