Stopping GHB can cause anxiety, tremors, and trouble sleeping. You might also sweat or feel sick to your stomach. These symptoms can get serious. So, you need a doctor to check on you. Do not try to manage withdrawal at home.
GHB is a sedative. You can learn more about sedative withdrawal safety for general context.

Recognize an Emergency
If someone is unresponsive, has breathing problems, or may have overdosed, call 911 or go to the nearest emergency room now. Do not wait to see if the person wakes up on their own.
It is important to recognize that some symptoms can signal either intoxication or severe withdrawal, and both require immediate help. Signs of GHB intoxication include not waking up and slow or odd breathing. Signs of severe withdrawal include a seizure, severe confusion, hallucinations, a high fever, or a racing heart. If you see any of these signs, call 911 or go to the nearest emergency room now.
Do not try to watch over someone at home if they seem to have overdosed or are showing signs of severe withdrawal. A GHB-related coma is a medical emergency and is not just deep sleep.
After you have called for help, you can learn more about when withdrawal needs emergency care. Never delay calling 911 or going to the nearest emergency room to read more information.
Symptoms and How They Can Change Over Time
Common symptoms of stopping GHB include anxiety, tremor, insomnia, sweating, and nausea or vomiting. This list is not complete. Other symptoms can happen too.
Less severe signs may include restlessness or muscle aches. Severe signs include agitation, confusion, hallucinations, delirium, and seizures.
If someone has a seizure, severe confusion, hallucinations, a high fever, or a racing heart during withdrawal, call 911 or go to the nearest emergency room now.
Timing figures come from clinical reports. Do not use them to guess your own course. Do not use them to decide if it is safe to wait.
Variable onset
Symptoms may begin within hours after stopping use in reported cases
Variable duration
Acute symptoms may last days in some reported cases
After stopping use
Symptoms may begin within hours in reported cases.
During the acute phase
Symptoms may stay mild or become severe. Experiences vary widely.
As days pass
Acute symptoms may last days in reported cases. The exact length depends on the person.
Next step
Medical checks and monitoring determine the next steps.
Severity scales reflect current signs and symptoms. They should not be used alone to determine level of care.[1] GHB withdrawal can change quickly and unpredictably. Medical evaluation is essential rather than relying on a fixed timeline.
Withdrawal, Intoxication, and Coma Are Different
It is hard to tell if someone is experiencing withdrawal, intoxication, or a coma just by looking at them. The signs can look similar. Only a medical professional can determine what is happening. Understanding the differences can help you know when to act quickly.
The table below compares these situations. It is for information only. It does not replace a medical evaluation.
| Situation | Possible Signs | What to Do |
|---|---|---|
| Suspected Withdrawal<br>(After stopping regular use) | Anxiety, trouble sleeping, shaking, sweating, fast heart rate, or confusion. Symptoms often start within hours of the last dose.<br><br>Note: This list covers common GHB withdrawal symptoms but cannot confirm a diagnosis. | If there is a seizure, severe confusion, hallucinations, a high fever or racing heart, call 911 or go to the nearest emergency room now. For other suspected withdrawal, contact a doctor or treatment program promptly; do not manage severe withdrawal at home. |
| Suspected Intoxication<br>(After recent use) | Drowsiness, slurred speech, loss of coordination, nausea, or vomiting.<br><br>Note: These are potential GHB intoxication warning signs but vary by person and dose. | Stay with the person. Watch their breathing closely. If they cannot be woken up or have trouble breathing, call 911 or go to the nearest emergency room now. |
| Possible Coma<br>(Profound unconsciousness) | The person cannot be woken up by shouting or gentle shaking. Breathing may be very slow or irregular. | Call 911 or go to the nearest emergency room now. A coma is a medical emergency. It is not a safe state to sleep through. |
No Specific Reversal Agent
There is no specific medication that reverses the effects of GHB in the body. Do not attempt any home remedies or "reversals." If you suspect poisoning from GHB or related substances, call 911 or go to the nearest emergency room now. Emergency responders can help keep airways open and monitor vital signs while the substance wears off.
What Supervised Medical Care Can Involve
Medical help for this condition means working with a team. They watch for changes as they happen. They base this choice on specific health needs.[2] This approach helps ensure sedative withdrawal safety. It matches care to the actual risks involved.
- Check your full picture. A clinician looks at your symptoms and medical history. They also check recent substance use. They see if you used other substances with GHB.
- Choose the right setting. The care team decides if you need hospital-level care or other support. If severe or complicated withdrawal is a risk, they first check if outpatient care is safe.[1]
- Monitor and treat under supervision. The team checks vital signs and mental status regularly.
- Reassess and plan next steps. As your body adjusts, the team updates your care plan. They prepare you for continuing treatment after the acute phase ends.
Withdrawing from more than one substance can make care more complex.[1] In these cases, the most acute problem often sets the level of care needed.[1]
If you or someone else has a seizure, severe confusion, hallucinations, a high fever, or a racing heart during withdrawal, call 911 or go to the nearest emergency room now.

Other Questions About GHB's Effects
You may have heard claims about how GHB affects the brain, hormones, or sleep. It is important to separate what research suggests from what is proven. No single study can predict how your body will react.
Cognition and Testosterone
Research on GHB and testosterone is limited. Some animal studies suggest GHB can suppress testosterone production, but human data is sparse and inconsistent. There is no strong evidence that GHB use reliably lowers testosterone in humans. If you notice physical changes, talk with a doctor. They can check what is happening in your body.
Regarding cognition, studies report that GHB can cause short-term memory impairment and confusion, especially during intoxication or withdrawal. However, evidence for long-term cognitive deficits in humans is mixed. Some research suggests potential issues with attention and executive function, but these findings are not definitive for all users. Results vary based on health history and usage patterns. If you notice new memory problems, talk with a doctor.
REM Sleep
Research indicates that GHB generally decreases REM sleep and increases deep sleep (slow-wave sleep). It is not accurate to claim GHB increases REM sleep for all users. In fact, abrupt cessation after heavy use can lead to a rebound increase in REM sleep, which may contribute to vivid dreams or insomnia. Sleep patterns depend on many factors, like dosage and timing. If you struggle with sleep quality or feel very tired by day, tell a provider. They can help you understand your specific sleep needs safely.
A Safer Next Step: Non-Diagnostic Self-Check
This check helps you decide on next steps. It is not a diagnosis. It does not pick a level of care. If you see danger signs, do not wait for a score. Any danger sign overrides the rest of this check.
If someone is unresponsive, has breathing problems, or may have overdosed, call 911 or go to the nearest emergency room now. If you have a seizure, severe confusion, hallucinations, a high fever or racing heart during withdrawal, call 911 or go to the nearest emergency room now. For suicidal thoughts, also call or text 988.
What Is the Safest Next Step?
This self-check is for information only and isn't a diagnosis. Danger signs override every score.
Find U.S. Support and Prepare to Ask for Help
If you are not in immediate danger, you can call the SAMHSA National Helpline. It is free and confidential. It works 24 hours a day. It offers treatment referral and information about mental and substance use disorders in English and Spanish.[3] This is a good first step for finding medical help for this condition.
This helpline is not 911. You call 911 for emergencies. If there is immediate danger, call 911 or go to the nearest emergency room now. If you have thoughts of suicide or self-harm, call 911 or go to the nearest emergency room now, and call or text 988 as additional support.[4]
