Overview InformationGamma hydroxybutyrate (GHB) is a chemical found in the brain and other areas of the body. It can also be made in a laboratory.
GHB used to be available as a dietary supplement in the U.S., but it was taken off the market in 1990 because of safety concerns. GHB and two closely related chemicals, gamma butyrolactone (GBL) and butanediol (BD), were linked to 3 deaths and 122 serious side effects. Nevertheless, secret production and sales of GHB continued, often on the Internet. Continued interest in GHB might have been fueled by GHB's reputation as a "date rape" drug. Under the Date-Rape Drug Prohibition Act of 2000, regulation tightened. GHB was classified as a Schedule I controlled substance, like heroin. It is now illegal for Americans to produce, sell, or possess GHB except for medical use. A prescription form of GHB remains available, but the only legal access to this drug is through a physician or other healthcare provider who is licensed to prescribe medications.
GHB is used for depression, weight loss, muscle building, and relief of some fibromyalgia symptoms including pain, fatigue, and sleep problems. It is also used as an alternative to the dietary supplement L-tryptophan for promoting relaxation and sleepiness. People who are addicted to alcohol or narcotic drugs sometimes use GHB to help them manage withdrawal symptoms. It is also used to cause sexual arousal.
The prescription form of GHB has been approved by the U.S. Food and Drug Administration (FDA) for treatment of narcolepsy, a sleep disorder caused by the brain's inability to regulate sleep-wake cycles. People with narcolepsy experience irresistible bouts of daytime sleep. They can also experience muscle control problems, paralysis, and hallucinations. GHB is available under the generic name sodium oxybate and trade name Xyrem (Orphan Medical) for the treatment of paralysis associated with narcolepsy. It is a Schedule III Controlled Substance, which means extra paperwork is necessary when this drug is prescribed, and prescriptions for this drug receive special scrutiny from regulators.
Health care providers use GHB intravenously to numb pain and reduce pressure inside the head after a head injury.
How does it work?The natural function of GHB in the body might be to slow down brain activity during sleep. GHB affects several nerve pathways in the brain, including activating the body's pain-killing (opioid) system and raising levels of growth hormone.
Uses & Effectiveness
Possibly Effective for
- Alcohol dependence and withdrawal. Taking GHB seems to reduce symptoms of alcohol withdrawal and prevent relapse in people who already completed detox.
- Treatment of loss of muscle control and weakness associated with a condition called narcolepsy. Taking GHB seems to help people with narcolepsy sleep at night so they are less likely to feel sleepy during the day. GHB also seems to help reduce the temporary paralysis that sometimes goes along with narcolepsy.
- Fibromyalgia. Taking GHB seems to reduce pain, fatigue, and sleep problems associated with fibromyalgia
- Withdrawal from heroin, opium, morphine, and other opiate drugs. Taking GHB seems to reduce withdrawal symptoms in heroin addicts and methadone-maintained addicts.
Insufficient Evidence for
- Reducing weight.
- Enhancing muscle growth.
- Causing sexual arousal.
- Reducing pressure in the brain caused by head injury.
- Other conditions.
Side Effects & SafetyThe prescription medication GHB (sodium oxybate) is POSSIBLY SAFE for adults who are taking it under close medical supervision for symptoms of a condition called narcolepsy. GHB is also POSSIBLY SAFE when given by IV under close medical supervision, short-term.
GHB is UNSAFE and illegal for use as a dietary supplement. Use of GHB, or the closely related gamma butyrolactone (GBL) and butanediol (BD), has been linked to at least three deaths and 122 cases of serious side effects. GHB can cause many serious side effects including headaches, hallucinations, dizziness, confusion, nausea, vomiting, drowsiness, agitation, diarrhea, sexual arousal, numbing of legs, vision problems, tightness of chest, changes in heart rate, mental changes, combativeness, memory loss, serious breathing and heart problems, seizures, coma, and death. GHB can be addictive. Long-term use may lead to withdrawal symptoms that are serious enough to require hospitalization.
GHB also has some major interactions with prescription medications.
Special Precautions & Warnings:Pregnancy and breast-feeding: GHB is UNSAFE. Don't use GHB if you are pregnant or breast-feeding. It's been linked with life-threatening side effects.
Slow heart rate (bradycardia): GHB should be avoided since it can cause bradycardia.
Epilepsy: GHB might cause seizures in people with epilepsy. Avoid use.
High blood pressure: GHB might raise blood pressure. Avoid use.
Surgery: GHB can affect the central nervous system. There is a concern that it might cause too much sleepiness if it is used along with anesthesia and other nerve-numbing medications used during and after surgery. Stop using GHB at least 2 weeks before a scheduled surgery.
Do not take this combination
Alcohol interacts with GAMMA-HYDROXYBUTYRATE
Alcohol can cause sleepiness and drowsiness. Taking GHB along with alcohol might greatly increase sleepiness and drowsiness caused by alcohol. Taking GHB along with alcohol can lead to serious side effects. Do not take GHB if you have been drinking.
Amphetamines interacts with GAMMA-HYDROXYBUTYRATE
Amphetamines are drugs that can speed up your nervous system. GHB can slow down your nervous system. Taking GHB along with amphetamines can lead to serious side effects.
Haloperidol (Haldol) interacts with GAMMA-HYDROXYBUTYRATE
GHB can affect the brain. Haloperidol (Haldol) can also affect the brain. Taking haloperidol (Haldol) along with GHB might cause serious side effects.
Medications for mental conditions (Antipsychotic drugs) interacts with GAMMA-HYDROXYBUTYRATE
GHB can affect the brain. Medications for mental conditions also affect the brain. Taking GHB along with medications for mental conditions might increase the effects and serious side effects of GHB. Do not take GHB if you are taking medications for a mental condition.<br><nb>Some of these medications include fluphenazine (Permitil, Prolixin), haloperidol (Haldol), chlorpromazine (Thorazine), prochlorperazine (Compazine), thioridazine (Mellaril), trifluoperazine (Stelazine), and others.
Medications used to prevent seizures (Anticonvulsants) interacts with GAMMA-HYDROXYBUTYRATE
