Symptoms of GHB Use

GHB produces feelings of relaxation and tranquility. It may also cause fatigue and feelings of being uninhibited.

At higher doses, GHB may cause

  • Dizziness

  • Loss of coordination

  • Nausea

  • Vomiting

At high doses, GHB can also slow breathing and cause seizures and coma, sometimes leading to death. Combining GHB and any other sedatives, especially alcohol, is extremely dangerous. Most deaths have occurred when GHB was taken with alcohol.

Withdrawal symptoms occur if GHB is not taken for several days after previous frequent use. Withdrawal symptoms are similar to those of alcohol withdrawal (including tremor, headache, sweating, nausea, and seizures) and can be life threatening.

Diagnosis of GHB Use

  • A doctor's evaluation

Diagnosis is based on symptoms in people known to have used GHB. No readily available tests can confirm the use of GHB.

Treatment of GHB Use

  • Observation and monitoring until the person is sober

  • Sometimes assistance with breathing

Treatment complications from GHB use is directed at symptoms. A ventilator may be needed if breathing is affected. Most people recover rapidly.
