Sodium Oxybate and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
Sodium oxybate falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.
Sodium Oxybate and Lactation
It is not known if sodium oxybate crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using sodium oxybate.
Sodium Oxybate Usage
- Take sodium oxybate exactly as prescribed by your doctor.
- Take sodium oxybate two times each night or as directed by your doctor. Prepare your sodium oxybate doses before going to bed. Take the first dose at bedtime while in bed. Take your second dose 2 ½ (2.5) to 4 hours after the first dose. You should set an alarm clock to make sure you wake up to take the second dose. If you miss the second dose, skip that dose and do not take sodium oxybate again until the next night. Never take two sodium oxybate doses at once.
- Allow at least 2 hours after eating before taking sodium oxybate. Food will lower the amount of sodium oxybate that passes into your body.
- In case of accidental overdose, call 911.
- You should see your doctor every 3 months for a check-up while taking sodium oxybate. Your doctor should check your response to sodium oxybate treatment, including improvement in your symptoms and if you are having any side effects.
All sodium oxybate prescriptions are processed by a central, mail order pharmacy.
Directions for Using sodium oxybate

Sodium Oxybate FDA Warning
WARNING: Central nervous system depressant with abuse potential. Should not be used with alcohol or other CNS depressants.
Sodium oxybate is GHB, a known drug of abuse. Abuse has been associated with some important central nervous system (CNS) adverse events (including death). Even at recommended doses, use has been associated with confusion, depression and other neuropsychiatric events. Reports of respiratory depression occurred in clinical trials. Almost all of the patients who received sodium oxybate during clinical trials were receiving CNS stimulants.
Important CNS adverse events associated with abuse of GHB include seizure, respiratory depression and profound decreases in level of consciousness, with instances of coma and death. For events that occurred outside of clinical trials, in people taking GHB for recreational purposes, the circumstances surrounding the events are often unclear (e.g., dose of GHB taken, the nature and amount of alcohol or any concomitant drugs).
This medication is available through a centralized pharmacy 1-866-XYREM88 (1-866-997-3688). The Success Program provides educational materials to the prescriber and the patient explaining the risks and proper use of sodium oxybate, and the required prescription form. Once it is documented that the patient has read and/or understood the materials, the drug will be shipped to the patient. The Success Program also recommends patient follow-up every 3 months. Physicians are expected to report all serious adverse events to the manufacturer.
