What is sodium oxybate?
Sodium oxybate is also known as GHB, a known street drug of abuse. Because of the potential for abuse and serious side effects, sodium oxybate is available only from a certified pharmacy under a special program called Xyrem Success Program. Your doctor must be registered in the program in order to prescribe sodium oxybate for you.
Sodium oxybate may also be used for purposes not listed in this medication guide.
Sodium oxybate can slow or stop your breathing, even at regular doses or if you are also taking stimulant medicines.
Fatal side effects can occur if you use this medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Avoid taking other medicines that make you sleepy or slow your breathing. This includes cold or allergy medicine, opioid pain medicine, sedatives, muscle relaxants, seizure medicine, or medicine for depression, anxiety, or mental illness. Your doctor may need to change your treatment plan if you need to use any of these other medicines.
Misuse of sodium oxybate can cause breathing problems, seizure, loss of consciousness, or death. Sodium oxybate is available only from a certified pharmacy. Do not allow anyone else to use your medication.

How should I take sodium oxybate?
Follow all directions on your prescription label. Sodium oxybate can slow or stop your breathing, even at regular doses or if you are also taking stimulant medicine. Never use sodium oxybate in larger amounts, or for longer than prescribed.
Sodium oxybate may be habit-forming. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. Misuse of this medicine can cause breathing problems, seizure, loss of consciousness, or death. Selling or giving away sodium oxybate is against the law.
Read all patient information, medication guides, and instruction sheets provided to you. Do not allow anyone else to use your medication.
Take sodium oxybate on an empty stomach at least 2 hours after a meal. It is important to take sodium oxybate at the same time each night.
Sodium oxybate must be taken at bedtime and again two and a half to four hours later. This medicine works very fast and should be taken while you are sitting in bed ready for sleep. Prepare both doses while you are getting ready for bed. Place the second dose next to your bed so you can take it without getting up. You will most likely need to set an alarm to awaken for the second dose.
Each dose of sodium oxybate must be mixed with two ounces (one quarter cup) of water in the child-resistant dosing cups provided with the medication. Both doses must be used within the same night. Throw away any sodium oxybate dose that has been mixed with water but not used within 24 hours of mixing.
Do not stop using sodium oxybate suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using sodium oxybate.
Your doctor will need to check your progress every 3 months. If you need surgery, tell the surgeon ahead of time that you are using sodium oxybate.

Keep track of your medicine. Sodium oxybate is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Do not keep leftover sodium oxybate liquid. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush any unused liquid medicine down the toilet.
What happens if I miss a dose?
Take the missed dose as soon as you remember, but only at bedtime or during your normal sleeping hours. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
