Important safety information:
Sodium Oxybate is a central nervous system (CNS) depressant and has caused changes in alertness (or consciousness) and trouble breathing (respiratory depression). Call your doctor right away if you have any of these serious side effects. These effects happened even when Sodium Oxybate was given in recommended doses. In studies, almost all of the patients with narcolepsy who were given Sodium Oxybate were also taking medication to help them stay awake during the day.
Sodium Oxybate is a form of gamma hydroxybutyrate (GHB). Abuse of GHB, either alone or in combination with other drugs that cause changes in alertness (or consciousness), has caused serious side effects. These effects include seizures, trouble breathing (respiratory depression), very low levels of alertness (consciousness), coma, and death.
Because of these risks, Roxane’s Sodium Oxybate will be available only through the Sodium Oxybate REMS Program. Prescribers and patients must enroll in the program.
Do not take Sodium Oxybate if you take other sleep medicines or sedatives (medicines that cause sleepiness), drink alcohol, or have a rare problem called semialdehyde dehydrogenase deficiency.
Sodium Oxybate is a controlled substance (CIII) because it can be a target for people who abuse prescription medicines or street drugs. Never give your Sodium Oxybate to anyone else because it may cause death or harm them. Selling or giving this medication away is against the law.
Do not drive a car, use heavy machinery, fly an airplane, or do anything that is dangerous or that requires you to be fully awake for at least 6 hours after you take Sodium Oxybate. You should not do these activities until you know how Sodium Oxybate affects you.
Sodium Oxybate can cause serious side effects, including the following:
- Breathing problems, including slower breathing, trouble breathing, and or/short periods of not breathing while sleeping (sleep apnea). People who already have breathing or lung problems have a higher chance of having breathing problems when they use Sodium Oxybate.
- Mental health problems, including confusion, seeing or hearing things that are not real (hallucinations), unusual or disturbing thoughts (abnormal thinking), feeling anxious or upset, depression, or thoughts of killing yourself or trying to kill yourself. Call your doctor right away if you have symptoms of mental health problems.
- Sleepwalking. Sleepwalking can cause injuries. Call your doctor if you start sleepwalking. Your doctor should check you.
Tell your doctor if you are on a salt-restricted diet or if you have high blood pressure, heart failure, or kidney problems. Sodium Oxybate contains a lot of sodium (salt) and may not be right for you.
The most common side effects of Sodium Oxybate include nausea, dizziness, vomiting, bedwetting, and diarrhea. Your side effects may increase when you take higher doses of Sodium Oxybate. Sodium Oxybate can cause physical dependence and craving for the medication when it is not taken as directed. These are not all the possible sid...
