Xyrem Indication

Sodium oxybate belongs to a group of medications known as central nervous system (CNS) depressants. It is used to treat Narcolepsy by reducing the number of cataplexy (weak or paralyzed muscles) attacks. Narcolepsy is a condition that causes daytime excessive sleepiness. At this time, it is not known exactly how Xyrem (Sodium-oxybate) works to reduce cataplexy attacks.

Xyrem (Sodium-oxybate) usually starts to work within the first weeks of treatment, but it may take up to 8 weeks for you and your doctor to find the dose that is best for you.

Xyrem (Sodium-oxybate) may be available under multiple brand names and/or in several different forms. Any specific brand name of Xyrem (Sodium-oxybate) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Xyrem (Sodium-oxybate) may not be used for all of the conditions discussed here.

Your doctor may have suggested Xyrem (Sodium-oxybate) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Xyrem (Sodium-oxybate), speak to your doctor. Do not stop taking Xyrem (Sodium-oxybate) without consulting your doctor.

Do not give Xyrem (Sodium-oxybate) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Xyrem (Sodium-oxybate) if their doctor has not prescribed it.

Xyrem Dosage

The recommended initial dose of sodium oxybate is 4.5 g per night given in 2 equal doses of 2.25 g. The first dose is taken at bedtime and the second dose is taken 2.5 to 4 hours later. Your doctor may adjust the dose (usually every 2 weeks) according to how you respond and the side effects you experience. The maximum dose is 9 g per night.

Food will decrease the amount of sodium oxybate that is absorbed by your body. Therefore, take Xyrem (Sodium-oxybate) at least 2 hours after your last meal prior to bedtime. Take Xyrem (Sodium-oxybate) only at bedtime and while in bed, as it may cause you to fall asleep too quickly. Do not walk around after taking Xyrem (Sodium-oxybate).

You need to take some steps to prepare Xyrem (Sodium-oxybate) before taking it. Before taking Xyrem (Sodium-oxybate), read the Patient Package Insert for information about how to prepare and use Xyrem (Sodium-oxybate) properly. If you are not sure how to prepare or use Xyrem (Sodium-oxybate), talk to your doctor or pharmacist.

There are 2 doses you need to prepare. Prepare both doses before bedtime. Your medication comes with a medication bottle, a measuring device, and 2 dosing cups.

Remove the cap on the medication bottle, insert the measuring device into the centre opening on the top of the medication bottle, and press down firmly. While holding the bottle and measuring device with one hand, draw up the prescribed dose with the other hand by pulling up on the plunger of the measuring device. Keep the medication bottle in the upright position while you are drawing up your dose.

Empty the contents of the measuring device into one of the dosing cups by pushing down on the plunger while holding the measuring device over the dosing cup. Add about 60 mL (2 ounces) of water to the dosing cup.

Repeat this process with the second dosing cup. Place the caps provided on the dosing cups and turn each cap to the right until it clicks and locks into its child – resistant position. Replace the cap on the bottle of medication and store it in a safe place out of the reach of children. Rinse out the liquid measuring device with water.

  1. Right before going to sleep, place your second dose in a secure location near your bed. You may need to set an alarm clock to wake you up for the second dose. Remove the cap from your first dosing cup by pressing down and turning to the left. Drink the entire first dose while sitting in bed, recap the cup, and then lie down right away.
  2. When you wake up 2.5 to 4 hours later, remove the cap from the second dosing cup. While sitting in bed, drink the entire second dose, recap the cup, and then lie down to continue sleeping.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor. Never change the dose of Xyrem (Sodium-oxybate) yourself.

It is important to take Xyrem (Sodium-oxybate) exactly as prescribed by your doctor. If you miss the first dose, take it as soon as you remember and then continue with your regular dosing schedule (make sure that your second dose is taken at least 2.5 hours after the first dose). If you miss the second dose of Xyrem (Sodium-oxybate), skip the missed dose and do not take it again until the next night. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Xyrem (Sodium-oxybate) at room temperature in the original bottle in a safe and secure place (locked up if appropriate), and keep it out of the reach of children and pets. After adding water, the medication should be used within 24 hours. Any unused medication should be returned to the pharmacy for proper disposal. Do not pour it down the drain. Always place your nightly doses of Xyrem (Sodium-oxybate) safely out of the reach of children and pets.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
