WHAT XYREM IS AND WHAT IT IS USED FOR
Xyrem contains the active substance sodium oxybate. Xyrem works by
consolidating night-time sleep,
though its exact mechanism of action is unknown.
Xyrem is used to treat narcolepsy with cataplexy in adults,
adolescents and children from 7 years of
age.
Narcolepsy is a sleep disorder that may include attacks of sleep
during normal waking hours, as well
as cataplexy, sleep paralysis, hallucinations and poor sleep.
Cataplexy is the onset of sudden muscle
weakness or paralysis without losing consciousness, in response to a
sudden emotional reaction such
as anger, fear, joy, laughter or surprise.

Treatment of narcolepsy with cataplexy in adult patients, adolescents
and children from the age of 7

4.2
POSOLOGY AND METHOD OF ADMINISTRATION
Treatment should be initiated by and remain under the guidance of a
physician experienced in the
treatment of narcolepsy. Physicians should strictly adhere to the
contraindications, warnings and
precautions.
Posology
Adult
The recommended starting dose is 4.5 g/day sodium oxybate divided into
two equal doses of
2.25 g/dose. The dose should be titrated to effect based on efficacy
and tolerability (see section 4.4) up
to a maximum of 9 g/day divided into two equal doses of 4.5 g/dose by
adjusting up or down in dose
increments of 1.5 g/day (i.e. 0.75 g/dose). A minimum of one to two
weeks is recommended between
dose increments. The dose of 9 g/day should not be exceeded due to the
possible occurrence of severe
symptoms at doses of 18 g/day or above (see section 4.4).
_ _
Single doses of 4.5 g should not be given unless the patient has been
titrated previously to that dose
level.
If sodium oxybate and valproate are used concomitantly (see section
4.5), a decrease in sodium
oxybate dose by 20% is recommended. The recommended starting dose for
sodium oxybate, when
used concomitantly with valproate, is 3.6 g per day administered
orally in two equal divided doses of
approximately 1.8 g. If concomitant use is warranted, patient response
and tolerability should be
monitored and dose should be adapted accordingly (see section 4.4).
Discontinuation of Xyrem
The discontinuation effects of sodium oxybate have not been
systematically evaluated in controlled
clinical trials (see sectio
