Sodium Oxibate Normon contains the active ingredient sodium oxibate. Sodium Oxibate Normon acts by consolidating nocturnal sleep, although its exact mechanism of action is unknown.

Sodium Oxibate Normon is used to treat narcolepsy with cataplexy in adults, adolescents, and children aged 7 years and older.

Narcolepsy is a sleep disorder that may include attacks of sleep during hours when normally awake, as well as cataplexy, sleep paralysis, hallucinations, and insomnia. Cataplexy is the sudden onset of muscle weakness or paralysis without loss of consciousness, in response to a sudden emotional reaction such as anger, fear, joy, laughter, or surprise.

• if you are receiving treatment with opioid or barbiturate medicines.

Consult your doctor or pharmacist before starting to take Sodium Oxibate Normon.

• if you have respiratory or pulmonary problems (and especially if you are obese), as Sodium Oxibate Normon may cause breathing difficulties;
• if you have or have had depression, suicidal thoughts, anxiety, psychosis (a mental disorder that may involve hallucinations, incoherent speech, or disorganized and agitated behavior) or bipolar disorder;
• if you have heart failure, high blood pressure, liver or kidney problems, your doctor may need to adjust your dose;
• if you have previously consumed drugs or abused medicines;
• if you have epilepsy, as Sodium Oxibate Normon is not recommended for use in this condition;

If you have any of these problems, inform your doctor before taking Sodium Oxibate Normon.

If you experience nocturnal enuresis and incontinence (both urinary and fecal), confusion, hallucinations, sleepwalking episodes, or abnormal thinking while taking Sodium Oxibate Normon, inform your doctor immediately. Although these effects are rare, they are usually mild to moderate in nature.

In elderly patients, your doctor will closely monitor your progress to check if Sodium Oxibate Normon produces the desired effects.

Sodium Oxibate Normon has a well-known potential for abuse. Cases of dependence have been reported after illicit use of sodium oxibate.

Your doctor will ask if you have consumed any drugs before starting to take Sodium Oxibate Normon and while taking this medicine.

Children and Adolescents

Sodium Oxibate Normon can be taken by adolescents and children aged 7 years or older who weigh more than 15 kg.

Sodium Oxibate Normon should not be taken by children under 7 years of age or who weigh less than 15 kg.

If you are a child or adolescent, your doctor will monitor your body weight regularly.

While your doctor is adjusting the dose, which may take several weeks, parents/caregivers should carefully monitor the child's breathing during the 2 hours after ingesting sodium oxibate to evaluate if there are any breathing abnormalities; for example, interruptions in breathing while sleeping, noisy breathing, and a blue color on the lips and face. If breathing abnormalities are observed, seek medical assistance and inform your doctor as soon as possible. If any abnormalities are observed after the first dose, do not administer the second dose. If no abnormalities are observed, the second dose can be administered. The second dose should not be administered before 2.5 hours or after 4 hours after the administration of the first dose.

If you have had or are experiencing unpleasant sensations, especially if you feel very sad or have lost interest in life, it is essential to inform your doctor or caregiver.

Use of Sodium Oxibate with Other Medicines

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medicine.

In particular, Sodium Oxibate Normon should not be used with sleep-inducing medicines and medicines that reduce the activity of the Central Nervous System (the Central Nervous System is the part of the body composed of the brain and spinal cord):

You should also inform your doctor or pharmacist if you are using any of the following types of medicines:

• antidepressants
• medicines that can be metabolized in a similar way by the body (e.g., valproate, phenytoin, or ethosuximide, which are used to treat epilepsy)

In pediatric patients, doctors, parents, or caregivers are warned that the waiting time for activities requiring mental alertness, motor coordination, or activities that may pose a physical risk may be more than 6 hours, depending on individual sensitivity.

Instructions for diluting Oxibato de sodio Normon

The following instructions explain how to prepare Oxibato de sodio Normon. Read the instructions carefully and follow them step by step. Do not allow children to prepare Oxibato de sodio Normon.

To help you, the Oxibato de sodio Normon packaging contains 1 bottle of medication, a graduated syringe, and two dosing vials with child-resistant safety caps.

Step 1

• Remove the cap from the bottle by pressing down and unscrewing it in a counterclockwise direction (to the left).
• After removing the cap, place the bottle upright on a table.
• While holding the bottle upright, insert the pressure adapter into the neck of the bottle. This should only be done the first time the bottle is opened. The adapter can be left in the bottle for subsequent uses.

• Next, insert the tip of the graduated syringe into the center of the opening of the bottle and press firmly (See Figure 1).

Step 2

• While holding the bottle and syringe in one hand, prepare the prescribed dose with the other hand by pulling the plunger. NOTE: The medication will not flow into the syringe unless you keep the bottle upright (See Figure 2).

Step 3

• Remove the syringe from the center of the opening of the bottle.
• Empty the medication from the syringe into one of the dosing vials provided by pushing the plunger (See Figure 3). Repeat this step for the second dosing vial.
• Add approximately 60 ml of water to each dosing vial (60 ml is approximately 4 tablespoons).

Step 4

• Place the caps on the dosing vials and turn each cap clockwise (to the right) until you feel the click and close it in the child-resistant position (See Figure 4).
• Flush the syringe with water.

Just before going to bed:

• Adult patients should place their second dose near their bed.

• Parents or caregivers of adolescents and children aged 7 years or more should not leave the second dose near the child's bed or within their reach.
• You may need an alarm clock to ensure that you wake up to take your second dose, not before 2.5 hours and not later than 4 hours after your first dose.

Next:

• Remove the cap from the first dosing vial by pressing on the child-resistant safety cap and turning it counterclockwise (to the left).

• Drink the first dose while sitting in bed, cap the vial, and then go to bed immediately. In the case of children who sleep for more than 8 hours but less than 12, the first dose can be administered after the child has slept for 1 to 2 hours.

• When you wake up or wake the child between 2.5 and 4 hours later, remove the cap from the second dosing vial. While sitting in bed, drink the second dose just before going back to bed to continue sleeping. Cap the second vial.
