1. What is Stilnox and what is it used for

Stilnox is available in the form of coated tablets and contains the active substance zolpidem.
Zolpidem belongs to a group of sedative and hypnotic medicines.
The medicine facilitates falling asleep, reduces the number of nighttime awakenings, prolongs sleep duration, and improves its quality.
Stilnox is used for short-term treatment of insomnia in patients over 18 years of age when insomnia causes the patient disabling weakness or severe suffering.
Do not use for a long time. Treatment should last as short as possible, as the risk of dependence increases with the duration of treatment.

2. Important information before taking Stilnox

Do not take Stilnox if:

• you are allergic to zolpidem or any of the other ingredients of this medicine (listed in section 6)
• you have severe liver impairment
• you have sleep apnea syndrome
• you have acute and/or severe respiratory failure
• you have myasthenia gravis
• you are taking long-term therapy. Treatment should last as short as possible, as the risk of dependence increases with the duration of treatment.
• you have ever experienced sleepwalking or other unusual behaviors during sleep (such as driving, eating, making phone calls, or having sex, etc.) when you did not wake up completely after taking Stilnox or another medicine containing zolpidem.

Warnings and precautions

Before starting treatment with Stilnox, you should discuss it with your doctor or pharmacist.
In each case, you should determine, if possible, the causes of insomnia and eliminate the factors that cause it, if possible, before the doctor recommends taking a sleeping medicine.
Persistence of insomnia after 7-14 days of treatment may indicate the existence of primary mental or physical disorders that require diagnosis and evaluation by a doctor at regular intervals.
Respiratory failure:
Due to the fact that sleeping medicines can inhibit the activity of the respiratory center, caution should be exercised when taking Stilnox in patients with respiratory function disorders (see section 4).
Liver function disorders:
Liver function disorders - see section 3. How to take Stilnox:
Stilnox should not be taken in patients with severe liver impairment. Taking Stilnox in patients with severe liver impairment may lead to encephalopathy - a disorder of the central nervous system caused by liver failure (see section 2. "Important information before taking Stilnox").
Elderly or weakened patients:
Elderly or weakened patients should take a lower dose of the medicine, see section 3.
Mental illnesses:
Sleeping medicines, such as Stilnox, are not recommended for initial treatment of mental illnesses.
Psychomotor disorders the next day (see also "Driving and operating machinery"):
Like other sleeping medicines, zolpidem has a sedative effect on the central nervous system.
The next day after taking Stilnox, the risk of psychomotor disorders, including impaired driving ability, may be increased if:

• The patient took the medicine less than 8 hours before activities that require increased alertness.
• The patient took a higher dose than recommended.
• The patient took zolpidem while being treated with other medicines that have a sedative effect on the central nervous system or other medicines that increase the concentration of zolpidem in the blood, while consuming alcohol or taking prohibited substances.

You should take a single dose directly before bedtime.
Do not take another dose on the same night.
Amnesia:
Sedative and sleeping medicines can cause anterograde amnesia. It usually occurs a few hours after taking the medicine. To reduce the risk, the patient should have the opportunity for uninterrupted sleep lasting 8 hours.
Suicidal thoughts, suicide attempts, suicide, and depression:
Some studies have shown an increased risk of suicidal thoughts, suicide attempts, and suicide in patients taking certain sedative and sleeping medicines, including this medicine. However, it has not been determined whether this is caused by taking the medicine or other factors. If the patient has suicidal thoughts, they should contact their doctor as soon as possible to receive medical advice.
Although no clinically significant interactions have been found between zolpidem and selective serotonin reuptake inhibitors (see section: Stilnox and other medicines) and other sedative and sleeping medicines, caution should be exercised when taking zolpidem as well as other sedative and sleeping medicines in patients with symptoms of depression.
In this group of patients, suicidal tendencies may occur, so the doctor should prescribe the smallest dose of the medicine to prevent intentional overdose. Previously experienced depression may manifest during zolpidem treatment. Since insomnia can be a symptom of depression, in case of persistent insomnia, the doctor should re-examine the patient.
Other psychological reactions and "paradoxical" reactions:
The use of sedative and sleeping medicines, such as zolpidem, may be accompanied by other psychological reactions and paradoxical reactions, such as anxiety, increased insomnia, excitement, irritability, aggression, delusions, outbursts of anger, nightmares, hallucinations, inadequate behavior, and other behavioral disorders.
In such cases, treatment should be discontinued. The occurrence of such reactions is more likely in elderly patients.
Somnambulism and similar behaviors:
Stilnox may cause sleepwalking or other unusual behaviors during sleep (such as driving, eating, making phone calls, or having sex, etc.) when the patient has not woken up completely. The next morning, the patient may not remember the activities performed during the night. If any of the above behaviors occur in the patient, treatment with Stilnox should be discontinued immediately, and the patient should contact their doctor, as such behaviors during sleep can pose a serious risk of injury to the patient or their environment.
Consuming alcohol or taking other medicines that cause drowsiness at the same time as Stilnox may increase the risk of such behaviors during sleep, as well as taking zolpidem in doses exceeding the maximum recommended dose.
Tolerance:
In the case of long-term use of sedative and sleeping medicines containing zolpidem, including Stilnox, for more than a few weeks, a decrease in their sedative effect may occur.
Dependence:
Taking Stilnox may lead to misuse of the medicine and/or development of psychological or physical dependence.
If the patient has ever had mental disorders, misused or been dependent on alcohol, prohibited substances, or medicines, they should tell their doctor. The risk of dependence is higher when Stilnox is taken for more than 4 weeks and in patients with mental disorders and/or a history of alcohol, substance, or medicine misuse.
In cases where physical dependence has developed, sudden discontinuation of treatment will be accompanied by withdrawal symptoms. These may include headaches and muscle pain, increased anxiety and tension, restlessness, confusion, and irritability. In severe cases, symptoms such as derealization, depersonalization, increased hearing acuity, numbness and tingling of limbs, hypersensitivity to light, noise, and touch, hallucinations, and seizures may occur.
Rebound insomnia (rebound insomnia):
After discontinuation of sleeping medicine, a transient syndrome may occur, in which the symptoms that led to the initiation of sedative and sleeping medicine treatment recur in an intensified form.
These symptoms may be accompanied by other reactions, such as mood changes, anxiety, and fear.
It is essential to inform the patient about the possibility of rebound insomnia and take appropriate measures to minimize the risk of anxiety and other symptoms if they occur during treatment discontinuation.
In the case of short-acting sedative and sleeping medicines, the withdrawal syndrome may occur between doses.
Severe injuries:
The medicine may cause drowsiness and impaired consciousness, which can lead to falls and, consequently, severe injuries.
Patients with a prolonged QT interval syndrome:
The potential consequences of taking zolpidem in patients with a congenital prolonged QT interval syndrome are unknown. As a precautionary measure, the doctor should carefully weigh the benefits and risks of zolpidem treatment in patients with a diagnosed, congenital prolonged QT interval syndrome.

Children and adolescents

Stilnox should not be taken in children and adolescents under 18 years of age, as the safety and efficacy of zolpidem have not been established in this age group.

Stilnox and other medicines

Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or might take.
Alcohol:
Concomitant use of alcohol is not recommended. Zolpidem's sedative effect may be enhanced during concomitant alcohol consumption. This may affect the ability to drive and operate machinery.
Medicines with a sedative effect on the central nervous system:
When taking zolpidem with certain medicines, sedation and psychomotor disorders the next day, including impaired driving ability, may be enhanced. These medicines include:

• Medicines used to treat certain mental health disorders (antipsychotics).
• Medicines used to treat sleep disorders (sleeping medicines).
• Sedative or anxiolytic medicines.
• Medicines used to treat depression.
• Medicines used to treat moderate to severe pain (opioid analgesics).
• Medicines used to treat epilepsy.
• Medicines used for anesthesia.
• Medicines used to treat hay fever, skin rash, or other allergies that may cause drowsiness in the patient (sedating antihistamines).

When taking zolpidem with antidepressant medicines, including bupropion, desipramine, fluoxetine, sertraline, and venlafaxine, the patient may see things that are not real (visual hallucinations).
Zolpidem should not be taken with fluvoxamine or ciprofloxacin.
Concomitant use of Stilnox and opioids (strong painkillers, substitution therapy medicines, and some cough medicines) increases the risk of drowsiness, breathing difficulties (respiratory failure), coma, and may be fatal. Therefore, concomitant use of these medicines should only be considered when other treatment options are not possible.
However, when the doctor prescribes Stilnox together with opioids, the dose and duration of concomitant use should be limited by the doctor. You should tell your doctor about all opioid medicines you are taking and strictly follow the dosage instructions. It may be helpful to inform your friends and family to be aware of the above signs and symptoms.
If these symptoms occur, you should contact your doctor.
Cytochrome P450 inhibitors and inducers:
Certain medicines that inhibit liver enzymes (especially cytochrome P450) may enhance the effect of certain sleeping medicines, such as zolpidem.
Concomitantly used CYP3A4 inducers, such as rifampicin and St. John's Wort, decrease the pharmacodynamic effect of zolpidem.
When concomitantly used with St. John's Wort, the concentration of zolpidem in the blood may decrease. Zolpidem should not be taken with St. John's Wort.
Concomitant administration of zolpidem with ketoconazole (at a dose of 200 mg twice a day) may enhance its sedative effect.
Other medicines:
No significant pharmacokinetic interactions have been observed when zolpidem is concomitantly used with warfarin, digoxin, and ranitidine.

Stilnox with food and drink

The medicine should be taken directly before going to bed or after lying down.

Pregnancy and breastfeeding

Pregnancy
Stilnox is not recommended during pregnancy. If you are pregnant, think you may be pregnant, or plan to have a baby, you should consult your doctor before taking this medicine.
The medicine used during pregnancy may affect the baby. Some studies have shown an increased risk of cleft lip and palate (sometimes called "hare lip") in newborns.
There may be decreased fetal movement and variable fetal heart rate if the mother takes Stilnox in the second and/or third trimester of pregnancy.
If the patient takes Stilnox in late pregnancy or during childbirth, the baby may show muscle weakness, decreased body temperature, feeding difficulties, and breathing difficulties (respiratory depression).
If the patient regularly takes Stilnox in late pregnancy, the baby may develop physical dependence, and withdrawal symptoms may occur, such as excitement or seizures. In such a case, the newborn should be closely monitored in the postnatal period.
Breastfeeding
Stilnox should not be taken during breastfeeding, as a small amount of the medicine passes into breast milk.

Driving and operating machinery

Stilnox has a major impact on the ability to drive and operate machinery and may cause events such as "falling asleep at the wheel". The next day after taking Stilnox (like other sleeping medicines), it may happen that:

• the patient feels drowsy, sleepy, dizzy, or disoriented,
• the patient needs more time to make quick decisions (impaired reflexes),
• the patient may see double or blurred vision,
• the patient may be less alert.

To minimize the risk of the above events, it is recommended to maintain an interval of at least 8 hours between taking zolpidem and driving, operating machinery, or working at heights.
Do not consume alcohol or psychoactive substances while taking Stilnox, as this may enhance the above effects.

Stilnox contains lactose monohydrate

Stilnox contains lactose monohydrate. If you have been diagnosed with intolerance to some sugars, you should consult your doctor before taking the medicine.

Stilnox contains sodium

The medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means the medicine is considered "sodium-free".

3. How to take Stilnox

This medicine should be taken as directed by your doctor. If you have any doubts, you should consult your doctor or pharmacist.
The medicine should be taken orally.
Stilnox acts quickly, so it should be taken directly before going to bed or after lying down.
Like all sleeping medicines, long-term use of Stilnox is not recommended. The recommended treatment duration should not exceed 4 weeks.
In some cases, it may be necessary to extend the treatment period by the doctor beyond the maximum recommended duration, but this should not be done without re-evaluating the patient's clinical condition.
Adults:
The recommended dose of Stilnox is 10 mg (1 tablet) per day (24 hours). Your doctor may prescribe a lower dose for some patients.
Stilnox should be taken:

• in a single dose,
• directly before bedtime.

The patient must maintain a period of at least 8 hours between taking the medicine and starting activities that require increased concentration.
Do not exceed the dose of 10 mg per 24 hours.
Elderly patients:
In elderly or weakened patients who may be particularly sensitive to zolpidem, a dose of 5 mg of Stilnox (half a tablet) is recommended. In this group of patients, the daily dose should not exceed 10 mg.
Patients with liver function disorders:
In patients with liver function disorders, the doctor will reduce the initial dose to 5 mg, exercising particular caution, especially in elderly patients.
In adults (under 65 years of age), the doctor may increase the dose to 10 mg if the patient's condition is good and the medicine is well tolerated, but only if the medicine is ineffective at a lower dose.
Children and adolescents:
The safety and efficacy of zolpidem have not been established in children and adolescents under 18 years of age. Therefore, Stilnox should not be taken in this group of patients (see section 2).
If you feel that the effect of Stilnox is too strong or too weak, you should consult your doctor.

Taking a higher dose of Stilnox than recommended

If you have taken a higher dose of the medicine than recommended, you should contact your doctor immediately.
In cases of zolpidem overdose, either alone or in combination with other central nervous system depressants (including alcohol), impaired consciousness of varying degrees has been observed, from increased drowsiness to coma, as well as very severe symptoms, including death.
After an overdose of zolpidem, symptomatic and supportive treatment is recommended; gastric lavage or activated charcoal may be administered to reduce absorption of the medicine from the gastrointestinal tract.
Sedative medicines should be discontinued, even in case of agitation.
In case of severe symptoms, the doctor will consider administering flumazenil, but the use of flumazenil may cause neurological symptoms (seizures).
Zolpidem is not eliminated from the body by hemodialysis.

Missing a dose of Stilnox

You should take the medicine the next day at the usual time. Do not take two doses of the medicine at the same time or in a short period.

Stopping treatment with Stilnox

Do not stop taking Stilnox abruptly, as this increases the risk of withdrawal symptoms. Your doctor will inform you about how to end the treatment by gradually reducing the dose.
If you have any further doubts about taking this medicine, you should consult your doctor or pharmacist.

4. Possible side effects
