Contents of the pack
Zolpidem Vir belongs to a group of medicines known as benzodiazepine-related drugs used for sleep disorders.
Zolpidem has a calming and sleep-inducing effect. As a result, zolpidem shortens the time it takes to fall asleep, can prevent frequent awakenings during the night, and prolongs the period of deep sleep.
Zolpidem Vir is used for the short-term treatment of insomnia in adults, only when the disorder is severe, disabling, or causing significant distress.
Do not take this medicine for a long time. Treatment should be as short as possible because the risk of dependence increases with the duration of treatment.
Do not take Zolpidem Vir
Warnings and precautions
General
Talk to your doctor or pharmacist before taking zolpidem
The cause of the sleep disturbance should be clear and, if possible, underlying diseases should be treated before prescribing sleeping pills, especially if it has been going on for more than 6 weeks.
If the treatment does not improve the sleep problem after 7-14 days of treatment, further investigation will be necessary. The duration of treatment should be as short as possible and never exceed 4 weeks, including the gradual withdrawal process. This period can only be extended after re-evaluation of the patient's condition.
Special care is required when taking zolpidem,
Children and adolescents < 18 years
Since the safety and efficacy of zolpidem have not been adequately studied, the doctor will not prescribe zolpidem.
Elderly and disabled patients
Older people (> 65 years) or debilitated patients may react especially sensitively to zolpidem. In this case, symptoms of fatigue may persist after waking up. Be careful when getting up at night: there is a risk of falls!
Liver damage
Pay special attention to the recommended dose, as the effects of zolpidem may last longer. Your doctor will regularly monitor your treatment.
Tolerance
Repeated use of zolpidem with other sleeping pills for a period of several weeks may affect its efficacy.
Dependence
Long-term use of zolpidem with other sedatives may lead to physical or psychological dependence. The risk of dependence is greater when zolpidem is used for more than 4 weeks. The risk of abuse or dependence increases with the dose and duration of treatment and is greater in patients with a history of mental disorders and/or alcoholism, illicit substances, or drug use. Inform your doctor if you have had any mental disorder or problems with abuse or dependence on alcohol or drugs.
If physical dependence has developed, sudden interruption of treatment may be accompanied by withdrawal symptoms such as headache, muscle pain, fear, and severe tension, restlessness, confusion, and irritability.
In severe cases, the following symptoms may occur: loss of sense of reality, isolation from others, intensified hearing, sensation of numbness and tingling in arms and legs, hypersensitivity to light, sound, and touch, delirium, or epileptic seizures.
Rebound insomnia
After stopping treatment with zolpidem or other sedatives, symptoms may reappear and worsen. Other reactions may also occur, such as mood changes, fear, and restlessness.
The probability of rebound symptoms is greater when treatment is stopped suddenly. This is why the use of zolpidem should be gradually reduced.
Depression
Like other hypnotic or tranquilizing medicines, zolpidem should be used with caution in patients with symptoms of depressionor anxiety accompanied by depression. In certain circumstances, it may increase depressive symptoms if there is no adequate treatment of the underlying disease with appropriate medications (antidepressants). This may increase the risk of suicide for these patients. Depression may appear previously unrecognized due to zolpidem. Some studies show a higher incidence of suicide or attempted suicide in patients taking certain sleeping pills or sedatives, including zolpidem. However, it has not been established whether this is due to medical treatment or if it may have other causes. Inform your doctor immediately if you have suicidal thoughts (thoughts of harming yourself or suicide) or suicidal behavior.
Memory disorders (amnesia)
Zolpidem may cause memory loss (amnesia). It usually occurs a few hours after taking zolpidem. To minimize this risk, you should ensure that you sleep uninterrupted for at least 8 hours.
Paradoxical psychiatric reactions and contradictory reactions
The following reactions may occur when taking zolpidem: increased sleep disturbances, agitation, irritability, aggressiveness, delirium, restlessness, nightmares, mental disorders, sleepwalking, inappropriate behavior, and other adverse effects on behavior.
The use of zolpidem in elderly patients and in combination with alcohol and other medicines seems to increase the risk of these behaviors. The use of a higher dose of zolpidem than the maximum recommended dose also seems to increase the risk of this behavior.
Sleepwalking and other associated behaviors
Cases of sleepwalking and other associated behaviors, such as "sleep-driving", cooking, and eating, making phone calls, or having sex with amnesia for these events, have been reported in patients who had taken zolpidem and were not fully awake.
Concomitant use with alcohol and other medicines seems to increase the risk of these behaviors. The use of a higher dose than the maximum recommended dose also seems to increase the risk of this behavior.
Discontinuation of zolpidem should be considered for patients who report such behaviors (e.g., sleep-driving), due to the risk to the patient and others. Please tell your doctor if such behaviors occur.
Falls
The use of benzodiazepines, including zolpidem, has been associated with an increased risk of falls. Falls may be caused by the side effects of benzodiazepines, such as coordination problems, muscle weakness, dizziness, drowsiness, and fatigue. The risk of falls is greater in older patients and if a higher dose than recommended is taken.
Psychomotor impairment the next day (see also "Driving and using machines")
The day after taking zolpidem, the risk of psychomotor impairment, including impaired driving ability, may be increased if:
Take the dose once and immediately before bedtime.
Do not take another dose during the same night.
Special patient groups
Zolpidem or other sedatives should be used with caution in patients:
Other medicines and Zolpidem Vir
Consult your doctor or pharmacist if you are taking, have recently taken, or might take any other
If you take zolpidem with the following medicines, the effects such as drowsiness or psychomotor impairment the next day, including impaired driving ability, may be increased.
If you take zolpidem with antidepressants, including bupropion, desipramine, fluoxetine, sertraline, and venlafaxine, you may see things that are not real (hallucinations).
It is not recommended to take zolpidem with fluvoxamine or ciprofloxacin.
Medicines that significantly increase the activity of certain liver enzymes may reduce the effect of zolpidem, e.g., rifampicin (an antibioticused to treat, for example, tuberculosis).
Grapefruit juice may increase the effect of zolpidem. Therefore, you should not drink grapefruit juice during treatment with zolpidem. During treatment, avoid alcoholic beverages, as the effect of alcohol may potentiate sedation.
Opioids
Concomitant use of zolpidem and opioids (strong painkillers, substitution therapy medicines, and some cough medicines) increases the risk of drowsiness, respiratory difficulties (respiratory depression), coma, and can be potentially fatal. Due to this, concomitant use should only be considered when other treatment options are not possible.
However, if your doctor prescribes zolpidem along with opioids, the dose and duration of concomitant treatment should be limited by your doctor.
Please consult your doctor about all opioid medicines you are taking and strictly follow your doctor's dosage recommendations. It may be useful to inform friends or family members to be aware of the signs and symptoms mentioned above. Contact your doctor when you experience such symptoms.
Analgesics
In the case of concomitant use with narcotic analgesics, you may experience an increased sense of well-being, which could lead to increased mental dependence (psychological).
St. John's Wort and rifampicin
Concomitant administration with St. John's Wort or rifampicin (a medicine used to combat tuberculosis) may reduce the effectiveness of zolpidem.
Ketoconazole
Concomitant use with ketoconazole, an antifungal medicine, may intensify the effect of zolpidem.
Pregnancy
The use of zolpidem during pregnancy is not recommended.
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, consult your doctor or pharmacist before using this medicine.
If zolpidem is used during pregnancy, there is a risk that the baby may be affected. Some studies have shown an increased risk of cleft lip and palate (sometimes called "harelip" in newborns.
Reduced fetal movement and fetal heart rate variability may occur after taking zolpidem during the second and/or third trimester of pregnancy.
If you take zolpidem in the last months of pregnancy or during childbirth, your baby may experience abnormal low body temperature (hypothermia), low muscle tone (hypotonia), and moderate respiratory failure (respiratory depression).
If you take this medicine regularly at the end of pregnancy, your baby may develop symptoms of physical dependence and may be at risk of developing withdrawal symptoms such as agitation or tremors. In this case, the newborn should be closely monitored during the postnatal period.
Breastfeeding
You should not take zolpidem during breastfeeding because zolpidem passes into breast milk.
Zolpidem Vir has a significant effect on the ability to drive and use machines, such as "driving in a somnolent state". On days when you take Zolpidem Vir (as with other hypnotics), you should consider the following:
To reduce these effects, a minimum margin of 8 hours is recommended between the administration of zolpidem and driving, using machinery, or any work at heights.
Do not consume alcohol or any other psychoactive substance while taking Zolpidem Vir, as this may increase the aforementioned effects.

Swallow the tablet with sufficient liquid (e.g., 1 glass of water) right before bedtime. It is recommended to sleep for 7 to 8 hours after taking the tablet.
Duration of treatment
The duration of treatment should be as short as possible and should not exceed four weeks, including gradual withdrawal of the medication, as the risk of abuse and dependence increases with the duration of treatment.

In cases of overdose, symptoms can range from extreme drowsiness to mild coma.
In case of overdose or accidental ingestion, contact your doctor, pharmacist immediately, and call the Toxicology Information Service. Phone: 91 562 04 20, indicating the medication and the amount ingested.
If you (or someone else) ingest many tablets at the same time, or if you think a child has ingested some of the tablets, contact your doctor or the emergency department of the nearest hospital immediately. Take the package and the remaining tablets with you. Do not go alone to seek medical help. If you have taken an overdose, drowsiness can increase rapidly, and high doses can lead to coma or even death. If zolpidem is taken with other central nervous system medications (including alcohol), it can have a severe outcome that can also be fatal. In moderate cases, symptoms include: drowsiness, mental confusion, and feeling of fatigue, exhaustion (lethargy). In more severe cases, symptoms can include lack of coordination (ataxia), decreased muscle tone (hypotonia), low blood pressure (hypotension), respiratory depression, altered consciousness up to coma, and more severe symptoms, including a fatal outcome.
It may happen that you forget to take zolpidem. In this case, it is not necessary to take the forgotten dose. Instead, take the dose prescribed by your doctor at the usual time. Do not take a double dose to make up for the forgotten doses.
If you interrupt treatment with Zolpidem Vir
Do not stop taking zolpidem suddenly, as you may experience withdrawal symptoms such as headache, muscle pain, fear, and severe tension, restlessness, confusion, and irritability. Consult your doctor to discontinue treatment by gradually reducing the dose.
If you have any other questions about the use of this medication, ask your doctor or pharmacist.
