zolpidem tartrate
What Zolpidem Sandoz is and what it is used for
Zolpidem Sandoz is used for the short-term treatment of insomnia in adults. Do not use it for a long time. The treatment time should be as short as possible because the risk of addiction increases with the length of the treatment.
The medicine is only used if the insomnia is severe, disabling, or causes the patient great discomfort.
Zolpidem contained in Zolpidem Sandoz may also be approved to treat other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.
What you need to know before taking Zolpidem Sandoz
Do not take Zolpidem Sandoz
- if you are allergic to zolpidem or any of the other ingredients of this medicine (listed in section 6).
- if you have a certain type of muscle weakness ( myasthenia gravis )
- if you have temporary pauses in breathing when you sleep ( sleep apnea )
- if you have acute and/or severe breathing problems ( respiratory insufficiency )
- if you have severely impaired liver function ( liver insufficiency )
- if you have ever sleepwalked or experienced other unusual behavior during sleep after taking Zolpidem Sandoz or other medicines containing zolpidem. It can e.g. be driving, eating, making a phone call, or having sex without being fully awake.
Warnings and precautions
Talk to your doctor or pharmacist before taking Zolpidem Sandoz.
Generally
Before starting treatment with Zolpidem Sandoz,
- the cause of the sleep problems is determined as well as the possibility of treating these without drugs
- underlying diseases are treated.
If the sleep problems persist after 7-14 days of treatment with Zolpidem Sandoz, the doctor will carry out more examinations to investigate the causes.
Tolerance
Repeated use of sleeping pills for a few weeks can cause the effect to decrease (tolerance).
Dependent
Use of Zolpidem Sandoz can lead to the development of addiction and/or physical and psychological dependence. The risk of dependence increases with the dose and duration of treatment and is greater if zolpidem is used for more than 4 weeks. The risk of abuse and dependence is greater in patients who have previously had mental illnesses and/or abused alcohol, drugs, or medicines. Tell the doctor if you have or have had a mental illness, if you abuse or have abused alcohol, drugs, or medicines, or if you are or have been dependent on these substances.
Withdrawal symptoms
If a physical dependence has developed, sudden discontinuation of treatment leads to withdrawal symptoms such as headache, muscle pain, anxiety and tension, restlessness, confusion, and irritability. In severe cases, feelings of unreality, personality changes, hearing changes (increased sound perception, hyperacusis), numbness and tingling in the arms and legs, hypersensitivity to light, sound, and touch, hallucinations, and epileptic seizures may occur. The treatment should therefore be ended slowly by gradually reducing the dose. Zolpidem can cause withdrawal symptoms even between doses.
When treatment ends, temporary withdrawal symptoms may occur and the symptoms that led to treatment with Zolpidem Sandoz may return in an aggravated form. It can be accompanied by mood swings, anxiety, and restlessness. Since the risk of withdrawal or withdrawal symptoms is higher if treatment is stopped suddenly, treatment should be stopped slowly by gradually reducing the dose.
When Zolpidem Sandoz is taken as recommended for the dose and duration of treatment, and warnings and precautions are followed, the risk of withdrawal or withdrawal symptoms when treatment ends is minimal.
Zolpidem Sandoz is not recommended as a basic treatment for certain mental illnesses ( psychosis ).
Depression
As with other hypnotics or sedatives, Zolpidem Sandoz should be used with caution in patients with symptoms of depression or anxiety accompanied by depression. In some circumstances, the symptoms of depression may worsen if the underlying illness is not treated appropriately (with antidepressants). This may increase the risk of suicide in these patients. A previously hidden depression may become apparent when taking Zolpidem Sandoz. Some studies have shown an increased number of suicides or suicide attempts in patients taking certain sleeping pills or tranquilizers, including Zolpidem Sandoz.
However, it has not been established whether this is due to the drug treatment or whether it may have other causes.
If you have suicidal thoughts (thinking about harming yourself or committing suicide) or suicidal behavior, contact your doctor as soon as possible.
Memory lapses ( amnesia )
Sleeping pills can cause short and temporary memory lapses (anterograde amnesia ). This means that after taking this medicine (usually a few hours later) you may do things that you then do not remember. It can also be about inappropriate behavior. How big the risk of memory gaps is depends on the dose. To minimize the risk, make sure you get 8 hours of undisturbed sleep.
Psychic and paradoxical reactions
Zolpidem Sandoz can cause psychological and so-called paradoxical reactions, such as restlessness, worsening insomnia, agitation, irritability, aggressiveness, delusions, outbursts of anger, nightmares, hallucinations (seeing, hearing, or feeling things that are not there), abnormal behavior, and other behavioral disorders, especially in elderly patients (see section 4). If this occurs, treatment with Zolpidem Sandoz should be discontinued (see section 4).
Bedtime
Sleepwalking and similar behaviors have also been reported in patients taking zolpidem who were not fully awake. This includes driving, cooking and eating, making phone calls, or having sex without remembering it when you wake up. If you notice any of the above behaviors, stop treatment with Zolpidem Sandoz immediately and consult a doctor, as these sleep behaviors can pose serious risks to you and others. Drinking alcohol or taking other drugs that make you sleepy along with zolpidem can increase the risk of these sleep behaviors occurring.
Coordination problems
Coordination problems the following day (see also “Driving ability and use of machines”
Like other hypnotics and sedatives, Zolpidem Sandoz can have a depressant effect on the central nervous system.
The day after taking Zolpidem Sandoz, the risk of coordination problems, including impaired driving ability, may be greater if:
- you take this medicine less than 8 hours before performing activities that require alertness
- you are taking a higher dose than recommended
- you take zolpidem at the same time as you take other sedatives that affect the function of the central nervous system, other medicines that increase zolpidem in the blood, drink alcohol, or use drugs or medicines.
Take the full dose just before going to bed.
Do not take any additional dose on the same night.
The use of zolpidem has been associated with an increased risk of falls. Falls can be caused by side effects such as coordination problems, muscle weakness, dizziness, drowsiness, and fatigue. The risk of falling is higher in elderly patients if a higher-than-recommended dose is used.
Impaired respiratory and liver function
Patients with chronic impaired respiratory function or impaired liver function should be treated with caution and the doctor may prescribe a lower dose of Zolpidem Sandoz (see also section 3). Due to the risk of brain damage, patients with severely impaired liver function should not be treated with Zolpidem Sandoz.
Heart problems
Patients with a specific congenital disease of the electrical conduction of the heart (so-called ” long QT syndrome “) should be treated with caution. The doctor will carefully weigh the benefits against the risks before prescribing treatment with Zolpidem Sandoz.
Elderly patients and patients with reduced general condition
These patients should receive a lower dose (see section 3). Caution is required when prescribing to elderly patients due to the risk of falls, especially when getting up at night.
Children and young people
Zolpidem Sandoz is not recommended for children and adolescents under 18 years of age as there are insufficient clinical data for this age group.
Special patient groups
Other medicines and Zolpidem Sandoz
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
The following medicines can affect the effect of Zolpidem Sandoz or can be affected by Zolpidem Sandoz:
The risk of drowsiness and problems with coordination the following day, including impaired ability to drive, maybe higher the day after taking zolpidem if it is taken at the same time as the following medicines:
- medicines for certain mental problems (antipsychotics)
- medicines for sleep problems ( hypnotics )
- drugs that suppress or reduce anxiety
- medication for depression
- medicines for moderate or severe pain (narcotic analgesics )
- drugs against epilepsy
- drugs used in anesthesia
- medicines for hay fever, rashes, or other allergies that can make you sleepy (sedative antihistamines).
Simultaneous use of Zolpidem Sandoz and opioid medicines (strong painkillers, medicines for the treatment of patients who have become addicted to opioids, as well as certain cough medicines) increases the risk of drowsiness, breathing difficulties ( respiratory depression ), coma and can be life-threatening. Because of this, concomitant use should only be considered by the physician when other treatment options are not possible.
If your doctor prescribes Zolpidem Sandoz together with opioid medicines, the doctor must limit the dose and duration of treatment for simultaneous treatment.
Tell your doctor if you are taking any opioid medication and follow your doctor’s dosage recommendations carefully. It may be good to inform friends or relatives to be aware of the signs and symptoms described above. Contact a doctor if you experience any of these symptoms.
Combination with opiate-type painkillers (narcotic analgesics ) can also lead to an addiction developing more quickly.
If you take zolpidem at the same time as antidepressants such as bupropion, desipramine, fluoxetine, sertraline, or venlafaxine, you may see things that are not real (hallucinations).
You are advised not to take zolpidem together with fluvoxamine or ciprofloxacin.
With the simultaneous use of muscle relaxants, the effect of muscle relaxants can be increased – especially in elderly patients and at higher doses (risk of falling accidents!).
Medicines that increase the activity of certain liver enzymes (especially the P450 isoenzyme et CP3A4) may reduce the effect of Zolpidem Sandoz (eg rifampicin, carbamazepine, phenytoin, and St. John’s wort ). Concomitant use of zolpidem and St. John’s wort is not recommended.
Certain medicines against fungal infections (azoles eg ketoconazole ) and certain antibiotics ( macrolide antibiotics ) can, on the other hand, increase the effect of Zolpidem Sandoz because they weaken the effect of these liver enzymes.
Zolpidem Sandoz with food, drink, and alcohol
You should not drink alcohol during treatment as this alters and enhances the effect of zolpidem unpredictably. The ability to carry out tasks that require increased concentration is also impaired by this combination. Grapefruit juice may increase the effect of Zolpidem Sandoz.
Pregnancy, breastfeeding, and fertility
Pregnancy
Use of Zolpidem Sandoz is not recommended during pregnancy. If you are pregnant, think you may be pregnant, or are planning to have a baby, consult a doctor.
There is a risk that the baby will be affected if this medicine is used during pregnancy. Some studies have shown that there may be an increased risk of cleft lip and palate (“cleft palate”) in newborns.
Reduced fetal movements and effects on the fetal heart rate may occur after taking Zolpidem Sandoz during the last six months of pregnancy.
If Zolpidem Sandoz is taken at the end of pregnancy or during childbirth, the child may have symptoms such as muscle weakness, lower body temperature, difficulty eating, and breathing problems ( respiratory depression ).
With regular use late in pregnancy, the child may develop a physical dependence and run the risk of developing withdrawal symptoms such as restlessness and tremors. In this case, the newborn baby must be followed up closely by a doctor after birth.
Breast-feeding
As zolpidem is excreted in breast milk in small amounts, Zolpidem Sandoz should not be taken during breastfeeding.
Fertility
There are no data on the effects on fertility.
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Driving ability and use of machinery
Zolpidem Sandoz has a major influence on the ability to drive and use machines, through for example sleepwalking and driving when you are not fully awake (“sleep-driving”). The day after taking Zolpidem Sandoz (as well as other sleeping pills), you should be aware that:
- you may feel drowsy, sleepy, dizzy, or confused
- it may take you longer to make a quick decision
- you may see blurry or double
- you can pay less attention.
A period of at least 8 hours is recommended between taking zolpidem and driving, using machinery, or working at high altitudes to minimize the effects mentioned above.
Do not drink alcohol or take other psychoactive substances while taking Zolpidem Sandoz as this may increase the effects mentioned above.
You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. A description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with a doctor or pharmacist if you are unsure.
Zolpidem Sandoz contains lactose and sodium
If you have an intolerance to some sugars, you should contact your doctor before taking this medicine.
This medicine contains less than 1 mmol (23 mg) of sodium per tablet, i.e. is almost “sodium-free”.
How to take Zolpidem Sandoz
Always take this medicine as directed by your doctor. Ask your doctor or pharmacist if you are unsure.
Recommended dose
Adults
The recommended dose of Zolpidem Sandoz is 10 mg per 24 hours. Some patients may be prescribed a lower dose. Zolpidem Sandoz should be taken:
- as a single dose
- in connection with bedtime.
Make sure that a period of at least 8 hours has passed after taking this medicine before doing activities that require you to be awake/alert.
Never take more than 10 mg per 24 hours.
Elderly patients and patients with reduced general condition
The recommended dose is 5 mg for elderly patients and patients with impaired general conditions as they may be particularly sensitive to Zolpidem Sandoz. This dose should only be increased to 10 mg if the effect is insufficient and the drug is well tolerated.
Breathing problems or impaired liver function
For patients with breathing problems or impaired liver function, the dose is 5 mg of Zolpidem Sandoz.
Children and young people
Zolpidem Sandoz is not recommended for children and adolescents under 18 years of age as there are insufficient clinical data to support use in this age group.
How to take the tablet
Zolpidem Sandoz should be taken with some liquid (water) immediately before bedtime or in bed.
How long should you take Zolpidem Sandoz?
The treatment period should be as short as possible, generally only a few days up to 2 weeks, and should not exceed 4 weeks, including the step-by-step tapering period.
In some cases, longer treatment may be necessary. However, the treatment should not be extended without a renewed medical assessment of your condition.
Children and young people
If you have taken too much Zolpidem Sandoz
If you have taken too much, you must contact a doctor immediately.
Signs of a (small) overdose can be drowsiness, dizziness, blurred vision, slurred speech, lowered blood pressure, unsteady gait and unsteady movements, muscle weakness, confusion, and hallucinations. In more serious overdoses, symptoms can range from deep sleep to unconsciousness, agitation, breathing problems, and circulatory collapse. Cases of zolpidem overdose (alone or in combination with other drugs that depress the central nervous system, including alcohol) have been reported with serious consequences (even life-threatening).
If you have ingested too much medicine or if, for example, a child has ingested the medicine by mistake, contact a doctor or hospital for an assessment of the risk and advice.
If you forget to take Zolpidem Sandoz
Do not take a double dose to make up for a missed dose. Continue as usual the next day with the dose of Zolpidem Sandoz prescribed by your doctor.
If you stop using Zolpidem Sandoz
If you want to stop the treatment, you should first discuss it with the doctor. Do not stop treatment on your initiative without receiving medical advice. As the risk of withdrawal symptoms is higher if the treatment is stopped suddenly, the doctor will advise you to stop by gradually reducing the dose, see section 2 “Warnings and precautions”, paragraph “Withdrawal symptoms”.
Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Stop taking zolpidem and contact a doctor or go to the hospital immediately if you develop an allergic reaction ( angioedema ). Signs of such a reaction may include raised and itchy rashes ( hives ), and swelling of the hands, feet, ankles, face, lips, or throat which may lead to difficulty swallowing or breathing.
Side effects can be dose-dependent, especially side effects that affect the central nervous system. To reduce such side effects, it is recommended that zolpidem be taken immediately before bedtime or in bed. Side effects are more common in older people.
