1. What DAGAN is and what it is used for

Zolpidem tartrate is the active substance in DAGAN. It belongs to a group of medicines called hypnotics. It acts on the brain to help you sleep.

DAGAN is used to treat short-term sleep disorders in adults that are causing severe anxiety or affecting your daily life. These sleep disorders in adults include, among others:

• Difficulty falling asleep
• Waking up during the night
• Waking up too early

Your doctor will, whenever possible, identify your sleep problem and the factors causing it before prescribing this medicine. If your sleep problems do not resolve after 7 to 14 days of treatment, this may indicate an underlying disorder, and your doctor will evaluate you periodically.

DAGAN is not intended for daily use over prolonged periods of time (treatment should be as short as possible and not exceed 4 weeks). If you are unsure, consult your doctor.

2. What you need to know before taking DAGAN

Do not take DAGAN:

• if you are allergic to zolpidem tartrate or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include, among others: skin rash, difficulty swallowing or breathing, swelling of the lips, face, throat, or tongue.
• if your lungs do not function properly (respiratory failure).
• if you have severe liver problems.
• if you have a condition in which you stop breathing for short periods during sleep (sleep apnea).
• if you have a disorder causing severe muscle weakness (myasthenia gravis).
• if your doctor has informed you that you have a mental illness (psychosis).
• if you are under 18 years of age.

Do not take this medicine if any of the above apply to you. If you are unsure, consult your doctor or pharmacist before taking zolpidem.

Warnings and precautions

Consult your doctor or pharmacist before taking DAGAN if:

• You have a history of alcohol or drug abuse.
• You have liver problems.
• You suffer from depression or have had other mental illnesses in the past.
• You have recently taken zolpidem or similar medicines for more than four weeks.
• You have kidney problems.
• You have respiratory problems.
• You are elderly or frail.

Zolpidem may cause drowsiness and reduce your level of alertness. This could lead to falls and sometimes serious injuries.

If you are unsure whether the above applies to you, consult your doctor or pharmacist before taking zolpidem.

Duration of treatment

• Once you start taking DAGAN, you should know that it is only for a limited period.
• You should take zolpidem for a short period only, not exceeding 4 weeks.
• You must always attend follow-up appointments with your doctor as scheduled to reassess your condition.

Next-day psychomotor impairment (see also Driving and use of machines)

The risk of next-day psychomotor impairment, including impaired ability to drive, increases the following day after taking zolpidem if:

• You take this medicine less than 8 hours before performing activities requiring alertness.
• You take a higher dose than recommended.
• You take zolpidem together with another central nervous system depressant or another medicine that increases zolpidem levels in your blood, combined with alcohol or illegal substances.

Take a single dose immediately before going to bed at night. Do not take another dose during the same night.

Other medicines and DAGAN

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines. This is because zolpidem may affect how other medicines work. Likewise, some medicines may affect how zolpidem works.

Zolpidem may enhance the effect of muscle-relaxing medicines.

Rifampicin, a medicine used to treat tuberculosis, may reduce the effect of zolpidem.

Inform your doctor if you are taking any of the following medicines:

DAGAN may increase the effect of the following medicines:

If you take DAGAN with the following medicines, it may increase drowsiness and next-day psychomotor impairment, including impaired ability to drive:

• Medicines for certain mental disorders (antipsychotics)
• Medicines for sleep problems (hypnotics)
• Medicines to relieve or reduce anxiety
• Medicines for depression
• Medicines for moderate to severe pain (narcotic analgesics)
• Medicines for epilepsy
• Medicines used for anesthesia
• Medicines for seasonal allergic rhinitis, skin rashes, or other allergies that may cause drowsiness (sedating antihistamines)

If you take zolpidem with antidepressants, including bupropion, desipramine, fluoxetine, sertraline, and venlafaxine, you may see things that are not real (hallucinations).

If you take zolpidem with narcotic analgesics, you may feel euphoric and your dependence may increase.

Concomitant use of zolpidem with fluvoxamine is not recommended.

The following medicines increase the likelihood of side effects when taken with DAGAN. To reduce this risk, your doctor may decide to lower your dose of zolpidem:

• Some antibiotics such as ciprofloxacin (use not recommended)
• Some medicines used to treat fungal infections, such as ketoconazole or itraconazole

Taking DAGAN with food and drink

• Do not drink alcohol while taking zolpidem. Alcohol may enhance the effects of zolpidem and cause you to sleep so deeply that you may not breathe properly or have difficulty waking up.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine. Taking DAGAN during pregnancy may be harmful to your baby.

Zolpidem should not be administered during pregnancy, especially during the first three months. If, for urgent medical reasons, you take zolpidem during the last months of pregnancy or during childbirth, your baby may experience low body temperature, muscle spasms, breathing difficulties, and withdrawal symptoms after birth due to physical dependence.

You should not breastfeed while taking zolpidem, as this medicine is excreted in small amounts in breast milk.

Seek advice from your doctor or pharmacist before taking any medicine if you are pregnant or breastfeeding.

Driving and use of machines

DAGAN has a significant effect on the ability to drive and use machines, such as "driving while drowsy." The day after taking zolpidem (as with other hypnotics), you should be aware that you may experience the following:

• You may feel drowsy, sleepy, dizzy, or confused
• It may take you longer than usual to make decisions
• You may experience blurred or double vision
• Your level of alertness may be reduced

To reduce the aforementioned effects, a minimum interval of 8 hours between taking zolpidem and driving, operating machinery, or performing work at heights is recommended.

Do not consume alcohol or any other psychoactive substance while taking zolpidem, as this may increase the effects mentioned above.

DAGAN contains:

• Lactose. If your doctor has diagnosed you with an intolerance to certain sugars, consult with him before taking this medicine.
• Aspartame (E951): This medicine contains 5 mg of aspartame per tablet. Aspartame contains a source of phenylalanine, which may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine accumulates because the body cannot eliminate it properly.
• Ammonium sulfite caramel (E150d): This medicine may cause severe allergic reactions and bronchospasm (sudden sensation of suffocation) because it contains sulfites.

3. How to take DAGAN

Follow exactly the administration instructions for DAGAN given by your doctor. If in doubt, consult your doctor or pharmacist again.

Taking this medicine

• Take this medicine by mouth.

• Place the tablet on the tongue and allow it to dissolve until it disintegrates without chewing. Swallow the resulting suspension with saliva. You may then drink water, but it is not required.

• The recommended dose is 10 mg of DAGAN every 24 hours.

• A lower dose may be prescribed for some patients.

• Zolpidem should be taken as a single dose immediately before going to bed at night.

• Ensure a minimum interval of 8 hours between taking the medicine and performing activities requiring alertness.

• Do not take more than 10 mg every 24 hours.

• The usual duration of treatment is 2 days to 4 weeks. The maximum treatment period, including the gradual dose reduction process, is four weeks.

Adults

The recommended dose is two 5 mg tablets or one 10 mg tablet (10 mg) taken just before bedtime. The maximum dose of 10 mg must not be exceeded.

Elderly patients (over 65 years of age) or debilitated patients

The recommended dose is one 5 mg tablet taken just before bedtime. This recommended dose must not be exceeded.

Patients with liver problems

The initial dose is one 5 mg tablet taken just before bedtime. Your doctor will decide whether the dose should be increased to two 5 mg tablets or to one 10 mg tablet, if it is considered safe to do so.

Do not take zolpidem if you have severe liver disorders.

Use in children and adolescents

Children under 18 years of age must not use DAGAN.

If you take more DAGAN than you should

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately or call the Toxicology Information Service at telephone: 91 5620420, stating the medicine and the amount ingested.

Bring the medicine packaging with you so the doctor knows what you have taken. Taking too much zolpidem is very dangerous. The following effects may occur:

• drowsiness, mental confusion, hypotension, breathing difficulty, deep sleep, and possible progression to a fatal coma.

If you forget to take DAGAN

DAGAN should only be taken at bedtime. If you forget to take the dose at bedtime, do not take it at any other time, as you may feel drowsy, dizzy, and confused during the day.

Do not take a double dose to make up for a missed dose.

If you forgot to take the dose immediately before going to bed but remember during the night, simply take the missed dose if you can still sleep for 7 or 8 hours uninterrupted.

If you stop taking DAGAN

Continue taking DAGAN until your doctor tells you to stop. Do not stop treatment with zolpidem suddenly, but inform your doctor if you wish to discontinue. Your doctor will need to gradually reduce your dose and taper off the tablets over a period of time.

If you stop taking zolpidem suddenly, your sleep problems may return and you may experience what are known as "withdrawal symptoms." If this happens, you may notice the following effects:

Go to the doctor immediately if any of the following occur:

• Feeling anxious and tense, restless, irritable, or confused
• Headache
• Nightmares, seeing or hearing things that are not real (hallucinations)
• Increased sensitivity to light, noise, and touch
• Disturbance in perception of reality
• Feeling detached from your body or as if you are a puppet
• Numbness and tingling in hands and feet
• Muscle pain
• Worsening of sleep disorders

In rare cases, seizures (convulsions) may also occur.
