1. What Stilnoct is and what it is
used for
The name of your medicine is Stilnoct 10mg FilmCoated Tablets (called Stilnoct in this leaflet).
Stilnoct contains a medicine called zolpidem
tartrate. This belongs to a group of medicines
called hypnotics. It works by acting on your brain
to help you sleep.
Stilnoct is used for temporary sleep problems in
adults that are causing you severe distress or that
are affecting your everyday life. This includes
sleep problems in adults such as:
• Difficulty falling asleep
• Waking in the middle of the night
• Waking too early
Your doctor will identify your sleep problem
wherever possible and the underlying factors
before prescribing this medicine for you. The
failure of your sleep problems to stop after a 7-14
day course of treatment may indicate you have an
underlying disorder, your doctor will assess you at
regular intervals.
Stilnoct is not meant to be used every day for long
periods of time. Ask your doctor for advice if you
are unsure.

Take special care with Stilnoct
Check with your doctor or pharmacist before
taking your medicine if:
▲ You have a history of alcohol or drug abuse
▲ You have liver problems
▲ You have depression or have had another
mental illness in the past
▲ You have recently taken Stilnoct or other
similar medicines for more than four weeks
▲ You are elderly
Stilnoct can cause drowsiness and decrease your
level of alertness. This could cause you to fall,
sometimes leading to severe injuries.
If you are not sure if any of the above applies to
you, talk to your doctor or pharmacist before
taking Stilnoct.
Next-day psychomotor impairment (see also
Driving and using machines)

breathe properly or have difficulty waking.

Talk to your doctor before taking this medicine if
you are pregnant, might become pregnant, or
think you may be pregnant. Taking Stilnoct
during pregnancy may harm your baby.

into mother’s milk.
