1. What Stilnoct is and what it is used for
The name of your medicine is Stilnoct 5mg Film-Coated 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 714 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.


Before you take Stilnoct

Do not take this medicine and tell your doctor if:
 You are allergic (hypersensitive) to zolpidem tartrate or any of the other ingredients of
Stilnoct (listed in section 6 below)
Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling
of your lips, face, throat or tongue
 Your lungs do not work properly (respiratory failure)
 You have severe liver problems
 You have a problem where you stop breathing for short periods at night (sleep apnoea)

You have a problem that causes severe muscle weakness (myasthenia gravis)
You have been told by a doctor that you have a mental illness (psychosis)

Do not take this medicine if any of the above applies to you. If you are not sure, talk to your
doctor or pharmacist before taking Stilnoct.

 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

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.

Do not take another dose during the same night.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other
medicines. This includes medicines you buy without a prescription, including herbal
medicines. This is because Stilnoct can affect the way some other medicines work. Also some
medicines can affect the way Stilnoct works.
