1. What Nitrazepam Tablets are and what they are used for
Nitrazepam belongs to a group of medicines known as benzodiazepines, which are tranquillisers
(medicines that have a calming effect). Nitrazepam shortens the time taken to fall asleep and
lengthens the duration of sleep. Nitrazepam Tablets are used for the short term treatment of
sleeplessness (also known as insomnia) when it is severe. Nitrazepam Tablets help you to sleep
but do not cure the underlying cause of your insomnia, which you should discuss with your
2. What you need to know before you take Nitrazepam tablets
Do not take Nitrazepam Tablets if you:
- are allergic to nitrazepam or any of the other ingredients of Nitrazepam Tablets (listed in
section 6).
- are allergic to any medicine known as a benzodiazepine (e.g. flurazepam, diazepam,
chlordiazepoxide or temazepam).
- suffer from lung disease.
- suffer from difficulty breathing while awake or asleep.
- suffer from myasthenia gravis (a condition in which the muscles become weak and tire easily).

- are suffering from a psychiatric illness or a personality disorder (severe mental problems).
- have a severe liver condition.
Nitrazepam Tablets are not for use in anyone under 18 years of age.
Warnings and Precautions
Tell your doctor before you take these tablets if you:
- have a long-term lung, liver or kidney disease.
- suffer from depression or have recently suffered the death of a close friend or relative.
- are suffering or have suffered from a mental illness.
- have abused alcohol or drugs. You must not drink alcohol or use drugs while taking
- are pregnant or breast-feeding
Because Nitrazepam Tablets relax the muscles, elderly patients should take extra care when they
get up at night as there is a risk of falls and consequently of injuries including hip fractures.

Other medicines and Nitrazepam tablets
Tell your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription. This is extremely important, as using more
than one medicine at the same time can strengthen or weaken the effect of the medicines
involved. In particular, tell your doctor if you are taking any of the following medicines:
- Antidepressants, other tranquillisers or sleeping pills, or other such medicines that act on the
brain and nerves.- Medicines used to relieve pain or anaesthetics.
- Antihistamines (used for treating allergies) that cause drowsiness (e.g. chlorphenamine).
- Medicines for treating epilepsy (e.g. phenytoin and phenobarbital) - Medicines that affect the liver (e.g. the antibiotic rifampicin).

Nitrazepam Tablets with food, drink and alcohol
Do not drink alcohol while you are taking Nitrazepam tablets.
Alcohol will increase the effects of the tablets and this can be dangerous.
Pregnancy, Breast-feeding and Fertility
Tell your doctor before taking Nitrazepam Tablets if you are pregnant, think that you are
pregnant or intend to become pregnant during treatment. Your doctor will then decide whether
you should take this medicine.
If your doctor has decided that you should receive this medicine during late pregnancy or during
labour, your baby might have a low body temperature, floppiness, breathing and feeding

difficulties. Also, your unborn baby may be at risk of developing dependency to this medicine
and after birth may be at some risk of developing withdrawal symptoms.
Tell your doctor before taking Nitrazepam Tablets if you are breastfeeding. Avoid taking
Nitrazepam Tablets if you are breast-feeding as Nitrazepam passes into breast-milk.

Nitrazepam Tablets may cause side effects such as reduced alertness, confusion, tiredness,
dizziness, poor muscle co-ordination and double vision. This may affect your ability to drive and
operate machinery. Do not drive or operate machinery if you experience any of these side
The medicine can affect your ability to drive. Do not drive while taking this medicine until you
know how it affects you.
It may be an offence to drive if your ability to drive safely is affected. However, you would not
be committing an offence if:

3. How to take Nitrazepam Tablets
Your doctor will find the lowest dose to control your symptoms. The dose that your doctor
prescribes will depend on the nature of your illness, your reaction to the medicine, your age and
Always take Nitrazepam tablets exactly as your doctor has told you. Do not change the
prescribed dose yourself. You should not take Nitrazepam tablets for longer than 4 weeks.
Check with your doctor or pharmacist if you are not sure. If you think that the effect of your
medicine is too weak or too strong, talk to your doctor.

Nitrazepam is not for use in children.
The usual starting dose is 5 mg (one tablet). However, if you are elderly or suffer from a lung,
liver or kidney condition, or are generally unwell, your starting dose will not usually be more
than 2.5 mg (half a tablet).
You may not need to take this medicine every night.
Swallow the tablet(s) whole with water or another non-alcoholic drink.
Take the medicine just before going to bed. Make sure that you can sleep without interruptions
for 7 to 8 hours after taking the tablets.
Treatment will not normally be continued for more than four weeks
Nitrazepam Tablets may become less effective if you take them for more than four weeks. If you
think that your medicine is no longer working or your insomnia does not improve, you should
consult your doctor.
Also, you may become dependent on the tablets if you use them at high doses and for long
periods. Therefore, Nitrazepam Tablets are not suitable for long-term use and after a few weeks
it is worth trying to get by without these tablets. This will help to prevent you becoming used to
Nitrazepam and reduce the risk of dependence.
Withdrawal symptoms may occur when you stop taking Nitrazepam Tablets (see section below
when you stop taking Nitrazepam Tablets). Do not stop taking Nitrazepam Tablets without
speaking to your doctor.
If you take more Nitrazepam Tablets than you should
If you take too many tablets or someone else accidentally takes your medicine, contact your
doctor, pharmacist or nearest hospital straight away. If you (or someone else) swallow a lot of
tablets at the same time, or you think a child may have swallowed any, contact your nearest
hospital casualty department or tell your doctor immediately. Signs of an overdose include
slowing down of the nervous system ranging from tiredness to coma such as confusion,
drowsiness, lack of coordination, reduced muscle tension, low blood pressure, slow heart beat,
breathing difficulties, in rare cases overdose may lead to coma (unrousable unconsciousness) and
in very rare cases may lead to death.
If you forget to take Nitrazepam Tablets
Do not take a double dose to make up for a forgotten dose. If you forget to take a dose take it as
soon as you remember it and then take the next dose at the right time.

When you stop taking Nitrazepam Tablets
Your doctor will advise you when to stop taking the tablets. Do not stop taking Nitrazepam
tablets abruptly. You may experience withdrawal effects if your treatment is stopped suddenly.
This is less likely if your dose is gradually reduced towards the end of your treatment.
Withdrawal symptoms may include recurrence of sleep problems, depression, nervousness,
extreme anxiety, tension, restlessness, confusion, mood changes, irritability, sweating, diarrhoea,
headaches and muscle weakness.
In severe cases the following symptoms may occur:
- changes in behaviour
- numbness and tingling of the extremities
- fits
- over-sensitivity to light, noise and touch
- hallucinations
If you have taken benzodiazepines for a long time, the reduction in your dosage will be over a
longer period of time than would normally be required when you stop taking this medicine. You
may need additional help. Your doctor will be able to discuss this with you. If you have any
further questions on the use of this product, ask your doctor or pharmacist.
