1. What Nitrazepam Tablets are and what they are used for
Nitrazepam is a sedative and belongs to a group of drugs called benzodiazepines which work by having a calming effect.
This medicine is used for the short-term treatment of insomnia (difficulty sleeping) when it is severe, affecting your daily life or causing you extreme distress. Your doctor will work out the reason for your insomnia before prescribing this medicine.
This medicine should be used for as short a time as possible and should not be used for more than 4 weeks. If used for too long without a break, there is a risk of becoming dependent or of having problems when you stop taking it.
The risk of dependence (a need to keep taking the medicine) increases with dose and length of treatment period and is greater if you have ever had a history of alcohol or drug abuse, or in patients with personality disorders. Your doctor will monitor you whilst you are taking this medicine and will withdraw your treatment gradually.
2. Before you take Nitrazepam Tablets

* are allergic to nitrazepam, other benzodiazepines e.g. diazepam, or to any of the other ingredients in the tablets (see section 6)

Check with your doctor before taking these tablets if you:
* have glaucoma (increased pressure in the eye)
* have a history of alcohol or drug abuse
■ are elderly or have a personality disorder as you are more likely to experience side effects (see section 4 Possible side effects)
* have recently suffered from a bereavement as this medicine may prevent you from accepting the fact.
Taking other medicines:
Check with your doctor or pharmacist before taking these tablets if you are taking any other medicines, including any that you can buy without a prescription. This is particularly important if you are taking:
* other sedative/tranquilliser medicines for helping you to sleep, or medicines for treating depression, mental illness or anxiety
■ strong pain killers e.g. codeine
■ anaesthetics - before you have any surgical or dental operations tell your doctor or dentist you are taking nitrazepam

* anti-histamines (used to treat hay fever or other allergies) which cause drowsiness
* medicines used to treat epilepsy e.g. phenobarbital or phenytoin
* cisapride used to treat acid reflux (GORD)
* lofexidine used to relieve drug addiction withdrawal symptoms
- nabilone used to reduce nausea and vomiting caused by many anticancer medicines
* disulfiram used to treat alcoholism
■ baclofen or tizanidine used to treat muscle spasms caused by multiple sclerosis or spinal cord injury or disease
- medicines that affect liver enzymes e.g. cimetidine (used to treat stomach ulcers) and rifampicin (used to treat bacterial infections)

Other special warnings:
If you are elderly you should take extra care if you get up during the night because Nitrazepam Tablets relax the muscles. This means there is a risk you may fall and consequently hip fractures may occur.
Alcohol:
Avoid drinking alcohol while taking this medicine as it will increase the effects of this medicine.
Pregnancy and breast feeding:
Do not take Nitrazepam Tablets if you are pregnant, might become pregnant or breast feeding. If you and your doctor decide that you should take this medicine towards the end of your pregnancy (or during labour), this may harm your baby. The baby may have a low temperature, be listless, have breathing problems or difficulty in feeding. Also if you take this medicine regularly during your pregnancy, your baby may get withdrawal symptoms.
Driving and using machines:
The medicine can affect your ability to drive or operate machinery as it may make you sleepy or dizzy or may cause memory loss, lack of concentration, blurred vision and poor muscle function. If affected, do not drive or operate machinery, or take part in any activities that would put yourself or others at risk. If you do not get enough sleep at night the likelihood of reduced alertness may be increased.
Taking nitrazepam at the same time as some other medicines such as CNS depressants (sometimes referred to as tranquillisers and sedatives) may increase these effects.
* Do not drive while taking this medicine until you know how it affects you.
■ It is an offence to drive if this medicine affects your ability to drive.
- However, you would not be committing an offence if:
- The medicine has been prescribed to treat a medical or dental problem and
- You have taken it according to the instruction given by the prescriber or in the information provided with the medicine and
- It was not affecting your ability to drive safely.
Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

Stopping Nitrazepam and withdrawal effects:
Insomnia may re-occur when you stop taking this medicine and is greater if you suddenly stop taking the tablets.

Withdrawal symptoms will be worse in patients who have a history of alcohol or drug addiction, but can occur in patients receiving normal doses for a short period of time.
