6. Further information


Mogadon belongs to a group of medicines known as benzodiazepines, which are tranquillisers (medicines that have a calming effect).

Mogadon shortens the time taken to fall asleep and lengthens the duration of sleep.

Mogadon Tablets are used for the short term treatment of sleeplessness (also known as insomnia) when it is severe.

Mogadon Tablets help you to sleep but do not cure the underlying cause of your insomnia, which you should discuss with your doctor.


Do not take Mogadon Tablets if you:

  • are allergic (hypersensitive) to nitrazepam or any of the other ingredients of Mogadon Tablets (these are listed in section 6, ˝Further Information˝).
  • are allergic (hypersensitive) 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.

Mogadon Tablets are not for use in anyone under 18 years of age.

Take special care with Mogadon Tablets

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 Mogadon.
  • are pregnant or breast-feeding.

Because Mogadon 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.

Taking other medicines

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).

Taking Mogadon Tablets with food and drink

Do not drink alcohol for as long as you are taking Mogadon Tablets. Alcohol will increase the effects of the tablets and this can be dangerous.

Pregnancy and breast-feeding

Tell your doctor before taking Mogadon 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.

Tell your doctor before taking Mogadon Tablets if you are breast-feeding. Avoid taking Mogadon Tablets if you are breast-feeding as Mogadon passes into breast-milk.

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 and 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.

Driving and using machines

Mogadon 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 effects.

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:

The medicine has been prescribed to treat a medical or dental problem and

  • You have taken it according to the instructions 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.

Important information about some of the ingredients of Mogadon Tablets

Lactose: Mogadon tablets contain lactose. Therefore, if you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.


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 bodyweight.

Always take Mogadon exactly as your doctor has told you. Do not change the prescribed dose yourself. You should check with your doctor or pharmacist if you are not sure how to take this medicine. If you think that the effect of your medicine is too weak or too strong, talk to your doctor.

Mogadon 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.

Mogadon 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, Mogadon 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 Mogadon and reduce the risk of dependence.

Withdrawal symptoms may occur when you stop taking Mogadon Tablets (see section below When you stop taking Mogadon Tablets).

Do not stop taking Mogadon Tablets without speaking to your doctor.

If you take more Mogadon 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 forget to take Mogadon

Do not take a double dose to make up for a forgotten dose. Instead you should simply continue with the next dose when it is due.

When you stop taking Mogadon Tablets

Your doctor will advise you when to stop taking the tablets.

Do not stop taking Mogadon 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:

  • a recurrence of sleep problems
  • depression
  • nervousness
  • extreme anxiety
  • tension
  • restlessness
  • confusion

  • 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.
