Mogadon is used to treat sleeping problems, also called insomnia.

Mogadon can cross the placenta and cause side effects in your unborn baby. Withdrawal symptoms have also been reported in newborn babies.

Use in Children

Do not give this medicine to children unless advised by the child’s doctor.

The safety and effectiveness of this medicine in children have not been established.

Use in the Elderly

Elderly people may be more susceptible to the sedative effects of Mogadon and associated giddiness, unsteadiness, and confusion, which may increase the possibility of a fall.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with Mogadon and affect how it works including:

  • medicines to control fits
  • cimetidine, a medicine used to treat ulcers and reflux
  • disulfiram, a medicine used to deter the consumption of alcohol.

  • other sleeping tablets, sedatives, or tranquillisers
  • medicines for depression
  • medicines for allergies, e.g., antihistamines or cold tablets

  • muscle relaxants.

Taking Mogadon with these medicines may slow down your nervous system more than intended resulting in lethargy, breathing problems, dizziness, confusion, or problems with your vision.

Seek urgent medical attention if life-threatening symptoms such as breathing difficulties, inability to move or coma occur.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Mogadon.

5. What should I know while using Mogadon?

Things you should do

Use Mogadon exactly as your doctor has prescribed.

Tell your doctor if you feel Mogadon is not helping your condition.

Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed.

Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.

Call your doctor or mental health professional straight away if you:

  • Have any suicidal thoughts or other mood changes. All thoughts of suicide must be taken seriously.
  • If you become pregnant while you are taking Mogadon.

Tell your doctor if you notice any unusual changes in your sleep behaviour such as sleep walking, sleep driving or any other bizarre sleep-related behaviours.

You may need medical attention if you experience these behaviours.

Be careful when taking Mogadon if you are elderly, unwell, or taking other medicines.

Some people may experience side effects such as drowsiness, confusion, dizziness, and unsteadiness. These may increase the risk of a fall.

Remind any doctor, mental health professional, dentist, or pharmacist you visit that you are using Mogadon.

Things you should not do

Do not take Mogadon for a longer time than your doctor has prescribed.

Mogadon is usually taken for short periods only (for example 2 – 4 weeks). Continuous long-term use is not recommended unless advised by your doctor. The use of benzodiazepines may lead to dependence on the medicine.

Do not stop using this medicine suddenly or change your dose without first checking with your doctor.

Your doctor will slowly reduce your dose of Mogadon before you can stop taking it completely.

  • anxiety or panic attacks
  • feeling dissatisfied with life
  • feeling ‘outside of your body’ or a sense of unreality
  • delusional beliefs
  • palpitations
  • involuntary movements

Mogadon causes drowsiness and affects alertness in most people.

Make sure you know how you react to Mogadon before you drive a car, operate machinery, or do anything else that could be dangerous if you are drowsy, dizzy, or not alert.

Even if you take Mogadon at night, you may still be drowsy or dizzy the next day.

Drinking alcohol

Tell your doctor if you drink alcohol.

Combining Mogadon and alcohol can make you more sleepy, dizzy, lightheaded or increase the risk of sleep disorders.
