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.

If you forget to take it

If you forget to take Mogadon before you go to bed and you wake up late in the night or early morning, do not take any Mogadon as you may have trouble waking in the morning. If you have any questions about this, ask your doctor or pharmacist.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Mogadon. Do this even if there are no signs of discomfort or poisoning. Report any other medicine or alcohol, which has been taken. You may need urgent medical attention. Keep telephone numbers for these places handy.

If you take too much Mogadon the mild symptoms are drowsiness, mental confusion and lethargy. In more serious cases, symptoms are inability to move, loss of muscle tone, hypotension, breathing difficulties, coma and very rarely death.

Things you must not do

Do not drive or operate machinery until you know how Mogadon affects you.

Mogadon causes drowsiness and affects alertness in most people.

Things to be careful of

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

Your doctor may suggest that you avoid alcohol or reduce the amount of alcohol you drink while you are taking Mogadon.

You should not take Mogadon if you experience complex sleep behaviours such as sleep walking, sleep driving or any other bizarre sleep-related behaviours.
