How much to take
- The usual adult dose of SOMIDEM is one tablet (10 mg).
- If you are over 65 years of age the dose is half a SOMIDEM tablet (5 mg).
- If you have any liver problems, the usual recommended dose is half a STILNOX tablet (5 mg). Do not take STILNOX if you have severe liver problems.

- If you take the wrong dose, SOMIDEM may not work as well.
- If you take too much your consciousness may be impaired (see ‘If you take too much SOMIDEM’ below).
- Ask your doctor if you are unsure of the correct dose for you. They will tell you exactly how much to take.
When to take SOMIDEM
- Take SOMIDEM immediately before you go to bed or while you are in bed.
- SOMIDEM should only be taken when you are able to get a full night’s sleep (7 to 8 hours) before you need to be active again. It should be taken in one dose and not be re-administered during the same night.
How long to take it
- Usually, SOMIDEM or any other medicines to treat sleeping disorders should only be used for short periods (e.g. 2 to 4 weeks). Continuous long term use is not recommended unless advised by your doctor.
Ask your doctor or pharmacist if you are not sure how long to take the medicine for.
How to take SOMIDEM
- Swallow the tablet whole with a full glass of water, unless your doctor has told you to take half a tablet.
- It helps put you to sleep quite quickly. If you take SOMIDEM on an empty stomach it may work faster.
If you forget to use SOMIDEM
If you forget to take SOMIDEM before you go to bed, and you wake up late in the night or very early in the morning, do not take it. You may have trouble waking at your normal time.
If you are not sure what to do, ask your doctor.
If you use too much SOMIDEM
If you think that you have used too much SOMIDEM, you may need urgent medical attention.
You should immediately:
- phone the Poisons Information Centre
(Australia telephone 13 11 26) for advice, or - contact your doctor, or
- go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much SOMIDEM, your consciousness may be impaired, ranging from drowsiness to light coma.
5. What should I know while using SOMIDEM?
Things you should do
Tell all the doctors, dentists and pharmacists who are treating you that you are taking SOMIDEM.
If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking SOMIDEM.
If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking this medicine.
If you become pregnant or suspect that you are pregnant while you are taking SOMIDEM, stop taking it and tell your doctor or pharmacist immediately.
Call your doctor straight away if you:
- have any of the serious side effects listed in section 6
Remind any doctor, dentist or pharmacist you visit that you are using SOMIDEM.
Things you must not do
- Do not take more than the recommended dose unless your doctor tells you to. This can increase the risk of side effects.
- Do not give this medicine to anyone else, even if they have the same condition as you.
- Do not use this medicine to treat any other complaints unless your doctor tells you to.
- Do not drink alcohol before or after taking this medicine. This can increase the risk of side effects.
Things to be careful of
- Be careful if you are over 65 and unwell or taking other medicines. You may be more sensitive to some of the side effects of SOMIDEM. Some patients may be particularly susceptible to the sedative effects of this medication, which may increase the possibility of a fall.
After taking SOMIDEM
- Sleep medicines should, in most cases, be used only for short periods of time. If your sleep problems continue, consult your doctor.
- Some medicines can cause dependence, especially when they are used regularly for longer than a few weeks. People who have been dependent on alcohol or other drugs in the past may have a higher chance of becoming addicted to sleep medicines. If you have been addicted to alcohol or drugs in the past, it is important to tell your doctor before starting SOMIDEM.
- Sometimes when medicines are stopped suddenly, after being used for a long time, withdrawal symptoms may occur. Symptoms of withdrawal may include abdominal and muscle cramps, vomiting and sweating. In some cases, your insomnia may appear worse for a short time which may be accompanied with other reactions including mood changes, anxiety and restlessness; speak to your doctor if this occurs. Patients taking part in trials have not had any problems when they stopped taking SOMIDEM. However, let your doctor know if you have any problems when you stop taking SOMIDEM.
Driving or using machines
Because SOMIDEM will make you sleepy, you should not operate dangerous machinery or drive motor vehicles for 8 hours after you take it. You should also be careful the next morning when you wake up.
Make sure you know how you react to SOMIDEM before you drive a car or operate machinery. This is very important if you are taking other drugs that also make you drowsy.
Drinking alcohol
You should not drink alcohol while you are taking SOMIDEM.
Tell your doctor if you drink alcohol.
The effects of alcohol could be made worse while taking SOMIDEM.
Looking after your medicine
- Keep your tablets in the pack until it is time to take them. If you take the tablets out of the pack they may not keep well.
- Keep your tablets in a cool dry place where the temperature stays below 25°C.
Follow the instructions in the carton on how to take care of your medicine properly.
Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:
- in the bathroom or near a sink, or
- in the car or on window sills.
Keep it where young children cannot reach it.
Getting rid of any unwanted medicine
If you no longer need to use this medicine or it is out of date, take it to any pharmacy for safe disposal.
Do not use this medicine after the expiry date.

See the information below and, if you need to, ask your doctor or pharmacist if you have any further questions about side effects.
Tell your doctor as soon as possible if you do not feel well while you are taking SOMIDEM.

Alcohol can increase the risk of sleep walking and other related behaviours. These side effects can also occur without the presence of alcohol. Although these side effects can occur at the usual recommended doses, the risk of these behaviours occurring may also be increased if you take more than the recommended dose.
Some sleep medicines may cause short-term memory loss. When this occurs, a person may not remember what has happened for several hours after taking the medicine. This is usually not a problem since most people fall asleep after taking the medicine.
Tell your doctor or pharmacist if you notice anything else that may be making you feel unwell.
Other side effects not listed here may occur in some people.
