What is in this leaflet

This leaflet answers some common questions about STILDEM

It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking STILDEM against the benefits they expect it will have for you.

What STILDEM is used for

STILDEM is used to initiate and maintain sleep in those with sleeping difficulties, also called insomnia.

STILDEM works by binding to special sites in the brain which produce sleep. It has a different chemical structure to other sleeping tablets.

In general, sleeping tablets such as STILDEM are not recommended for use for more than 4 weeks at a time.

Ask your doctor if you have any questions about why STILDEM was prescribed for you.

STILDEM is only available with a prescription.

How to take STILDEM

How much to take

STILDEM 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. The usual adult dose of STILDEM is 10 mg (one tablet). If you are over 65 years of age, the dose is 5 mg (half a STILDEM tablet).

If you have a liver problem, you should start with 5 mg STILDEM at night. If necessary, this can then be increased to 10 mg.

Follow all directions given to you by your doctor and pharmacist carefully.

How to take it

Swallow the tablet with water or other liquid. STILDEM tablets can be broken in half.

Take STILDEM immediately before you go to bed. It helps puts you to sleep quite quickly. It works more quickly if you take it on an empty stomach.

If you are not sure when to take it ask your doctor or pharmacist.

How long to take it

Usually, STILDEM 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.

If you forget to take your dose

If you forget to take STILDEM before you go to bed and you wake up late in the night or early morning, do not take any STILDEM as you may have trouble waking later in the morning.

If you are not sure what to do or have any questions, ask your doctor or pharmacist.

If you take too much (overdose)

Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much STILDEM.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too much STILDEM your consciousness may be impaired, ranging from drowsiness to light coma.

While you are taking it

Things you must do

Tell all the doctors, dentists and pharmacists who are treating you that you are taking STILDEM.

If you are about to be started on any new medicine, tell your doctor or pharmacist that you are taking STILDEM.

If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking STILDEM.

Tell your doctor if you become pregnant or intend to become pregnant while taking STILDEM.

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 use STILDEM to treat any other complaints unless your doctor says so.

Do not give STILDEM to anyone else, even if they have the same or similar condition as you.

Do not drink alcohol before or after taking this medicine. This can increase the risk of side effects.

Things to be careful of

Because STILDEM will make you sleepy, you should not operate dangerous machinery or drive a motor vehicle 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 STILDEM before you drive a car or operate machinery. This is very important if you are taking other drugs that also make you drowsy.

Be careful if you are elderly, unwell or taking other medicines. You may be more sensitive to some of the side effects of STILDEM.

Some patients may be particularly susceptible to the sedative effects of the medication, which may increase the possibility of a fall.

You should not drink alcohol while taking STILDEM. The effects of alcohol could be made worse while you are taking STILDEM.

Side Effects

Like all medicines, STILDEM can have unwanted side effects in some people. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

Tell your doctor if you notice any of the following and they worry you:

  • drowsiness
  • dizziness
  • headache
  • fatigue
  • worsened insomnia
  • nightmares
  • hallucinations
  • agitation
  • depression
  • diarrhoea, nausea or vomiting
  • abdominal pain
  • back pain
  • muscle weakness
  • infections of the nose, throat, or chest.

These are the most common side effects of STILDEM.

Less common side effects include:

  • unexpected changes in behaviour. These have included rage reactions, confusion, and other forms of unwanted behaviour
  • sleep walking, driving motor vehicles and other unusual and on some occasions, dangerous behaviours whilst apparently asleep. These have also included preparing and eating food, making phone calls or having sexual intercourse. People experiencing these effects have had no memory of the events.

While these effects can occur at prescribed doses, drinking alcohol or taking more than the recommended dose, increases the risk of sleep walking or other behaviours such as driving or eating food whilst asleep.

Some sleep medicines may cause short-term memory loss. When this occurs, a person may not remember what happened for several hours after taking the medicine. This is usually not a problem since most people fall asleep after taking the medicine.

Sleep medicines should in most cases, be used for only 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 taking STILDEM.

Tell your doctor immediately or go to Accident and Emergency at the nearest hospital if you notice any of the following soon after taking STILDEM:

  • swelling of the face, lips, mouth or throat which may cause difficulty in swallowing or breathing
  • hives
  • fainting.

These are very serious side effects. You may need urgent medical attention or hospitalisation. All of these side effects are very rare.

Other side effects not listed above may also occur in some people. Tell your doctor if you notice anything that is making you fell unwell.

After taking it

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; speak to your doctor if this occurs.

However, let your doctor know if you have any problems when you stop taking STILDEM

If you have any queries about any aspect of your medicine, or any questions regarding the information in this leaflet, discuss them with your doctor or pharmacist.


Keep STILDEM where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good way to store medicines.

Keep your STILDEM in the pack until it is time to take them. If you take the tablets out of the pack, they may not keep as well.

Keep STILDEM in a cool dry place where the temperature stays below 25°C.

Do not store STILDEM or any other medicines in the bathroom or near a sink.

Do not leave STILDEM in the car or on window sills. Heat and dampness can destroy some medicines.


If your doctor tells you to stop taking STILDEM or the tablets have passed their expiry date, ask you pharmacist what to do with any that are left over.
