1. Why am I using STILDEM?

STILDEM contains the active ingredient zolpidem tartrate. STILDEM is used to initiate and maintain sleep in those with sleeping difficulties, also called insomnia in patients over 18 years of age. It is not recommended for use for more than 4 weeks at a time.

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

Your doctor, however, may prescribe STILDEM for another purpose.

When to take / use STILDEM

  • Take STILDEM immediately before you go to bed or while you are in bed
  • 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. It should be taken in one dose and not be re-administered during the same night.

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.

5. What should I know while using STILDEM?

Things you should 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 and 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 this medicine.

If you become pregnant or suspect that you are pregnant while you are taking this medicine, stop taking it and tell your doctor or pharmacist immediately.

Call your doctor straight away if you:

  • have any serious side effects listed in Section 6

Remind any doctor, dentist or pharmacist you visit that you are using STILDEM.

Things you should not do

  • Do not stop using this medicine suddenly 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 or the effects of alcohol could be made worse while taking STILDEM.

Things to be careful of

  • If you are over 65 and 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.

After taking STILDEM

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

Driving or using machines

Because STILDEM 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 STILDEM 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 STILDEM.

Tell your doctor if you drink alcohol.

Alcohol may increase the risk of side effects or the effects of alcohol could be made worse while taking STILDEM.
