About zolpidem

Type of medicineHypnotic
Used forInsomnia
Also calledStilnoct®
Available asTablets

Zolpidem is used for a short period of time to help sleeping difficulties. It reduces the time it takes to fall asleep and increases the length of time spent sleeping. Zolpidem works by acting on the way the messages are sent in your brain which help you to sleep.

Zolpidem is not normally taken for more than 2-4 weeks. This is because your body gets used to this medicine within 3 to 14 days and after this time it is unlikely to have the same effect. Your body may also become dependent on it when it is taken for longer periods of time.

Before taking zolpidem

Before taking zolpidem make sure your doctor or pharmacist knows:

  • If you are pregnant or breast-feeding.
  • If you have sleep apnoea (a problem where you stop breathing for short periods at night) or any other breathing problems.
  • If you are feeling depressed, or have any other mental health problem.
  • If you have severe muscle weakness such as in myasthenia gravis.
  • If you have ever been addicted to drugs or alcohol.
  • If you have kidney or liver problems.
  • If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
  • If you have ever had an allergic reaction to this or any other medicine.
