The name of your medicine is Loprazolam 1mg Tablets (called loprazolam throughout this leaflet). Loprazolam contains a medicine called loprazolam mesylate. This belongs to a group of medicines called hypnotics. It works by acting on your brain to help you sleep.

Loprazolam is used to treat sleep problems such as:

  • Difficulty falling asleep
  • Waking often during the night

Loprazolam is used for short term sleep problems.

Do not use long term. Treatment should be as short as possible because the risk of dependence increases with the duration of treatment.

Ask your doctor for advice if you are unsure.


Do not take this medicine and tell your doctor if:

  • You are allergic (hypersensitive) to loprazolam mesylate or any of the other ingredients of this medicine (listed in Section 6 below). Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue
  • You are allergic (hypersensitive) to other benzodiazepines such as nitrazepam or temazepam
  • You have a problem that causes severe muscle weakness (myasthenia gravis)
  • Your lungs do not work properly
  • You have heart problems
  • You suffer from depression, anxiety or mental problems including phobias and obsessive disorders
  • You have ever been addicted to alcohol
  • You have a problem where you stop breathing for short periods at night (sleep apnoea)

Do not take this medicine if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking loprazolam.

Warnings and precautions

Talk to your doctor or pharmacist before taking loprazolam if:

  • You have any liver problems
  • You have any kidney problems
  • You have a history of drug abuse
  • You have been told by your doctor that you have had or are likely to have a stroke
  • You have been told by a doctor that you have a personality disorder
  • You have recently taken loprazolam or other similar medicines for more than four weeks
  • You do not feel you will ever be able to stop taking loprazolam or other medicines used to treat sleep problems
  • You are taking medicines to relieve pain (opioids such as codeine, methadone, morphine, oxycodone, pethidine or tramadol). Your doctor will decide if you should receive loprazolam (see also ‘Other medicines’ section below).
  • You are elderly, as loprazolam can cause drowsiness and decreased consciousness which can lead to falls and severe injuries.

The risk of dependence is greater in patients with a history of mental disorders and/or alcohol or drug abuse. Tell your doctor or pharmacist if you have ever had a mental disorder, or have abused or have been dependent on alcohol or drugs.

Some studies have shown an increased risk of suicidal ideation, suicide attempt and suicide in patients taking certain sedatives and hypnotics, including this medicine.

However, it has not been established whether this is caused by the medicine or if there may be other reasons. If you have suicidal thoughts, contact your doctor as soon as possible for further medical advice.

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking loprazolam.

Other medicines and loprazolam

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because loprazolam can affect the way some other medicines work. Also some medicines can affect the way loprazolam works.

Tell your doctor if you are taking any of the following:

  • Medicines to treat stomach problems such as cisapride
  • Medicines which relax muscles (neuromuscular depressants). These are often used during operations or in Intensive Care Units.
  • Medicines for mental problems (antipsychotics)
  • Medicines for depression
  • Medicines for epilepsy (anticonvulsants)
  • Medicines used in surgery (anaesthetics)
  • Medicines to calm or reduce anxiety or for sleep problems (hypnotics)
  • Medicines for hay fever, rashes or other allergies that can make you sleepy (sedative antihistamines) such as chlorphenamine or promethazine
  • Some medicines for moderate to severe pain (narcotic analgesics) such as codeine, methadone, morphine, oxycodone, pethidine or tramadol

Taking loprazolam with food and drink

  • Do not drink alcohol while you are taking loprazolam.
  • Alcohol can increase the effects of loprazolam and make you sleep very deeply so that you do not breathe properly or have difficulty waking.

Pregnancy, breast-feeding and fertility

Use of this medicine is not recommended during pregnancy.

If you discover that you are pregnant or are planning to have a baby, consult your doctor right away to re-assess the need for treatment.

A large amount of data has not shown evidence of malformations associated with the use of benzodiazepines. However, some studies have shown a potentially increased risk of cleft lip and palate in newborn babies compared to that in the general population. Use of this medicine is not recommended during pregnancy.

Cleft lip and palate (sometimes called “harelip”) is a deformation at birth caused by incomplete fusion of the palate and upper lip.

Reduced fetal movement and fetal heart rate variability may occur after taking loprazolam during the second and/or third trimester of pregnancy.

If loprazolam is taken at the end of pregnancy, your baby may show muscle weakness (hypotonia or floppy infant syndrome), a drop in body temperature (hypothermia), difficulty feeding (problems suckling causing poor weight gain) and breathing problems (respiratory distress). If taken regularly in late pregnancy, your baby may get withdrawal symptoms such as agitation or shaking. In this case the newborn should be closely monitored during the postnatal period.

Do not take loprazolam if you are breast-feeding or planning to breast-feed. This is because small amounts may pass into mother’s milk.

Ask your doctor or pharmacist for advice before taking any medicine if you are pregnant or breast-feeding.

Driving and using machines

This medicine may cause drowsiness, lack of concentration, muscle weakness and memory loss. If this happens do not drive or use any tools or machines.

  • Do not drive while taking this medicine until you know how it affects you.
  • It is an offence to drive if this medicine affects your ability to drive.
