Drugs List

  • loprazolam 1mg tablets
  • Therapeutic Indications


    Insomnia (short-term treatment)

    Short-term treatment of insomnia, including difficulty in falling asleep and/or frequent nocturnal awakenings. Only for use when insomnia is severe or disabling, or subjecting the individual to extreme distress.


    The lowest dose which can control the symptoms should be used.

    If possible, treatment should be intermittent; long term chronic use is not recommended. Treatment should not normally be continued beyond 4 weeks.

    Treatment should always be tapered off gradually. Patients who have taken benzodiazepines for a long time may require a longer period during which doses are reduced.


    1 mg at bedtime, increased to 1.5 mg or 2 mg if necessary.

    A starting dose of 0.5 mg may be appropriate in frail, debilitated or aged patients, and dosage should not exceed 1 mg in these populations


    Dosage in the elderly should be limited to 1 mg at bedtime.

    A starting dose of 0.5 mg may be appropriate in frail, debilitated or aged patients, and dosage should not exceed 1 mg in these populations.

    Suicide may be precipitated in patients who are depressed and who exhibit aggressive behaviour towards self and others.

    Dosage should be decreased gradually to avoid withdrawal symptoms. These are more likely if physical dependence has developed during usage. However, withdrawal symptoms can occur even with normal therapeutic doses given for short periods of time. Patients receiving benzodiazepines should be regularly monitored.

    Rebound insomnia and anxiety (a transient syndrome whereby the symptoms that led to treatment with a benzodiazepine recur in an enhanced form) may occur on withdrawal of treatment. The risk of this is greater after abrupt discontinuation; therefore gradual withdrawal is recommended.

    Pregnancy and Lactation


    Loprazolam should be used with caution in pregnancy.

    Benzodiazepines cross the placenta, and accumulation may occur in the neonate due to a low rate of metabolism. Some studies suggest a risk of malformations after exposure to benzodiazepines in the first trimester, such as cardiac malformations and facial clefts. Administration during the late phase of pregnancy, or during labour at high doses, may cause 'floppy infant syndrome' (hypothermia, hypotonia, sedation, sucking problems, apnoea and cyanosis). Neonatal dependence and withdrawal may also occur in infants of mothers who took benzodiazepines chronically during the latter stages of pregnancy. Data on the long-term effects of foetal exposure to benzodiazepines are scarce.

    However, benzodiazepines are among the drugs of first choice for the treatment of anxiety and sleeping disorders during pregnancy (Schaefer et al, 2007). They should be given at the lowest possible dose for the shortest time, and long-acting benzodiazepines should be avoided. Observe the neonate for respiratory depression, withdrawal symptoms or adaption problems, particularly when benzodiazepines have been used up to delivery.

    The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( ) or if this is unavailable at the backup site ( ).


    Loprazolam is contraindicated during breastfeeding.

    Diphenhydramine is the drug of choice for sleep disturbances during lactation, and short-acting benzodiazepines are preferred if their use is unavoidable. Single doses of benzodiazepines do not require any limitation of breastfeeding (Schaefer et al 2007). There is insufficient experience on the long-term effects on breastfed children as a result of ongoing therapy in their mothers. The CSM has recommended that benzodiazepines should not be given to breastfeeding mothers.

    Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
