Disinhibiting effects may be manifested in various ways. Suicide may be precipitated in patients who are depressed and who exhibit aggressive behaviour towards self and others. Extreme caution should therefore be used in prescribing benzodiazepines in patients with personality disorders.
In general, the dependence potential of benzodiazepines is low but this increases when high doses are attained, especially when given over long periods and particularly in patients with a history of alcoholism or drug abuse. Use of loprazolam may lead to the development of abuse and/or physical and psychological dependence. The risk of dependence increases with dose and duration of treatment; it is also greater in patients with a history of psychiatric disorders and/or alcohol or drug abuse. Therefore, loprazolam should be used with extreme caution in patients with current or a history of alcohol or drug abuse. However, withdrawal symptoms occur even with normal therapeutic doses given for short periods of time. Withdrawal from benzodiazepines may be associated with physiological and psychological symptoms of withdrawal including depression, anxiety, tension, restlessness, confusion, irritability and headaches. Patients receiving benzodiazepines should be regularly monitored.
Rebound insomnia may also occur. It may be accompanied by other reactions such as changes in mood, anxiety, sleep disturbances and restlessness. The cause of insomnia should be identified wherever possible and the underlying factors treated before a hypnotic is prescribed.
Loprazolam should be used with caution in chronic pulmonary insufficiency, cerebrovascular disease and chronic renal or hepatic impairment.
Risks from concomitant use of benzodiazepines and opioids
Concomitant use of benzodiazepines, including loprazolam, and opioids may result in sedation, respiratory depression, coma, and death. Because of these risks, reserve concomitant prescribing of benzodiazepines and opioids for use in patients for whom alternative treatment options are inadequate.
If a decision is made to prescribe loprazolam concomitantly with opioids, prescribe the lowest effective dosages and minimum durations of concomitant use, and follow patients closely for signs and symptoms of respiratory depression and sedation. (See Section 4.5)
Suicidal ideation/suicide attempt/suicide and depression
Some epidemiological studies suggest an increased incidence of suicidal ideation, suicide attempt and suicide in patients with or without depression, and treated with benzodiazepines and other hypnotics, including loprazolam. However, a causal relationship has not been established.
Fall
Due to its pharmacological properties, loprazolam can cause drowsiness and a decreased level of consciousness, which may lead to falls and consequently to severe injuries, especially in elderly (see section 4.8).
Excipients
Loprazolam contains lactose. Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.
