1. What Cloranxen is and what it is used for

Cloranxen contains the active substance dipotassium clorazepate. Clorazepate belongs to a group of medicines called benzodiazepines. It has anxiolytic, sedative, and hypnotic effects.
The indications for the use of Cloranxen are:

• short-term treatment of anxiety and restlessness, as an adjunct in the course of neurosis
• alcohol withdrawal syndrome (delirium tremens, pre-delirium states).

Cloranxen is indicated only when symptoms are severe, disrupt normal functioning, or are very troublesome for the patient.

2. Important information before taking Cloranxen

• if you have muscle weakness (myasthenia gravis)
• severe respiratory failure
• sleep apnea syndrome
• severe liver failure
• narrow-angle glaucoma.

The medicine is contraindicated in children under 12 years of age.

Warnings and precautions

Before starting treatment with Cloranxen, discuss it with your doctor or pharmacist.
The medicine may cause psychological and physical dependence, and its use should be under close medical supervision and, in most cases, limited in time. The risk of dependence increases with the dose and duration of treatment, and is higher in patients with a history of alcohol, drug, or other substance abuse, as well as in patients taking other psychotropic, anxiolytic, or hypnotic medicines. Particular caution is required when administering the medicine to patients suspected of having a tendency to abuse medicines or alcohol.
The duration of treatment should be limited and not exceed 4 weeks, including the period of dose reduction. The doctor will inform the patient how to stop therapy (gradually reducing the dose of the medicine).
Sudden withdrawal may cause a withdrawal syndrome characterized by muscle tremors, agitation, insomnia, hallucinations, disorientation, derealization (feeling of change in the surrounding world), depersonalization (feeling of change in one's own image), headaches, muscle pain, anxiety, irritability, seizures, hypersensitivity to light, sound, and physical contact. These symptoms may occur 4-8 days after stopping the medicine.
Stopping treatment, especially suddenly, may cause insomnia and anxiety "rebound". Gradual withdrawal of the medicine is recommended.
During long-term use, tolerance to the medicine (reduced efficacy) may develop.
During treatment with the medicine, anterograde amnesia may occur, especially when taking benzodiazepines directly before going to sleep and in the case of short sleep duration (early awakening caused by external factors).
Benzodiazepines should not be used as the only treatment for depression or anxiety associated with depression (in these patients, the risk of suicidal attempts may occur).
The medicine should not be used to treat mental disorders.
Paradoxical reactions are occasionally observed: anxiety, irritability, aggression, euphoria, agitation, hallucinations, insomnia, psychoses, inappropriate behavior. These reactions occur especially in children and elderly patients.
During treatment with clorazepate, it is not recommended to consume alcoholic beverages.
In elderly patients and patients with kidney disease, it may be necessary to adjust the dose of the medicine.
The medicine should be used with caution in patients with liver failure and in patients with respiratory failure.
Concomitant use of several benzodiazepines is not beneficial and may increase the risk of dependence.

Cloranxen and other medicines

Tell your doctor or pharmacist about all medicines you are taking or have recently taken, as well as medicines you plan to take.
The risk of withdrawal symptoms increases when other benzodiazepines with anxiolytic and hypnotic effects are used concomitantly.
Concomitant use of Cloranxen and opioids (strong painkillers, substitution therapy for addiction, and some antitussive medicines) increases the risk of sedation, respiratory depression, coma, and can be life-threatening. For this reason, concomitant use of these medicines can only be considered when other treatment options are not possible.
If the doctor prescribes Cloranxen with opioids, the dose and duration of concomitant treatment should be limited.
Tell your doctor about all opioid medicines you are taking and strictly follow the dosage recommended by your doctor. It may be helpful to inform friends or relatives about these symptoms. If such symptoms occur, contact your doctor.
Alcohol
During treatment, avoid consuming alcohol and taking medicines containing alcohol.
Alcohol enhances the sedative effect of benzodiazepines. This can lead to decreased concentration and impaired ability to drive vehicles and operate machinery.
The medicine acts synergistically with muscle relaxants (curare and its derivatives, drugs reducing skeletal muscle tone).
It enhances the effect of other medicines acting on the central nervous system (psychotropic, opioid analgesics, barbiturates, some antidepressants, hypnotics, antihistamines with sedative effects, other sedatives, neuroleptics, anesthetics, anticonvulsants, anxiolytics). Increased inhibitory effect on the central nervous system may cause impaired ability to drive vehicles and operate machinery.
In the case of concomitant use of opioid analgesics with clorazepate, euphoria may be enhanced, leading to psychological dependence.
Cisapride (a medicine stimulating intestinal motility) temporarily enhances the sedative effect of benzodiazepines due to increased absorption. Cimetidine enhances sedation after clorazepate.
It is difficult to predict interactions with phenytoin. Phenytoin levels in serum may increase, and adverse effects may be enhanced. It is also possible that phenytoin levels may decrease or there may be no interaction. Clorazepate reduces the effect of levodopa.
Clorazepate metabolism is generally accelerated in smokers and people taking anticonvulsant medicines. Antacids (aluminum and magnesium hydroxides and salts) may sometimes significantly delay clorazepate absorption, but usually without changing its absolute bioavailability.

Cloranxen with food and drink

The medicine can be taken regardless of meal times.

Pregnancy, breastfeeding, and fertility

Pregnancy

Before taking any medicine, consult your doctor or pharmacist.
The medicine should not be used during pregnancy, especially in the first and third trimesters.
The doctor should inform women of childbearing age about potential risks. If a woman plans to become pregnant, treatment should be stopped in advance. If the medicine is administered for important reasons at the end of the third trimester of pregnancy or during labor, the newborn may experience: hypothermia (lowered body temperature), hypotonia (lowered muscle tone), respiratory depression. In newborns of mothers taking clorazepate in the last period of pregnancy, physical dependence may develop, and there is a risk of withdrawal symptoms.

Breastfeeding

Before taking any medicine, consult your doctor or pharmacist.
The medicine and its metabolites pass into breast milk. Clorazepate should not be used in breastfeeding mothers.

Driving and using machines

The medicine may impair psychophysical fitness, ability to drive vehicles, and perform other complex tasks requiring concentration.

Cloranxen contains lactose.

If you have been diagnosed with intolerance to some sugars, you should contact your doctor before taking the medicine.

3. How to take Cloranxen

Always take this medicine exactly as your doctor or pharmacist has told you. If you are not sure, ask your doctor or pharmacist.
Treatment should be started with an initial dose, gradually increasing the dose to avoid side effects. Do not exceed the maximum dose of 30 mg per day. The duration of treatment should be as short as possible and not exceed 4 weeks, including the period of dose reduction. During treatment, the patient should be regularly monitored to potentially reduce the dose or frequency of administration of the medicine. Due to the possibility of withdrawal symptoms, the medicine should be withdrawn carefully, gradually reducing the daily dose.
Adults
Therapeutic dose: 5 mg to 30 mg per day.
Treatment is recommended to be started with a dose of 5 mg per day.
The daily dose can be taken once a day, in the evening.
Use in children and adolescents
Cloranxen is not recommended for use in children and adolescents (see also section 2).
Only in exceptional cases, justified by a specialist doctor, can it be used in children over 12 years of age: at a dose of 0.5 mg/kg body weight per day in divided doses.
Use in elderly patients or patients with kidney disease
The dose of the medicine should be reduced by half, and treatment should be as short as possible.

Overdose of Cloranxen

Overdose is characterized by various degrees of inhibition of central nervous system function: from moderate sedation to coma.
In the case of slight overdose, the following symptoms occur: sedation, disorientation, lethargy; in severe overdose: ataxia, muscle hypotonia, hypotension, respiratory depression, rarely coma, and very rarely death. In addition to general principles of oral poisoning (removal of stomach contents, depending on the patient's condition - inducing vomiting or gastric lavage, administration of activated charcoal, maintenance of respiratory and cardiovascular function), in the case of severe poisoning with coma or respiratory failure, the benzodiazepine receptor antagonist flumazenil can be administered intravenously as an antidote.
The use of flumazenil as an antidote is contraindicated in the case of: use of tricyclic antidepressants, concomitant administration of medicines lowering the seizure threshold, ECG disturbances in the form of prolonged QRS or QT interval (suggesting concomitant use of tricyclic antidepressants).
Although benzodiazepine overdose is rarely life-threatening, one should never forget that the patient may have taken the medicine with alcohol or other substances acting on the central nervous system.

Missed dose of Cloranxen

In the case of a missed dose of Cloranxen, take the next dose at the usual time.
Do not take a double dose to make up for the missed dose.
If you have any doubts about taking the medicine, ask your doctor or pharmacist.
