    At an initial visit, the patient’s clinical status, alcohol dependence, and level of alcohol consumption (based on patient reporting) should be evaluated. Thereafter, the patient should be asked to record his or her alcohol consumption for approximately two weeks.
    At the next visit, Selincro may be initiated in patients who continued to have a high DRL over this two-week period, in conjunction with psychosocial intervention focused on treatment adherence and reducing alcohol consumption.
    Selincro is to be taken as-needed: On each day the patient perceives a risk of drinking alcohol, one tablet should be taken, preferably 1-2 hours prior to the anticipated time of drinking. If the patient has started drinking alcohol without taking Selincro, the patient should take one tablet as soon as possible.
    The maximum dose of Selincro is one tablet per day. Selincro can be taken with or without food.
    During pivotal trials the greatest improvement was observed within the first 4 weeks. The patient’s response to treatment and the need for continued pharmacotherapy should be evaluated on a regular (for example, monthly) basis. The physician should continue to assess the patient’s progress in reducing alcohol consumption, overall functioning, treatment adherence, and any potential side effects. Clinical data for the use of Selincro under randomised controlled conditions are available for a period of 6 to 12 months. Caution is advised if Selincro is prescribed for more than 1 year.
    Elderly (≥65 years of age): No dose adjustment is recommended for this patient population.
    Renal impairment: No dose adjustment is recommended for patients with mild or moderate renal impairment.
    Hepatic impairment: No dose adjustment is recommended for patients with mild or moderate hepatic impairment.
    Paediatric population: The safety and efficacy of Selincro in children and adolescents <18 years of age have not been established. No data are available.
    Method of administration: Selincro is for oral use.
    The film-coated tablet should be swallowed whole.
    The film-coated tablet should not be divided or crushed because nalmefene may cause skin sensitisation when in direct contact with the skin.


    Reduction of alcohol consumption in adult patients with alcohol dependence who have a high drinking risk level (DRL), without physical withdrawal symptoms and who do not require immediate detoxification.
    This drug should only be prescribed in conjunction with continuous psychosocial support focused on treatment adherence and reducing alcohol consumption.
    Should be initiated only in patients who continue to have a high DRL two weeks after initial assessment.


    Hypersensitivity to the active substance.
    Patients taking opioid agonists (such as opioid analgesics, opioids for substitution therapy with opioid agonists (e.g. methadone) or partial agonists (e.g. buprenorphine).
    Patients with current or recent opioid addiction.
    Patients with acute symptoms of opioid withdrawal.
    Patients for whom recent use of opioids is suspected.
    Patients with severe hepatic impairment (Child-Pugh classification).
    Patients with severe renal impairment (eGFR<30 ml/min per 1.73 m²).
    Patients with a recent history of acute alcohol withdrawal syndrome (including hallucinations, seizures, and delirium tremens).

    Special Precautions

    Selincro is not for patients for whom the treatment goal is immediate abstinence. Reduction of alcohol consumption is an intermediate goal on the way to abstinence.
    Opioid administration: In an emergency situation when opioids must be administered to a patient taking Selincro, the amount of opioid required to obtain the desired effect may be greater than usual. The patient should be closely monitored for symptoms of respiratory depression as a result of the opioid administration and for other adverse reactions.
    If opioids are needed in an emergency, the dose must always be titrated individually. If unusually large doses are required, close observation is necessary.
    Selincro should be temporarily discontinued for 1 week prior to the anticipated use of opioids, for example, if opioid analgesics might be used during elective surgery.
    The prescriber should advise patients that it is important to inform their health care professional of last Selincro intake if opioid use becomes necessary.
    Caution should be exercised when using medicinal products containing opioids (for example, cough medicines, opioid analgesics).
    Psychiatric disorders: Psychiatric effects were reported in clinical studies. If patients develop psychiatric symptoms that are not associated with treatment initiation with Selincro, and/or that are not transient, the prescriber should consider alternative causes of the symptoms and assess the need for continuing treatment with Selincro.
    Selincro has not been investigated in patients with unstable psychiatric disease. Caution should be exercised if Selincro is prescribed to patients with current psychiatric comorbidity such as major depressive disorder.
    The increased suicidal risk in alcohol and substances abusers, with or without accompanying depression, is not reduced by the intake of nalmefene.
    Seizure disorders: There is limited experience in patients with a history of seizure disorders, including alcohol withdrawal seizures.
    Caution is advised if treatment aimed at reduction of alcohol consumption is started in such patients.
    Renal or hepatic impairment: Selincro is extensively metabolised by the liver and excreted predominantly in the urine.
    Therefore, caution should be exercised when prescribing Selincro to patients with mild or moderate hepatic or mild or moderate renal impairment, for example, by more frequent monitoring.
    Caution should be exercised when prescribing Selincro to patients with elevated ALAT or ASAT (>3 times ULN) as these patients were excluded from the clinical development programme.
    Elderly patients (≥65 years of age): Limited clinical data are available on the use of Selincro in patients ≥65 years of age with alcohol dependence.
    Caution should be exercised when prescribing Selincro to patients ≥65 years of age.
    Others: Caution is advised if Selincro is co-administered with a potent UGT2B7 inhibitor.
    Lactose: Patients with rare hereditary problems of galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption should not take this medicinal product.

    Side Effects

    The most common adverse reactions were nausea, dizziness, insomnia, and headache. The majority of these reactions were mild or moderate, associated with treatment initiation, and of short duration.
    See prescribing information for full details.

    Drug interactions

    No in vivo drug-drug interaction studies have been conducted.
    Based on in vitro studies, no clinically relevant interactions between nalmefene, or its metabolites, and concomitantly administered medicinal products metabolised by the most common CYP450 and UGT enzymes or membrane transporters are anticipated. Coadministration with medicinal products that are potent inhibitors of the UGT2B7 enzyme (for example, diclofenac, fluconazole, medroxyprogesterone acetate, meclofenamic acid) may significantly increase the exposure to nalmefene. This is unlikely to present a problem with occasional use, but if long-term concurrent treatment with a potent UGT2B7 inhibitor is initiated, a potential for an increase in nalmefene exposure cannot be excluded. Conversely, concomitant administration with a UGT inducer (for example, dexamethasone, phenobarbital, rifampicin, omeprazole) may potentially lead to subtherapeutic nalmefene plasma concentrations.
    If Selincro is taken concomitantly with opioid agonists (for example, certain types of cough and cold medicinal products, certain antidiarrhoeal medicinal products, and opioid analgesics), the patient may not benefit from the opioid agonist.
    There is no clinically relevant pharmacokinetic drug-drug interaction between nalmefene and alcohol. There seems to be a small impairment in cognitive and psychomotor performance after administration of nalmefene. However, the effect of nalmefene and alcohol in combination did not exceed the sum of the effects of each substance when taken alone.
    Simultaneous intake of alcohol and Selincro does not prevent the intoxicating effects of alcohol.

    Pregnancy and Lactation

    Pregnancy: There are no or limited data (fewer than 300 pregnancy outcomes) from the use of Nalmefene in pregnant women. Selincro is not recommended during pregnancy.
    Lactation: It is unknown whether Nalmefene is excreted in human milk. A risk to newborns/infants cannot be excluded.
    A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from Selincro therapy, taking into account the benefit of breast-feeding to the child and the benefit of therapy to the woman.
    See prescribing information for full details.


    In a study in patients diagnosed with pathological gambling, doses of nalmefene up to 90 mg/day for 16 weeks were investigated. In a study in patients with interstitial cystitis, 20 patients received 108 mg/day of nalmefene for more than 2 years. Intake of a single dose of 450 mg nalmefene has been reported without changes in blood pressure, heart rate, respiration rate, or body temperature.
    No unusual pattern of adverse reactions was observed in these settings, but experience is limited.
    Management of an overdose should be observational and symptomatic.

    Important notes

    The film-coated tablet should be swallowed whole. The film-coated tablet should not be divided or crushed because nalmefene may cause skin sensitisation when in direct contact with the skin.
    Storage: Store below 30ºC.
