What Is Revia?
Revia is a brand name for the medication naltrexone hydrochloride, which belongs to a class of drugs known as opioid antagonists. It is primarily used in the management of alcohol dependence and, after detoxification, to prevent relapse in individuals who have been dependent on opioids. In Denmark, as in many other countries, Revia is approved for use alongside psychosocial support as part of a comprehensive treatment plan.
The medication works by blocking the effects of opioids at receptor sites in the brain. For alcohol dependence, its exact mechanism is not fully understood, but it is thought to reduce the rewarding sensations associated with drinking, thereby decreasing the desire to consume alcohol. It does not cause physical dependence, nor does it produce a “high” on its own.
Revia is available in tablet form and is typically taken once daily. It is not a cure for addiction but rather a tool that can help individuals maintain abstinence or reduce harmful drinking patterns. Because it requires a prescription, initiating treatment involves a thorough medical evaluation to ensure suitability and safety.
How the Revia Option Supports Recovery
When integrated into a structured recovery programme, the Revia option offers pharmacological reinforcement for behavioural changes. By dampening the brain’s reward response to alcohol or opioids, it can make it easier for a person to focus on counselling, lifestyle adjustments, and the psychological aspects of recovery. This dual approach is often more effective than either strategy alone.
For individuals who have completed opioid detoxification, naltrexone helps block the euphoric effects should a relapse occur, which can reduce the motivation to misuse opioids. In the context of alcohol use disorder, patients often report a reduction in cravings and a decreased likelihood of heavy drinking episodes.

Adherence to the regimen is crucial for success. The Revia option is usually prescribed for a period of months, with regular follow‑ups to monitor progress and adjust the treatment plan if necessary. It is important to note that the medication is not suitable during active opioid use or in the presence of acute withdrawal, as it can precipitate severe symptoms.
Who Can Benefit from Revia?
Revia is typically recommended for adults who have been diagnosed with alcohol dependence and are committed to reducing their intake. It is also considered for those recovering from opioid dependence, but only after they have been opioid‑free for a sufficient period—usually seven to ten days—to avoid withdrawal complications.
The ideal candidates are often individuals who:
- Have strong motivation to stop or significantly cut down their substance use.
- Are engaged in a comprehensive treatment programme that includes psychosocial therapy.
- Do not have acute liver problems, as naltrexone can affect liver function.
- Are not currently using opioid pain medications or illicit opioids.
Before starting Revia, a healthcare professional will conduct blood tests to check liver enzymes and rule out any contraindications. People with acute hepatitis or liver failure generally should not take the medication. Pregnant or breastfeeding women are also advised against using naltrexone unless the potential benefits clearly outweigh the risks.
Because the drug blocks opioid receptors, it can interfere with opioid‑based pain relief. Patients should carry a medical alert card and inform all healthcare providers that they are taking naltrexone so that alternative pain management strategies can be planned in case of emergency.
What the Research Shows
Clinical trials have demonstrated that naltrexone, when combined with behavioural support, can significantly reduce the frequency and severity of relapse in alcohol‑dependent individuals. Many studies report a measurable decline in the number of heavy drinking days and an increase in the proportion of days abstinent compared to placebo. The evidence is strongest when the medication is taken consistently for at least three months.
For opioid‑use disorder, research indicates that naltrexone is effective in preventing relapse once detoxification is complete. However, because it requires a period of abstinence before initiation, it may be less suitable for patients who struggle to achieve initial detoxification compared to agonist medications like buprenorphine. The choice of therapy is therefore highly individual and depends on the person’s circumstances and preferences.
Long‑term outcomes are most favourable when pharmacological treatment is paired with psychosocial interventions, such as cognitive‑behavioural therapy or motivational interviewing. The overall success rate varies, but even modest improvements in drinking or opioid‑use patterns can translate into meaningful health and social gains.
Side Effects and Safety Considerations
Most people tolerate Revia well, but like any medication, it can cause side effects. The most commonly reported ones are relatively mild and often diminish after the first few weeks of use. A summary of typical side effects and those requiring prompt medical attention is presented in the table below.
| Category | Examples and Notes |
|---|---|
| Common side effects | Nausea, headache, dizziness, fatigue, difficulty sleeping, and abdominal discomfort. These are usually temporary. |
| Serious side effects (rare) | Liver function changes (yellowing of the skin or eyes, dark urine), severe allergic reactions (rash, swelling), or depressed mood. Contact a doctor immediately if these occur. |
Because naltrexone is metabolised by the liver, regular monitoring of liver enzymes is recommended, especially in the initial phase of treatment or in patients with pre‑existing liver conditions. Alcohol abstinence is also encouraged to minimise additional hepatic stress. Healthcare providers will typically perform blood tests before starting therapy and periodically thereafter.
An additional safety concern is the risk of accidental opioid overdose if a person decides to use opioids after a period on naltrexone. As tolerance may be reduced, even small doses can lead to life‑threatening respiratory depression. Patients must be counselled about this danger and understand that trying to overcome the blockade by taking larger amounts of opioids is extremely hazardous.
Obtaining Revia in Denmark
In Denmark, Revia and other naltrexone‑containing medicines are available only by prescription, which must be issued by a licensed physician. Treatment is usually initiated after a comprehensive assessment, often at a specialised addiction clinic or through the general practitioner. The process typically involves a physical examination, blood tests, and a discussion of the individual’s substance use history.
Once prescribed, the medication can be obtained at community pharmacies across the country. The cost may be covered partially by the Danish national health insurance, depending on the reimbursement rules and the patient’s annual medicine expenditure. It is advisable to consult the local pharmacy or the Danish Medicines Agency for up‑to‑date pricing and coverage details.
Although it may be technically possible to purchase medications online, caution is strongly advised. Buying prescription drugs without a valid prescription is illegal and unsafe. Counterfeit or substandard products can pose serious health risks. Always ensure that any online pharmacy has a physical address in Denmark and is authorised by the Danish Medicines Agency before considering a purchase.
