What is Revia (Naltrexone) Used For?

Revia (Naltrexone) is an opioid antagonist, primarily used to treat alcohol dependence and opioid dependence. In the treatment of opioid addiction, it is used to prevent relapse in individuals who have already undergone detoxification and have been opioid-free for at least seven to ten days. For alcohol dependence, it is used as part of a broader counseling program to help patients maintain abstinence and reduce the frequency of heavy drinking.

Revia works by blocking specific receptor sites in the brain that respond to opioids and natural reward chemicals. Its active ingredient, naltrexone, binds tightly to these receptors without activating them, effectively blocking the sites so other substances cannot trigger a response. When a person takes an opioid drug, Revia physically prevents the opioid molecules from attaching to the brain cells, which stops any high, euphoria, or pain relief from occurring. When a person drinks alcohol, the body normally releases reward chemicals called endorphins that trigger a pleasurable dopamine boost; Revia blocks those endorphins from attaching to the receptors, which removes the pleasurable feedback from drinking. Neutralizing the physical reward and intoxication of both opioids and alcohol helps reduce cravings and weakens the habit loop over time. This medication is specifically for opioid-free individuals, as it will trigger sudden and severe withdrawal if taken while opioids are still present in the body.

Be sure to take naltrexone exactly as prescribed by your healthcare provider. For more details about this medication, check out its product monograph.

What Side Effects Can Revia or Generic Naltrexone Cause?

The most frequent mild side effects experienced by individuals taking naltrexone include nausea, headaches, decreased appetite, trouble sleeping, vomiting, diarrhea, and dizziness. Other possible side effects include dry mouth, increased nervousness, somnolence, decreased sexual drive, muscle cramps, skin rashes, joint pain, constipation, and increased thirst. Contact your doctor if these mild side effects persist or worsen.

Serious side effects may include:
• Allergic reactions such as hives, swelling of the face, lips, tongue, or throat, or difficulty breathing or swallowing;
• Heart problems such as an abnormally fast heartbeat, fainting, or severe high blood pressure;
• Liver problems such as yellowing of the skin or eyes (jaundice), severe stomach pain, dark urine;
• Respiratory problems such as eosinophilic pneumonia with symptoms such as low blood oxygen levels, shortness of breath;
• Severe Mental Health Changes such as depression, severe anxiety, confusion, hallucinations, and suicidal ideation or behavior;

Also, if administered to someone who is not opioid-free, this medication can precipitate an abrupt and severe withdrawal syndrome characterized by confusion, visual hallucinations, and significant fluid loss from vomiting and diarrhea, which may necessitate hospitalization. Additionally, there is a risk of fatal opioid overdose if an individual attempts to overcome this drug's blockade with high doses of opioids or if they become hypersensitive to lower doses after stopping treatment.

Seek immediate medical attention if you experience any of these serious side effects. Also, inform your doctor about any other side effects you notice that are not listed here.

Warnings

Do not use this medication if you are:
• Allergic to naltrexone or any other ingredients in Revia;
• Currently taking an opioid medication or in acute opioid withdrawal;

Use this medication with caution in individuals with some specific medical conditions such as:
• Heart problems;
• Kidney disease;
• Liver disease;
• Mental or mood disorders such as depression with suicidal thoughts;

Your doctor will establish whether you have an existing liver disease before starting treatment, and you will need to perform monthly blood tests, including liver function tests, during the first six months to monitor for liver injury and this medication’s effects on your liver. Medications such as bremelanotide can decrease the absorption and levels of oral naltrexone, potentially leading to treatment failure. Therefore, do not use it along with naltrexone. Conversely, avoid medications like naldemedine and naloxegol because they can cause additive effects at opioid receptors, significantly increasing the risk of sudden opioid withdrawal. Therefore, inform your doctor about any other medications you are currently taking, including herbal medicines and supplements, to determine if it is safe to use along with naltrexone.

Controlled studies in pregnant women are insufficient, but animal research indicates a risk of early pregnancy loss at high doses. Doctors generally reserve Revia during pregnancy for only situations where the maternal benefits of treating substance dependence clearly outweigh the potential risks to the fetus. Also, as there is no data on the specific effects of the drug on a breastfed infant or on milk production, it should only be administered to breastfeeding mothers if the clinical need justifies the potential risks to the baby. Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children.
