ReVia® Tablets for Alcohol Use Disorder

ReVia® is a brand of naltrexone tablets used as part of treatment programs for alcohol and opioid dependence. This page explains how the medicine works, who it suits, and how to use it safely. Ships from Canada to US for patients who pay without insurance.

What ReVia Is and How It Works

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

Naltrexone is an opioid receptor antagonist. It binds to mu-opioid receptors and blocks the euphoric effects of opioids. In alcohol use disorder, it can reduce reward responses linked to drinking. This helps patients stay engaged in counseling and structured support. Treatment is used together with psychosocial therapy; it is not a stand-alone cure.

People must be opioid-free before starting. Beginning therapy while physically dependent on opioids can trigger acute withdrawal. Clinicians often confirm opioid abstinence with history, urine testing, or a naloxone challenge when appropriate. This medicine may also lower tolerance to opioids; relapse to prior doses after stopping can increase overdose risk.

Who It’s For

Naltrexone is indicated as part of a comprehensive plan for adults with alcohol use disorder. It is also used to maintain abstinence in individuals with opioid use disorder who have completed detoxification. Behavioral therapy, mutual-help groups, and ongoing follow-up remain essential components of care. See our category pages for background on Alcohol Use Disorder and Opioid Use Disorder.

Do not use this treatment if currently taking opioids, if withdrawal is expected, or if there is acute hepatitis or liver failure. Patients with liver disease, kidney impairment, or a history of depression should discuss risks with a healthcare professional. Use in pregnancy or while breastfeeding requires prescriber guidance based on potential benefits and risks.

Dosage and Usage

Standard labeling supports once-daily dosing. Many adults start with Naltrexone 50 mg each day. Some programs use supervised dosing schedules based on clinic protocols. Follow the directions from the prescriber and the patient information leaflet for the specific regimen.

Swallow tablets with water. Take with food if nausea occurs. Keep regular dosing times to support adherence. Counseling, relapse-prevention strategies, and monitoring by a clinician are integral to success. Do not attempt to overcome opioid blockade with higher opioid doses; this can be dangerous.

Strengths and Forms

Tablets are commonly supplied in one strength. Availability may vary by manufacturer and country.

• Tablets: 50 mg

Brand and generic presentations may differ in packaging. Pharmacists may source equivalent products approved by national regulators.

Missed Dose and Timing

If a dose is missed, take it when remembered the same day. If it is almost time for the next dose, skip the missed dose. Do not double up. Maintain consistent daily use alongside counseling and support services. If multiple doses are missed, contact the prescriber for guidance.

Storage and Travel Basics

Store tablets at room temperature in a dry place. Keep the bottle tightly closed and away from moisture. Protect from excessive heat and direct light. Keep out of reach of children and pets.

When traveling, carry the original labeled container in hand luggage. Pack only what you need plus a small buffer, and bring your prescription and clinic contact details. If crossing borders, a copy of the prescription and a medication list can help with screening questions. For home storage and travel, keep your medicine secure and avoid pill organizers if small children are present.

Benefits

This therapy blocks opioid effects and can reduce alcohol-related reward, which helps patients maintain abstinence or cut down drinking within structured programs. It has oral dosing and is non-addictive. The class can be used long term when tolerated, with periodic reassessment by the prescriber. ReVia tablets offer a familiar daily routine that fits into counseling and recovery plans.

Side Effects and Safety

• Nausea or stomach upset
• Headache
• Dizziness or tiredness
• Sleep changes
• Anxiety or restlessness
• Joint or muscle aches

Serious effects are uncommon but can include liver-related problems such as abdominal pain, dark urine, or yellowing of skin or eyes. Mood changes, including depression, can occur. Stop therapy and seek medical help if severe symptoms appear. After treatment, opioid sensitivity may increase; previously tolerated doses can cause overdose. For opioid emergencies, community programs may supply rescue devices such as Narcan® Nasal Spray.

Drug Interactions and Cautions

Do not use with opioid pain medicines, opioid cough syrups, or opioid antidiarrheals. Inform dentists and surgeons about naltrexone use before procedures. If opioid analgesia is required for acute pain, special supervision in a medical setting is recommended. Discuss use with other hepatotoxic agents, including some TB drugs or high-dose acetaminophen. Alcohol counseling and ongoing monitoring are important for those with past liver disease. See additional mental health resources under Mental Health.

What to Expect Over Time

Many patients find cravings easier to manage when therapy is combined with counseling. Benefits are tied to consistent use and strong psychosocial support. Clinicians may track alcohol use, withdrawal symptoms, and mood. The plan is reassessed regularly. If tolerability issues develop, prescribers may adjust timing or consider alternatives according to labeling.

Engagement with therapy, adherence tools, and scheduled follow-ups improve outcomes. Pill organizers, reminder apps, and supervised dosing can help when permitted by the care plan. Support groups and family involvement further encourage long-term progress.

Compare With Alternatives

Generic naltrexone offers the same active ingredient as branded tablets and may be a cost-conscious choice. See Naltrexone HCl for available presentations. Another FDA- and Health Canada–approved option for alcohol use disorder is acamprosate. It supports abstinence maintenance and is dosed three times daily.

Availability and Substitutions

Supply can differ by manufacturer and market. Pharmacists may dispense an equivalent naltrexone product approved by Health Canada if the branded pack is not available. Naltrexone from Canada follows national quality standards. If the brand is out of stock, a prescriber may recommend a suitable alternative based on the treatment plan. This process is prescription required and verified.

Patient Suitability and Cost-Saving Tips

Patients committed to recovery programs and opioid-free at initiation tend to be appropriate candidates. Those with active opioid use, acute hepatitis, or liver failure should avoid this therapy. Clinicians may check baseline liver enzymes and review all current medicines.

• Multi-month fills: reduce refills and often lower per-tablet costs
• Set reminders: support steady daily use
• Generic options: compare approved naltrexone equivalents
• Program support: pair medication with counseling for best results
• Travel prep: carry labeled bottles and prescriptions

Patients under structured care may use supervised dosing if adherence is challenging. Regular visits help monitor liver health, mood, and any side effects. For broader context on recovery, browse our category resources for Alcohol Use Disorder and Opioid Use Disorder.
