ReVia® Tablets for Alcohol Use Disorder

ReVia is a prescription tablet for alcohol dependence and for blocking the effects of opioids. This page helps you understand how it works, safe use, and what to discuss with your clinician. You can compare options for ReVia® without insurance while planning US delivery from Canada.

What ReVia Is and How It Works

This medicine contains naltrexone, an opioid receptor antagonist. It attaches to opioid receptors without activating them. In alcohol use disorder, it may reduce the reward response to drinking. In opioid use disorder, it blocks opioid effects if taken after detoxification. It is used with counseling and support programs.

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

Naltrexone does not treat acute opioid withdrawal and is not an opioid. Starting too soon after opioid use can precipitate withdrawal. Your clinician will confirm an opioid-free interval before the first dose.

Who It’s For

This treatment is indicated for adults with alcohol dependence who aim to reduce drinking or maintain abstinence with psychosocial support. It is also used to block the effects of exogenous opioids after detoxification.

It should not be used if you are currently using opioids, are in acute opioid withdrawal, or have a positive opioid screen. People with acute hepatitis or liver failure should not use it. Tell your clinician about liver disease, pregnancy, breastfeeding, and all medicines you take.

Dosage and Usage

Follow your prescriber’s directions and the official label. Adults commonly take a single daily dose with or without food. Many programs use once-daily dosing with a consistent schedule to support adherence. Some clinicians may use supervised dosing when appropriate.

When discussing your plan, ask how to integrate counseling, support groups, and regular check-ins. Take tablets whole with water. If stomach upset occurs, taking with food may help. Avoid all opioid-containing medicines unless your prescriber specifically instructs otherwise. Programs often include a medical identification card noting opioid blockade.

Label-based dosing often involves Naltrexone 50 mg tablets once daily for maintenance after appropriate screening. Your clinician may perform a naloxone challenge or urine test to confirm opioid abstinence before starting.

Strengths and Forms

Oral tablets are widely available. The commonly published strength is 50 mg. Brand and generic presentations may differ in packaging, but the active ingredient is the same. Availability can vary by supplier and jurisdiction.

Check the product page to see current stock, packaging details, and manufacturer information. If a specific brand is unavailable, your prescriber may authorize a therapeutically equivalent generic.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to the next scheduled time. Do not double up doses. Resume your usual schedule with the next dose. Staying consistent helps maintain receptor blockade and supports your counseling plan.

If you miss several doses, speak with your clinician about how to restart. Keep a simple routine, such as taking your tablet after breakfast or with another daily habit, to reduce missed doses.

Storage and Travel Basics

Store tablets at room temperature in the original container, away from excess moisture and light, and out of reach of children and pets. Keep the container closed tightly. Do not store in a hot car or steamy bathroom. Use child-resistant caps and consider a lockbox at home if others have access.

For travel, carry your labeled container and a copy of your prescription. Keep a small supply in a separate bag as a backup. Time-zone changes can shift dosing; choose a stable local time and stick with it. A pill organizer and phone reminders can support consistency. Dispose of expired tablets according to local guidance or pharmacy take-back programs.

Benefits

This therapy is non-addictive and does not produce euphoria. By blocking opioid receptors, it may blunt the reinforcing effect of alcohol and prevent opioid-induced effects if opioids are taken. The once-daily oral schedule is straightforward for many treatment plans. Combined with counseling, it can support long-term recovery goals.

Programs can be individualized. Your clinician may coordinate with therapists and peer-support resources to build a plan that fits your needs.

Many patients find it easier to stay engaged in care when education and follow-up are part of the plan. Using reminders and keeping medicines in a visible, secure place can help you stay on track.

Side Effects and Safety

• Nausea or stomach pain
• Headache or dizziness
• Trouble sleeping or fatigue
• Joint or muscle aches
• Decreased appetite

Serious effects are less common but can include liver-related problems. Stop the medicine and seek medical help if you notice unusual fatigue, abdominal pain, dark urine, or yellowing of the skin or eyes. Starting while opioids are in your system can cause sudden withdrawal. Tell clinicians that you take an opioid blocker before any procedure or new prescription.

Drug Interactions and Cautions

Do not use with opioid analgesics, opioid cough syrups, or opioid-containing antidiarrheals. Tell your clinician before surgery; pain control plans may need adjustments. Avoid alcohol-related liver strain and discuss any other liver-impacting medicines. While interactions with many common non-opioid drugs are limited, always review your full medication list, including over-the-counter products and supplements.

People attempting to override the blockade by taking large amounts of opioids are at risk of serious harm, including overdose. After stopping this medicine, reduced tolerance may increase overdose risk if opioids are used. Keep an overdose-response plan accessible. Discuss community access to Narcan® Nasal Spray with your clinician as part of safety planning.

What to Expect Over Time

With consistent use and support, cravings may lessen and lapses can become easier to interrupt. Counseling, peer support, and structured check-ins help reinforce new habits. Many programs start with regular visits and then adjust the schedule as needs evolve.

Recovery often involves changes to routines, environment, and stress management. Keep communication open with your clinician about goals, challenges, and side effects. They may adapt your plan or suggest practical tools to help adherence.

Compare With Alternatives

Generic naltrexone offers the same active ingredient as the brand; check our product page for Naltrexone to review available options. For opioid use disorder, some patients are managed with partial agonist therapy; see Suboxone® for a product used in medication-assisted treatment alongside counseling. Your clinician can explain how these choices differ and which may fit your plan.

Availability and Substitutions

Stock can vary by manufacturer and package size. If a specific brand is unavailable, your prescriber may authorize an equivalent generic. When you compare ReVia online with generic listings, review tablet quantity, manufacturer, and required documentation. If a product is temporarily out of stock, your clinician may suggest a suitable alternative or adjust the fill size. We do not list restock dates.

Patient Suitability and Cost-Saving Tips

Good candidates are adults motivated to reduce or stop alcohol use, or to maintain opioid abstinence after detoxification, with access to counseling. People who currently use opioids or have acute hepatitis or liver failure should not take this medicine. Discuss monitoring if you have liver disease or take other hepatically metabolized drugs.

To manage costs, consider larger fills if appropriate for your plan, schedule refills early, and compare brand versus generic. Set reminders for renewal dates, and ask your clinician about supervised dosing if that reduces visits. You can review Naltrexone without insurance options on the product page and choose the quantity that fits your budget and treatment plan.
