ReVia® (naltrexone) Tablets for Alcohol and Opioid Dependence

What ReVia® Is and How It Works

ReVia is the brand name for naltrexone hydrochloride, a prescription opioid receptor antagonist. It helps maintain abstinence in alcohol use disorder and prevents relapse in opioid dependence once detoxified. ReVia 50 mg tablets are taken by mouth, usually once daily. Many people search for revia online to access Canadian pricing and convenient home delivery.

YouDrugstore is a licensed Canadian pharmacy headquartered in Manitoba; prescriptions are reviewed by licensed pharmacists before dispensing.

Naltrexone blocks mu-opioid receptors. By blocking these receptors, it reduces the rewarding effects of alcohol and prevents opioids from producing euphoria or analgesia. ReVia does not treat acute withdrawal and is started only after opioids are cleared. It is non-addictive and does not cause dependence. The medication supports counseling and recovery programs by lowering cravings and removing reinforcement from alcohol and opioids. We partner with licensed, vetted international pharmacies when needed to offer authentic brand medicines, a broad selection, and affordable options.

Dosage and Usage

Follow your prescriber’s directions and the patient leaflet that comes with the product. Typical points from product labeling include:

• Start only after being opioid-free for an adequate period (often 7–10 days) to avoid precipitated withdrawal.
• Alcohol dependence: common maintenance dose is 50 mg by mouth once daily.
• Opioid dependence relapse prevention: common maintenance dose is 50 mg once daily after detoxification and a negative opioid screen.
• Some patients begin with 25 mg (half tablet) as a test dose to check tolerance.
• Take with or without food. Taking with food may reduce nausea.
• Do not use if actively taking opioid pain medicines, methadone, or buprenorphine.
• Carry medical identification stating naltrexone use; standard opioid pain medicines may not work in emergencies.
• Missed dose: take when remembered unless it is close to the next dose; then skip. Do not double.

Storage and travel tips:

• Store at 20–25 °C (68–77 °F); short excursions 15–30 °C (59–86 °F).
• Keep tablets in the original, tightly closed bottle to protect from moisture.
• Do not use after the expiry date. Check the bottle seal before first use.
• Pack your supply in carry-on when flying, with a copy of your prescription.
• Avoid heat, direct sunlight, and bathroom humidity.
• If a tablet chips or crumbles, discard it and use a new tablet.

Benefits and Savings

ReVia helps reduce alcohol cravings and the urge to drink. In opioid dependence, it blocks the effects of opioids, supporting abstinence after detox. It is non-sedating and non-habit forming, and once-daily dosing fits well into treatment plans. When combined with counseling and support programs, many patients maintain longer periods of sobriety.

Ordering ReVia online from Canada can lower costs significantly. Customers often see 60–80% savings versus typical US prices, especially with multi-month supplies. Ask your prescriber if a generic revia option (naltrexone HCl) is suitable to reduce the cost of revia further. To check seasonal offers, see our revia coupon.

Side Effects and Safety

• Nausea, vomiting, or abdominal pain
• Headache or dizziness
• Tiredness, insomnia, or anxiety
• Decreased appetite or weight loss
• Joint or muscle aches
• Rash or increased sweating
• Diarrhea or constipation

Serious but less common risks include liver injury (hepatitis), especially at high doses, with symptoms such as dark urine, jaundice, persistent nausea, or right-upper-quadrant pain. Seek urgent help for signs of severe allergic reaction, severe mood changes, or thoughts of self-harm. Do not use ReVia if you are taking opioids, are physically dependent on opioids, have acute hepatitis or liver failure, or if you fail an opioid challenge/urine screen.

Onset Time

Opioid receptor blockade begins within about 1–2 hours of a dose and typically lasts 24 hours with 50 mg. For alcohol use disorder, reductions in craving and heavy-drinking days may emerge in the first 1–2 weeks and continue to improve with adherence over several weeks. Consistent daily dosing and engagement in counseling often correlate with better outcomes.

Compare With Alternatives

Acamprosate (Campral) supports abstinence in alcohol dependence by modulating glutamate and GABA signaling. It is taken three times daily and is not metabolized by the liver, which may benefit those with hepatic concerns. Choice between acamprosate and ReVia depends on drinking patterns, liver status, and adherence needs.

Disulfiram (Antabuse) works as an aversive agent by causing unpleasant reactions when alcohol is consumed. It can be effective for highly motivated patients but requires strict avoidance of all alcohol-containing products. ReVia, in contrast, reduces cravings and reinforcement rather than creating aversion.

For opioid use disorder, agonist therapies such as methadone or buprenorphine-naloxone provide receptor activation to control withdrawal and cravings. ReVia offers an antagonist approach for patients who have completed detox and aim to remain opioid-free.

Combination Therapy

• Behavioral counseling and motivational enhancement alongside ReVia.
• Mutual-support groups or structured therapy programs.
• Treat coexisting depression, anxiety, or sleep issues as indicated.
• Coordinate care if pain management is required; non-opioid strategies are preferred.
• Avoid concurrent opioid medications; emergency pain plans should be documented.

Patient Suitability and Cost-Saving Tips

ReVia is intended for adults with alcohol use disorder or those aiming to prevent opioid relapse after detoxification. It is not for individuals currently using opioids or those with opioid dependence who have not completed withdrawal. A negative opioid screen and, when used, an opioid challenge test help confirm readiness to start therapy.

ReVia may not be appropriate in acute hepatitis or liver failure. Caution is advised with other hepatotoxic medicines and in chronic liver disease. Discuss pregnancy, breastfeeding, and fertility plans with a clinician. People who require opioid analgesia for chronic conditions are not candidates for naltrexone; alternative treatments may be considered.

You can order ReVia with a revia prescription from your provider. Choose the brand or naltrexone eqv revia generic to match your needs. Multi-month supplies can lower the revia pill cost on a per-month basis, and periodic bulk promotions may be available. Set simple reorder reminders so you do not run out. If the revia tablet cost is a concern, ask about generic revia or naltrexone hcl revia options.
