Revia (Naltrexone) Buyer and Patient Handbook in Malaysia

What is Revia?

Revia is the brand name for the medication Naltrexone, classified as an opioid antagonist. This medication is primarily used in Malaysia as part of comprehensive treatment plans managing Alcohol Dependence and, in some specialized contexts, opioid use disorder. It is available in the standard pill form. Naltrexone works by blocking the euphoric effects of alcohol or opioids, thereby reducing cravings and the likelihood of relapse. It is an approved therapy within national health guidelines for these specific dependencies.

Who Should Use Revia?

Revia (Naltrexone) is appropriate for adults who:

• Are actively seeking to reduce or eliminate their consumption of alcohol.
• Are not currently dependent on opioid medication or are already fully detoxified from opioids.
• Possess a strong commitment to an ongoing maintenance program that includes counseling and support.
• Have completed a full opioid detoxification program before starting Naltrexone therapy.

How Does It Work?

Naltrexone functions by binding to the opioid receptors in the brain, which are the same receptors activated by alcohol or opioid drugs. Effectively, Revia blocks these receptors, preventing mood-altering substances from producing their usual reinforcing effects. Imagine it as putting a lock on a door; when alcohol is consumed, the expected "reward" signal cannot reach the brain’s pleasure centers. This mechanism significantly diminishes the rewarding feeling associated with drinking or using opioids, helping to break the compulsive cycle of addiction. It does not physically prevent someone from consuming alcohol, but it removes the central reinforcement that drives continued use.

Why Choose Revia?

Revia (Naltrexone) offers a pharmacological tool to support psychological counselling efforts. The primary advantage lies in its ability to reduce post-treatment craving intensity, especially for chronic heavy drinkers attempting abstinence. While the active ingredient, Naltrexone, is widely available, choosing a specific formulation like Revia ensures consistent quality control and verifiable product standards recognized within the Malaysian healthcare framework. This medication serves as an adjunct therapy, meaning it works best when used alongside structured behavioural support.

Dosage, Administration, Lifestyle and Dietary Recommendations

Recommended Dosage

The standard initial dose for managing alcohol dependence is 50mg taken once daily. Your healthcare provider will guide the exact titration process, especially if starting doses are lower, though 50mg is the common maintenance level.

How to Take

Take your Revia pill at the same time each day with a full glass of water. You may take it with or without food. Consistency in timing is key to maintaining therapeutic levels in your system.

Missed Dose

If you forget a dose, take it as soon as you remember that day. If it is almost time for your next scheduled dose, skip the missed one entirely. Do not double the dose to catch up.

Overdose

While the acute toxicity of Naltrexone alone is generally low, an overdose situation needs immediate professional attention. If you suspect an overdose, contact emergency services immediately; do not wait for symptoms to worsen.

Special Populations

• Elderly Patients: Dosing generally follows standard adult schedules, but cautious monitoring by a medical professional is advised due to potential changes in metabolism.
• Impaired Liver or Kidney Function: Lower doses may be necessary, or the medication may be contraindicated based on the severity of organ impairment.
• Children: Safety and efficacy in pediatric patients have not been established for the approved indications.

Lifestyle & Diet

It is generally recommended to avoid alcohol completely while taking Revia (Naltrexone), as consuming alcohol while on the drug can lead to severe Nausea or Vomiting, beyond the risk of relapse. There are usually no specific dietary restrictions related to food processing, unlike some other medications.

Precautions and Warnings

Patients must inform their specialist if they are taking any opioid-containing products (including some Cough syrups or Pain medications), as Revia will block their effects, potentially leading to severe opioid withdrawal symptoms. Complete abstinence from opioids must be confirmed before initiating therapy. Monitoring for liver function is generally recommended, particularly at the start of treatment.

Frequently Asked Questions

How long does it take for Revia to start working?

Revia (Naltrexone) begins to exert its effects shortly after the first dose is absorbed, provided the patient has no opioids in their system. Full therapeutic benefit, involving decreased craving intensity, usually becomes apparent over several weeks of consistent daily dosing once steady-state concentrations are achieved in the body.

Can I still drink small amounts of alcohol while on Revia?

While the medication is designed to block the positive effects, consuming alcohol while on Naltrexone is strongly discouraged. If you drink, you risk severe nausea, vomiting, and, more critically, you are failing to maintain the required abstinence that supports long-term recovery.

What happens if I need sudden pain relief from an injury while taking Naltrexone?

You must inform any attending medical personnel that you are taking Revia (Naltrexone). If opioid pain relief is essential, a specialist will need to manage the situation, potentially involving a temporary interruption of Naltrexone under strict supervision, as the opioid drug will be significantly less effective.

Is Revia effective for treating opioid addiction or just alcohol use disorder?

Naltrexone is approved globally for both indications, though its deployment strategy differs. For opioid use disorder, it requires prior complete detoxification; for alcohol, it supports abstinence maintenance by blocking reward pathways.

Does Revia cause weight gain or loss?

Weight fluctuation is not a characteristic, predictable effect of Naltrexone maintenance; however, some individuals report loss of appetite initially, which may lead to temporary weight loss.

If I stop drinking, do I still need to take Revia?

Yes, discontinuation after stopping drinking should only occur in collaboration with your specialist. As long as you remain susceptible to relapse, continuing the medication provides a critical barrier against returning to prior patterns of use.

Can Revia affect my ability to drive or operate machinery?

Some patients report dizziness or drowsiness, especially when starting therapy; exercise caution until you know how Revia impacts you. Avoid high-risk activities if you feel unsteady.

Will my mood be affected by this medication?

Mood changes, including anxiety or depression, can occur; report any significant or worsening mood disturbances immediately to the healthcare team overseeing your treatment.
