FAQ
What Revia strengths and pack sizes can I order?
Revia comes as 50mg naltrexone tablets in packs of 10, 20, 30, 60, 90 or 120. It is generic naltrexone, not the original Revia. Larger packs cost less per tablet.
How is Revia sent to Hong Kong?
Revia tablets can go by tracked courier in 5 to 9 business days with online tracking, or by standard airmail in 14 to 21 business days, untracked. Every order ships in plain, unbranded packaging.
What other names is naltrexone sold under?
Revia is a brand name of naltrexone, which is also sold as Depade, Naltima, Nodict and Vivitrol. Here, naltrexone can be bought online as generic Revia. These are generics, not the original brand.
How long does Revia take to work?
The block on opioid receptors begins within about an hour of a dose, so opioid painkillers stop having their usual effect quickly. The effect on alcohol cravings builds more slowly, over several days of steady dosing. Revia does not make you feel drunk or high, and it does not create a dislike of alcohol.
Can I drink alcohol while taking Revia?
Revia is used by people trying to stop drinking, and it does not make drinking safe. Alcohol still harms the liver and undercuts the treatment. Unlike disulfiram, naltrexone does not make you ill after a drink, and it does not stop you getting drunk.
What happens if I take an opioid painkiller with Revia?
Naltrexone blocks opioid painkillers, so a normal dose may give little or no pain relief. Taking a larger dose to overcome the block is dangerous and can cause serious injury, coma or death. Codeine cough syrups, antidiarrhoeal medicines and street opioids are affected in the same way.
Does Revia stop opioid withdrawal symptoms?
No, and if opioids are still in the body it can bring withdrawal on. Naltrexone is started once the body is clear of opioids. Its job is to help prevent a return to use, not to treat withdrawal.
How long does a 50mg dose of Revia last?
About 24 hours, which is why it is taken once a day. Naltrexone itself leaves the blood within hours, but its main active by-product lasts longer and keeps the block going. A missed day can leave the opioid receptors uncovered again.
About Revia
What Revia is used for
Revia contains naltrexone, an opioid antagonist — a medicine that occupies opioid receptors so opioid drugs cannot work there. It is used alongside counselling or a support group by people who have already stopped drinking alcohol or using opioids. Naltrexone cuts the pull of alcohol and blocks the effects of opioid drugs, so the reward that once came from drinking is largely gone. It does not treat opioid withdrawal or ease its symptoms. Starting the tablets before the body is clear of opioids can trigger withdrawal.
How naltrexone works
The brain's reward pathway runs on mu-opioid receptors, the sites opioid drugs attach to. Naltrexone settles onto those receptors and stays put, so opioid drugs find nothing to bind to and the pleasant signal drinking normally produces is dampened. The block is strongest for opioid medicines: painkillers, codeine cough syrups, antidiarrhoeal medicines and street opioids may have little effect while the tablet is working. Cravings fall away over the first days of daily dosing, not after one tablet.
Taking Revia
Revia is one 50mg tablet a day at about the same time, and food makes no difference. If it turns your stomach, a small snack helps. A forgotten tablet can be taken later the same day, but never two together to catch up. Naltrexone only protects while it is being taken, so courses commonly run for months rather than weeks.
Side effects and interactions
Headaches, nausea, tiredness and trouble sleeping are the ones people report most, sometimes with dizziness and stomach upset; they tend to settle as the body adjusts. A few people notice low mood or anxiety. Liver damage is uncommon but can be serious — dark urine, yellowing of the eyes or skin, or tiredness that will not lift are warning signs. Opioid painkillers may give little relief at their normal dose while naltrexone is working, and taking a bigger dose to get around the block can cause serious injury, coma or death. Codeine cough medicine and loperamide for diarrhoea count as opioids too. Heavy drinking can still push liver enzymes up and works against the goal.
Revia 50mg tablets
What is stocked is generic naltrexone 50mg, not the original branded product, in packs of 10, 20, 30, 60, 90 or 120. A tablet lasts 24 hours, so a pack of 30 covers about a month. The tablets stay in their blister strips until each one is taken.
