What the anti-alcohol injection is and how naltrexone works
"Anti-alcohol injection" is the everyday name for an injection of extended-release naltrexone (the Vivitrol preparation). A single dose is 380 mg of the drug in the form of microspheres, which the doctor gives intramuscularly, and the substance is released gradually over about 4 weeks. It is not a vaccine or an "implant", and it does not work by punishing the body for alcohol.
How naltrexone quiets the alcohol craving
Naltrexone blocks the opioid receptors in the brain. It is through them that alcohol switches on the part of the reward system that gives the sense of relief and pleasure after drinking. When the receptors are occupied by the drug, drinking stops producing its former effect, and the nagging urge to reach for another glass fades. At the same time, alcohol brings on no violent, unpleasant physical symptoms, because the mechanism is different from that of aversive preparations.
The anti-alcohol injection versus the disulfiram implant
When someone in Gorzów Wielkopolski hears "an injection for alcohol", they usually picture the implant. These are two different drugs. The implant contains disulfiram and, after drinking, triggers a sharp reaction, so it works by deterrence. Naltrexone in the injection triggers no such reaction; instead it takes the reward out of drinking and helps you hold on from one temptation to the next. We expand on the differences in the comparison section and on the page about the alcohol implant in Gorzów Wielkopolski.
Qualification and tests before the anti-alcohol injection
We start with a qualifying visit, because naltrexone is not a drug for everyone, and the decision to use it rests with the doctor. In the conversation we ask about the history of drinking, earlier attempts at treatment, chronic illnesses and every medicine being taken. This part is not a formality: it decides whether the injection will be safe for a given person.
Why the doctor asks about opioid medicines
The most important issue here is opioids. Naltrexone blocks the opioid receptors, so in someone who has recently taken opioid painkillers or substances from this group, giving the injection may trigger a sudden withdrawal syndrome. That is why we ask about it directly and set an appropriate interval; its length depends on the kind of agent taken and is determined by the doctor.
Which tests we order before the anti-alcohol injection
Before the first dose we order a complete blood count and a liver panel, and where needed tests for hepatitis B and C and HIV. For women of childbearing age we do a pregnancy test. The results show, among other things, how the liver is working, which matters because it is the liver that handles the drug's metabolism. If someone is in active withdrawal and has symptoms of an abstinence syndrome, we first refer them for detox in Gorzów Wielkopolski, and plan the injection for later.
Safety and contraindications for naltrexone
Naltrexone is well studied, but like any drug it has situations in which it must not be given, and others that call for caution. That is why treatment is run by a doctor and does not end with a single injection.
When the anti-alcohol injection cannot be given
We do not give the injection to someone dependent on opioids or taking them on a permanent basis, during an acute withdrawal syndrome, and also with acute inflammation or failure of the liver, or with hypersensitivity to the ingredients of the preparation. Some of these contraindications are established precisely on the basis of the history and the tests described above.
Lowered opioid tolerance after treatment with naltrexone
One thing has to be said plainly, because it concerns health and life. During treatment and for some time afterwards, the body loses its former tolerance to opioids. Going back to the doses taken earlier, for example strong painkillers, can then end in dangerous, even fatal, suppression of breathing. After the last dose, the opioid-free interval is counted in weeks (at least about 30 days), and every change to pain treatment must be discussed with the doctor.
What we watch for between successive doses
At every visit we ask about wellbeing, tolerance of the drug and any adverse effects, most often mild ones such as nausea or tenderness at the injection site. If anything raises doubt, we adjust the plan. The injection is one element of broader treatment, which is why in parallel we offer addiction therapy in Gorzów Wielkopolski.
Targeted import, administration and the every-4-weeks rhythm
Vivitrol is not registered in Poland, so it is brought in lawfully through targeted import (import docelowy). It sounds like a matter of paperwork, but in practice we guide the patient through each step, so that nobody has to handle them alone.
What targeted import of naltrexone looks like step by step
The doctor files an electronic request, a consultant confirms it within 7 days, and the Ministry of Health usually reviews the application within 21 days. Once the drug reaches the pharmacy, we set a date for administration. This is extra time, which is why it is worth planning the first visit and the tests well in advance.
How the injection is given
The administration itself is short. The drug, in the form of 380 mg of microspheres, is injected deep into the gluteal muscle, alternating one side and then the other. Only medical staff do this; naltrexone in this form is not given intravenously or subcutaneously.
The rhythm of treatment and its duration
Successive doses are repeated every 4 weeks, roughly once a month. How long the whole treatment lasts depends on its course; the guidelines usually speak of at least several months, and the decision to continue is made on the basis of the results. The question of possible reimbursement can be raised individually, because it requires a separate application and a decision of the Ministry of Health.
The effectiveness of the naltrexone injection in studies
We talk about naltrexone's effectiveness in figures from studies, not in promises. That lets you soberly judge what can be expected and what cannot.
What the studies on naltrexone depot showed
In Garbutt's randomized trial from 2005, covering 627 people, the 380 mg dose was linked with about a 25 percent drop in the number of heavy-drinking days compared with placebo. A later meta-analysis from 2022, combining seven studies, confirmed fewer drinking days with naltrexone, with a clearer effect over longer treatment, though the data reached only about half a year.
Why the injection is support, not a guarantee
These figures are real help, not a miracle cure. Naltrexone reduces the craving and the risk of returning to heavy drinking, but it does not replace the decision to change and the work on habits. That is why we treat it as part of treatment, alongside therapy and the support of loved ones, and not as a stand-alone answer to addiction.
Risky drinking in Gorzów Wielkopolski and the limits of prevention
Every few years Gorzów Wielkopolski commissions a local social survey, an anonymous questionnaire among residents. The most recent one covered 500 adults and shows well why common sense and bans alone are sometimes not enough.
What the Gorzów survey says about drinking
The survey shows that 6% of respondents reach for alcohol every day, and another 10% drink several times a week; the authors of the survey estimate that risky drinking may affect close to one in six adult residents. Nearly one in three of those who drink take five or more portions on a single occasion. Drinking is sometimes woven into everyday life: 25% of those surveyed admitted that they had sometimes worked under the influence of alcohol, and among drivers who drink, 12% had driven a car after drinking. Many started early, as 44% had their first glass between the ages of 16 and 18.
Why limiting availability does not treat the addiction
The city responds to these figures with, among other measures, a night-time ban on the sale of alcohol in shops. Such steps can cut immediate harm and night-time interventions, but they do not reach the addiction itself, that is, the craving and the mechanism of relapse. This shows in the figures of the municipal commission too: the number of applications sent to the court for an order to undergo treatment fell from 87 in 2019 to 10 in 2021, even though the scale of the problem did not change. The compulsory route is narrow and comes too late. The naltrexone injection is a different path, earlier and voluntary, one that works at the level of the mechanism of drinking, not only its effects.
Where in Gorzów Wielkopolski we give the injection
Qualification and administration take place at our office at ul. Romualda Traugutta 6. Booking a visit and questions about availability are easiest to handle by phone.
Injection, implant or tablets: how to choose a method
The people who come to us in Gorzów Wielkopolski often compare three options: the naltrexone injection, the implant and tablets. There is no single best method; the right one depends on the particular situation.
- The naltrexone injection works every 4 weeks, reduces the alcohol craving and does not require remembering to take a medication every day.
- The disulfiram implant works by aversion: after drinking it triggers an unpleasant reaction, so it rests on deterrence rather than on quieting the craving.
- Naltrexone tablets have a mechanism similar to the injection, but they have to be taken every day, which can be harder to keep up.
Whom the injection suits best
The injection can be a good choice for people who want one decision a month instead of a daily struggle with themselves, and who want to cut down on drinking without frightening the body. The final choice of method comes out of the qualification anyway. If someone is considering an aversive solution, we describe it on the page about the alcohol implant in Gorzów Wielkopolski.
The cost of the anti-alcohol injection and booking a visit
We do not give a price up front, because the cost is made up of several elements, and their scope depends on the particular situation.
What the cost of injection treatment depends on
The cost is made up of bringing the drug in through targeted import (import docelowy), the qualifying visit with tests and the administration itself. We set the exact terms individually when you contact us, before anyone decides on treatment, so that there are no surprises.
