The anti-alcohol injection: why it is naltrexone, not disulfiram
Online, the phrase anti-alcohol injection leads to two completely different drugs, and confusing them can put someone off a sensible method or push them toward the wrong one. So before we compare the injection with other options, let us establish its identity. With us the injection is extended-release naltrexone, sold under the name Vivitrol, and not disulfiram, on which the alcohol implant is based.
Naltrexone versus disulfiram: two different injections
Both drugs are sometimes given by injection, but that is where the similarity ends. Disulfiram works through aversion: it couples alcohol with a violent, unpleasant episode, so that the patient refrains from drinking out of fear of the reaction. Naltrexone comes from a different group, the opioid receptor antagonists, and sets no trap in the body. After drinking nothing violent happens, because its role is quieter: it takes part of the reward away from drinking, so that day to day the patient does not feel the drug working at all.
How naltrexone quiets the alcohol craving
The urge to drink grows out of the reward system, which rests on the opioid receptors. Naltrexone covers these receptors, so alcohol no longer sets off the old discharge of pleasure, and each further glass gives less and less. After a few weeks the alcohol craving itself also quiets, that intrusive thought about drinking which is usually harder to bear than the chance of a drink. The drug is not addictive and leaves no symptoms after it is stopped, because it does not stimulate the nervous system, it only dampens it.
Where a single dose's monthly reach comes from
The monthly rhythm comes down to how the preparation is built. The naltrexone is enclosed in microspheres, tiny beads of a soluble polymer, which after injection release the substance slowly, over the following weeks. This does away with swallowing a daily tablet and watching at home whether it has been taken today. A single injection covers a full 4 weeks at once, and the decision to treat does not have to be made anew every morning.
Who qualifies for the injection and what tests come before it
Whichever method the doctor points to, everything begins with qualification. For the injection it weighs more than for a tablet, because giving naltrexone is decided not by the patient's wish or the family's pressure, but by the doctor's assessment. Without it we do not perform the procedure, and for a Gdańsk resident it means one visit to Gdynia.
From the first phone call to qualification
It starts with a single phone call, made just as easily by the patient as by someone from the household. You can come to the qualification alone or with a companion. If someone turns up during a drinking binge or with withdrawal symptoms, the order reverses: first alcohol detox in Gdańsk, and only on a clean body do we carry out the qualification. Naltrexone must not be given to anyone who is in the middle of stopping alcohol.
Opioids: the most important topic of qualification
During the interview the doctor asks about the course of the drinking, earlier treatment attempts, chronic illnesses and a full list of medicines. Mood is examined separately, because its dips more often affect people who drink. Most attention, however, goes to opioids. Naltrexone and opioid drugs cancel each other's action, so the doctor must know every such preparation around the patient, from strong painkillers to substitution treatment. Hiding them is dangerous, not merely an obstacle to setting the dose.
Blood tests before naltrexone is given
To the qualification we add a full set of tests meant to confirm that the drug will harm no one. It includes a complete blood count, a liver panel and tests for hepatitis B, hepatitis C and HIV, and for women of childbearing age also a pregnancy test. We look most closely at the liver, because it is the liver that metabolizes naltrexone, and its severe diseases close the door to the injection. We set the date of the injection only with the full results on the table.
Naltrexone safety: opioids, the liver and contraindications
Naltrexone is a drug with a long history and solid documentation, but it has limits that must be stated plainly at qualification. The patient learns the full list of risks from the doctor before the first injection, not after it.
Loss of opioid tolerance and the risk to life
This warning we discuss the longest, because life is at stake. During treatment the body grows unaccustomed to opioids and becomes far more sensitive to them, and that sensitivity persists for some time after the last injection. Anyone who then tried to break through the blockade with a larger dose, or to go back to the amounts from before treatment, risks respiratory arrest, which can be fatal. The rule is hard: for at least 30 days from the last dose, no opioid drugs at all. It is also worth carrying information that you are taking naltrexone, in case of injury or sudden surgery.
Naltrexone side effects in everyday practice
The bulk of adverse effects are mild and transient: nausea, headache, drowsiness, muscle and joint aches. Around the injection site itself there may be tenderness, hardening or swelling, and quite exceptionally a skin change worth showing to a surgeon. Two things we keep under closer watch. The first is the liver, whose jaundice, dark urine or abdominal pain are a signal to make contact without delay. The second is mood, more often lowered in people with an alcohol problem, so we do not leave it without a question.
Contraindications that rule out the injection
There are also states that close the door to the injection at once. We will not give naltrexone to a person who:
- takes opioid drugs in any form, including substitution therapy and strong painkillers,
- is going through a withdrawal syndrome, that is withdrawal symptoms,
- has acute hepatitis or severe liver failure,
- is pregnant,
- does not tolerate naltrexone itself.
To this is added a borderline situation: a planned operation in which it is hard to manage without an opioid painkiller. That is exactly why qualification and tests are not a box to tick with us, but the moment when such obstacles come to light, before the needle even comes into play.
Where Vivitrol comes from: targeted import, the law and the cost
Good test results open the longest stretch of the road, namely bringing the drug in. With it returns the question of legality, because online there circulates the claim that the anti-alcohol injection is banned in Poland. This is a misunderstanding worth clearing up at the very start.
Targeted import as the legal route for Vivitrol
Vivitrol does not appear in the Polish drug register, but the law keeps a separate side door for such situations. Targeted import (import docelowy) allows the preparation to be brought in by name, for a specific patient, by the same route through which other drugs unregistered here reach Poland. The procedure is strictly laid out: the doctor files an electronic request in the SOID system, a voivodeship or national consultant reviews it, usually within 7 days, and the final approval is issued by the Minister of Health. The basis is a diagnosis of alcohol dependence, so there is no question of the black market, but there is a waiting time.
How Vivitrol is brought in and stored
The minister's approval does not end the matter, because the actual order is placed by a pharmacy, and a wholesaler takes on the transport. A targeted-import prescription is valid for 120 days, so we order ahead, so that no gap opens up between doses. The preparation tolerates heat poorly: it is kept in cold storage, at a temperature of 2 to 8 degrees Celsius, and reaches room temperature only just before the injection. This cold-storage requirement is one of the reasons we give the injection at the office and not in the patient's home.
Reimbursement and the components of the treatment cost
What remains is money. A reimbursement application goes to the Minister of Health and is considered case by case, but for Vivitrol in alcoholism no approval has so far been granted, and in 2022 the AOTMiT Transparency Council judged such reimbursement unjustified. In practice this means the patient pays for the drug, and we say so plainly before we start bringing it in. The cost itself is not a single item, but the sum of several, which we write down after qualification, when setting the date.
Giving the injection, the four-week rhythm and the length of treatment
The day of the injection turns out calmer than the imagination suggests, because it comes down to a single shot. Patients usually ask about three things: how the injection proceeds, how often the dose returns and when treatment can be brought to a close.
How the 380 mg injection is given
The injection itself is short, but one more check comes before it. The doctor makes sure that no opioids have appeared since the previous visit, that there is no jaundice or withdrawal symptoms and that there is no operation with opioid anesthesia in the plans. In parallel, the preparation taken out of cold storage reaches room temperature. Only then do 380 mg travel deep into the gluteal muscle, and at each following visit the side changes. The patient does not have to prepare anything at home or bring anything.
The four-week rhythm: why the dose returns each month
A single dose works for roughly 4 weeks, so the next injections fall once a month. Toward the end of this window the drug begins to weaken, which is a further reason not to push the date back. If an injection is delayed, we give the next one as soon as possible, but no sooner than after 4 weeks and in no dose larger than 380 mg. For a patient from Gdańsk this is one short visit to Gdynia once a month, easy to fit into the calendar.
The length of treatment and what the naltrexone studies say
How long the whole treatment lasts does not fit into a single number. The manufacturer's product information sets no fixed end, scientific societies usually speak of at least six months, and in practice it is decided by maintained abstinence and the response to successive doses. I treat the figures from studies as a reference point, not a declaration of effectiveness. Garbutt's team published a result in the journal JAMA in 2005 in which, at the 380 mg dose, days of heavy drinking were roughly a quarter fewer than after placebo. A newer pooled analysis from 2022, covering seven studies, pointed to greater benefit with treatment longer than three months, with the caveat that observations reached at most half a year. On its own naltrexone gives less than in tandem with therapy.
Access to addiction treatment in Gdańsk and the planned injection path
The naltrexone injection does not work in a vacuum, it plugs into how easily one can reach treatment in a given city. Here Gdańsk shows a clear tension: help for intoxicated people exists, but the planned treatment of alcohol craving that the injection targets can be weeks of waiting away.
How long you wait for addiction treatment in Gdańsk
On the NFZ map Gdańsk fares decently in numbers: addiction-treatment services are provided here by about eight facilities, with several dozen more across the whole Pomeranian voivodeship. It is worse with time. The average wait for a first appointment reaches about 91 days in Gdańsk clinics, though in individual places one manages to get in within a few days. For someone who has just decided to quit drinking, three months in a queue is a real test in which motivation has time to weaken. A planned, private path is not better than the public one as a rule, but it shortens that first, most fragile interval.
Gdańsk: sobering up is not treatment
The emergency side of help in Gdańsk is clearly visible. The former sobering-up station was closed in 2008, and its role was taken over by a municipal social emergency unit for intoxicated persons, through which more than 10,000 admissions pass a year, with a rising trend. It is a needed place, but it deals with the aftermath of a single night, not with addiction. Supervised sobering up can be a rescue, but it moves neither the alcohol craving nor the reward system, so on its own it treats nothing. This gap between sudden intervention and planned treatment is filled precisely by doctor-led therapy with naltrexone.
The injection for Gdańsk residents: the nearest facility in Gdynia
In Gdańsk itself we do not run a physical clinic, so we arrange the qualification, the tests and the injection at our nearest facility, in Gdynia at Franciszka Sokoła 28. From most districts of Gdańsk that is about half an hour's drive, and the Tricity area is in any case tied together by the SKM rail and a few main routes. For the injection this distance happens to matter little: the injections return once every 4 weeks, and the cold storage and office conditions argue anyway for giving the drug on site, not at home. The first phone call handles the whole arrangement, including fitting the dates to the journey from Gdańsk.
Injection, implant or tablets: what suits whom better
Since there are already the alcohol implant and tablets, why would anyone also need the injection? This question comes back in most first conversations. The three methods really do differ, and not in the form of delivery, but in what each of them does with drinking.
Three ideas for one problem: injection, implant, tablets
The disulfiram implant sets up a barrier: after alcohol comes a reaction dangerous enough that the patient does not drink, just to avoid it. The naltrexone injection comes from the opposite side, without aversion. After alcohol it does not cause unpleasant effects, but instead takes the reward away from drinking and slowly extinguishes the craving. The tablets contain the same naltrexone, only in a version for daily, self-administered swallowing. For anyone drawn more to a clear, deterrent boundary, we describe it separately on the page for the alcohol implant in Gdańsk.
When the injection works out better than the implant
The injection shows its greatest value where daily self-discipline is the weakest link. The daily tablet falls out of rhythm exactly when things are hardest, and those moments most often end in relapse. The once-a-month injection removes that daily test of will, because the decision was already made at the time of the injection. The implant, in turn, suits someone who wants a clear barrier right away. The injection, after all, has its weaker point in the calendar: Vivitrol first has to be brought in through targeted import, and that means a few weeks of delay, which the implant does not require.
Why the doctor decides the method at qualification
There is no method best for everyone, there is one best for a particular person. It is settled by the drinking history, coexisting illnesses, the medicines being taken and what the patient fears most. That is why the choice is made at qualification, together with the doctor, and not at the kitchen table or after reading a forum. The family comes off best this way, because no one carries a medical decision solely on their own shoulders.
Booking the injection for Gdańsk, the trip to Gdynia and the role of loved ones
Finally the most down-to-earth matter: where exactly to start. Here Gdańsk differs from the other cities in one detail, the address of the visit. Apart from that everything is simple, because the first move is a single phone call, made just as often by the patient as by someone from the family.
Booking the qualification for a patient from Gdańsk
The number is 880 808 880, and we book the qualification at our nearest facility, in Gdynia at Franciszka Sokoła 28. No referral is needed, just as in an addiction-treatment clinic. Since the drug alone rarely closes the matter, from the first visit we link it with addiction therapy in Gdańsk, and in harder situations with full alcoholism treatment in Gdańsk.
The role of loved ones in injection treatment
Loved ones will not give the drug or go through qualification for the patient, but they take on the hardest part: they help take the first step. You can call for details, come along to the visit in Gdynia, keep an eye on the dates of the next doses. We advise against only one thing, bringing someone against their will. Naltrexone works best when the patient wants to try on their own, and the family's task is to make that decision easier, not to force it.
Why we do not give the price over the phone
We will not throw out a single figure over the phone, because it is made up of several separate items: the consultation, the tests, bringing the drug in through targeted import and the injection itself with the later visits. Which of them turn out to be needed is known only after qualification, so any number given earlier would be guesswork. That is why we present the full quote after the first visit, calmly and in writing.
