What you should know
Chemical protection is often confused with the “torpedo” from friends’ stories and imagined as a shot after which “you can’t drink or you’ll die.” On house calls, I usually go through these ideas point by point. Yes, it is a medication-based method — one of the forms of alcohol “coding” (a treatment widely used in Kazakhstan and CIS countries) — and yes, alcohol is dangerous while it is in effect. But the goal is not to frighten the person but to give them support for the first months of sobriety while they learn to live in a new way and restore their health.
A typical story goes like this. A night call to the Turksib district, getting out of a binge, a repeat IV drip the next day. A few days later, a consultation at the clinic, where the person comes alone or with his wife, sometimes from Konaev, leaving early to avoid the traffic on the way into the city. The addiction doctor confirms the period of sobriety, checks blood pressure, the ECG and blood tests, discusses the medication and only after the consent form is signed gives the injection.
Who Chemical Protection May Be Right For
- the person wants to stop drinking themselves and is ready to accept a restriction for a set period
- after getting out of a binge, there have already been quick relapses in the first weeks of sobriety
- the person has been steadily sober for several days and withdrawal has passed
- the examination shows no serious heart, liver or kidney disease
- the person values “external” support without surgery and without daily pills
- the person is ready to see a psychotherapist at the same time
- loved ones support the decision and understand how to act going forward
If heavy drinking has lasted more than two or three days, or there is shaking, vomiting, blood-pressure spikes or insomnia, you need a doctor rather than stopping alone. Phone advice is free. For seizures, confusion or hallucinations call 103 or 112.
How Chemical Protection Works and What Its Limitations Are
Chemical protection medications work in two main ways. Some disrupt the normal breakdown of alcohol in the liver: when a person drinks, toxic products build up, causing facial flushing, a pounding heart, nausea and a drop in blood pressure. Others — opioid receptor antagonists — reduce the “reward” from alcohol and cravings for it. International guidelines, including NICE, consider medication-based relapse-prevention therapy part of treatment, in combination with psychosocial support.
The limitations need to be understood in advance. Chemical protection does not treat the reasons for drinking and does not change a person’s lifestyle; it creates a pause. Its effectiveness depends largely on motivation: if the person agrees “for the sake of his wife,” the risk of trying to “test it” is higher. And such tests are dangerous to health. That is why we always combine chemical protection with psychotherapist consultations, work with the family and follow-up by an addiction doctor.
How Chemical Protection Works: From Consultation to Follow-Up
We start with a video consultation or an in-person appointment: the addiction doctor learns about the history of drinking, previous methods, chronic illnesses and medications. Then the period of sobriety is confirmed and an examination is carried out, with an ECG and blood tests as indicated. The doctor explains the medication, how it works, its duration and possible reactions, after which an informed consent form is signed. The injection is given intravenously or intramuscularly, followed by 20–30 minutes of observation and an agreement on follow-up appointments.
Chemical protection is not given if the person is intoxicated or has not been sober long enough, or with serious heart and vascular disease, significant liver and kidney damage, a number of mental and neurological disorders, pregnancy, an allergy to the medication, or without the person’s consent. If someone drinks alcohol while chemical protection is active and feels unwell — a pounding heart, shortness of breath, a drop in blood pressure — call 103 or 112 immediately.
How we help
Preparation and examination
Before the procedure, the doctor assesses the person’s health: blood pressure, pulse, heart rhythm and, if necessary, an ECG and blood chemistry. It is important to rule out contraindications and make sure the person is sober. If they had a drink recently, we postpone the procedure — safety matters more than speed. Sometimes, based on the examination, the doctor suggests a different method or oral medication.
Intravenous chemical protection
The medication is injected slowly into a vein under a doctor’s supervision. Before this, the time of the last drink is checked once more. The advantage of the intravenous route is that the doctor sees the reaction immediately and can respond in time. After the injection, the person rests under observation and then receives a detailed leaflet about how the medication works and what is prohibited.
Intramuscular chemical protection
For some medications, the intramuscular route is preferable — for example, for long-acting forms based on opioid receptor antagonists. This option does not require taking pills every day and suits people who find it hard to stick to a schedule. The choice of form and duration depends on the person’s health and the decision they make together with the doctor.
Support while it is in effect
We offer regular sessions with a psychotherapist, follow-up by an addiction doctor and support for the family. We discuss difficult situations: holidays, corporate parties, stress at work. If a strong craving appears, it is important to call rather than “test” the medication. Toward the end of the period, we plan how to stay sober going forward and decide whether to extend it.
Myths and facts
MythChemical protection is the same as an implant
FactBoth procedures are medication-based methods, but they differ in how the drug is given. Chemical protection is an injection, with no incision or implant; an implant means placing the medication under the skin. The choice depends on the person’s health, the medication and convenience, and it is made by the doctor together with the patient.
MythYou can “test” chemical protection with one shot of vodka
FactSuch “tests” are dangerous: the reaction can be severe even from a small amount of alcohol, including alcohol hidden in medications, sauces or kvass. If you feel the urge to test it, that is a reason to talk to a doctor or psychotherapist.
MythAfter the period ends, you can drink “in moderation”
FactFor a person with an addiction, returning to “moderate” drinking often quickly leads back to the old binges. That is why the end of the chemical protection period is a reason to discuss further support for sobriety with the doctor, not a date when drinking is “allowed.”

Questions and answers
How long do you need to stay sober before chemical protection?
The minimum period of sobriety depends on the medication and the person’s health, and the doctor will tell you what it is. Usually several days of complete abstinence from alcohol are required, sometimes more. If the person is coming out of a long binge, they first need to get through withdrawal with IV drips and only then plan the procedure.
How long does chemical protection last?
The duration is set individually: from several months or longer, depending on the medication, the person’s health and their goals. People often start with a shorter period and then extend it. What matters more than the number itself is how this time is used — for psychotherapy, recovery and new habits.
Can chemical protection be given at home?
A Narcology 24 doctor can carry out some procedures at home after an in-person examination and if there are no contraindications, for example in the Alatau district or Talgar. But if an ECG and blood tests are needed or there are concerns about the person’s health, it is better to have the procedure at the clinic, where everything needed to provide help is at hand.
Which foods and medications must be avoided while chemical protection is active?
Nothing that contains alcohol is allowed: drinks, kefir and kvass that have fermented for a long time, some sauces, alcohol-based tinctures and a number of medications, and mouthwashes. The doctor gives you a detailed leaflet after the procedure, and if you have any doubts, it is best to check with us by phone.
What should we do if the person drinks anyway?
If a pounding heart, shortness of breath, flushing, dizziness, vomiting or chest pain appear, call 103 or 112 immediately and say that chemical protection has been given. If the symptoms are mild, contact the doctor anyway: they will assess the situation and tell you what to do next.
Is it anonymous?
Yes. Chemical protection is provided anonymously, on a paid basis, without state dispensary registration. Information is protected by medical confidentiality under the Code of the Republic of Kazakhstan “On Public Health and the Healthcare System,” and disclosure is possible only in cases expressly provided for by law.
