What you should know

Sensitizing (aversive) therapy has been used in addiction medicine since the mid-20th century. Its principle is to create a physiological “barrier” to drinking: the drug blocks the enzyme aldehyde dehydrogenase, so when alcohol is consumed, acetaldehyde builds up in the blood. The resulting symptoms — a feeling of heat, facial flushing, a pounding heart, nausea and a drop in blood pressure — act as a deterrent. The method works best in motivated patients who take it under supervision.

Chemical protection against alcohol in Aksay at Narcology 24 is provided by a psychiatrist-narcologist after an in-person consultation and assessment. The patient receives a detailed explanation of the mechanism, how long it lasts, a list of foods and medications containing alcohol that must be avoided, and the consequences of drinking. The procedure is not performed without written informed consent and the required period of sobriety. Chemical protection is seen as support for the decision not to drink, not as a substitute for treating the dependence.

Who chemical protection may be recommended for

• people with alcohol dependence who have made their own decision to stop drinking
• those for whom an external “safety net” matters in the first months of sobriety
• patients after detox who still have a high risk of relapse
• those for whom psychotherapeutic methods have not worked well enough
• people who have stayed sober for the required period and show no signs of withdrawal
• people with normal ECG, blood pressure and liver function
• those who are ready to attend regular consultations with an addiction physician and a psychotherapist

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 the method works and what its limitations are

Normally, the liver converts alcohol into acetaldehyde and then into harmless acetic acid. A sensitizing drug blocks the second step, so acetaldehyde builds up. The reaction can range from moderate (flushing, a pounding heart, nausea) to severe (a drop in blood pressure, heart rhythm disturbances, seizures). That is exactly why the method requires a cardiovascular assessment and strict sobriety.

International guidelines, including NICE, consider sensitizing drugs an option for patients aiming for complete abstinence, provided there is supervision and no contraindications. The weak point of the method is that its effect depends on adherence: if a person is not committed to sobriety, they may stop treatment or take the risk of drinking. That is why chemical protection works best combined with psychotherapy.
