What happens if you drink a glass or two of alcohol after taking an antibiotic tablet?When can you drink alcohol, how many hours or days after antibiotics can you drink alcohol so as not to harm your health?
Antibiotic and alcohol
A mandatory consequence of the use of alcohol and antibiotics is the reduction of the effectiveness of the treatment.When you drink alcoholic beverages, inflammatory processes develop in the intestines and local immunity decreases.
At the same time, the antibiotic-related bowel disorder is added, which is provoked by taking the antibiotic.
Violation of drug concentration
The antibiotic begins to work after reaching a sufficiently high therapeutic concentration in the blood.Due to the consumption of alcoholic beverages, the amount of the drug in the body decreases.
This type of treatment, when they try to take antibiotics after alcohol, can be considered pointless and even dangerous.
Violation of the treatment regimen, a decrease in the concentration of the drug, increases the resistance of pathogenic microflora to the action of the antibiotic.And the disease itself, against which an antibiotic is prescribed, has a chance to go from acute to chronic.
The concentration of the drug decreases due to the fact that the nephrotoxic metabolite of ethyl alcohol, acetaldehyde, disrupts the process of reabsorption of nutrients in the renal tubules.
Water reabsorption is also impaired, which increases blood viscosity, and the concentration of the antibiotic in the blood can change in the most unpredictable way.
Characteristics of metabolism
Antibiotics are drugs that are metabolized in the liver.Busy with the processing of ethyl alcohol, the liver does not have time to neutralize all possible intermediate metabolic products of the drug.
In addition, ethanol can affect the activity of liver enzymes and even react directly with the antibiotic or its metabolites.These properties are expressed differently in antibacterial drugs.
One of the most dangerous features of combining a drug with ethyl alcohol is the interaction of these chemical compounds with the development of a disulfiram-like reaction.
Let's understand whether it is possible to drink alcohol, beer, while taking antibiotics, after which it is not dangerous to drink alcohol, and after which it is absolutely prohibited.
Disulfiram-like reaction
The disulfiram reaction is used to code alcoholism, accompanied by nausea, cramps, cough, vomiting, shortness of breath and a drop in blood pressure.
A similar effect occurs quite often when taking medications with ethanol.
Below is a list of antibiotics after taking and how long you should not drink alcohol.
The consequences of ethanol intake during antibiotic treatment are dose-dependent.
When you can drink alcohol after taking antibiotics tablets or injections is calculated based on the time it takes for the antibiotic to be eliminated from the body.
List of antibiotics
Do not drink alcohol:
- nitroimidazoles - do not combine with alcohol for up to 48 hours (the drugs give a reaction similar to disulfiram);
- cephalosporins - the chemical structure of this group resembles the disulfiram molecule in structure, which gives a disulfiram-like reaction with ethyl alcohol.You can drink alcohol every other day;in case of kidney failure, the interval is extended;
- fluoroquinolones - synthetic antibiotics suppress the nervous system and can cause coma.Take alcohol no earlier than after 1.5 days;
- tetracyclines - a high risk of damage to liver hepatocytes;they are eliminated from the body for a long time.You can drink alcohol after 3 days;
- aminoglycosides are ototoxic, nephrotoxic, the side effects of the drug increase and the toxicity of the drugs increases.Drink alcohol no earlier than after 0.5 months;
- lincosamides - the central nervous system and the liver are affected, a disulfiram reaction develops.You can drink alcohol 4 days after treatment;
- macrolides - the risk of liver cirrhosis increases, especially when you take erythromycin, they are slowly eliminated from the body.Alcohol is allowed after 3.5 days;
- anti-tuberculosis drugs - can cause drug-induced hepatitis with a vulminative course.Alcoholic drinks are prohibited!
The rate of elimination of antibacterial drugs from different body environments varies.So, if aminoglycosides are eliminated from the blood of adults in an average of 2.5 hours, then from the inner ear fluid this time can be up to 350 hours.
If we consider the ototoxicity of aminoglycosides, it is easy to understand that drinking alcohol within 2 weeks after treatment can cause deafness.
Interaction
A reaction similar to disulfiram during treatment with antibiotics and alcohol consumption develops due to blocking the synthesis of enzymes that destroy the ethanol molecule into simple substances.
The consequence is an increase in the blood concentration of the intermediate product of the breakdown of ethyl alcohol - acetaldehyde.Ethanol's metabolite acetaldehyde is more toxic than ethyl alcohol itself.
And the lack of liver enzymes, as a result of a toxic effect on the liver, causes a decrease in the synthesis of norepinephrine, which is why the symptoms of intoxication the next morning seem brighter and are more difficult to tolerate.
The consequences
The combination of small doses of alcohol and medication may not cause any symptoms, but when you drink large doses of alcohol, the side effects of both the medication and the alcohol increase.
One of the most dangerous consequences of combining alcohol with an antibiotic is a disulfiram-like reaction.The danger of this condition is that it is masked by alcohol intoxication and is not recognized by others as a distress signal.
The disulfiram reaction is caused by an increase in the concentration of acetaldehyde in the blood and is manifested by the following symptoms:
- heartbeat;
- nausea, vomiting;
- hot flush, feeling of heat;
- dizziness;
- abdominal pain;
- a sharp drop in pressure.
If the patient's blood alcohol level is above 125 mg/100 ml and the victim is not given help in time, then death is also possible.
How to combine
Certain medicines should absolutely not be combined with ethyl alcohol in any dose:
- nitroimidazoles;
- group of cephalosporins;
- fluoroquinolones;
- aminoglycosides.
How many days after antibiotics can you drink alcohol?Is it possible to interrupt the course of treatment for a while?
It is best not to combine antibiotics and alcohol at all and not to take ethanol during treatment.If for some reason this is not possible and you have to drink alcohol, then you can calculate how long after drinking an antibiotic you can use a special alcohol calculator.
The alcohol calculator takes into account the person's weight, the amount and strength of the drink taken.Thus, in men weighing 70 kg, 100 g of vodka will be completely eliminated from the body in 5.8 hours, and 200 g of beer - in 1.44 hours.
It should be borne in mind that all these calculations are approximate and the actual rate of elimination from the body depends not only on the properties of these chemical compounds, but also on the condition of the kidneys, intestines and liver.
CONCLUSION
For the complete removal of the antibacterial drug from the body, it should take from 1 to 3.5 - 5 days.The elimination time depends on the health status, age and metabolic characteristics of the person.
In most cases, drinking alcohol while taking a course of antibiotics weakens the effectiveness of the treatment, increases the side effects of the drug, provokes a disulfiram-like reaction and is fraught with serious consequences.
