Description of the drug approved by the manufacturer for the printed edition of 2017.


Combined drug for symptomatic treatment of colds and other infectious and inflammatory diseases.

Paracetamol has an antipyretic, analgesic effect.
Paracetamol content in the preparation corresponds to the maximum single dose permitted for over-the-counter use.
Phenylephrine is a vasoconstrictor, relieves nasal congestion (narrows the vessels of the nasal mucosa and paranasal sinuses) and facilitates breathing.

Ascorbic acid replenishes the increased need for vitamin C for colds and flu.

Active components of the drug do not cause drowsiness.



Quickly and almost completely absorbed from the digestive tract, distribution in body fluids is relatively even.

Metabolized mainly in the liver with the formation of several metabolites.

T 1/2 when taking a therapeutic dose is 2-3 hours. The main amount of the drug is excreted after conjugation in the liver.
In unchanged form, not more than 3% of the received dose of paracetamol is released.

It is poorly absorbed from the digestive tract and metabolized by the "first passage" in the intestine and liver under the influence of MAO.
When taking phenylephrine inside the bioavailability of the drug is limited.
It is excreted in urine almost completely in the form of a sulfuric acid conjugate.

Ascorbic acid

Well absorbed from the digestive tract, binding to plasma proteins - 25%.
Distribution in the tissues of the body is wide.
Metabolized in the liver, excreted in the urine in the form of oxalate and unchanged.

Ascorbic acid, taken in excessive amounts, is quickly excreted unchanged in urine.


Elimination of cold and flu symptoms:

increased fever;

- headache;

- chills;

- pain in the joints and muscles;

- stuffiness of the nose;

- Sore throat;

pain in the sinuses of the nose.


Adults are recommended to take 1 packet every 4-6 hours, but not more than 4 sachets within 24 hours. The interval between meals should be at least 4 hours.

Contraindications: severe liver disease.


Contraindication: children and adolescence under 18 years.


The patient should be informed that if the symptoms persist after 5 days of use, stop taking it and consult a doctor.

The drug should be taken only at recommended doses.

The drug should not be taken concurrently with other drugs containing paracetamol, as well as other non-narcotic analgesics (metamizole sodium), NSAIDs (acetylsalicylic acid, ibuprofen), barbiturates, anticonvulsants, rifampicin and chloramphenicol, sympathomimetics (such as decongestants, appetite suppressants , amphetamine-like psychostimulants), with other drugs to relieve the symptoms of colds and flu.

When analyzing the determination of uric acid and
blood glucose level, the patient should inform the doctor about the use of the drug Koldreks В® MaxGrip, tk. the drug may distort the results of laboratory tests evaluating the concentration of glucose and uric acid.
Before taking the drug Coldrex В® MaxGripp need a doctor's consultation in the case of:

- taking metoclopramide, domperidone (used to eliminate nausea and vomiting), or colestyramine, used to lower the concentration of cholesterol in the blood;

- taking medications to reduce blood clotting (for example, warfarin);

- Compliance with a diet with a reduced sodium content - each packet contains 0.12 g of sodium;

-higher infectious diseases (including sepsis) in patients with glutathione deficiency, because they are not affected by the disease.
against the background of paracetamol, the risk of metabolic acidosis may increase, the signs of which are a violation of the frequency and depth of breathing, accompanied by a feeling of shortness of breath (shortness of breath), nausea, vomiting, loss of appetite. If the patient finds these, you should immediately consult a doctor.
To avoid toxic damage to the liver, paracetamol should not be combined with the intake of alcoholic beverages, and should also be taken by persons who are chronically consuming alcohol.

Impact on the ability to drive vehicles and mechanisms

When taken in recommended doses, the drug does not affect the ability to drive vehicles and mechanisms, as well as engage in other potentially hazardous activities that require concentration and speed of psychomotor reactions.
When dizziness occurs, it is not recommended to drive vehicles or work with mechanisms.

In the case of an overdose of Calderx В® MaxGrip (even with good health), the risk of delayed signs of severe liver damage should be considered.

Overdose is caused, as a rule, by paracetamol .
Is liver damage in adults possible with admission? 10 g of paracetamol.
5 g of paracetamol can lead to liver damage in patients who have the following risk factors:
-continuous treatment with carbamazepine, phenobarbital, phenytoin, primidone, rifampicin, preparations of St. John's wort penetrated, or other drugs that stimulate liver enzymes;

-regular consumption of alcohol in excess quantities;

glutathione deficiency (due to malnutrition, cystic fibrosis, HIV infection, starvation, exhaustion).

Symptoms (due to paracetamol): in
within 24 hours, the pallor of the skin, nausea, vomiting, anorexia, abdominal pain; for 12-48 h may show signs of impaired liver function, signs of a violation of glucose metabolism and metabolic acidosis. In case of severe poisoning, severe hepatic insufficiency may develop, including hepatic encephalopathy, coma, and death. Acute renal failure with acute tubular necrosis, which is diagnosed by severe pain in the lumbar region, hematuria and proteinuria, can develop without a severe liver dysfunction. There are reports of cases of cardiac arrhythmias and pancreatitis in case of an overdose of paracetamol.
In the early period, the symptomatology can be limited only by nausea and vomiting and may not reflect the severity of the overdose or the risk of injury to the internal organs.

Treatment: during the first hour after the alleged overdose, it is advisable to administer the activated carbon inside.
After 4 or more hours after the alleged overdose, a determination of the paracetamol concentration in the plasma is required (an earlier determination of the paracetamol concentration may be unreliable). The antidote is acetylcysteine. Treatment with acetylcysteine ​​can be performed up to 24 hours after taking paracetamol, but the maximum hepatoprotective effect can be obtained in the first 8 hours after an overdose. After that, the effectiveness of the antidote drops sharply. If necessary, acetylcysteine ​​can be administered iv. In the absence of vomiting, an alternative option (in the absence of the possibility of rapid receipt of inpatient care) is the appointment of methionine inside. Treatment of patients with severe impairment of liver function 24 hours after taking paracetamol should be done in conjunction with specialists from a toxicological center or specialized department of liver diseases.
At the first signs of an overdose, it is necessary to immediately seek medical help, even if there are no distinct symptoms of poisoning.

Symptoms caused by phenylephrine : irritability, headache, dizziness, insomnia, increased blood pressure, nausea, vomiting, increased excitability, reflex bradycardia.
In severe cases of overdose, it is possible to develop hallucinations, confusion, seizures, arrhythmias. An overdose of phenylephrine can cause symptoms similar to side effects.
Treatment: symptomatic therapy, with severe arterial hypertension, the use of alpha-blockers, such as phentolamine.

Symptoms caused by ascorbic acid :
when using more than 1 g - headache, increased excitability of the central nervous system, insomnia, nausea, vomiting, diarrhea, hyperacid gastritis, damage to the mucous membrane of the gastrointestinal tract, suppression of the function of the insulin pancreas apparatus (hyperglycemia, glucosuria), hyperoxaluria, nephrolithiasis (calcium oxalate) damage to the glomerular apparatus of the kidneys, a decrease in the permeability of capillaries (possibly deterioration of tissue trophism, increased blood pressure, hypercoagulability, development of microangiopathies).
Ascorbic acid in high doses (more than 3000 mg) can cause temporary osmotic diarrhea and gastrointestinal disturbances, such as nausea, discomfort in the stomach.

Manifestations of an overdose of ascorbic acid can be categorized as those that are caused by severe liver damage as a result of an overdose of paracetamol.

Treatment: symptomatic, forced diuresis.


Paracetamol, when taken for a long time, increases the effect of indirect anticoagulants (warfarin and other coumarins), which increases the risk of bleeding.
Episodic intake of a single dose of the drug has no significant effect on the effect of indirect anticoagulants.
Inducers of microsomal oxidation enzymes in the liver (barbiturates, diphenin, carbamazepine, rifampicin, zidovudine, phenytoin, ethanol, flumecinol, phenylbutazone and tricyclic antidepressants) increase the risk of hepatotoxic effects in overdoses and simultaneous administration with paracetamol.

Inhibitors of microsomal oxidation (cimetidine) reduce the risk of hepatotoxic effects.

Paracetamol decreases the effectiveness of diuretic drugs.

Metoclopramide and domperidone are increased, and colestramine reduces the rate of absorption of paracetamol.

Paracetamol increases the effects of MAO inhibitors, sedatives, ethanol.

Phenylephrine when taken with MAO inhibitors may lead to an increase in blood pressure.

Phenylephrine reduces the effectiveness of beta-adrenoblockers and antihypertensive drugs, increases the risk of hypertension and cardiovascular disorders.

Simultaneous use of phenylephrine with sympathomimetic amines can increase the risk of side effects from the cardiovascular system.

Tricyclic antidepressants increase the sympathomimetic effect of phenylephrine, and may increase the risk of developing side effects from the cardiovascular system.

The simultaneous use of halothane with phenylephrine increases the risk of ventricular arrhythmia.

Phenylephrine reduces the hypotensive effect of guanethidine, which, in turn, enhances the alpha-adrenostimulating activity of phenylephrine.

Antidepressants, antiparkinsonics, antipsychotics, phenothiazine derivatives increase the risk of urinary retention, dry mouth, constipation.

Simultaneous administration of GCS with phenylephrine increases the risk of developing glaucoma.

When used simultaneously with digoxin and cardiac glycosides, there may be an increased risk of heart rhythm disturbances or heart attack.

Ascorbic acid increases the risk of developing crystalluria in the treatment of short-acting salicylates and sulfonamides, slows the excretion of acids by the kidneys, increases the excretion of drugs that have an alkaline reaction (including alkaloids), and reduces the concentration of oral contraceptives in the blood.

Ethanol promotes the development of acute pancreatitis.

Myelotoxic drugs increase the manifestation of hematotoxicity of the drug.
