If there is no relief of symptoms within 3 days after starting the drug, you should see a doctor.

Patients with hepatic impairment

Patients with impaired liver function or Gilbert syndrome need to reduce the dose or increase the interval between doses of the drug.

Patients with renal impairment

In the presence of acute renal impairment (creatinine clearance less than 10 ml/min), the interval between doses of the drug should be at least 8 hours.

Elderly patients

Dose adjustment is not necessary in elderly patients.

Interaction

Influence of ascorbic acid

Concomitant use with barbiturates, primidone, tetracycline increases excretion of ascorbic acid in the urine.

Concomitant use of oral contraceptives decreases the concentration of ascorbic acid in plasma.

Possible increase in plasma concentrations of ethinylestradiol when used concomitantly with oral contraceptives.

In concomitant use with iron preparations, ascorbic acid, due to its reducing properties, converts trivalent to divalent iron, which helps to improve its absorption.

Ascorbic acid in high doses may decrease urinary pH, which with concomitant use reduces the tubular reabsorption of amphetamine and tricyclic antidepressants.

Concomitant use of acetylsalicylic acid reduces absorption of ascorbic acid by about a third.

Concomitant use with warfarin may reduce the effects of warfarin.

Influence of calcium gluconate

In concomitant use calcium gluconate slows absorption of tetracyclines, digoxin, oral iron drugs (interval between their doses should be at least 2 hours).

In concomitant use with colestyramine the absorption of calcium from the gastrointestinal tract is decreased.

Calcium gluconate during concomitant use decreases hypotensive effect of calcium channel blockers (IV administration of calcium gluconate before and after verapamil decreases its hypotensive effect).

Parenteral administration of calcium gluconate is not recommended during treatment with cardiac glycosides (potentiation of cardiotoxic effect is possible). Concomitant use with quinidine may slow intraventricular conduction and increase quinidine toxicity.

In combination with thiazide diuretics calcium gluconate may increase hypercalcemia, decrease of calcitonin effect in hypercalcemia, decrease phenytoin bioavailability.

Influence of paracetamol

Accelerates the effects of MAO inhibitors, sedatives, ethanol.

The risk of hepatotoxic effects of paracetamol increases with concomitant administration of barbiturates, phenytoin, phenobarbital, carbamazepine, rifampicin, isoniazid, zidovudine and other inducers of microsomal liver enzymes.

The anticoagulant properties of warfarin and other coumarins may be enhanced with long-term regular use of paracetamol, increasing the risk of bleeding. Single administration of paracetamol has no such effect. Metoclopramide increases the absorption rate of paracetamol and increases the plasma concentration of paracetamol to a maximum. Similarly, domperidone may increase the absorption rate of paracetamol.

When chloramphenicol and paracetamol are used together the elimination half-life of chloramphenicol may be increased.

Paracetamol may decrease the bioavailability of lamotrigine with possible reduction of its action due to induction of its hepatic metabolism. Absorption of paracetamol may be reduced when concomitantly taken with colestyramine, but this can be avoided if colestyramine is taken one hour later than paracetamol.

The regular use of paracetamol concomitantly with zidovudine may cause neutropenia and increase the risk of liver damage. Probenecid affects the metabolism of paracetamol. In patients taking probenecid concomitantly, the dose of paracetamol should be reduced.

The hepatotoxicity of paracetamol may be increased with chronic or excessive alcohol consumption. Paracetamol may affect the results of a uric acid test using a precipitating reagent phosphovolframate.

Influence of rutoside

Ascorbic acid enhances the effects of rutoside.

Effects of phenylephrine

The drug is contraindicated in patients who are taking or have taken MAOI inhibitors within the last two weeks. MAOI inhibitors, tricyclic antidepressants (e.g., amitriptyline), ergot alkaloids, and sympathomimetics increase the pressor effect, and the latter and arrhythmogenicity of phenylephrine.

Phenylephrine may decrease the effectiveness of beta-adrenal blockers and other hypotensive drugs (e.g., debrisochine, guanethidine, reserpine, methyldopa). There is an increased risk of arterial hypertension.

The concomitant use of phenylephrine with digoxin and other cardiac glycosides may increase the risk of arrhythmia or myocardial infarction.

The thyroid hormones increase (reciprocally) the risk of coronary artery disease (especially in coronary atherosclerosis).

Alpha-adrenoblockers (phentolamine), phenothiazines, furosemide and other diuretics prevent vasoconstriction.

Influence of pheniramine

The effects of other substances on the central nervous system (e.g., MAO inhibitors, tricyclic antidepressants, alcohol, antiparkinsonian drugs, barbiturates, tranquilizers, and narcotic drugs) may be enhanced. Pheniramine may inhibit the effect of anticoagulants.

Special Instructions

To avoid toxic liver damage, the drug should not be combined with the use of alcoholic beverages.

Patients should consult a physician if:

• have bronchial asthma, emphysema, or chronic bronchitis;
• symptoms do not resolve within 5 days or are accompanied by severe fever lasting for 3 days, rash, or persistent headache.

These may be signs of more serious disorders.

The drug contains 200 mg of sodium citrate per bag. This should be taken into consideration by patients on a sodium diet.

The product should not be used from damaged sachets.

The drug should not be taken at the same time as other drugs containing paracetamol.

Influence on the ability to drive vehicles, machinery

Pheniramine contained in the contents of the bag “Night” may cause drowsiness, so during treatment it is not recommended to drive and engage in other activities requiring concentration and high speed of psychomotor reactions.

Overdose

The most dangerous symptoms of drug overdose can be caused by paracetamol.

Paracetamol

Symptoms (occur after a single dose of 7.5-10 g of paracetamol): In severe cases of overdose, paracetamol has hepatotoxic effects, including can cause liver necrosis. Also overdose can cause nephropathy with irreversible liver failure.

The severity of overdose depends on the dose, so patients should be warned against taking paracetamol-containing drugs at the same time. The risk of poisoning is especially high in elderly patients, children, patients with liver disease, in cases of chronic alcoholism, in patients with chronic malnutrition (caloric deficit) and in patients taking microsomal oxidation inducers in the liver.

Paracetamol overdose can lead to liver failure, encephalopathy, coma, and death.

The symptoms of paracetamol overdose in the first 24 hours are pale skin, nausea, vomiting, anorexia, seizures. Abdominal pain may be the first sign of liver damage and is usually not manifested during the first 24-48 hours and may sometimes appear later, 4-6 days later, on average 72-96 hours after taking the drug. Impaired glucose metabolism and metabolic acidosis may also occur. Even in the absence of liver damage, acute renal failure and acute tubular necrosis may develop. Cases of cardiac arrhythmias and development of pancreatitis have been reported in paracetamol overdose.

Treatment: administration of acetylcysteine intravenously or orally as an antidote, gastric lavage, and oral methionine administration may have a positive effect for at least the first 48 hours after overdose.

The administration of activated charcoal, respiratory and circulatory monitoring is recommended. Diazepam may be administered if seizures develop.

Ascorbic acid

Symptoms: If more than 1 g per day is taken, heartburn, diarrhea, difficulty urinating or staining urine red, hemolysis (in patients with glucose-6-phosphate dehydrogenase deficiency) may occur.

Calcium gluconate

Symptoms: The development of hypercalcemia: nausea, vomiting, severe weakness, thirst, drowsiness, disorientation, confusion, renal failure. Maximum daily dose for adults and children over 12 years old is 9 g.

Treatment: Calcitonin intravenous drip 5-10 IU/kg per day (the drug is diluted in 500 ml of isotonic sodium chloride solution, administered for 6 hours).

Pheniramine and phenylephrine (overdose symptoms are combined because of the risk of mutual potentiation of the parasympatholytic effect of pheniramine and the sympathomimetic effect of phenylephrine in case of drug overdose).

Symptoms: drowsiness, which is later joined by anxiety (especially in children), visual disturbances, rash, nausea, vomiting, headache, increased excitability, dizziness, insomnia, circulatory disorders, coma, seizures, behavior changes, increase or decrease of blood pressure, bradycardia. Cases of atropine-like “psychosis” have been reported in cases of pheniramine overdose.

Treatment. There is no specific antidote. Routine measures of care are necessary, including administration of activated charcoal, saline laxatives, and measures to support cardiac and respiratory function. Psychostimulants (methylphenidate) should not be administered because of the risk of seizures. Vasopressor drugs may be used in case of hypotension.

In case of high blood pressure, intravenous administration of alpha-adrenoblockers is possible, because phenylephrine is a selective agonist of alpha1-adrenoreceptors, therefore, the hypertensive effect in case of phenylephrine overdose should be treated by blocking the alpha-adrenoreceptors. Diazepam should be used if seizures develop.

Pregnancy use

The drug is not recommended for use during pregnancy and breastfeeding, due to the lack of data on the safe use of the drug in these persons.
