Powder for solution for injection or infusion
CLINICAL PARTICULARS
4.
4.1. Therapeutic indications
Supply of vitamins corresponding to the daily needs of adults and children over 11 years requiring multi-vitamin supplementation by the parenteral route when oral nutrition is contraindicated, impossible or insufficient (e.g. due to malnutrition, gastrointestinal malabsorption, parenteral nutrition, etc).
4.2 Posology and method of administration
Dosage
Adults and children aged over 11 years : 1 vial/day.
Administration
Method of reconstitution: see section 6.6, Instruction for use and handling.
Intravenous route: By slow intravenous injection (at least 10 minutes) or by infusion in a solution of 5% glucose or 0.9% sodium chloride solution for infusion.
Cernevit may be included in the composition of nutritive mixtures combining carbohydrates, lipids, amino acids and electrolytes provided that compatibility and stability have been confirmed for each nutritive mixture, to meet nutrient needs and prevent deficiencies and complications from developing.
The total vitamin amounts from all sources such as nutritional sources, other vitamin supplements, or medications that contain vitamins as inactive ingredients (see Section 4.5) should be considered.
The patient’s clinical status and vitamin levels should be monitored to ensure maintenance of adequate levels.
It should be taken into account that some vitamins, especially A, B2, and B6 are sensitive to ultraviolet light (e.g., direct or indirect sun light). In addition, loss of vitamins A, B1, C, and E may increase with higher levels of oxygen in the solution. These factors should be considered if adequate vitamin levels are not achieved.
4.3 Contraindications
CERNEVIT must not be used in:
hypersensitivity to the active substances, especially vitamin B1 or to any of the excipients listed in section 6.1, including soy protein/products (lecithin in mixed micelle is soy-derived),
hypervitaminosis from any vitamin contained in this formulation,
4.4 Special warnings and precautions for use
WARNINGS
Hypersensitivity Reactions
• Severe systemic hypersensitivity reactions have been reported with Cernevit, other multivitamin preparations, and individual vitamins (including B1, B2, B12 and folic acid). Reactions with fatal outcome have been reported with Cernevit and other parenteral vitamin products (See Section 4.8).
• In some cases, the manifestations of a hypersensitivity reaction during intravenous administration of multivitamins may be rate related. If infused intravenously, Cernevit should be administered slowly. If injected intravenously, the injection must be administered slowly (over at least 10 minutes).
• The infusion or injection must be stopped immediately if signs or symptoms of a hypersensitivity reaction develop.
Vitamin Toxicity
• The patient’s clinical status and blood vitamin concentrations should be monitored to avoid overdose and toxic effects, especially with vitamins A, D and E, and in particular in patients who receive additional vitamins from other sources or use other agents that increase the risk of vitamin toxicity.
• Monitoring is particularly important in patients receiving long-term supplementation.
Hypervitaminosis A
• The risk for hypervitaminosis A and vitamin A toxicity (e.g., skin and bone abnormalities, diplopia, cirrhosis) is increased in, for example:
-patients with protein malnutrition,
-patients with renal impairment (even in the absence of vitamin A supplementation),
-patients with hepatic impairment,
-patients with small body size (e.g., paediatric patients), and
• Acute hepatic disease in patients with saturated hepatic vitamin A stores can lead to the manifestation of vitamin A toxicity.
Refeeding Syndrome in Patients Receiving Parenteral Nutrition
Refeeding severely undernourished patients may result in refeeding syndrome that is characterized by the shift of potassium, phosphorus, and magnesium intracellularly as the patient becomes anabolic. Thiamine deficiency and fluid retention may also develop. Careful monitoring and slowly increasing nutrient intakes while avoiding overfeeding can prevent these complications. Should nutrient deficiencies occur, appropriate supplementation may be warranted.
Precipitates in Patients Receiving Parenteral Nutrition
Pulmonary vascular precipitates have been reported in patients receiving parenteral nutrition. In some cases, fatal outcomes have occurred. Excessive addition of calcium and phosphate increases the risk of the formation of calcium phosphate precipitates. Precipitates have been reported even in the absence of phosphate salt in the solution. Precipitation distal to the in-line filter and suspected precipitate formation in the blood stream have also been reported.
In addition to inspection of the solution, the infusion set and catheter should also periodically be checked for precipitates.
If signs of pulmonary distress occur, the infusion should be stopped and medical evaluation initiated.
PRECAUTIONS
Hepatic Effects
• Monitoring of liver function parameters is recommended in patients receiving Cernevit. Particularly close monitoring is recommended in patients with hepatic jaundice or other evidence of cholestasis.
In patients receiving Cernevit, instances of liver enzyme increases have been reported, including isolated alanine aminotransferase (ALT) increases in patients with inflammatory bowel disease (see section 4.8).
In addition, an increase in bile acid levels (total and individual bile acids including glycocholic acid) have been reported in patients receiving Cernevit.
• Hepatobiliary disorders including cholestasis, hepatic steatosis, fibrosis and cirrhosis, possibly leading to hepatic failure, as well as cholecystitis and cholelithiasis are known to develop in some patients on parenteral nutrition (including vitamin supplemented parenteral nutrition). The etiology of these disorders is thought to be multifactorial and may differ between patients. Patients developing abnormal laboratory parameters or other signs of hepatobiliary disorders should be assessed early by a clinician knowledgeable in liver diseases
in order to identify possible causative and contributory factors, and possible therapeutic and prophylactic interventions.
Use in Patients with Impaired Hepatic Function
Patients with hepatic impairment may need individualized vitamin supplementation. Particular attention should be placed on preventing vitamin A toxicity, because the presence of liver disease is associated with increased susceptibility to vitamin A toxicity, in particular in combination with chronic excessive alcohol consumption (See also Hypervitaminosis A and Hepatic Effects above).
Use in Patients with Impaired Renal Function
Patients with renal impairment may need individualized vitamin supplementation, depending on the degree of renal impairment and the presence of concomitant medical conditions. In patients with severe renal impairment, particular attention should be placed on maintaining adequate vitamin D status and preventing vitamin A toxicity, which may develop in such patients with low-dose vitamin A supplementation or even without supplementation.
Pyridoxine (vitamin B6) hypervitaminosis and toxicity (peripheral neuropathy, involuntary movements) have been reported in patients on chronic haemodialysis receiving intravenous multivitamins containing 4 mg pyridoxine administered three times a week.
General Monitoring
Clinical status and vitamin levels should be monitored in patients receiving parenteral multivitamins as the only source of vitamins for extended periods of time. It is particularly important to monitor for adequate supplementation of, for example:
• Vitamin A in patients with pressure ulcers, wounds, burns, short bowel syndrome or cystic fibrosis
• Vitamin B1 in dialysis patients
• Vitamin B2 in cancer patients
• Vitamin B6 in patients with renal impairment
• Individual vitamins whose requirements may be increased due to interactions with other medicines (see section 4.5).
Deficiency of one or more vitamins must be corrected by specific supplementation.
Vitamin K
Cernevit does not contain Vitamin K. Vitamin K must be administered separately if necessary.
Evaluation of vitamin B12 status is recommended before starting supplementation with Cernevit in patients at risk for vitamin B12 deficiency and/or when supplementation with Cernevit over several weeks is planned.
After several days of administration, both the individual amounts of cyanocobalamin (vitamin B12) and folic acid in Cernevit may be sufficient to result in an increase in red blood cell count, reticulocyte count, and haemoglobin values in some patients with vitamin B12 deficiency-associated megaloblastic anaemia. This may be masking an existing vitamin B12 deficiency. Effective treatment of vitamin B12 deficiency requires higher doses of cyanocobalamin than provided in Cernevit.
Folic acid supplementation in patients with vitamin B12 deficiency, who do not also receive vitamin B12, does not prevent the development or progression of neurologic manifestations associated with the vitamin B12 deficiency. It has been suggested that neurologic deterioration may even be accelerated.
When interpreting levels of vitamin B12, it should be taken into account that recent intake of vitamin B12 may result in normal levels despite a tissue deficiency.
Laboratory Test Interferences
Depending on the reagents used, the presence of ascorbic acid in blood and urine may cause false high or low glucose readings in some urine and blood glucose testing systems, including test strips and handheld glucose meters. The technical information for any laboratory test should be consulted to determine the potential interference from vitamins.
Sodium Content
Cernevit contains 24 mg sodium (1 mmoL) per vial. This should be taken into consideration if patients are on a controlled sodium diet.
Paediatric Use
Cernevit is indicated in paediatric patients over 11 years of age (see also Section 4.4: Hypervitaminosis A above).
Geriatric Use
In general, dosage adjustments for an elderly patient should be considered (reducing the dose and/or extending the dosing intervals) reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy.
4.5 Interaction with other medicinal products and other forms of interaction
Interactions between specific vitamins in Cernevit and other agents should be managed accordingly.
Such interactions include:
Agents that can cause pseudotumor cerebri (including certain tetracyclines): Increased risk for pseudotumor cerebri by concomitant administration of Vitamin A
Alcohol (chronic excessive consumption): Increases the risk of vitamin A hepatotoxicity
Anticonvulsants (phenytoin, fosphenytoin, phenobarbital, primidone): Folic acid supplementation can decrease the anticonvulsant serum concentration and increase seizure risk.
Antiplatelet agents (e.g., aspirin): Vitamin E can add to the inhibition of platelet function
Aspirin (high dose therapy): Can reduce folic acid levels by increasing urinary excretion
Certain anticonvulsants (e.g., phenytoin, carbamazepine, phenobarbital, valproate): Can cause folate, pyridoxine and vitamin D deficiencies
Certain antiretroviral agents: Decreased vitamin D levels have been associated with, e.g., efavirenz and zidovudine. Decreased formation of the active vitamin D metabolite has been associated with protease inhibitors.
Chloramphenicol: Can inhibit the haematological response to vitamin B12 therapy
Deferoxamine: Increased risk of iron-induced cardiac failure due to increased iron mobilization by supraphysiologic vitamin C supplementation. For specific precautions, refer to deferoxamine product information.
Ethionamide: Can cause pyridoxine deficiency
Fluoropyrimidines (5-fluorouracil, capecitabine, tegafur): Increased cytotoxicity when combined with folic acid
Folate antagonists, e.g., methotrexate, sulfasalazine, pyrimethamine, triamterene, trimethoprim, and high doses of tea catechins: Block the conversion of folate to its active metabolites and reduce the effectiveness of supplementation
Folate antimetabolites (methotrexate, raltitrexed): Folic acid supplementation can decrease the antimetabolite effects
Levodopa: The content of pyridoxine may interfere with the effects of concurrent levodopa therapy.
Pyridoxine antagonists, including cycloserine, hydralazine, isoniazid, penicillamine, phenelzine: Can cause pyridoxine deficiency
Retinoids, including bexarotene: Increase the risk of toxicity when used concomitantly with vitamin A (see section 4.4: Hypervitaminosis A)
Theophylline: Can cause pyridoxine deficiency
Tipranavir oral solution: Contains 116 IU/mL of vitamin E, which is in excess of the daily recommended intake
Vitamin K antagonists (e.g., warfarin): Enhanced anticoagulant effect by vitamin E
Drugs that Bind to alpha1-Acid Glycoprotein (AAG):
In an in vitro study using human serum, concentrations of glycocholic acid approximately 4 times higher than the glycocholic acid serum concentration that would result from a bolus injection of Cernevit in adults, increased the unbound fraction of selected drugs known to bind to alpha1-acid glycoprotein (AAG) by 50-80%.
It is not known whether this effect is clinically relevant if the amount of glycocholic acid contained in a standard Cernevit dose (as a component of the mixed micelles) is administered by slow intravenous injection, intramuscular injection, or infused over a longer period of time.
Patients receiving Cernevit as well as drugs that bind to AAG should be closely monitored for increases in response of these drugs. These include propranolol, prazosin, and numerous others.
Interactions with Additional Vitamin Supplementation:
Some medications can interact with certain vitamins at doses markedly higher than those provided with Cernevit. This should be taken into consideration in patients receiving vitamins from multiple sources, and when applicable, patients should be monitored for such interactions and managed accordingly.
Such interactions include:
• Amiodarone: Concomitant use of vitamin B6 can enhance amiodarone-induced photosensitivity.
• Agents with anticoagulant effects (e.g., such as abciximab, clopidogrel, heparin, warfarin): Increased bleeding risk due to additional risk of bleeding associated with high vitamin A doses
• Carbamazepine: Inhibition of metabolism associated with large nicotinamide doses
• Chemotherapeutic agents that rely on the production of reactive oxygen species for their activity: Possible inhibition of chemotherapy activity by the antioxidant effects of high doses of vitamin E
• Insulin, antidiabetic agents: Decreased insulin sensitivity associated with large nicotinamide doses
• Iron: High dose-supplementation with vitamin E may reduce the haematological response to iron in anaemic patients
• Oral contraceptives (combination hormone types): High doses of vitamin C have been associated with breakthrough bleeding and contraceptive failure
• Phenobarbital: Increased metabolism/lower serum levels and reduced effect associated with large pyridoxine doses
• Phenytoin, fosphenytoin: Lower serum levels associated with large pyridoxine doses
• Primidone: Decreased metabolism to phenobarbital and increased primidone levels associated with large nicotinamide doses
Pernicious anaemia
The folic acid in Cernevit may obscure pernicious anaemia.
4.6 Fertility, pregnancy and lactation
The vitamin requirements for pregnant and lactating women may exceed those of non-pregnant and non-lactating women. Pregnant and lactating women should follow recommended daily allowances for their condition.
Carefully consider the potential risks and benefits for each specific patient before administering Cernevit.
4.7 Effects on ability to drive and use machines
There is no information on the effects of Cernevit on the ability to operate an automobile or other heavy machinery.

No symptoms of hypervitaminosis A were reported
3
Elevated plasma vitamin A levels have been reported in 8 of 20 patients receiving Cernevit in parenteral nutrition at day 45 of administration. From day 45 to day 90 of product administration the high values of vitamin A remained stable (maximum observed value of 3.6 pmol/L at day 90; normal values: 1 to 2.6 pmol/L). In addition, an average increase in retinol binding protein (RBP) was also identified. A maximum observed RBP value of 60 mg/L at day 90 (normal values: 30 to 50 mg/L), was reported.
4 Isolated alanine aminotransferase increases was reported in the presence of inflammatory bowel disease. Cernevit was administered by intravenous injection in the absence of parenteral nutrition.
5 An increase in total and individual bile acids including glycocholic acid has been reported to develop early in the course of parenteral nutrition administration in patients receiving Cernevit.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme.
Website: www.mhra.gov.uk/yellowcard
4.9 Overdose
Acute or chronic overdose of vitamins (in particular A, B6, D, and E) can cause symptomatic hypervitaminosis.
The risk of overdose is particularly high if a patient receives vitamins from multiple sources and overall supplementation of a vitamin does not match the patient’s individual requirements, and in patients with increased susceptibility to hypervitaminosis (see section 4.4).
Treatment of vitamin overdose usually consists of withdrawal of the vitamin and other measures as clinically indicated.
