However, individuals with a known allergy to cow’s milk should avoid it.

4.6 Use in special populations

General Precautions: Due to the lack of comprehensive studies, it’s generally recommended to be cautious and it’s essential to consult with a healthcare provider before incorporating bovine colostrum into your diet during pregnancy or lactation.

4.7 Effects on ability to drive and use machines

There is no specific evidence to suggest that bovine colostrum has any direct effects on driving ability or use of machines. No effect anticipated.

4.8 Undesirable effects

• Colostrum is a high-protein, low fat and reduced lactose dairy product, as a result lactose-intolerant individuals generally experience no problems and some even report that colostrum helps with their condition. Colostrum used naturally contains low levels of lactose and during processing these are reduced further. If you can drink milk without any problem, then you can probably take colostrum.
• Some individuals may experience a mild gastrointestinal distress or a bloated feeling, which can be avoided by lowering the dose.
• If this reaction continues however then it is best to discontinue the colostrum treatment. However, as with all health supplements, it is always advisable to consult with your doctor in the first instance.

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 email to: medico@zuventus.com

By reporting side effects, you can help provide more information on the safety of this medicine.

4.9 Overdose

• Not to exceed the recommended daily usage.
• Overdosing on bovine colostrum is not well-documented, but taking it in excessive amounts could potentially lead to some side effects. Gastrointestinal Issues: High doses of bovine colostrum might cause nausea, bloating, diarrhea, or other digestive discomforts.
• In case of accidental overdose, contact a Healthcare Professional.

5.1 Pharmacodynamic properties

Bovine colostrum is a nutrient-rich fluid produced by cows in the first few days after giving birth. It’s packed with proteins, antibodies, and growth factors that help newborn calves thrive. For humans, bovine colostrum is often used in supplements due to its potential health benefits, such as boosting immunity, fighting infections, and promoting gut health.

This “early” milk has a nutrient profile and immunological composition significantly different from “mature” milk. In addition to macronutrients found in milk such as protein, carbohydrate, and fat, and micronutrients including vitamins and minerals, BC contain:

–Oligosaccharides,

–Growth factors,

– Antimicrobial compounds, &

– Immune-regulating constituents

either not present in milk or present in substantially lower concentrations.

Colostrum supports the human in two main ways.

1. Its multiple immune factors and natural antibiotics provide strong support for the immune system.

2.Its many growth factors offer a broad- spectrum boost to encourage optimum health and healing.

• The immunoglobulin, growth factors, antibodies play a role in prevention of infection that is in passive immunity.
• The vital nutrients help for tissue development, growth and energy.
• The growth factors present in the colostrum provide a novel treatment option for gastrointestinal conditions.

5.3 Pharmacokinetic properties

• Colostrum survives human GIT & works on mucosal surfaces: Bovine colostrum contains special glycoproteins and protease inhibitors which are extremely effective at protecting the destruction of colostrum’s active components (immunoglobulins and growth factors) by adult human digestive acids pancreatic enzymes and human stomach acids. This allows them to remain active as they pass into the bowel.
• The major benefit of immune factors from colostrum was shown to be their protective activity in the intestine on the walls of the bowel, and bronchials, (mucosal surfaces).
• The preservation of the biological activity of IgG (immunoglobulin) in the digestive secretions of adults receiving bovine immune colostrum orally indicates – passive enteral (intestinal) immunization for the prevention and treatment of acute intestinal diseases.
• Bovine colostrum has been shown to be safe, natural, effective & biologically transferable for human use.

6.1 Animal Toxicology or Pharmacology

Not available

Bovine Colostrum: Universal Donor of Colostrum to Human

• Only bovine colostrum has been shown to be safe, natural, effective & biologically transferable for human use.

4.4 Special warnings and precautions for use

CAUTION: Tablets are hygroscopic in nature. Exposure to humid conditions may soften the tablets affecting their appearance and shape. Cutting of strip should be avoided while dispensing/usage.

The label will state “Important warning: Contains Iron. Keep out of reach and sight of children, as overdose may be fatal”.

This will appear on the front of the pack within a rectangle in which there is no other information.

Some post-gastrectomy patients show poor absorption of iron. Care is needed when treating iron deficiency anemia in patients with treated or controlled peptic ulceration. Caution should be exercised when administering folic acid to patients who may have folate dependent tumors.

Since anemia due to combined iron and vitamin B12 or folate deficiencies may be microcytic in type, patients with microcytic anemia resistant to therapy with iron alone should be screened for vitamin B12 or folate deficiency.

Accumulation of zinc may occur in cases of renal failure.

Pregnancy

Safety is not established in pregnant women; therefore Feronia HP is not recommended in pregnancy.

Lactation

Safety is not established in lactating women; therefore Feronia HP is not recommended during lactation.

Pediatric population

Feronia HP Tablets should be kept out of the reach of children.

4.5 Interaction with other medicinal products and other forms of interaction

• Iron reduces the absorption of penicillamine. Iron compounds impair the bioavailability of fluoroquinolones, levodopa, carbidopa, thyroxine and bisphosphonates.
• Absorption of both iron and antibiotic may be reduced if Feronia HP is given with tetracycline.
• Concurrent administration of antacids may reduce absorption of iron. Co- trimoxazole, chloramphenicol, sulphasalazine, aminopterin, methotrexate, pyrimethamine or sulphonamides may interfere with folate metabolism. Serum levels of anticonvulsant drugs may be reduced by administration of folate.
• Oral chloramphenicol delays plasma iron clearance, incorporation of iron into red blood cells and interferes with erythropoiesis.
• Some inhibition of iron absorption may occur if it is taken with cholestyramine, trientine, tea, eggs or milk.
• Administration of oral iron may increase blood pressure in patients receiving methyldopa.
• Coffee may be a factor in reducing iron bioavailability. Neomycin may alter the absorption of iron.
• The absorption of zinc may be reduced by calcium supplements, tetracyclines and phosphorus-containing compounds, agents which increase gastric pH, such as H2 blockers, may decrease zinc absorption while zinc may reduce the absorption of penicillamine, tetracyclines, fluoroquinolones.

Food

Studies of the co-administration of zinc with food performed in healthy volunteers showed that the absorption of zinc was significantly delayed by many foods (including bread, hard boiled eggs, coffee and milk). Substances in food, especially phytates and fibres, bind zinc and prevent it from entering the intestinal cells. However, protein appears to interfere the least.

4.6 Fertility, pregnancy and lactation

4.9 Overdose

Symptoms

Symptoms and signs of abdominal pain, vomiting and diarrhea appear within 60 minutes. Cardiovascular collapse with coma may follow. Some improvement may occur after this phase which, in some patients, is followed by recovery. In others, after about 16 hours, deterioration may occur involving diffuse vascular congestion, pulmonary edema, convulsions, anuria, hypothermia, severe shock, metabolic acidosis, coagulation abnormalities and hypoglycemia.

Management

Vomiting should be induced immediately, followed as soon as possible by parenteral injection of desferrioxamine mesylate, and then gastric lavage. In the meantime, it is helpful to give milk and/or 5% sodium bicarbonate solution by mouth.

Dissolve 2g desferrioxamine mesylate in 2 to 3ml of water for injections and give intramuscularly. A solution of 5g desferrioxamine in 50 to 100ml of fluid may be left in the stomach. If desferrioxamine is not available, leave 300ml of 1 % to 5 % sodium bicarbonate in the stomach. Fluid replacement is essential.

Recovery may be complicated by long-term sequelae such as hepatic necrosis, pyloric stenosis or acute toxic encephalitis which may lead to CNS damage.

Treatment of overdose should be with gastric lavage or induced emesis as quickly as possible to remove unabsorbed zinc. Heavy metal chelation therapy should be considered if plasma zinc levels are markedly elevated (> 10 mg/l).

Pediatric population

Acute overdose of oral iron requires emergency treatment. In young children 200-250mg/kg Ferrous Ascorbate is considered to be extremely dangerous.

5.1 Mechanism of Action/ Pharmacodynamic properties

Iron absorption occurs predominantly in the duodenum and upper jejunum. Iron is oxidized to the Fe3+ state no matter its original form when taken in orally. Gastric acidity as well as solubilizing agents such as ascorbate prevent precipitation of the normally insoluble Fe3+. Intestinal mucosal cells in the duodenum and upper jejunum absorb the iron. The iron is coupled to transferrin (Tf) in the circulation which delivers it to the cells of the body. A feedback mechanism exists that enhances iron absorption in people who are iron deficient. In contrast, people with iron overload dampen iron absorption. A number of dietary factors influence iron absorption. Ascorbate increase iron uptake in part by acting as weak chelators to help to solubilize the metal in the duodenum. Iron is readily transferred from these compounds into the mucosal lining cells.

Zinc supplementation improves immunity.

Zinc deficiency also has direct effects on the gastrointestinal tract such as impaired intestinal brush border, increased secretion in response to bacterial enterotoxins and perturbations in intestinal permeability. Zinc supplementation improves the transport of water and electrolytes across the intestinal mucosa in experimental zinc deficiency.

Zinc plays a fundamental role in cellular metabolism and is postulated to modulate host resistance to various infections.

5.2 Pharmacokinetic properties

Absorption

Iron is absorbed chiefly in the duodenum and jejunum. Folic Acid is absorbed mainly from the proximal part of the small intestine.

Distribution

The amounts of Folic Acid absorbed from normal diets are rapidly distributed in body tissues.

Biotransformation

Absorption being aided by the acid secretion of the stomach and being more readily affected when the iron is in the ferrous state.

Folic acid rapidly appears in the blood, where it is extensively bound to plasma proteins.

When larger amounts are absorbed, a high proportion is metabolized in the liver to other active forms of folate and a proportion is stored as reduced and methylated folate.

Elimination

Larger amounts of folate are rapidly excreted in the urine and about 4 to 5 micrograms is excreted in the urine daily.

Zinc is absorbed in the small intestine and its absorption kinetics suggest a tendency to saturation at increasing doses. Fractional zinc absorption is negatively correlated with zinc intake. It ranges from 30 to 60% with usual dietary intake (7-15 mg/d) and decreases to 7% with pharmacological doses of 100 mg/d.

In the blood, about 80% of absorbed zinc is distributed to erythrocytes, with most of the remainder being bound to albumin and other plasma proteins. The liver is the main storage for zinc and hepatic zinc levels are increased during maintenance therapy with zinc. The plasma elimination half-life of zinc in healthy subjects is around 1 hour after a dose of 45 mg. The elimination of zinc results primarily from fecal excretion with relatively little from urine and sweat. The fecal excretion is in the greatest part due to the passage of unabsorbed zinc but it is also due to endogenous intestinal secretion.

This Product (tablet) contains: Ferrous Ascorbate, Folic Acid, Methylcobalamin and Zinc sulphate as active ingredients, for the treatment of iron deficiency anemia.

Ferrous Ascorbate is an iron supplement used to treat or prevent low blood levels of iron (such as those caused by anemia or during pregnancy). Ascorbic acid (vitamin C) improves the absorption of iron from the stomach.

Pediatric population

Feronia D3 Tablets should be kept out of the reach of children.

4.5 Interaction with other medicinal products and other forms of interaction

• Iron reduces the absorption of penicillamine. Iron compounds impair the bioavailability of fluoroquinolones, levodopa, carbidopa, thyroxine and bisphosphonates.
• Absorption of both iron and antibiotic may be reduced if Feronia D3 is given with tetracycline.
• Absorption of both iron and zinc are reduced if taken concomitantly. Concurrent administration of antacids may reduce absorption of iron. Co- trimoxazole, chloramphenicol, sulphasalazine, aminopterin, methotrexate, pyrimethamine or sulphonamides may interfere with folate metabolism. Serum levels of anticonvulsant drugs may be reduced by administration of folate.
• Oral chloramphenicol delays plasma iron clearance, incorporation of iron into red blood cells and interferes with erythropoiesis.
• Patients treated with cardiac glycosides may be susceptible to high calcium levels and should have ECG parameters and calcium levels monitored. It is recommended to reduce the dose or interrupt treatment if the calcium content in the urine exceeds 7.5 mmol/24 hours (300 mg/24 hours).
• Simultaneous administration of benzothiadiazine derivatives (thiazide diuretics) increases the risk of hypercalcaemia because they decrease the calcium excretion in the urine. The calcium levels in plasma and urine should therefore be monitored for patients undergoing long-term treatment.
• If Cholecalciferol is combined with metabolites or analogues of vitamin D careful monitoring of serum calcium levels is recommended.
• Some inhibition of iron absorption may occur if it is taken with cholestyramine, trientine, tea, eggs or milk.
• Administration of oral iron may increase blood pressure in patients receiving methyldopa.
• Coffee may be a factor in reducing iron bioavailability. Neomycin may alter the absorption of iron.
• Anti-convulsants e.g. phenytoin, phenobarbital, primidone may diminish the effect of Cholecalciferol due to hepatic enzyme induction.
• Rifampicin may reduce the effectiveness of Cholecalciferol due to hepatic enzyme induction.
• Isoniazid may reduce the effectiveness of Colecalciferol due to inhibition of the metabolic activation of Colecalciferol.
• Drugs leading to fat malabsorption, e.g. orlistat, liquid paraffin, cholestyramine, may impair the absorption of Cholecalciferol.
• The cytotoxic agent actinomycin and imidazole antifungal agents interfere with vitamin D activity.
• Concomitant use of glucocorticoids can decrease the effect of vitamin D.

4.6 Fertility, pregnancy and lactation

Pregnancy

The use of Feronia D3 Tablets may be considered during pregnancy, if necessary.

The development of anemia despite prophylaxis with Feronia D3 Tablets calls for investigation. During pregnancy women should follow the advice of their medical practitioner as their requirements may vary depending on the severity of their disease and their response to treatment.

Breast-feeding

It is unknown whether Ferrous Ascorbate and Folic Acid / metabolites are excreted in human milk.

A risk to the newborns/infants cannot be excluded.

Cholecalciferol and its metabolites are excreted in breast milk. Overdose in infants induced by nursing mothers has not been observed. However, when prescribing additional vitamin D to a breast-fed child the practitioner should consider the dose of any additional vitamin D given to the mother.

Fertility

No fertility data is available.

4.7 Effects on ability to drive and use machines

Feronia D3 Tablets has no influence on the ability to drive and use machines. Cholecalciferol has no known side effects that are likely to affect the ability to drive and use or operate machines.

4.8 Undesirable effects

4.9 Overdose

Symptoms

Symptoms and signs of abdominal pain, vomiting and diarrhea appear within 60 minutes. Cardiovascular collapse with coma may follow. Some improvement may occur after this phase which, in some patients, is followed by recovery. In others, after about 16 hours, deterioration may occur involving diffuse vascular congestion, pulmonary edema, convulsions, anuria, hypothermia, severe shock, metabolic acidosis, coagulation abnormalities and hypoglycemia.

Acute or chronic overdose of Cholecalciferol can cause hypercalcaemia, an increase in the serum and urinary concentrations of calcium. The symptoms of hypercalcaemia are not very specific and consist of nausea, vomiting, diarrhoea often in the early stages and later constipation, anorexia, fatigue, headache, muscle and joint pain, muscle weakness, polydipsia, polyuria formation of renal calculi, nephrocalcinosis, kidney failure, calcification of soft tissues, changes in ECG measurements, arrhythmias and pancreatitis. In rare and isolated cases there are reports that hypercalcaemia is fatal.

Management

Vomiting should be induced immediately, followed as soon as possible by parenteral injection of desferrioxamine mesylate, and then gastric lavage. In the meantime, it is helpful to give milk and/or 5% sodium bicarbonate solution by mouth.

Dissolve 2g desferrioxamine mesylate in 2 to 3ml of water for injections and give intramuscularly. A solution of 5g desferrioxamine in 50 to 100ml of fluid may be left in the stomach. If desferrioxamine is not available, leave 300ml of 1 % to 5 % sodium bicarbonate in the stomach. Fluid replacement is essential.

Recovery may be complicated by long-term sequelae such as hepatic necrosis, pyloric stenosis or acute toxic encephalitis which may lead to CNS damage.

A normalisation of hypercalcaemia due to vitamin D intoxication lasts several weeks. The recommendation for the treatment of hypercalcaemia is the avoidance of any further administration of vitamin D, including supplements, dietary intakes and the avoidance of sunlight. A low calcium or calcium-free diet can also be considered.

Rehydration and the treatment with diuretics e.g. furosemide to ensure adequate diuresis should be considered. Additional treatment with calcitonin or corticosteroids can also be considered.

Phosphate infusions should not be administered to lower hypercalcaemia of hypervitaminosis D because of the dangers of metastatic calcification.

Pediatric population

Acute overdose of oral iron requires emergency treatment. In young children 200-250mg/kg Ferrous Ascorbate is considered to be extremely dangerous.

5.1 Mechanism of Action/ Pharmacodynamic properties

Iron absorption occurs predominantly in the duodenum and upper jejunum. Iron is oxidized to the Fe3+ state no matter its original form when taken in orally. Gastric acidity as well as solubilizing agents such as ascorbate prevent precipitation of the normally insoluble Fe3+. Intestinal mucosal cells in the duodenum and upper jejunum absorb the iron. The iron is coupled to transferrin (Tf) in the circulation which delivers it to the cells of the body. A feedback mechanism exists that enhances iron absorption in people who are iron deficient. In contrast, people with iron overload dampen iron absorption. A number of dietary factors influence iron absorption. Ascorbate increase iron uptake in part by acting as weak chelators to help to solubilize the metal in the duodenum. Iron is readily transferred from these compounds into the mucosal lining cells.

Cholecalciferol is produced within the skin under the influence of UV radiation including sunlight. In its biologically active form, Cholecalciferol stimulates intestinal calcium absorption, incorporation of calcium into the osteoid, and release of calcium from bone tissue. In the small intestine it promotes rapid and delayed calcium uptake. The passive and active transport of phosphate is also stimulated. In the kidney, it inhibits the excretion of calcium and phosphate by promoting tubular resorption. The production of parathyroid hormone (PTH) in the parathyroids is inhibited directly by the biologically active form of Cholecalciferol. PTH secretion is inhibited additionally by the increased calcium uptake in the small intestine under the influence of biologically active Cholecalciferol.

Elimination: Cholecalciferol and other forms of vitamin D are excreted in feces and urine.

• Iron participates in the second activation step of vitamin D, necessary to make this hormone functional.
• This conversion is done by a renal 25-hydroxyvitamin D 1α-hydroxylase (1α-OHase) enzyme which comprises a CYP-450, a ferredoxin, and a ferredoxin reductase.
• Therefore, less available iron could compromise production of the active form of vitamin D.

5.2 Pharmacokinetic properties

Folic Acid is absorbed mainly from the proximal part of the small intestine.

Distribution

The amounts of Folic Acid absorbed from normal diets are rapidly distributed in body tissues.

Biotransformation

Absorption being aided by the acid secretion of the stomach and being more readily affected when the iron is in the ferrous state.

When larger amounts are absorbed, a high proportion is metabolized in the liver to other active forms of folate and a proportion is stored as reduced and methylated folate.

Elimination

Larger amounts of folate are rapidly excreted in the urine and about 4 to 5 micrograms is excreted in the urine daily.

The pharmacokinetics of Cholecalciferol have been widely studied and are well-known. Cholecalciferol from nutritional sources is almost completely absorbed from within the gastro-intestinal tract in the presence of dietary lipids and bile acids. Cholecalciferol is stored in fat cells and its biological half-life is approximately 50 days.

Cholecalciferol is metabolised by microsomal hydroxylase to form 25-hydroxycolecalciferol (25(OH)D3, calcidiol), the primary storage form of vitamin D3. 25(OH)D3 undergoes a secondary hydroxylation within the kidney to form the predominant active metabolite 1,25-hydroxycolecalciferol (1,25(OH)2D3, calcitriol). The metabolites circulate in the blood bound to a specific α -globin.

After a single oral dose of Cholecalciferol, the maximum serum concentrations of the primary storage form are reached after approximately 7 days. 25(OH)D3 is then slowly eliminated with an apparent half-life in serum of about 50 days. Cholecalciferol and its metabolites are excreted mainly in the bile and feces.

After high doses of Cholecalciferol, serum concentrations of 25(OH)D3 may be increased for months. Overdose-induced hypercalcemia may persist for weeks
