Orazinc-B

Orazinc-B oral syrup is used for:

• Treatment of latent iron deficiency and iron deficiency anaemia, including nutritional anaemia in infants and anaemia associated with excessive blood loss or chronic illness
• Prevention and treatment of iron deficiency anaemia before, during, and after pregnancy, and during breastfeeding
• Prophylactic supplementation of iron to help meet the recommended daily dietary allowance in individuals at risk of deficiency

This oral syrup combines iron in the form of iron (III) hydroxide polymaltose complex with B-group vitamins and zinc. A composition commonly seen across marketed Bangladeshi brands, per 5 mL, is: elemental Iron 50 mg (as iron (III) hydroxide polymaltose complex), Thiamine/Vitamin B1 5 mg, Riboflavin/Vitamin B2 2 mg, Pyridoxine/Vitamin B6 2 mg, Nicotinamide/Vitamin B3 20 mg, and elemental Zinc 10 mg. However, this generic name does not guarantee a single fixed concentration - other marketed products may use different amounts of each component. Always confirm the exact strength on the specific product's own label before determining a dose.

Orazinc-B oral iron supplement that pairs iron polymaltose complex with B-group vitamins and zinc, used to treat and prevent iron deficiency and iron deficiency anaemia. Iron polymaltose complex is a non-ionic iron preparation designed for more controlled absorption than simple iron salts, which may reduce gastrointestinal irritation. The added B vitamins and zinc support red blood cell formation and general nutritional status, particularly in infants, children, and pregnant or breastfeeding women.

Therapeutic Class: Haematinic (Iron and multivitamin/mineral supplement)

Iron (III) hydroxide polymaltose complex allows controlled release and absorption of iron at the intestinal mucosal surface. Because the iron is complex-bound rather than free ionic iron, it is less likely to interact with dietary components (such as phytates, oxalates, and tannins) or with certain co-administered medicines (such as tetracyclines and antacids) compared to conventional ionic iron salts. Absorbed iron is used for haemoglobin synthesis and other iron-dependent processes in the body. The B vitamins support red blood cell maturation and metabolic function, while zinc supports enzymatic and immune processes.

Orazinc-B is taken by mouth, generally after meals, which may help reduce the mild gastrointestinal upset that iron supplements can occasionally cause. Because the iron is complex-bound and non-ionic, this preparation is less likely than conventional iron salts to interact with food or certain medicines, though it should still be taken as directed and spaced from other medicines if advised by a pharmacist.

Because the iron in this preparation is complex-bound (non-ionic), interactions with dietary components (phytates, oxalates, tannins) and with medicines such as tetracyclines or antacids are less likely than with conventional ionic iron salts. Nonetheless, the following should be assessed by a healthcare professional:

• Antacids, which may reduce iron absorption
• Penicillamine, whose effects may be reduced by concurrent iron
• Bisphosphonates, tetracyclines, and quinolone antibiotics, where combined administration may reduce absorption of either agent and is generally spaced apart

Common side effects

• Nausea
• Vomiting
• Constipation or diarrhoea
• Dark coloration of the stool (a harmless effect of oral iron)

Allergic reactions are uncommon; seek medical attention for rash, swelling, or difficulty breathing.

Pregnancy

Orazinc-B is commonly recommended for the prevention and treatment of iron deficiency during pregnancy, when guided by a healthcare professional, as pregnancy increases iron requirements.

Breastfeeding

Orazinc-B is also commonly used during breastfeeding to support maternal iron status, under medical guidance.

• Use with caution in patients with a risk of iron overload, such as those with haemochromatosis, thalassemia, haemosiderosis, or haemolytic anaemia.
• Use with caution in patients with inflammatory bowel disease, peptic ulcer disease, or enteritis, as these conditions may enhance iron absorption and could worsen with excess iron.
• Keep out of reach of children, as accidental overdose of iron-containing products in young children can be serious.

Overdose of iron-containing products may cause nausea, vomiting, abdominal pain, and diarrhoea. Severe overdose, particularly in young children, can lead to more serious effects such as hypovolemic shock, liver toxicity, and metabolic acidosis, and constitutes a medical emergency requiring immediate care. Do not attempt home treatment; seek emergency medical attention promptly if overdose is suspected, especially in a child.

Store the syrup at room temperature, away from direct sunlight and moisture, and keep tightly closed and out of reach of children. Exact storage instructions may vary by product; follow the label directions.

• Pregnant and breastfeeding women: Commonly used to prevent and treat iron deficiency, under medical guidance.
• Infants and young children: Dosing is weight-based (0.33 mL/kg/day) and should be measured accurately; keep the product safely out of reach to prevent accidental ingestion.
• Patients with iron overload risk: Use with caution and appropriate monitoring, as described under precautions.

Duration of treatment depends on whether the product is used for prophylaxis or for correcting an established iron deficiency; treatment for confirmed iron deficiency anaemia is often continued for several weeks to months, and response should be monitored by the treating physician, who may check blood counts periodically.

Drug Class: Oral iron replacement (polysaccharide-iron complex) combined with B-complex vitamins and zinc

Iron is an essential component of haemoglobin, the protein in red blood cells that carries oxygen; supplementing iron corrects or prevents the anaemia that develops when iron stores are insufficient to meet the body's needs. The accompanying B-group vitamins support the biochemical pathways involved in red blood cell production, while zinc contributes to various metabolic and immune functions in the body.

Orazinc-B is used in infants and children for the treatment and prevention of iron deficiency anaemia, with dosing based on age or weight as shown in the dosage table above. The syrup form is well-suited to children and infants who cannot swallow tablets; doses should be measured accurately using an appropriate measuring device, and the product kept safely out of children's reach to prevent accidental overdose.
