Zif-A is a tablet containing a combination of:

• Ferrous Ascorbate: Equivalent to 48 mg of elemental iron.
• Folic Acid: 0.50 mg (500 mcg).
• Zinc Sulfate Monohydrate: Equivalent to 22.5 mg of elemental zinc.

It is manufactured by Square Pharmaceuticals Ltd. in Bangladesh.

Indications:

Zif-A is indicated for the prophylaxis (prevention) of deficiencies of iron, folic acid, and zinc, especially:

• During pregnancy.
• In cases of anemia due to iron deficiency.
• When the diet is inadequate in these nutrients.

Dosage and Administration:

• Adults and Elderly: Usually one tablet daily, before or after a meal (absorption is food-independent), or as directed by a physician.
• In more severe cases, two tablets daily may be prescribed.
• Pediatric patients: Safety and effectiveness in children have not been established.

Pharmacology:

• Ferrous Ascorbate: A stable chelate of iron and ascorbic acid (Vitamin C), which enhances iron absorption. Iron is essential for hemoglobin production and oxygen transport.
• Folic Acid: A B vitamin crucial for red blood cell formation, DNA synthesis, and cell division. It is vital during pregnancy for the development of the baby's brain and spinal cord.
• Zinc: An essential mineral involved in numerous bodily functions, including immune function, wound healing, and the function of many enzymes.

Side Effects:

The most common side effects are usually mild and transient and can include:

• Epigastric pain (upper abdominal pain)
• Heartburn
• Nausea
• Vomiting
• Diarrhea
• Constipation

Allergic sensitization has also been reported with folic acid.

Precautions:

• Care should be taken in patients who may develop iron overload (e.g., those with hemochromatosis, hemolytic anemia, or red cell aplasia).  
• Failure to respond to treatment may indicate other causes of anemia that need investigation.   
• In patients with renal failure, there may be a risk of zinc accumulation.

Contraindications:

Zif-A is contraindicated in patients with:

• Known hypersensitivity to any of its ingredients.
• Hemolytic anemia.
• Conditions with increased body iron content.

Pregnancy and Lactation:

• Use in the first trimester of pregnancy should be avoided unless there is definite evidence of iron deficiency.
• Prophylaxis of iron deficiency is justified during the remainder of pregnancy, especially when zinc supplementation is also required.
• During breastfeeding, it is advised to consult a physician before taking or continuing the drug.

Drug Interactions:

• Iron can chelate with tetracycline antibiotics, potentially reducing the absorption of both. Avoid taking Zif-A within two hours of tetracycline antibiotics.
• The absorption of iron may be reduced by concurrent use of penicillamine and antacids.

Storage:

Store below 30°C and keep out of reach of children.
