Prenatal Vitamins
- Vitamins used to treat and prevent deficiencies during pregnancy.
- Special formulations include prenatal multiple vitamins with higher folic acid dose.
- Well absorbed via oral administration; absorption of water-soluble vitamins increases in deficiency states.
- Fat-soluble vitamins (A, D, E, K) stored in fatty tissues and liver.
- Contraindications include hypersensitivity to specific preservatives, colorants, or additives.
- Common adverse effects: nausea/vomiting; urine discoloration may occur with B vitamin preparations.
- Dosage recommendation: One tablet daily, started upon pregnancy confirmation.
- Large doses of vitamin B may affect levodopa efficacy.
- Emphasis on the necessity of a balanced diet in conjunction with prenatal vitamin supplementation.
Ferrous Sulfate (Iron)
- Iron supplement used to treat and prevent iron deficiency anemia.
- Optimal absorption via sulfate form; recommended dosage is one tablet, once or twice daily.
- Approximately 5-10% of dietary iron absorbed; higher absorption in deficiency states.
- Contraindicated in anemia not due to iron deficiency, hemochromatosis, and hypersensitivity to iron products.
- Adverse effects may include nausea, vomiting, constipation, dark stools, and risk of poisoning in children.
- Doses of ascorbic acid ≥200 mg may enhance iron absorption.
- Food can significantly reduce iron absorption; certain medications may also interfere with efficacy.
- Regular monitoring of hemoglobin, hematocrit, reticulocyte values, and iron levels is essential.
- Teaching includes dietary adjustments, safe storage away from children, and hydration for constipation relief.
Folic Acid
- Water-soluble vitamin essential for fetal development, facilitating neural tube growth and closure.
- Supports cell production and division, including red blood cells.
- Well absorbed from GI tract; also available via intramuscular and subcutaneous routes.
