Approved Indications:

• Prevention of nutritional deficiencies in infants and children due to inadequate dietary intake.
• Treatment of confirmed vitamin and mineral deficiencies, especially in cases of malnutrition, gastrointestinal disorders, or chronic illnesses.
• Support during rapid growth phases (e.g., infancy, early childhood) when nutritional needs are higher.
• Post-illness recovery to restore depleted vitamin and mineral stores.
• Supplementation in children with restricted diets (e.g., picky eaters, vegetarian diets, or food allergies).
• Supportive therapy in children with chronic infections, frequent colds, or poor appetite.

Clinically Accepted Off-label Uses:

• Adjunctive therapy in children with developmental delays, anemia, or failure to thrive.
• Supplementation in children on long-term medications that may interfere with micronutrient absorption (e.g., anticonvulsants, corticosteroids).
• Immune support in frequently sick children.

Route: Oral (drops, syrup, chewable tablets, or dispersible tablets depending on age group and formulation)

Infants (0–12 months):

• Multivitamin-multimineral drops: 0.5 mL to 1 mL once daily with food or milk
• Dose varies based on manufacturer and concentration

Toddlers (1–3 years):

• Syrup or drops: 1 mL to 2.5 mL once daily
• Chewable tablets: Only if formulation allows and child can safely chew

Children (4–12 years):

• Syrup: 5 mL once daily
• Chewable/dispersible tablets: 1 tablet daily with meals

Adolescents (12–18 years):

• If pediatric formulation is still used: 1–2 tablets daily based on clinical judgment
• Otherwise, switch to age-appropriate adolescent or adult formulation

Special Populations:

• Malnourished or chronically ill children: May require dose adjustment or split dosing
• Renal or hepatic impairment: Use with caution; avoid high doses of fat-soluble vitamins (A, D, E, K) and minerals like iron or zinc

Administration Tips:

• Administer with meals to improve absorption and reduce GI upset
• Shake liquid formulations well before use
• Do not exceed recommended daily doses unless directed by a physician

Multivitamin and multimineral supplements work by providing essential micronutrients required for numerous metabolic, physiological, and developmental processes in the growing child. Water-soluble vitamins (e.g., B-complex, Vitamin C) function as coenzymes in energy metabolism, DNA synthesis, hematopoiesis, and immune responses. Fat-soluble vitamins (A, D, E, K) support vision, bone health, antioxidant activity, and blood coagulation. Key minerals such as iron, zinc, calcium, magnesium, and iodine are vital for hemoglobin synthesis, cellular growth, neural development, and endocrine function. Together, this supplement ensures optimal growth, immune function, and cognitive development during early life stages.

Absorption:

• Oral absorption varies by nutrient type.
• Water-soluble vitamins are rapidly absorbed in the small intestine.
• Fat-soluble vitamins require dietary fat and bile salts for optimal absorption.
• Minerals like iron and calcium have variable bioavailability based on gastric pH and dietary content.

Distribution:

• Water-soluble vitamins distribute in extracellular fluids and tissues.
• Fat-soluble vitamins accumulate in liver and adipose tissue.
• Minerals bind to proteins or are stored in bone and tissue compartments.

Metabolism:

• Most vitamins are metabolized in the liver.
• Minerals undergo minimal metabolism but are incorporated into enzymes or stored in bone.

Elimination:

• Water-soluble vitamins: Excreted via urine (rapid clearance)
• Fat-soluble vitamins: Slow elimination, risk of accumulation with overdose
• Minerals: Excreted via urine or feces depending on the element

Onset: Clinical effects observed over days to weeks, depending on the severity of deficiency

Half-life: Varies per component; water-soluble vitamins have shorter half-lives than fat-soluble ones

Pregnancy:

• Not applicable for pediatric use.
• However, individual components are generally considered safe during pregnancy at recommended daily allowances.

Lactation:

• Breastfed infants may require supplementation with Vitamin D and iron, especially after 6 months.
• Pediatric supplements should be used only under physician guidance in lactating infants.

Caution: Avoid excessive dosing of fat-soluble vitamins due to potential toxicity.

• Primary Class: Nutritional Supplement
• Subclass: Pediatric Multivitamin-Multimineral Combination

• Known hypersensitivity to any vitamin, mineral, or excipient
• Hypervitaminosis A or D
• Hemochromatosis or iron overload disorders (for formulations containing iron)
• Wilson’s disease (avoid excess copper or zinc)
• Severe renal impairment (formulations with high levels of calcium, phosphorus, or magnesium)

• Avoid overdose of fat-soluble vitamins; may lead to toxicity
• Use with caution in children with chronic renal or hepatic impairment
• Monitor iron and vitamin D levels in long-term use
• Keep out of reach of children; accidental overdose of iron-containing products can be fatal
• Avoid concurrent use with other vitamin-containing products unless advised by a healthcare provider

Common (usually mild):

• Gastrointestinal: Nausea, constipation, diarrhea, abdominal discomfort
• Oral: Bad taste, staining of teeth (liquid iron-containing forms)
• Skin: Mild rash or allergic reaction

Less Common:

• Hypervitaminosis symptoms (e.g., headache, irritability, fatigue from Vitamin A or D overdose)
• Iron-related GI irritation

Serious but Rare:

• Anaphylaxis (extremely rare)
• Vitamin A toxicity (e.g., bulging fontanelle, hepatotoxicity)
• Iron poisoning with overdose

• Calcium, magnesium, or iron: May interfere with absorption of antibiotics like tetracycline or ciprofloxacin
• Vitamin K: May interfere with warfarin (though warfarin use is rare in pediatric populations)
• Zinc and copper: Excessive zinc may reduce copper absorption
• Vitamin C: Enhances iron absorption
• Iron supplements: Avoid co-administration with milk or antacids (reduce absorption)

No major CYP450-mediated interactions reported for most pediatric multivitamin-mineral formulations.

• AAP (American Academy of Pediatrics) and WHO continue to emphasize selective vitamin supplementation in infants:
• Vitamin D: 400 IU daily for all breastfed infants
• Iron: Supplementation after 6 months in exclusively breastfed infants
• Pediatric multivitamins are now formulated to avoid megadoses of fat-soluble vitamins due to toxicity concerns
• New formulations include omega-3 DHA and choline to support neurodevelopment

• Store at below 25°C in a cool, dry place
• Protect from light and moisture
• Keep tightly closed; shake well before use (for liquids)
• Do not freeze liquid formulations
• Keep out of reach of children
• Check expiry date before administration
• For liquid formulations: Use within a specific time after opening (e.g., 30 days) as per manufacturer instructions
