What is Vitamin A Chewable Tablet?
Vitamin A Chewable Tablet is manufactured by Generic as a chewable Vitamin A 50,000 IU tablet. Vitamin A (retinol) is essential for ocular surface health, photoreceptor function (rhodopsin synthesis), and epithelial integrity throughout the body. Deficiency is the leading cause of preventable childhood blindness in the developing world and a contributing factor in chronic dry eye and night blindness.
How It Works
Vitamin A is metabolised to 11-cis-retinal, the chromophore in retinal photoreceptors essential for converting light into nerve signals. It is also required for epithelial cell differentiation, including the conjunctival goblet cells that produce tear-film mucin. Deficiency causes night blindness (rhodopsin failure), Bitot’s spots, conjunctival xerosis, corneal xerosis, and ultimately keratomalacia — a sight-threatening corneal melt.
Indications
- Vitamin A deficiency — confirmed by serum retinol or clinical features (night blindness, Bitot’s spots)
- Xerophthalmia — vitamin-A-deficiency-related dry eye and corneal disease
- Night blindness due to deficiency (not retinitis pigmentosa or other inherited disorders)
- Post-bariatric surgery deficiency
- Malabsorption syndromes (cystic fibrosis, biliary cirrhosis, short-bowel syndrome)
- Measles in children in endemic regions (WHO recommendation)
Dosing
Adults: 50,000–200,000 IU once daily for limited deficiency-correction courses (typically 1–2 weeks), then maintenance 5,000–10,000 IU daily. Children: weight-based dosing under paediatric supervision. Always under medical guidance — chronic high doses cause hypervitaminosis A.
Side Effects
At therapeutic doses: generally well tolerated.
Hypervitaminosis A (chronic high-dose): headache, nausea, blurred vision, dry skin, cracked lips, alopecia, bone pain, hepatotoxicity, raised intracranial pressure (pseudotumor cerebri).
Acute toxicity: nausea, vomiting, headache, dizziness, blurred vision — usually resolves within 24–48 hours after stopping.
Warnings & Contraindications
- Pregnancy — therapeutic-dose vitamin A is teratogenic; avoid
- Hepatic disease — vitamin A is stored in the liver; toxicity worsens with cirrhosis
- Concurrent isotretinoin or other retinoids — additive toxicity
- Hypervitaminosis A — additive risk
- Children — paediatric weight-based dosing only
Storage
Store at room temperature 15–25°C protected from moisture and light. Keep out of reach of children — high-dose vitamin A can cause acute toxicity in small bodies.
Frequently Asked Questions
Who needs Vitamin A supplementation?
People with confirmed deficiency (serum retinol or clinical features), xerophthalmia, post-bariatric or post-malabsorption patients, and children in endemic deficiency regions. Most healthy adults on a balanced diet do not need high-dose supplements.
Is more vitamin A better for night vision?
Only if you are deficient. Adding vitamin A to normal levels does not improve night vision and chronic excess causes toxicity (headache, hair loss, bone pain, hepatotoxicity).
Can Vitamin A Chewable Tablet be taken in pregnancy?
No — therapeutic-dose vitamin A is teratogenic. Routine prenatal vitamins contain low-dose vitamin A or beta-carotene (a safer precursor). Check the label and discuss any supplement with your obstetrician.
What is xerophthalmia?
The clinical syndrome of vitamin-A-deficiency dry eye — conjunctival xerosis, Bitot’s spots (foamy patches on the conjunctiva), corneal xerosis, and in severe deficiency keratomalacia (corneal melt). Reversible if treated early.
What is the difference between vitamin A and beta-carotene?
Vitamin A (retinol) is the active form; beta-carotene is a plant-based precursor that the body converts to vitamin A as needed. Beta-carotene cannot cause hypervitaminosis A — the body regulates conversion. Beta-carotene supplements are safer in pregnancy and chronic use.
What if I have liver disease?
Vitamin A is stored in the liver. Cirrhosis or any chronic liver disease increases toxicity risk. Routine high-dose supplementation is contraindicated. Mild deficiency can be addressed with dietary measures (orange and dark-green vegetables, dairy, eggs) plus low-dose multivitamins.
Is Vitamin A Chewable Tablet a treatment for retinitis pigmentosa?
Some studies suggest high-dose vitamin A palmitate (15,000 IU/day) may slow progression in adult-onset retinitis pigmentosa, but the evidence is mixed. This is not the same as treating routine night blindness. Discuss with a retinal specialist.
What about smokers?
Beta-carotene supplements (and possibly high-dose vitamin A) have been linked to increased lung cancer risk in smokers (CARET, ATBC trials). Smokers should avoid high-dose vitamin A and beta-carotene.
Can children take Vitamin A Chewable Tablet?
Only under paediatric guidance. Children are particularly susceptible to acute and chronic toxicity. WHO recommends specific doses for measles in children in endemic regions.
What if I take other multivitamins?
Check the total vitamin A content across all your supplements. Most multivitamins contain 2,500–5,000 IU. Adding Vitamin A Chewable Tablet on top can quickly exceed safe upper limits with chronic use.
