VCZ-500 CHEWABLE TAB SL/ST
VITAMIN C + ZINC CHEWABLE
VCZ-500 CHEWABLE TAB SL/ST is a chewable tablet of vitamin C with zinc. It is used as a supplement during colds and respiratory infections, in convalescence, for wound healing, and where dietary intake of either nutrient is inadequate.
01
Benefits
- Vitamin C is required for collagen formation, wound healing and normal immune function, and is not stored by the body.
- Zinc supports immune function, wound healing and taste perception, all of which are impaired in deficiency.
- Zinc taken early in a cold may modestly shorten its duration.
- Vitamin C enhances the absorption of dietary iron, useful alongside iron supplementation.
- The chewable format needs no water and suits patients who dislike swallowing tablets.
02

Common

- Abdominal cramping
Less common
- Heartburn

Stop and get medical help if any of these occur
- Loin pain or blood in the urine, as high-dose vitamin C can promote oxalate kidney stones
- Persistent vomiting or severe abdominal pain
- Swelling of the face, lips or tongue, or difficulty breathing
- Widespread rash or hives
- Persistent diarrhoea with weakness
03
Precautions
- High-dose vitamin C increases the risk of oxalate kidney stones. Use with caution in a history of stones and in renal impairment.
- Prolonged high-dose zinc causes copper deficiency and can impair immune function — do not continue high doses indefinitely.
- Contraindicated in haemochromatosis and in glucose-6-phosphate dehydrogenase deficiency, where high-dose vitamin C can cause haemolysis.
- Zinc impairs absorption of tetracycline and fluoroquinolone antibiotics — separate doses by at least two hours.
- Take with or after food to reduce nausea, and rinse the mouth after chewing to protect tooth enamel.
- High-dose vitamin C can interfere with blood glucose meter readings and with faecal occult blood tests.
- A supplement, not a treatment for infection. It does not replace assessment of a persistent or severe illness.
