Novazinc is a combined ascorbic acid (vitamin C) + zinc supplement often used to support immune function, correct or prevent zinc deficiency, and act as an antioxidant. The “10 mg / 20 mg” likely refer to the zinc component strength. 

Over-the-counter (OTC) in many markets (nutritional supplement). Some pharmacies list Novazinc 20 mg tab available without prescription. 

Nutritional supplement / vitamin & mineral (antioxidant + trace element)

One listing (FDA Philippines) shows Ascorbic Acid + Zinc  500 mg (ascorbic acid) / 10 mg (zinc) capsule formulation. 

The 20 mg variant likely doubles the zinc dose from that base formulation.

The Pharmanova GH page lists “Novazinc · Vitamin-C · …” among products. 

• 10 mg zinc strength (with ascorbic acid)
•  20 mg zinc strength
•  Possibly different brand packaging or tablet vs capsule forms
•  The product appears in Ghanaian pharmacy listings as “Novazinc 20mg Tab” OTC. 

Oral (tablet or capsule)

Use as a supplement — typical direction would be 1 tablet daily or as advised by a healthcare provider. (Because it is a supplement, dosage depends on local guidelines and individual needs.)

One listing in the Philippines shows “Ascorbic Acid + Zinc (Novazinc) 500 mg / 10 mg – 1 capsule.” 

•  Gastrointestinal upset (nausea, diarrhea, abdominal cramps)
•  Metallic taste
•  Possible interference with absorption of other minerals (e.g. copper) when used long term
•  Rare allergic reactions

Safety Advice:

• Do not exceed recommended dose
•  Use cautiously in individuals with kidney disease
•  May interact with absorption of antibiotics (zinc can interfere with tetracyclines and quinolones) 
•  Long-term high-dose zinc may lead to copper deficiency
•  Not a substitute for a balanced diet
•  Pregnant or breastfeeding women should consult a physician
•  Use of vitamin C in high doses may cause gastric discomfort or diarrhea
