How to take this drug

For general supplementation, take 1 tablet (100–500 mg) once or twice daily. For Vitamin C deficiency, your doctor may recommend up to 1000 mg daily. You can take it with or without food, but taking it with food helps reduce stomach upset. Popular brands in Nigeria include Ascorvit Chewable Tablets, Bioracee Tablets, and Alben Vitamin C 1000 mg Caplet.

What if I Miss a Dose?

If you miss a dose, just take it when you remember. If it's almost time for your next dose, skip the missed one and continue as normal. No need to double up.

What to watch out for

Buy from reputable pharmacies and check the NAFDAC number — avoid buying from roadside sellers or open markets where storage conditions are poor. Do not take mega-doses thinking more is better — your body only needs a certain amount and the rest is wasted or can cause side effects. If you are managing sickle cell disease, speak to your doctor before starting Vitamin C supplements.

Common Side Effects

Stomach upset or mild belly pain
diarrhea or loose stool (especially with high doses)
nausea
heartburn
headache

Serious Side Effects

Kidney stones (sharp pain in your lower back or side
blood in urine) — especially with very high doses over a long time. Severe allergic reaction such as swelling of the face
difficulty breathing
or rash — stop taking it and go to the hospital immediately.

Drug Interactions

Taking Vitamin C together with iron supplements increases how much iron your body absorbs, which can be helpful but also harmful if you already have too much iron. High doses of Vitamin C can affect how well blood-thinning drugs like warfarin work. If you are taking aluminium-containing antacids, avoid taking high-dose Vitamin C at the same time as it can increase aluminium absorption.

Pregnancy & Breastfeeding Warning

Vitamin C is generally safe during pregnancy and breastfeeding at normal recommended doses, but avoid taking very high doses — consult your doctor before use.

Who Should NOT Take This

People who are allergic to ascorbic acid or any ingredient in the product. People with a history of kidney stones should avoid high doses. People with conditions that cause iron overload (like sickle cell disease or haemochromatosis) should consult a doctor before taking Vitamin C supplements.

How to Store

Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can spoil vitamins quickly. Keep the container tightly closed and away from children. Do not store in the bathroom or near a window.
