Description

Overview of the medicine

C-Rich 250 mg Chewable Tablet is a vitamin C supplement used to prevent or treat low levels of vitamin C in people who do not get enough of the vitamin from their diets. It is essential for immune function, collagen formation, and as an antioxidant.

Uses & Indications

Prevention and treatment of Vitamin C deficiency (scurvy)

Support immune function

Adjunctive therapy for wound healing and tissue repair

As an antioxidant to reduce oxidative stress

Dosage

Adults

For deficiency: 250-500 mg daily. For general health/supplementation: 250 mg daily.

Elderly

Same as adult dosage, usually 250 mg daily.

Renal_impairment

Generally safe, but high doses (over 1g/day) should be avoided in severe renal impairment due to potential risk of oxalate stone formation.

How to Take

Chew or allow the tablet to dissolve in the mouth. Can be taken with or without food. For best absorption, it is often recommended to take with a meal.

Mechanism of Action

Vitamin C is an essential nutrient involved in the repair of tissue and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function, collagen synthesis, and acts as a powerful antioxidant.

Pharmacokinetics

Onset

Effects are gradual with regular intake; acute effects are not typically seen with supplementation.

Excretion

Excreted renally (via kidneys) as unchanged ascorbic acid and its metabolites. Excess amounts are rapidly excreted in urine.

Half life

Approximately 10-20 days, depending on body stores and dose. When stores are saturated, half-life is shorter (around 30 minutes).

Absorption

Readily absorbed from the gastrointestinal tract, primarily in the small intestine, by an active transport mechanism. Absorption is dose-dependent and saturable at high doses.

Metabolism

Partially metabolized to inactive compounds, mainly oxalic acid and ascorbate-2-sulfate, in the liver and other tissues.

Side Effects

Contraindications

Hypersensitivity to ascorbic acid or any component of the formulation.
Severe hyperoxaluria or a history of oxalate kidney stones (especially with high doses).
Glucose-6-phosphate dehydrogenase (G6PD) deficiency (high doses).

Drug Interactions

Warfarin

High doses of Vitamin C may decrease the anticoagulant effect of warfarin.

Desferrioxamine

Concomitant use with high doses of Vitamin C may increase cardiac toxicity in iron overload.

Iron supplements

Vitamin C enhances the absorption of non-heme iron. While often beneficial for iron deficiency, it should be considered if iron levels are already high.

Aluminum-containing antacids

Vitamin C can increase the absorption of aluminum, especially in patients with kidney problems.

Storage

Store in a cool, dry place (below 30°C), away from direct sunlight and moisture. Keep out of reach of children.

Overdose

Overdose is rare due to the water-soluble nature of vitamin C. Symptoms may include gastrointestinal upset (diarrhea, nausea, abdominal cramps). Management is symptomatic and supportive; reducing the dose or discontinuing the supplement usually resolves symptoms.

Pregnancy & Lactation

Generally considered safe for use during pregnancy and lactation at recommended dosages. Consult a doctor before taking doses significantly higher than the recommended daily allowance.
