O.n.w D3 Capsule is used for treatment and prevention of vitamin D deficiency, adjunct in calcium deficiency and bone health disorders such as osteopenia/osteoporosis, supportive therapy in rickets/osteomalacia (as advised).
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Vitamin D3 (cholecalciferol) is converted in the body to active vitamin D, which increases absorption of calcium and phosphate from the intestine. It helps maintain normal blood calcium levels and supports bone mineralization and muscle function.
Capsule for oral use. Take as prescribed by the doctor; commonly taken once weekly or once monthly depending on strength and deficiency status. Swallow whole with water, preferably after food (fat-containing meal improves absorption). Do not exceed the recommended dose.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take the missed dose of O.n.w D3 as soon as you remember. If it is almost time for the next dose, skip the missed one and carry on with the usual schedule. Do not take two doses together to make up for a missed dose.
Taking more O.n.w D3 than prescribed can be harmful. If you suspect an overdose, contact a doctor or go to the nearest emergency department at once, and carry the pack or strip with you. In India the emergency number is 112.
Most side effects of O.n.w D3 are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Use with caution in kidney disease, kidney stones, hypercalcemia, hypervitaminosis D, sarcoidosis or other granulomatous disorders. Excess vitamin D can cause high calcium levels; monitor serum calcium/25(OH)D if on high-dose or long-term therapy. Consult a doctor before use in children, elderly, or if taking calcium supplements. Seek medical help if symptoms of hypercalcemia occur (persistent nausea/vomiting, confusion, severe weakness, palpitations).
Thiazide diuretics (may increase risk of hypercalcemia), digoxin/cardiac glycosides (arrhythmia risk with hypercalcemia), antiepileptics like phenytoin/phenobarbital/carbamazepine (reduced vitamin D effect), glucocorticoids (reduced effect), cholestyramine/orlistat (reduced absorption), aluminum- or magnesium-containing antacids with prolonged use (caution in renal impairment)
Store at room temperature (below 25°C), protected from light and moisture. Keep in original blister/strip. Keep out of reach of children.
