Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Slonce D3 Drops contains Cholecalciferol (Vitamin D3) (strength not specified). It belongs to the Vitamin D analogue (Cholecalciferol) class of medicines.
Vitamin D3 (cholecalciferol) is converted in the body to active vitamin D, which increases intestinal absorption of calcium and phosphate. This helps maintain normal blood calcium levels and supports bone mineralization and skeletal health.
Oral drops. Shake well before use. Measure the prescribed dose using a calibrated dropper and administer directly or mix with a small amount of milk/water. Can be taken with or without food; follow doctor’s advised dose and duration (especially for infants/children).
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
An overdose of this medicine can raise blood calcium dangerously, causing thirst, frequent urination, vomiting, confusion and kidney damage. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Slonce 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.

Do not exceed recommended dose. Use with caution in hypercalcemia, hypervitaminosis D, kidney stones, severe kidney disease, and sarcoidosis or other granulomatous disorders. Prolonged high doses can cause vitamin D toxicity (hypercalcemia) with symptoms like weakness, confusion, vomiting, excessive thirst/urination—seek medical help. Check with doctor if taking other vitamin D or calcium supplements.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with a high blood calcium level, or with certain kidney stones.
Thiazide diuretics (e.g., hydrochlorothiazide), digoxin and other cardiac glycosides, anticonvulsants (phenytoin, phenobarbital, carbamazepine), rifampicin, corticosteroids, cholestyramine/orlistat (reduced absorption), aluminum/magnesium antacids (especially in renal impairment)
Store at room temperature (below 25°C), protected from light and moisture. Keep bottle tightly closed. Keep out of reach of children.
Take calcium with food, and split the day's total if you take a large amount. Sunlight helps your body make its own vitamin D. Have your level rechecked as your doctor advises rather than continuing high doses indefinitely.
