Missed dose and overdose

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.

Warnings and precautions

Do not take more than your doctor has advised. Vitamin D builds up in the body and too much raises blood calcium, causing thirst, frequent urination, nausea and confusion. High-dose weekly or monthly sachets are prescription strengths — do not repeat one because you missed a week. Tell your doctor if you have had kidney stones or have kidney disease.

Do not take Klm D3 Nano if

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.

Interactions with other medicines

Calcium reduces the absorption of thyroid tablets, several antibiotics and iron — separate them by a few hours. Water tablets of the thiazide group raise calcium further when combined.

How to store Klm D3 Nano Drops

Store below 30°C, away from direct sunlight. Do not freeze. Once opened, use it within the period printed on the pack. Keep out of the reach of children.

Expert advice for Klm D3 Nano Drops

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.
