Vitamin D analogue (Bone health supplement)
Last reviewed July 2026
Who is this for?
Calcifediol (sold as Hidroferol) is a form of vitamin D that your body can use more quickly than regular vitamin D supplements. It helps your body absorb calcium from food to keep your bones strong.
Activates the vitamin D receptor (VDR) in intestinal epithelium and bone cells, promoting intestinal calcium and phosphate absorption and enhancing bone mineralization to correct deficiency-related hypocalcemia and skeletal disorders. In chronic kidney disease, it bypasses impaired renal 1α-hydroxylase activity to provide active vitamin D metabolite directly.

If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not take two doses at once to make up for it.
Only use this drug if prescribed by a doctor. Do not self-medicate with it thinking it is the same as regular vitamin D supplements. Make sure to do the blood tests your doctor requests to check your calcium and vitamin D levels. Buy only from licensed pharmacies, not from roadside sellers or unverified online shops.
Thiazide water tablets (like hydrochlorothiazide) can cause dangerously high calcium levels when combined with calcifediol. Antacids containing magnesium should be avoided as they can cause problems. If you take heart drugs like digoxin, high calcium from this drug can make digoxin side effects worse, so tell your doctor about all medicines you are taking.
Check your specific combination
Is it safe to take Calcifediol with your other drugs?
Do not take calcifediol during pregnancy or while breastfeeding unless your doctor specifically prescribes it, as too much vitamin D can harm the baby.
Store in a cool, dry place away from direct sunlight and heat. Nigerian weather can be very hot, so do not leave it in your car or near a window. Keep it in its original container and far from children's reach.
