Other medications andHidroferol0.1 mg/ml oral drops in solution

Inform your doctor or pharmacist if you are using, have recently used, or may need to use any other medication, including those purchased without a prescription.

Some medications may affect how this medication works. On the other hand, the active ingredient, calcifediol monohydrate, may affect the efficacy of other medications taken at the same time.

Therefore, interactions may occur with the following medications:

  • Medications used to treat epilepsy (such as phenytoin, phenobarbital, and primidone) and other enzyme-inducing medications (which may decrease the effect of Hidroferol).
  • Medications for the heart and/or hypertension, such as cardiac glycosides, thiazide diuretics, or verapamil.
  • Colestyramine, colestipol (for cholesterol), orlistat (for obesity): the administration of these medications and calcifediol should be separated by at least 2 hours.
  • Mineral oil or paraffin (laxatives): it is recommended to use another type of laxative or separate the administration of both medications.
  • Some antibiotics (such as penicillin, neomycin, and chloramphenicol).
  • Magnesium salts.
  • Other products containing vitamin D.
  • Calcium supplements.
  • Corticosteroids (anti-inflammatory medications).

Taking Hidroferol 0.1 mg/ml oral drops in solution with food and beverages

Some foods and beverages are supplemented with vitamin D. This should be taken into account, as the effects of these foods may be added to the effects of this medication and become excessive.

Pregnancy, breastfeeding, and fertility

This medication will only be used during pregnancy if the vitamin D deficiency has been clinically diagnosed.

Hidroferol can be used during breastfeeding.

Calcifediol passes into breast milk. This should be considered when administering additional vitamin D to the breastfed infant.

There are no data on the effects of calcifediol on fertility. However, it is not expected that normal vitamin D levels will have adverse effects on fertility.

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Adults

  • Treatment and prevention of vitamin D deficiency in patients with identified risks: 1 to 3 drops of calcifediol in solution per day.
  • As a complement to medication for bone loss: 1 to 3 drops per day.
