1. What is Mastical D Unidia and what is it used for

Mastical D Unidia are chewable tablets that contain calcium and vitamin D3, both of which are important for bone formation. Mastical D Unidia is used in the prevention and treatment of calcium and vitamin D deficiency in adults with associated risk of calcium and vitamin D deficiency and as a supplement to specific osteoporosis treatment.

2. What you need to know before taking Mastical D Unidia

Do not take Mastical D Unidia

  • if you are allergic to calcium, vitamin D, or any of the components of this medicine (listed in section 6).
  • if you have severe kidney problems.
  • if you have excessive calcium in the blood or urine.
  • if you have kidney stones.
  • if you have excessive vitamin D in the blood.

Warnings and precautions

Consult your doctor or pharmacist before taking Mastical D Unidia:

  • if you are undergoing long-term treatment, especially if you are taking diuretics (used to treat high blood pressure or edema) or cardiac glycosides (used to treat heart conditions).
  • if you have signs of altered renal function or tendency to form kidney stones.
  • if you have sarcoidosis (an immune system disorder that can increase vitamin D levels in the body).
  • if you have osteoporosis and are unable to move around.
  • if you are taking other products containing vitamin D. Additional doses of calcium and vitamin D should be taken under strict medical supervision.

Children and adolescents

Mastical D Unidia is not indicated for use in children and adolescents.

Taking Mastical D Unidia with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

If you are also taking tetracyclines (a type of antibiotic), take them at least 2 hours before or 4-6 hours after taking Mastical D. Calcium carbonate may interfere with the absorption of tetracycline preparations if taken at the same time.

Medicines containing bisphosphonates (used to treat osteoporosis) should be taken at least 1 hour before taking Mastical D Unidia.

Calcium may reduce the effect of levothyroxine (used to treat thyroid hormone deficiency). Therefore, levothyroxine should be taken at least 4 hours before or 4 hours after taking Mastical D Unidia.

The effects of quinolone-based antibiotics may be reduced if taken at the same time as calcium. Take quinolone-based antibiotics 2 hours before or 6 hours after taking Mastical D Unidia.

Calcium salts may decrease the absorption of iron, zinc, and strontium ranelate. Therefore, iron, zinc, or strontium ranelate preparations should be taken at least 2 hours before or after Mastical D Unidia.

Other medicines that may interact with or be affected by Mastical D Unidia are:

  • thiazide diuretics (used to treat hypertension or edema)
  • cardiac glycosides (used to treat heart conditions)

Orlistat (used to treat obesity) may alter the absorption of fat-soluble vitamins, such as vitamin D3.

If you are using any of the mentioned medicines, your doctor will provide more instructions.

Taking Mastical D Unidia with food and drinks

Mastical D Unidia can be taken with or without food and drinks.

Pregnancy, breastfeeding, and fertility

If you are pregnant, you can use Mastical D Unidia in case of calcium and vitamin D deficiency. During pregnancy, do not take more than 2500 mg of calcium and 4000 IU of vitamin D per day, as overdoses can affect the fetus.

Mastical D Unidia can be taken during breastfeeding. Calcium and vitamin D3 pass into breast milk. This should be taken into account when administering additional vitamin D to the child.
