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.

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.
