Doxykin Doxycycline Calcium acetate + Magnesium carbonate
ModerateCalcium acetate + magnesium carbonate can interfere with how well your body absorbs doxycycline. When they are taken together, less of the doxycycline may get into your body, so it may not work as well as it should.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
