Reduce Side Effects
A recent study showed that taking calcium carbonate and gemifloxacin at the same time results in a significant reduction in blood levels of the drug.1 Consequently, gemifloxacin and calcium supplements should not be taken at the same time.
A review of interactions involving quinolone antibiotics indicated that supplements containing iron, when taken at the same time as gemifloxacin, might reduce absorption of the drug up to 50%.2 Consequently, gemifloxacin and supplements containing iron should not be taken at the same time.
One study showed that taking an antacid containing magnesium and aluminum ten minutes before gemifloxacin results in an 85% reduction in the absorption of the drug.3 Consequently, gemifloxacin and supplements containing magnesium should not be taken at the same time.
