Avoid taking any other multivitamin or mineral product within 2 hours before or after you take ferrous sulfate. Taking similar mineral products together the same time can result in a mineral overdose or serious side effects.

Avoid taking an antibiotic medicine within 2 hours before or after you take ferrous sulfate. This is especially important if you are taking an antibiotic such as ciprofloxacin (Cipro), demeclocycline (Declomycin), doxycycline (Adoxa, Doryx, Oracea, Vibramycin), levofloxacin (Levaquin), minocycline (Dynacin, Minocin, Solodyn, Vectrin), norfloxacin (Noroxin), ofloxacin (Floxin), or tetracycline (Brodspec, Panmycin, Sumycin, Tetracap).

Certain foods can also make it harder for your body to absorb ferrous sulfate. Avoid taking this medication within 1 hour before or 2 hours after eating fish, meat, liver, and whole grain or "fortified" breads or cereals.

Avoid using antacids without your doctor's advice. Use only the specific type of antacid your doctor recommends. Antacids contain different medicines and some types can make it harder for your body to absorb ferrous sulfate.
