Ask your doctor before using any vitamin or mineral supplement, or an antacid. Use only the type of antacid or supplements that your doctor recommends. Some minerals or antacids can make it harder for your body to absorb ferrous gluconate.
Avoid taking antacids or antibiotics within 2 hours before or 2 hours after taking ferrous gluconate. This is especially important if you take:
ciprofloxacin, levofloxacin, lomefloxacin, norfloxacin, ofloxacin; or
demeclocycline, doxycycline, minocycline, or tetracycline.
Certain foods can also make it harder for your body to absorb ferrous gluconate. Avoid taking this medicine within 1 hour before or 2 hours after eating fish, meat, liver, and whole grain or "fortified" breads or cereals.
