What should I know about prenatal vitamins with zinc before using them?

You should take only as much of this prenatal vitamin as your doctor prescribes each day. Also, do not take other multivitamins in addition to these without first consulting your doctor, as an excess of certain minerals or vitamins can cause severe reactions or fetal damage. If you are supposed to take other vitamins, space them two hours apart from your prenatal vitamin with zinc to avoid these reactions. Calcium may interfere with your body's absorption of prenatal vitamins, so avoid foods, medications, or supplements high in calcium around the time you take your prenatal vitamin.

Other drugs may interact with your vitamins, including:
  • diuretics
  • nonsteroidal anti-inflammatory drugs
  • heart medications
  • trimethoprim
  • blood pressure medications
  • sulfamethoxazole
  • isotretinoin
  • tretinoin
Talk to your doctor about all your medications and supplements before using prenatal vitamins. As with all medications and vitamins, make sure you keep these in a place children cannot reach them; they are more at risk for the same side effects that could affect you and your fetus.

Lastly, you should talk to your doctor about any conditions you have or have had in the past before taking prenatal vitamins with zinc.
