Some prenatal multivitamins may affect other medical conditions or treatments. Do not start taking a prenatal multivitamin without first talking to your doctor if you have other health problems or conditions, or if you take other medications.
Prenatal multivitamins are generally considered to be safe for use during pregnancy and breast-feeding. However, large doses of some vitamins can be harmful. Talk to your doctor or pharmacist about taking a prenatal vitamin during pregnancy or breast-feeding.
Take prenatal multivitamins exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.
Take each dose with a full glass of water.
Prenatal multivitamins may be taken on an empty stomach or with food, which may lessen stomach upset.
Chewable tablet formulations of prenatal multivitamins should be chewed thoroughly before swallowing.
To ensure that you get the correct dosage, measure the liquid forms of prenatal multivitamins with a dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one.
Do not take more of a prenatal vitamin than is prescribed or is directed on the package. Large doses of prenatal multivitamins can be dangerous.
It is important to take prenatal multivitamins regularly to get the most benefit.
Store prenatal multivitamins at room temperature away from moisture and heat.
Take the missed dose as soon as you remember. However, if it is almost time for the next dose, skip the missed dose and take only the next regularly scheduled dose. Do not take a double dose.
Stop taking prenatal multivitamins and seek emergency medical attention if you experience an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives).
Other, less serious side effects may be more likely to occur. Nausea, constipation, black stools, and diarrhea are among the most common. Taking prenatal multivitamins with food may decrease these side effects.
Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
Do not take more of a prenatal multivitamin than is prescribed or is directed on the package. Large doses of prenatal multivitamins can be dangerous.
There are no restrictions on food, beverages, or activities while taking a prenatal multivitamin, unless otherwise directed by your doctor.
Before taking a prenatal multivitamin, tell your doctor if you are taking any other prescription or over-the-counter medicines, including vitamins, minerals, and herbal products. You may not be able to take the prenatal multivitamin, or you may require a dosage adjustment or special monitoring if you are taking any other medicines.
Seek emergency medical attention if an overdose is suspected.
Most commonly, symptoms of a vitamin and mineral overdose include nausea and vomiting.
