    • This vitamin is used to aid the diet needs of a pregnant woman or one trying to get pregnant.
    • Most prenatal vitamins have more folic acid, iron, and calcium than normal adult multivitamins. Taking folic acid before the pregnancy and during the first 12 weeks may help stop some birth defects. A prenatal multivitamin will help you get needed nutrients in your diet.


    How to take

    • Take this vitamin with or without food. Take with food or at bedtime if it causes an upset stomach.
    • Follow the diet and workout plan that your doctor told you about.
    • If you are in your first 12 weeks of your pregnancy, you may want to take a prenatal vitamin without extra iron. Iron may cause hard stools (constipation) and upset stomach. Extra iron is most often needed in the second and third trimesters.

    Missed Dose

    • Take a missed dose as soon as you think about it.
    • If it is close to the time for your next dose, skip the missed dose and go back to your normal time.
    • Do not take 2 doses at the same time or extra doses.
    • Do not change the dose or stop this drug. Talk with the doctor.


    • Store at room temperature.
    • Protect from water. Do not store in a bathroom or kitchen.



    • Keep away from children. Poisonings with iron happen most often in children. First signs of overdose include feeling tired, upset stomach, throwing up, belly pain, dark tarry-black stool, and a weak or fast heartbeat.


    • Tell your doctor if you are allergic to any drugs. Make sure to tell about the allergy and what signs you had. This includes telling about rash; hives; itching; shortness of breath; wheezing; cough; swelling of face, lips, tongue, or throat; or any other signs.


    • Keep a list of all your drugs (prescription, natural products, vitamins, OTC) with you. Give this list to your doctor.
    • Check all drugs you are taking with your doctor. This drug may not mix well with some other drugs.
    • If you have a baby with a birth defect, talk with your doctor before trying to get pregnant. You may need even higher doses of folic acid.

    Side Effects

    • Upset stomach or throwing up. Many small meals, good mouth care, sucking hard, sugar-free candy, or chewing sugar-free gum may help.
    • Hard stools (constipation). Drinking more liquids, working out, or adding fiber to your diet may help. Talk with your doctor about a stool softener or laxative.
    • Loose stools (diarrhea).
    • Belly pain.

    Contact a healthcare provider

    • If you think there was an overdose, call your local poison control center or ER right away.
    • Signs of a very bad reaction to the drug. These include wheezing; chest tightness; fever; itching; bad cough; blue or gray skin color; seizures; or swelling of face, lips, tongue, or throat.
    • Very upset stomach or throwing up.
    • Want to stop taking prenatal multivitamin, mostly during first 12 weeks of your pregnancy.
    • Side effect or health problem is not better or you are feeling worse.
