    • Pharmacologic Category: Vitamin

    • This vitamin is used to supplement the nutritional needs of a pregnant female or one trying to get pregnant.
    • Most prenatal vitamins contain greater amounts of folic acid, iron, and calcium than standard adult multivitamins. Taking folic acid before the pregnancy and during the first 12 weeks can help prevent certain birth defects. The body is making so much extra blood that you need 3-4 times the usual amount of iron every day. A prenatal multivitamin will help you get enough essential 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 diet plan and exercise program as recommended by healthcare provider.
    • If you are in your first 12 weeks of pregnancy, you may want to take a prenatal vitamin without extra iron. Iron may cause constipation and upset stomach. Additional iron is most necessary in the second and third trimesters.

    Missed Dose

    • Take a missed dose as soon as possible.
    • If it is almost time for the next dose, skip the missed dose and return to your regular schedule.
    • Do not take a double dose or extra doses.
    • Do not change dose or stop medicine. Talk with healthcare provider.


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



    • Tell healthcare provider if you are allergic to any medicine. Make sure to tell about the allergy and how it affected you. This includes telling about rash; hives; itching; shortness of breath; wheezing; cough; swelling of face, lips, tongue, or throat; or any other symptoms involved.


    • Check medicines with healthcare provider. This medicine may not mix well with other medicines.
    • If you have a baby with a birth defect, talk with healthcare provider before trying to get pregnant. You may need even higher doses of folic acid.

    Side Effects

    • Nausea or vomiting. Small frequent meals, frequent mouth care, sucking hard, sugar-free candy, or chewing sugar-free gum may help.
    • Constipation. More liquids, regular exercise, or a fiber-containing diet may help. Talk with healthcare provider about a stool softener or laxative.


    • Change in condition being treated. Is it better, worse, or about the same?
    • Follow up with healthcare provider.

    Contact a healthcare provider

    • If you suspect an overdose, call your local poison control center or emergency department immediately.
    • Signs of a life-threatening reaction. These include wheezing; chest tightness; fever; itching; bad cough; blue skin color; fits; or swelling of face, lips, tongue, or throat.
    • Severe nausea or vomiting.
    • Desire to stop taking prenatal multivitamin, especially during first 12 weeks of pregnancy.
    • No improvement in condition or feeling worse.
