Used for Prenatal Vitamin

Prenatal vitamins are combination vitamins and minerals that are taken before, during, and sometimes after, pregnancy. They're important for a healthy pregnancy and for helping the baby grow and develop. Prenatal vitamins come in different forms, such as tablets, liquid, and chewable gummies. Some are available over the counter, while others are prescription only. Not all prenatal vitamins contain the same ingredients, so it's important that you read the labels carefully. Side effects of prenatal vitamins can include nausea or constipation and you're more likely to experience them if your product contains iron.

Pharmacist tips for Prenatal vitamins

pharmacist

  • In addition to eating healthy, a prenatal vitamin can help supply all of the nutrition you need to support you and your baby during pregnancy. But everyone has different nutritional needs, so talk with your provider about the best supplement choice for you.

    • Tell your provider or pharmacist about all the medications and dietary supplements you're taking before starting prenatal vitamins to make sure there are no interactions.

      • Don't take other vitamins or supplements while you're taking a prenatal vitamin without checking with your provider first. Many of the ingredients found in prenatal vitamins are also in other prescription and over-the-counter products. Taking too much of certain ingredients (e.g., vitamin A) can lead to side effects and harm to your baby.

        • Most prenatal vitamins can be taken with or without food. Make sure to read the directions on the package.

          • Ask your provider if you need to continue taking prenatal vitamins after you give birth. You might not need to continue this supplement, especially if you're already getting enough nutrients through foods.

            • Store prenatal vitamins at room temperature and away from children. If your child accidentally took prenatal vitamins, get medical help or call the Poison Control Center at 1-800-222-1222 right away.

              • Some prenatal vitamins are available over-the-counter, while others are only available with a prescription from your provider. Your provider might recommend a specific product for you, depending on your unique nutritional needs.

                Frequently asked questions about Prenatal vitamins

                Can you take prenatal vitamins without being pregnant?
                You can. In fact, if you're planning to get pregnant, it's best to start taking a prenatal vitamin before you conceive. But if you don't have plans to get pregnant, a general multivitamin might be enough for you. Ask your provider if you're not sure whether you need to take a multivitamin.
                When to start taking prenatal vitamins?
                Providers typically recommend that you start taking a prenatal vitamin 1 to 3 months before you become pregnant. The nutrients in a prenatal vitamin, such as folic acid, are important for a growing baby, especially in the early stages of development. So if you're thinking about starting a family, you can start taking a prenatal vitamin right away, without waiting until you're pregnant.
                When is it too late to start taking prenatal vitamins?
                If you're pregnant, it's never "too late" to start taking prenatal vitamins, but earlier is better. This is because fetus development is critical in the first few weeks of pregnancy; the brain and spinal cord have already started to develop. For this reason, it's ideal to start taking a prenatal vitamin before you conceive. Baby development continues throughout your pregnancy, so if you haven't been taking a prenatal vitamin, start taking one and talk with your provider about your baby's health.
                Do prenatal vitamins help you get pregnant?
                More research is needed to understand how the different vitamins and minerals impact fertility. But existing research suggests that taking enough folic acid can help with fertility. In addition, prenatal vitamins might lower the risk of miscarriage. In general, providers recommend a balanced diet that includes foods such as whole grain, fruits, and vegetables for people who are trying to conceive.
                Can men take prenatal vitamins?
                Yes, men can take prenatal vitamins. But keep in mind that prenatal vitamins contain specific nutrients that support pregnancy and growing babies. Males have different nutritional needs than pregnant females, and there are other multivitamins that might be better suited for their daily requirements.
                Can prenatal vitamins make you sick?
                Some people can experience nausea, bloating, and constipation from taking prenatal vitamins. You're more likely to experience these side effects if your prenatal vitamin contains iron. If you feel sick from your prenatal vitamin, let your provider know. They can recommend ways to help, depending on what symptoms you're experiencing. For example, they might ask you to try taking your prenatal vitamin with food or changing the formulation (e.g., trying a liquid or chewable gummy).
                Do prenatal vitamins help hair grow?
                There's not much research looking at how prenatal vitamins might affect hair growth. Limited studies suggest that certain vitamins that are found in prenatal vitamins, like vitamin D, iron, and zinc, might promote hair growth or prevent hair loss. But you shouldn't take prenatal vitamins just for this purpose.
                Do prenatal vitamins have iron?
                Not all prenatal vitamins have iron so make sure to check the label of your specific product. While having enough iron is important for a healthy pregnancy, not everyone needs an iron supplement. Iron is found in many foods (e.g., beans, beef, shrimp) and many people get enough iron through their diet. If you're pregnant, your provider will order blood work to check if you've anemia from low iron levels. If so, they'll likely recommended that you take a prenatal vitamin that contains iron.

                What are the risks and warnings for Prenatal vitamins?

                Prenatal vitamins can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

                risk-warning

                Iron overdose

                Some prenatal vitamins contain iron, which is also in many over-the-counter products. Taking too much iron can lead to serious side effects, including nausea, vomiting, diarrhea, and stomach pain. Tell your provider or pharmacist all the medications and supplements you're taking so they can make sure you aren't taking too much iron.

                Also, keep this medication out of reach of children. Accidental overdose of iron-containing products is a leading cause of death from poisoning in children. If you think a child accidentally took a prenatal vitamins product that contains iron, get medical help or call a Poison Control Center at 1-800-222-1222 right away.

                risk-warning

                Potential to hide anemia due to low vitamin B12

                Prenatal vitamins contain folic acid. Taking folic acid can sometimes hide signs of a condition called pernicious anemia, which is a type of anemia due to low vitamin B12 levels. If you have a history of low vitamin B12 levels, let your healthcare provider know.
