What Should I Tell My Healthcare Provider?

You should talk with your healthcare provider prior to taking Nestabs® if you have:
  • Anemia
  • Any allergies, including to foods, dyes, or preservatives.
Also, let your healthcare provider know if you are breastfeeding.
You should also tell your healthcare provider about all other medications you are taking, including prescription and nonprescription medicines, vitamins, and herbal supplements.

Specific Precautions and Warnings With Nestabs

Some warnings and precautions to be aware of prior to taking this prenatal vitamin include the following:
  • Nestabs contains doses of folic acid that could mask certain types of anemia. This means it is difficult to determine if you have anemia from simple blood tests. If you do have anemia, talk to your healthcare provider before starting Nestabs. He or she may choose to test you for this condition before you start taking this prenatal vitamin.
  • The iron found in Nestabs can be fatal if consumed in large amounts by a child. In fact, iron poisoning is one of the leading causes of poisoning deaths in children under six years old. Keep this and all medicines out of the reach of children. Seek immediate medical help if a child, or anyone, may have taken too much Nestabs (see Nestabs Overdose).
  • The calcium in Nestabs is in the form of calcium formate. Formate, if taken in large doses, can cause vision problems. Although the amount of formate found in Nestabs is extremely unlikely to cause a problem, you should let your healthcare provider know if you experience any vision changes while taking this product.
  • This product is usually considered safe, and is often recommended, for use in women who are nursing. Talk to your healthcare provider about taking prenatal vitamins if you are breastfeeding a child (see Nestabs and Breastfeeding).
