Nestabs DHA Warnings and Precautions

While many pregnant and breastfeeding women may benefit from the vitamins and minerals found in Nestabs DHA, some women may not be able to safely use this prescription prenatal vitamin. Women who have anemia or a bleeding disorder should follow the safety precautions associated with Nestabs DHA, as there are specific warnings about dangerous complications that could occur.

What Should I Tell My Healthcare Provider?

You should talk with your healthcare provider prior to taking Nestabs® DHA if you have:
  • Anemia
  • A bleeding disorder
  • An allergy to fish
  • Any other 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 DHA

Some warnings and precautions to be aware of prior to taking this prenatal vitamin include the following:
  • Nestabs DHA contains folic acid, which can mask anemia due to vitamin B12 deficiency. This means it will be more difficult for your healthcare provider to determine if you have a vitamin B12 deficiency from simple blood tests. If you have anemia, talk to your healthcare provider before starting Nestabs DHA.
  • Nestabs DHA contains the omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). People who consume high doses of omega-3 fatty acids may have an increased risk for bleeding, including potentially dangerous internal bleeding.

Although this is not likely to be a problem with the doses of omega-3 fatty acids found in Nestabs DHA, you should let your healthcare provider know if you have a bleeding disorder, as this can make you more susceptible to this side effect. Also, tell your healthcare provider if you notice any unusual bleeding or bruising while taking this vitamin.

  • The omega-3 fatty acids in Nestabs DHA are derived from fish oil. This could be a problem for people who have a fish allergy.
  • Nestabs DHA contain iron, which can be fatal if consumed in large amounts by a child. Iron poisoning is one of the leading causes of poisoning deaths in children under six years old. It is important to keep this and all other vitamins out of the reach of children. Seek immediate medical help if a child, or anyone else, may have taken too much of this product (see Nestabs DHA Overdose).
  • The calcium in Nestabs DHA 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 DHA is unlikely to cause a problem, you should let your healthcare provider know if you experience changes in vision while taking this vitamin.
  • Nestabs DHA is usually considered safe, and often beneficial, for use in women who are nursing. Talk to your healthcare provider about taking prenatal vitamins if you are breastfeeding a child (see Nestabs DHA and Breastfeeding).
