Pregnancy Home > Prenate DHA Side Effects

Insomnia, nausea, and headaches are among the possible Prenate DHA side effects (based on the reported side effects of the individual components of Prenate DHA). Although most people tolerate the prenatal vitamins well, serious side effects are possible. Notify your healthcare provider right away if you develop any unusual or unexplained bruising or bleeding, signs of an allergic reaction, or severe nausea or vomiting.

An Introduction to Prenate DHA Side Effects

As with any medicine, side effects are possible with Prenate DHA® prenatal vitamins. However, not everyone who takes the vitamins will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Prenate DHA. Your healthcare provider can discuss a more complete list of Prenate DHA side effects with you.)

Possible Side Effects of Prenate DHA

Prenatal vitamins do not need the approval of the Food and Drug Administration (FDA), and they are usually not studied as thoroughly as other types of medications. Therefore, detailed information about the possible side effects of prenatal vitamins is not available. However, based on the reported side effects of the individual components of Prenate DHA, the following side effects are possible:
  • Insomnia
  • Fatigue
  • Heartburn or indigestion
  • Diarrhea or constipation
  • Nausea and vomiting
  • Gas or belching
  • Intestinal cramps
  • Muscle aches and pains
  • Metallic taste in the mouth
  • Ringing in the ears (tinnitus)
  • Headaches
  • Yellow-orange discoloration of the urine
  • Loss of appetite.
In addition, because it contains fish oil, Prenate DHA may cause a fishy aftertaste or fishy burps.
As you can see, many of the possible Prenate DHA side effects are also some of the common aches, pains, and annoyances that are common during pregnancy. Therefore, it can be difficult to tell if a particular side effect is caused by Prenate DHA or by the pregnancy itself.
