An Introduction to Prenatal Vitamin Side Effects
As with any medicine, side effects are possible with
prenatal vitamins. However, not all women who take prenatal vitamins will experience side effects. In fact, most women tolerate them 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 prenatal vitamins. Your healthcare provider can discuss a more complete list of side effects with you.)
Possible Side Effects of Prenatal Vitamins
Because prenatal vitamins do not require FDA approval, they are usually not studied as thoroughly as other types of medications.
As a result, detailed information about the possible side effects of prenatal vitamins is not available. However, based on the side effects of the individual components of prenatal vitamins, the following side effects are possible:
- Headaches
- Intestinal cramps
- Constipation or diarrhea
- Indigestion or heartburn
- Muscle aches and pains
- Nausea and vomiting
- Fatigue
- Gas or belching
- Metallic taste
- Ringing in the ears (tinnitus)
- Insomnia
- Yellow-orange discoloration of the urine
- Loss of appetite.
As you can see, many of the possible prenatal vitamin side effects are also some of the aches, pains, and annoyances that are common during pregnancy. Therefore, it can be difficult to tell whether the prenatal vitamins (or the pregnancy itself) are causing a particular side effect.
