Prenaforte makes me vomit

Hi there. Was your doctor the one who prescribed Prenaforte? Best to check with her/him. The iron in prenatal vitamins may cause constipation, and some women complain of nausea. You also may have diarrhea, dark stools, low appetite, and stomach upset or cramps. Ask your doctor for recommendations. If your prenatal vitamin is still making you sick, your practitioner may be able to prescribe a brand that won't be so tough on your tummy.
