PreNexa is used for treating or preventing a lack of vitamins or minerals before, during, and after pregnancy and while breast-feeding. It may also be used for other conditions as determined by your doctor.
PreNexa is a vitamin, mineral, iron, folic acid, docosahexaenoic acid (DHA), and stool softener combination. It works by providing vitamins and minerals to the body to help meet nutritional requirements. The stool softener helps prevent constipation that may occur with iron products.
