There are many different prenatal vitamins currently on the market, and a pharmacy cannot possibly stock every single brand. If your pharmacy does not carry Prenate DHA prenatal vitamins, you have a few different options. You can take your prescription (or have it transferred) to a different pharmacy that carries Prenate DHA; you can have your healthcare provider give you a prescription for a different prenatal vitamin; or you can ask your pharmacy to stock Prenate DHA for you.
