Other Forms of Generic Nitrofurantoin

Care must be taken to avoid confusing generic Macrobid with generic Macrodantin® (nitrofurantoin macrocrystalline), a similar medication that is taken four times a day. The generic names are quite similar and are often abbreviated in order to fit on prescription labels. While most pharmacists are aware of this potential problem and are careful to avoid confusing the two, it is a good idea to check with your pharmacist if your generic Macrobid looks different from the Macrobid pills you have received before.
