The longer half-lived iodine-125 is also occasionally used when a longer half-life radioiodine is needed for diagnosis, and in brachytherapy treatment (isotope confined in small seed-like metal capsules), where the low-energy gamma radiation without a beta component, makes iodine-125 useful.
Split and merge into it. Answered by The Community. Making the world better, one answer at a time. Macrodantin is all macrocrystalline nitrofurantoin while Macrobid is a combination of the macrocrystalline nitrofurantoin as well as the nitrofurantoin monohydrate form (25% and 75% respectively).
Other Forms of Generic Nitrofurantoin Care must be taken to avoid confusing generic Macrobid with generic Macrodantin Â® (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.
