An Introduction to Nitrofurantoin Side EffectsAs with any medicine, side effects are possible with nitrofurantoin (Furadantin®, Macrobid®, Macrodantin®). However, not everyone who takes the drug will experience problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
