Nitrofurantoin is often used to treat urinary tract infections, and it is an antibiotic. Similar to most prescription drugs, it does have some side effects, with the most minor kinds being vomiting and diarrhea. Some patients feel generally ill when taking this drug, as flu symptoms and even sudden weight loss may occur during the treatment period. Patients may find that they have a hard time breathing normally when taking this drug, and might also experience chest pain and problems with the skin, including a red, itchy rash. Such serious symptoms should typically be reported to a doctor right away.

For example, stomach upset and resultant vomiting are some of the most commonly experienced side effects, and this is often paired with diarrhea.

Fortunately, none of these side effects are considered serious, though patients are advised to contact their doctor soon if the diarrhea turns bloody or is particularly watery.

A hacking cough and a feeling of weakness can also be considered serious, as can tingling and numbness of the extremities.
