Nitrofurantoin is a molecule available in the form of capsules (notably Furadantine®) or pills (Furadoïne®), which is administered in cases of lower urinary tract
infections in women or cystitis
. Treatment courses usually last for 5 to 8 days. This treatment method is sometimes used instead of what is known as the "one minute" treatment method, where one administration of one molecule is required, in certain specific cases. It is also used in preventative therapy for recurring urinary infections. It is worth noting that urine can take on a brown coloring during this treatment.
