Correct answer: BNitrofurantoin can darken urine and should be taken with food or milk

Nitrofurantoin can darken urine and is best taken with food or milk to improve tolerability and absorption. The patient should complete the prescribed course and seek help if symptoms worsen, fever develops or there is flank pain. Routine additional contraception is not required for most antibiotics unless vomiting, diarrhoea or enzyme induction applies.
