I understand how stressful it can be when you cannot find your prescribed medication. Both Niftran SR and Uribid contain the exact same active generic medicine, nitrofurantoin, meaning they are therapeutic equivalents. However, because you are so close to your delivery date, it is incredibly important to consult your obstetrician before switching. Near term, your doctor will want to closely supervise your treatment or may prefer to select a different antibiotic entirely to ensure the utmost safety for you and your baby. Please contact your doctor's office today to confirm if they approve of you switching to Uribid.

Can I use Uribid as a substitute for Niftran SR 100mg while I am 36 weeks pregnant, since I cannot find Niftran SR at the pharmacy?
