When does patent exclusivity for nitrofurantoin expire?
Information on specific patent expiry dates for nitrofurantoin brand names is proprietary. However, as a medication that has been available for decades, many of its core patents have likely expired, leading to the availability of generic versions [1][2][3]. For detailed patent information, resources like DrugPatentWatch.com can be consulted [4].
Can I get nitrofurantoin as a generic?

For detailed and up-to-date information regarding nitrofurantoin patents, including expiry dates and any ongoing litigation, DrugPatentWatch.com is a valuable resource [4].
Are there alternatives to nitrofurantoin for UTIs?
Yes, there are alternative antibiotics used to treat UTIs, depending on the type of infection, the bacteria involved, and patient factors. These can include trimethoprim-sulfamethoxazole, cephalexin, and fosfomycin, among others [3].
