Nitrofurantoin, sold under the brand name Macrobid among others, is an antibiotic used to prevent and treat bladder infections, but is not as effective for kidney infections.[3][4] It is taken by mouth.[3]
Common side effects include nausea, loss of appetite, diarrhea, and headaches.[3] Rarely numbness, lung problems, or liver problems may occur.[3] It should not be used in people with kidney problems.[3] While it appears to be generally safe during pregnancy it should not be used near delivery.[3][5] While it usually works by slowing bacterial growth, it may result in bacterial death at the high concentrations found in urine.[3]
Nitrofurantoin was first sold in 1953.[6] It is on the World Health Organization's List of Essential Medicines.[7] It is available as a generic medication.[3] The wholesale cost in the developing world is between US$0.10 and US$9.20 for a course of treatment.[8] In the United States, the wholesale cost is about US$8 for a course of treatment as of 2018.[9] In Canada this is about 21 CAD as of 2023.[10] In 2017, it was the 185th most commonly prescribed medication in the United States, with more than three million prescriptions.[11][12]
