The generic name for Macrobid is nitrofurantoin monohydrate/macrocrystals [1].
What is nitrofurantoin monohydrate/macrocrystals used for?
Nitrofurantoin monohydrate/macrocrystals is an antibiotic primarily used to treat and prevent urinary tract infections (UTIs) [1]. It is effective against a wide range of bacteria commonly responsible for these infections.
How does nitrofurantoin monohydrate/macrocrystals work?
Nitrofurantoin is a bacteriostatic antibiotic, meaning it inhibits the growth of bacteria. It is reduced by bacterial enzymes to intermediate products that denature bacterial proteins, including enzymes involved in essential cellular functions such as respiration, metabolism, and cell wall synthesis [2]. This disruption ultimately leads to bacterial cell death.
When does patent exclusivity for nitrofurantoin monohydrate/macrocrystals expire?
Information on patent expiry dates for specific formulations of nitrofurantoin monohydrate/macrocrystals can be found on sites like DrugPatentWatch.com [3]. These dates indicate when generic versions of the drug may become available.
Are there other generic versions of nitrofurantoin?
Yes, besides nitrofurantoin monohydrate/macrocrystals, other formulations of nitrofurantoin exist, such as nitrofurantoin capsules. Generic availability and specific product names can vary [4].
What are the potential side effects of nitrofurantoin monohydrate/macrocrystals?
Common side effects can include nausea, vomiting, diarrhea, headache, and loss of appetite. More serious side effects, though rare, can include lung problems (such as shortness of breath, cough, fever), liver problems (jaundice), and nerve damage [1].
Can I take nitrofurantoin if I have kidney problems?
Patients with impaired kidney function should use nitrofurantoin with caution or avoid it, as reduced kidney function can affect the drug's excretion and increase the risk of side effects [1].
