Macrobid is a medication used to treat uncomplicated urinary tract infections caused by specific bacteria. It works by attacking the bacteria in the urine, preventing them from growing and multiplying. You will take it as a 100 mg capsule, usually one capsule every 12 hours for seven days, and it's best to take it with food. One important warning is that it can cause serious lung problems, so if you experience any breathing issues, you should stop taking it immediately. Additionally, it should not be used by people with significant kidney problems, as this can increase the risk of side effects.
