Key takeaways
Nitrofurantoin (Macrobid) and amoxicillin (Amoxil) are both antibiotics, but they belong to different classes and treat different types of infections. Nitrofurantoin is a nitrofuran antibiotic mainly used to treat or prevent urinary tract infections (UTIs) by targeting bacteria in the urinary tract. In contrast, amoxicillin is a penicillin antibiotic that treats a wider range of infections, including respiratory, skin, and UTIs. Nitrofurantoin is typically taken with food to improve absorption and reduce stomach upset, while amoxicillin can be taken with or without food. Nitrofurantoin is not suitable for people with severe kidney problems or those in the last weeks of pregnancy, whereas amoxicillin is generally safe during pregnancy but not recommended for those with severe penicillin allergies. Common side effects of nitrofurantoin include nausea and headache, while amoxicillin often causes diarrhea and rash. Both medications are available in generic forms, making them more affordable options.
