Key takeaways
Metronidazole (Flagyl) and Minocycline (Minocin) are both antibiotics, but they belong to different classes and treat different types of infections. Metronidazole is a nitroimidazole antibiotic that treats bacterial and parasitic infections like bacterial vaginosis and trichomoniasis. It is taken orally, usually three times a day, and should not be mixed with alcohol due to serious interactions. Common side effects include diarrhea, nausea, and a metallic taste. Minocycline, on the other hand, is a tetracycline antibiotic used for bacterial infections such as UTIs, respiratory infections, and acne. It can be taken with or without food, but it makes you more sensitive to the sun and can stain children's teeth. Both medications are available as a lower-cost generic. Minocycline is not recommended during pregnancy and can interact with birth control pills and blood thinners. Both medications have serious side effects, but they differ in their specific risks and the types of infections they treat.
