Key takeaways
Metronidazole (Flagyl) and Malarone (atovaquone/proguanil) are both prescription medications, but they treat different types of infections. Metronidazole is an antibiotic used to treat various bacterial and parasitic infections, such as bacterial vaginosis and trichomoniasis. It is taken multiple times a day and has a generic form available, making it a lower-cost option. On the other hand, Malarone is an antimalarial medication used to prevent and treat malaria. It is taken once a day and is not available in a generic form. Metronidazole has a serious interaction with alcohol and can cause a metallic taste in your mouth, while Malarone is generally well-tolerated but can cause vivid dreams and liver problems. Additionally, Malarone is not recommended for people with severe kidney or liver problems, or for pregnant or breastfeeding women.
