One of the antibiotics for anaerobic bacterial infection is metronidazole, which is the generic name of Flagyl. It is a prescription drug prescribed for individuals suffering from abscesses in the abdomen, liver, pelvis, or brain formed by anaerobic bacteria. The drug is also used to treat other types of infection such as Giardia infections and bacterial vaginosis.
Some of the side effects of metronidazole include headaches, loss of appetite, nausea, and a metallic taste. Metronidazole interacts with other drugs including warfarin, cimetidine, cholestyramine, and amprenavir. Metronidazole should not be taken by pregnant or nursing mothers because of the risk of passing the drug to the baby. The drug isn't prescribed for those that have allergies to nitroimidazole derivatives.
