bacterial infection
"Took for c. diff. infection; on 500mg/3x daily for 10 days. Close to 30 weeks pregnant. Horrible side effects from taking the medicine, such as: extreme fatigue, dizziness (obviously steered clear of driving), heart palpitations, and an increase in mood swings/depression. Heard many others had issues on Flygyl as well. Did clear up c. diff. infection though."
