Metronidazole
"I have taken this medication many times due to recurring bacterial vaginitis. It causes me to have severe heart palpitations, panic attacks, nausea and severe dizziness and causes me to feel like I'm just shaking inside. The medication itself works very well. It does get rid of the infection. I take Diflucan along with it to prevent a yeast infection but I recently found out that the medication has caused my liver enzymes to rise."
