Metronidazole
"This drug has not been a good experience for me (I'm on Day 10 of 14) and I really hope it destroys the H. pylori. I've had gastritis off and on for years until an attack so painful I had to go to the ER. The taste is almost unbearable. It makes me want to eat just to temporarily get rid of the awful taste. Good to know I am not the only one who is creating a lot of foul saliva, too. In the first 2 days, I was very dizzy and, since this was one of those side effects we are 'supposed to contact' our doctors about, I called. Two days later she insisted the dizziness and nausea were due to a virus. Today I ordered some Neem & Aloe Vera Inner Gel because there is pretty good information on these two botanicals' impact on H. pylori. Never again."
