Metronidazole
"Negative experience.

If you are having anorexia, and nausea ... especially if you have vomiting and diarrhea...and start feeling weak, go back to the doctor.

On Day 5  I went to the E.R. and then admitted (for 9 hours) for lo Sodium - was dehydrated.

attending felt it was a combo of F w/the diuretic I take ... altho it's quite a low dose, and I stopped on day 3.

They gave me IVs of saline, Mg, K (all were low) with saline labs every 2 hours.

Don't fool around with this. Get seen.  I'm not sure what would have happened had I waited."
