Flagyl Asthenia Reviews

Thu, 07 Jan 2010
The exact same thing happened to me after I was prescribed high dose Flagyl for 5 days for suspected diverticulitis (painful bloating, frothy yellow diarrhea, excessive foul gas, etc.) my doc also put me on a Clear Liquid Diet for 3 days before I had this episode... I called 911 from work because I felt chest tightness, shortness of breath, extremely lightheaded, and couldn't stand up or walk without almost passing out. I was confused also with difficulty concentrating and speaking. EMTs found my blood pressure to be 170/100 and my EKG showed a "Right Bundle Branch Block". I felt better after they gave me nitroglycerin and 4 baby aspirins. At the ER my EKGs and cardiac enzymes were normal. A CT scan of my abdomen failed to show any diverticulitis- they told me it looked completely normal. They also said I was dehydrated with a slightly low potassium level which was to be expected after 9 days of diarrhea. They thought my episode was caused by severe intestinal spasms probably due to side effects of the Flagyl and ibuprofen I had taken that morning on basically an empty stomach!

I am currenty on Flagyl for a pelvic infection in combination with vibramyacin. This morning I took the vibramyacin and then was planning on taking the Flagyl an hour later, but I spent the this morning vomiting. I called the dr. and was told by my dr. to continue taking both but with food..vibramyacin said to take on empty stomach, but I think the Flagyl was effecting me from the night before and not drinking enough water in combo with the vibramyacin .. and I think that's why I threw up I did not take the Flagyl before I threw up, however, after I was ok and spoke to the dr hours later , he told me to continue taking both but I took the Flagyl thinking it was the vibramyacin causing all the trouble, I had stomach burning all day and then just a half hour ago I took the Flagyl again and immedialtey had I realized soon after taking it again that it is the culprit causing a heartburn like burning senstation in my stomach and lower esophogas... I am calling my dr. tomorrow again to tell him that I can't deal with this. I tried to push through since I want to be fully rid of the pelvic infection but this is ridiculous. It feels like a horrible heartburn burning sensation.
Fri, 09 Jul 2010
