Flagyl saved my life. I had Giardia. After 3 courses of medication, Flagyl combined with Albendazole finally cleared it. I thank God for this medication. Yes, it was awful to take, should not be taken lightly and always under a doctor's supervision, alcohol definitely needs to be avoided while taking, and it does have nasty side effects. For me, the side effects passed and I was able to finally recover from the horrible nightmare of Giardia.

Urticaria and internal parasites:
After a trip into Mexico I developed a severe outbreak of measle like red spots on my body. A fecal examination revealed I was infested with 3 different amoebas: Coli, Hystolytica, and Blastocystis Hominis.
See descriptions here:

Three separate treatments with Flagyl cured the infestation. I do not know if it was one or a combination of the parasites which caused the outbreak but the red spots disappeared after treatment and have never returned.
