Clarithromycin
"I would like to know what this drug is made from. The horrible metallic taste is making me gag. I have tried everything you can think of to get rid of it. It's waking me up at night from the taste. I don't know if the H.pylori symptoms or this is worse. I have 5 days to go on this and am dreading every tablet I have to swallow. I feel it's poison."
