Amoxicillin / clarithromycin / lansoprazole
"On Day 6 of the 14 day treatment. The side effects I've experienced haven't been too bad: the bad taste in your mouth (usually at night and first thing in the morning), hard time staying asleep (insomnia), yellow stools, and some left side aches which I think may have to do with constipation. I'm sure I would be worse if I didn't take a probiotic with every dose of these meds."
