Bacterial Infection
"Prescribed 300 mg 3x a day for five days. Take during a normal sized meal. Side effects have been occasional diarrhea and now the worst chest pain/heartburn. Took the medicine before bed, didn&#039;t lie down until later but woke up with incredible pain in my chest that spread. Before reading these posts, the chest pain was so bad I was ready to go to the ER. Unsure how long this heartburn will last, otherwise this antibiotic did it&#039;s job and the infection is is mostly gone. Very effective. Still have a couple more days to go. "
