Is probiotics a goodthing to takeafter taking doxycycline? I developed gastritis n GERD. Heard probiotics repopulates bacteria. Any bad probiotic effects

Probiotics. Most people don't need probiotics after taking a course of antibiotics, since the normal bacterial flora of the gut repopulates rapidly after stopping antibiotics. If you have a history of C. difficile, it may be useful to take probiotics, however. Otherwise, studies do not support their routine use. Having said that, there are not usually many side effects, if you do decide to try them. Good luck.
