I'm on a dose of two antibiotics following a post op infection. After the actual op I was given antibiotics and developed thrush. The woman at the pharmacy said that next time I should make sure I eat bio yogurt (I think?) to avoid it again. But I cant quite remember what sort of yogurt she means. Theres so many there. Also, she said that the anitbiotics kill all bacteria good and bad. So...what is the point of the bio yogurt? Wont it kill those bacteria too? Sorry to sound so dim. Any advice please.
