The only antibiotic I've ever taken that killed off good gut bacteria is one called Ceftin. It didn't cause constiation, but had the opposite effect. A pharmacist friend suggested at the time to eat PLAIN yogurt and not the stuff with the fruit in it. I suppose one could add fresh fruit, but not the kind with added sugar. Added sugar defeats the effectiveness of the yogurt. I suppose one could take probiotics too, Plain yogurt is all you need.
