Antibiotics can be life-saving — but they’re not precise. While they wipe out the bacteria making you sick, they also clear out many of the good bacteria your body relies on. That’s why so many people deal with digestive upset during and after a course, and why rebalancing afterward matters.
What antibiotics do to your microbiome
Antibiotics can’t tell friend from foe. A single course can significantly reduce the diversity of your gut microbiome, and it can take weeks — sometimes longer — for those populations to recover on their own. For women, antibiotics can also disrupt the vaginal microbiome, which is why yeast infections and BV sometimes follow a course.
Common after-effects
- Diarrhea, bloating, or general digestive upset
- Sluggish digestion as good bacteria recover
- For women, intimate imbalance, odor, or irritation
How to help your body rebalance
- Replenish good bacteria with a probiotic. Taking a probiotic during and after antibiotics helps reintroduce beneficial strains. (Space it a couple of hours apart from your antibiotic dose.)
- Feed them with prebiotic fiber — onions, garlic, oats, bananas.
- Eat fermented foods like yogurt and kefir.
- Be patient and consistent — rebuilding takes a few weeks.
A daily probiotic with named strains and prebiotics — like the Quixao Daily Gut Probiotic or, for intimate balance, the Vaginal Probiotic — is built to support exactly this kind of rebalancing. Probiotics support your natural balance and are not a treatment for any condition.
