Is diarrhea a normal side effect of antibiotics and is there any way to treat it?
Unfortunately, diarrhea is a common side effect of antibiotics. Diarrhea is a defense mechanism of the body, as it is trying to rid itself of the bad bacteria. With diarrhea comes the possibility of dehydration, which is why it is important to drink plenty of fluids while on any antibiotic. Diarrhea, while it is getting rid of the bad bacteria, may also get rid of the good bacteria (the kind that naturally exists in our stomachs that help regulate our digestion). You can help replace good bacteria with an over-the-counter probiotic.
