bacterial infection
"TRUST ME:  While you're waiting for your script to be filled, walk on over to the vitamin aisle & grab a bottle of good old Acidophilus. Whichever brand has the highest 'count' (1 Billion, 1 Million, etc.). It may pricey but believe me, it's worth it. This will counteract & help gastrointestinal upset & possible yeast infection. Antibiotics rid the body of bad bacteria but also the good which is why we have side effects. Take it with any antibiotic!
Plus, it won't go wasted!  This is a beneficial probiotic for afflictions you may not think of i.e. gas, IBS, skin issues & you can't take too much. Take it daily- even after finishing any antibiotic."
