vaginapagina | Contagious antibiotics causing yeast infections? (Reply)

My boyfriend and I always get sick at the same time for obvious reasons. He usually goes to the doctor and gets medicine, I don't. He is often diagnosed with a sinus infection and put on antibiotics. Now I have yet another yeast infection... and it dawned upon me that the two events coincide, and have probably done so in the past. Can his being on antibiotics transfer to me somehow? Or maybe,does a weakened immune system make one more susceptible? I take acidopholus and garlic supplements, wash (with plain water) when I am sweaty or sticky, and even use a preventative vinegar douche the week before my period. I honestly don't know why I keep getting these infections.
