sinusitis
"I have been prescribed Biaxin twice in the past three months. The first onset of sinusitis took 6 weeks to clear. 1 week before Christmas it comes back with the worst pressure, 2 ER visits later they tell me the sinusitis is back. This round with Biaxin has left me: dehydrated, constant bathroom trips after eating anything, weight loss (12lbs in 2 weeks). "
