Do not take Cipro with calcium, milk, yogurt, probiotics or with Nexium (which contains magnesium). Cipro is a quinalone, and is
effective against mycobacteria, which don't have cell walls, but is not effective against other many strains of bacteria. The taking of an anti-viral is a mixed blessing. Go to the FDA site for information on Valtrex. A culture should have been taken, but this isn't done very often these days.
