hives/yeast die off?

Two days ago I started a new product call Qviana. It is a probiotic. Today I broke out in hives and wonder if it is a reaction to the die off of yeast. Should I keep taking the probiotic and work the dead yeast through my system? If continuing the product will clear the yeast I will try to suffer through the hives. Anyone who may have had similar reaction any info would be helpful. Tweet
