methenamine lactobacillus acidophilus
Applies to: methenamine / sodium acid phosphate, Probiotic Formula (bifidobacterium infantis / lactobacillus acidophilus)
ADJUST DOSING INTERVAL: Coadministration of oral probiotic preparations with oral antibiotics may reduce the efficacy of the probiotic. It has been theorized that concomitant antibiotics may kill the live organisms found in lactobacillus-, bacillus coagulans-, and bifidobacteria-containing oral probiotic preparations. However, the clinical significance of the interaction has not been established.
MANAGEMENT: Although data are limited, it may be prudent to advise patients to take oral probiotics at least 1 to 2 hours before or after an oral antibiotic.
