Consider Zaxine After Usual Options for IBS With Diarrhea
The approval of Zaxine (ZAK-seen) for irritable bowel syndrome with diarrhea (IBS-D) in adults will lead to questions about IBS-D management.
Zaxine (rifaximin) is an oral antibiotic that has minimal systemic absorption...and may help by restoring the balance of bacteria in the gut.
But efficacy for IBS-D seems modest. Zaxine improves symptoms in about one in 10 patients...and over half of patients who respond will need another Zaxine course within 6 months.
