multivitamins odevixibat

Applies to: Vitamin B Complex 100 (multivitamin) and odevixibat
Monitor

Odevixibat may affect absorption of fat-soluble vitamins (FSV) including vitamin A, D, E, and K. In clinical studies, new onset or worsening of existing FSV deficiency was reported in 5% of placebo-treated patients, and in 16% of odevixibat-treated 120 mcg/kg/day patients. However, none of the odevixibat-treated 40 mcg/kg/day patients had new onset or worsening of existing FSV deficiency.

Management

Clinical and laboratory monitoring of FSV levels is recommended prior to and during treatment with odevixibat. Monitor INR (for vitamin K) and serum vitamins A, D, and E, and supplement if a deficiency is observed. Odevixibat should be discontinued if FSV deficiency persists or worsens, or if bleeding occurs despite adequate FSV supplementation.
