Bioton IV Multivitamin Ascorbic Acid
ModerateThe leaflet only says that bleomycin can be inactivated by ascorbic acid and riboflavin, and it says nothing about what happens when multivitamin and ascorbic acid are taken together. So no interaction between these two medicines is stated.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
