Drug Interactions

Calcium Polystyrene Sulfonate: Sorbitol may enhance the adverse/toxic effect of Calcium Polystyrene Sulfonate. More specifically, concomitant use of these agents may increase the risk for intestinal necrosis. Avoid combination

LamiVUDine: Sorbitol may decrease the serum concentration of LamiVUDine. Management: When possible, avoid chronic coadministration of sorbitol-containing solutions with lamivudine, but if this combination cannot be avoided, monitor patients more closely for possible therapeutic failure associated with decreased lamivudine exposure. Consider therapy modification

Sodium Polystyrene Sulfonate: Sorbitol may enhance the adverse/toxic effect of Sodium Polystyrene Sulfonate. More specifically, concomitant use of these agents may increase the risk for intestinal necrosis. Avoid combination
