Behandling med koagulationshæmmende midler Antikoagulansbehandling skal overvåges nøje hos patienter, der får warfarin eller tilsvarende præparater, idet det er vist, at galdesyrebindende præparater reducerer optagelsen af vitamin K og derfor påvirker warfarins koagulationshæmmende virkning.
Anticoagulant therapy Anticoagulant therapy should be monitored closely in patients receiving warfarin or similar agents, since bile acid sequestrants have been shown to reduce absorption of vitamin K and therefore interfere with warfarin's anticoagulant effect.
