If a decision is made not to include certain WMF monographs in the NF, then all associated information from the appendices should also be removed. In the interaction appendix, a careful search should be made (using the Find command under the Edit menu of the word processor) for the name of the active ingredient and this should be followed by careful deletion of all interactions and reversals for the deleted medicine. As most of the interactions and reversals in the WMF are presented with individual medicine names (except for antacids, oral contraceptives and vaccines) this could be a straightforward task, but care must be taken to avoid the accidental deletion of any other information.
