No. In order for the effect to work, you need the item to bring you to a specific page.
Say you want to increase a character's health by using a item. You can put this on the item script page.
$DEST := @P10
%HEALTH := %HEALTH + 10
What this say is that when you use the item, it will bring you to page 10 and increase your health by 10. Of course the page number and the health can be easily change by switching the number with whatever number you want to switch it with.
