As of April 1, 2013, an inactive ingredient was removed from the medication Asacol and therefore this medication is no longer being manufactured. Asacol will no longer be available in pharmacies once they run out of their supply. While “Asacol” is no longer being manufactured; “Delzicol” which is a new medication with the same indications for use as Asacol is now available. Delzicol is produced by the same pharmaceutical company as Asacol (Warner Chilcott) and it is bi-equivalent to Asacol. There was one inactive ingredient which was removed from Asacol known as “dibutyl phthalate” or DBP and another inactive ingredient was added in its place. Because of the removal of this inactive ingredient and addition of another inactive ingredient, the name of the medication had to be changed. There was no safety indication for the removal of this inactive ingredient. The medication Delzciol has the same indications for use as Asacol and is dosed the same. The only difference in dosing instructions from a Food and Drug Administration perspective is that Delizcol should be dosed one hour before a meal or two hours after a meal.
