New names and new comedications

Tuesday 03 December 2019

We have renamed some of the comedications in the “Herbal/Supplements/Vitamins” class to make it clearer if possible interactions are due to the presence of multivitamins or to the comedication itself. Existing interactions have been revised to refer to when the comedication is given in a multivitamin preparation and new interactions have been added for when the comedication is given alone. The following comedications now have dual listings for “alone” or “in multivitamins”:

  • Ascorbic acid (Vitamin C)
  • Colecalciferol (Vitamin D3)
  • Cyanocobalamin (Vitamin B12)
  • Folic acid
  • Iodine
  • Nicotinamide (Niacinamide)
  • Phytomenadione (Vitamin K)
  • Pyridoxine (Vitamin B6)
  • Retinol (Vitamin A)
  • Riboflavin (Vitamin B2)
  • Thiamine (Vitamin B1)
  • Tocopherol (Vitamin E)

Six new comedications have also been added to the interaction checker:

  • Eletriptan (anti-migraine agents)
  • Ferrous fumarate (herbals/supplements/vitamins)
  • Filgrastim (other)
  • Moxonidine (hypertension/heart failure agents)
  • Trastuzumab (cancer therapies)
  • Trastuzumab emtansine (cancer therapies)

An update with all these changes is available for the iChart app and new versions of the "Overview of Interactions" PDF files (found in

Prescribing Resources) have been uploaded.
