The wall chart was based on the Australian Pharmaceutical Formulary. This contains the requirements of the Pharmaceutical Society of Australia on the labelling and counselling which should be given when drugs are dispensed. Clearly, doctors have additional factors to consider when they are prescribing. The 'Other comments' column was intended to include a few of those considerations, but it was not intended to be a complete list of prescribing instructions. The column contains enough space for additional information to be included, so practitioners can add Professor Gyory's warning and any other advice they choose.
I have also been advised that the labelling for doxycycline differs slightly from the other tetracyclines. Doxycycline can cause oesophageal or gastric irritation, so it should be taken with fluids or food. The advice on the wall chart for doxycycline should be '4 (delete milk) B,D'.
