We have been additive-free for over a year. We were able to drop my daughter's epilepsy medication and she enjoyed more than a year trouble-free until experiencing a seizure after eating Strepsils throat tablets during a cold. A call to the pharmacy revealed that all Strepsils tablets contain artificial colours and this particular product, Honey and Lemon, contains Quinoline yellow artificial colour 104, not permitted in Australia (at that time), and not listed on the label. – by email

(After this episode I complained to the TGA that Strepsils with an unlisted artificial colour not permitted in Australian food could be purchased from supermarket shelves next to foods that require artificial colours to be listed on the ingredient label. The TGA official who took my complaint laughed. Soon afterwards, quinoline yellow 104 was approved for use in Australian foods – and colours either artificial or natural still don't have to be listed on the labels of pharmaceuticals according to TGA regulations. – Sue)
