If I understand their formatting correctly, the bolded text on the website separates the different categories of vegan vs non-vegan medicine. The sentence about Triaminic being vegan comes after the bit about ones that are questionable. It's a little confusing but I don't think they are questioning that Triaminic is vegan.
These Medicines are Questionable:
Vicks Brand Day Quil
Comtrex Brand Cold & Cough Caplet, All four Liquid Products, Seven Caplet Products
Triaminic 's Cough & Sour Throat, Flu Cough & Fever, Cough Syrup and other 6 syrups for children are made without animal derived ingredients and there is no alcohol in them
