I know that 80mg is safe as that is what I prescribed, and that was as high as we went with it for me, and that was prescribed by a GP/LC, perhaps we can try and find you a GP who knows more about it, or some information you can take in?

Domperidone This article looks like it has the information you are looking for, unfortunately it is not from and Australian source, but the dosages it lists is 3 x 10mg x 3 daily (90mg) or 2 x 10mg x 4 daily (80mg)
