Do you know, I think I was so desperate to get on with using the new patches that it is only now whilst sitting in bed, that I have looked at the packaging and the box is looking a bit sad (falling apart and old looking - ha! I know the feeling!!) and there is no patient information leaflet and actually no dosage detail on the box!! I have looked at the individual packets and these do show content details but the writing is so small I can't read it!!! Will have to find the kids' magnifying glass tomorrow!!
