oh, interesting..I am almost sure they do because another member here is using the 2g. Maybe I'm thinking of Salofalk...
If you really want to know for future reference, you should call the pharmacy anyway just to check. The Pentasa comes in a 2g...so, that would be another option if it's available in the US.
Using half..I've never done so, but one forum member, gaff, does...hopefully she'll come on and share the experience.
Canasa is easy to use..but they can leak if one has gas..but many use the suppositories and have no problems. Personal preference..but if that's all that was available, I'd use them for sure.
One must experiment and use the meds available as effectively as possible. Nothing is really written in stone and there is flexibility. Some members come up with different ways of tapering that I've not thought of...could definitely work for someone, and if it works, it's a method worth trying....especially if nothing so far has worked.
I would suggest your son use the Canasa for when he starts tapering the Rowasa and use it for the nights not using the Rowasa..I can explain later.
Keep us posted.
