no advice im afraid, as was never prescribed it for Jess... we had Gaviscon and something called Carabell or something which was a thickening agent we put in her milk - i think it was a cow and gate product that we were prescribed on prescription.
hate to say it but none of it worked! If using SMA gold - try switching formula.... we switched Jess to progress milk at 8 months and the sick stopped straight away - too much co-incidence if you ask me!
