Hi k8
My daughter has suffered with reflux since birth. We started on ranitidine 3mg/kg three times a day, then went on to 4mg/kg twice a day at age six months.
At twelve months we switched to omperazole, and have been on it for the last two years.
The ranitidine dose is safe, and as sqad rightly said, as long as your daughter is being monitored by the paediatrician / gastroenterolgist try not to worry (should also add I am a pharmacist and the dose is spot on).
The omeprazole works much better than ranitidine ever did, although does not get rid of all her symptoms.
As a thought, if you are weaning, how about trying the omeprazole (Losec MUPS) again mixed in with some yoghurt?
All the best, Liz.
