i have a JG tube, not a PEG, but I inject pepcid into it daily (2.5ML) and also Docusate Sodium (10ML), and this seems to keep everything regular. I'm not sure that'll work as a long term solution though. That's for a doctor to answer.
Diagnosed 6/05. Stage III SCC of the oral tongue. Nodes showed negative upon biopsy. 7/25/05 started Chemo of Cisplatin & Erbitux & 30 IMRT Sessions + daily Ethyol. 12/9/05, 75% hemi-glossectomy. Recovering since.
