Dear SJS--I hope you have just downloaded the new"PD topics by email" message from John Cottingham. In it you will find the archive info for 2 documents which may be helpful--the Algorithm for Managing PD--#219 and the Constipation Protocol (and correction) #108 &109. If you missed the post today, ask John Cottingham for it.It also tells how to use the archives. <[log in to unmask]> Your mother has certainly had a very rough time, and she must be a strong and determined lady! A question--does your doctor mention the term "megacolon" as a possible condition she could have? My husband uses Propulsid and Lactulose on a daily basis--2 Propulsid tablets 15 min. prior to each meal(also called cisapride). Lactulose(the generic,with trade names Duphalac and Chronulac)is a sugar syrup which the pharmacist says in quantity has a laxative effect, and may be taken any time, not necessarily before meals. Peter uses 1 Tblspoon 2 or 3 X day. On occasion after several days of "no results" he has used Senokot tablets on doc's advice,& enemas. The constipation seems to be cyclical, and may not be a problem for several wee ks, then flare up again, but has never been an impaction--though that is a real concern, partly due to the constipating effects of the meds, partly due to the slow gastric emptying which goes along with PD. You know, of course, that no 2 people have PD quite the same, and changes must be checked with your doctor--hope it's a better neuro now! The Algorithm, from a special edition of_Neurology_ journal, is intended for doc, but is very complete and you may find it helpful. Sorry to hear you and your mother have had such a hard time--hope things go better now. If you're not on CARE list for PD caregivers,you might join us there: Send message: [log in to unmask] SUBscribe CARE (your first and last names) I'd be glad to add you to that list.
