To List friends A member of our support group has a problem and hopes the list can help. This is her story. Some (many?) drugs have a filler added to the active ingredients in the tablet .The Mirapex sold in Canada has just such a filler--- cornstarch. Cornstarch is not supposed to cause trouble but there are people who are allergic to it. This is what happened... She filled her prescription for Parkinson medication, she took the first dose and she had an allergic reaction. She read the fine print that comes with the Mirapex tablets and there, in the list of ingredients, she saw the problem-- cornstarch. She is severely allergic to cornstarch ............. But this is the puzzle. She has been in a clinical trial for a year or more-- a clinical trial of Mirapex! She had no allergic reactions to the tablets used in the trials, in fact everything was just great. Is it possible for the meds used in the trial to have a different filler from the meds finally brought to market? Her doctor says she should stop taking Mirapex but it is not good to stop suddenly!!!! There are lots of questions raised by this story--- Who makes Mirapex? Have they a web page? An 800 number? Do all versions of Mirapex contain cornstarch.? Do some tablets use other fillers? What are they? Who knows for sure what was used in the test tablets? Anyone else allergic to cornstarch? Does anyone have any suggestions as to what we can do? Thanks Anne Rutherford 64 dx1980
