If, as did my OH, suffer a generic drug that had a lesser beneficial effect than the original, (and when we mentioned this it was noted that they had to have Requip rather than Ropinirole), then you may agree with me. Same basic ingredient but maybe not in its entirely identical in composition.
Our consultant, our PSN, and lately nurses at the memory clinical ALL agree that generic drugs MAY not be as effective in controlling symptoms as the original. I even suffer this with one of MY problems; one brand works well another does nothing.
Why do you think that generic drugs are cheaper??? There has to be a reason, other than they are out of licence and so can be manufactured far cheaper because it does not involve the research that went into the original with all the cost of testing and trials. Once out of license they can be manufactured by any firm, both here and abroad to copy, mostly abroad it seems and who knows what they contain!
Having the same problem now with a medication prescribed by the memory clinic and for the last few months have received THREE different brands. IF this medication is not found to be effective then it will be stopped. How can we evaluate its effectiveness if we have a different brand each time??!!!
