I have to tell you that my efforts to find "something" that even eased the nausea caused by bupre proved useless despite many many suggestions and medications that people on this sight had used and believed worked for them. For me none of the GP prescribed antinausea medications worked nor did the OTC medicines or those such as cannabis, ginger, and many others kindly put forward by members of this forum
Most GPs are ignorant on the topic of RLS and tend to put their "heads in the sand". I was lucky with a younger GP who was prepared to work with me. We both agreed that bupre was causing my nausea and you have to be sure that is the case with your Mum? If it is then my (and my GP) research and that of a fellow contributor to this site, Twicher707 in USA, should be tried.
Nausea is caused by bupre when the level in the blood exceeds a certain concentration and so it is important that the bupre concentration is steady and below the concentration (will probably vary according to the person) that causes nausea. Lets call it the "nausea % " The use of only tablets is most likely to cause the nausea % to be exceeded if the smallest ( I think that is 200mcg) tablet is taken whole. It seems that when a 200mcg tablet is taken that after about an hour the amount of bupre released is high enough to exceed the nausea %.
Therefore it is important to have a steady "background" concentration of bupre that a patch can provide. Of course that size of the patch must also be below (but as near as possible) to the nausea % line. I believe the smallest in UK (I use it) is 10mcg/hr or 0.24mg per day.. If this is not on its own enough to block RLS (try it) then small portions of tablet (start at 50mcg late in the evening) will be needed. Remember that the "weekly" patch only last 5 or 6 days and that a freshly applied patch needs at least 12-18 hours to reach it stated dose and so the patches need to be overlapped in application
I hope this helps but would appreciate you posting the outcome please.
