Does low coumadin make one nauseous?

Unless you're doing home testing, I'm assuming that the only time you know that the Coumadin level is lower than the therapeutic range is at the facility which does the testing? Would these be the times when nausea occurs?

Lower than therapeutic levels of Coumadin would increase the risk of a stroke. I'm not sure about nausea but I suspect something else is going on.

What other factors can be associated with the nausea? How often does the nausea occur and have you raised the issue with an internist or PCP?
