Hello. I'm sorry your mother is having problems with her blood pressure and her diabetes
. The medication she was given -- Galvus/metformin
-- is a combination of drugs that is designed to lower blood glucose
levels in diabetics. It's quite effective for this purpose, but (like most medications) it does have side effects. The metformin in this combination is well known for causing gastrointestinal problems, such as nausea, vomiting
If your mother is not able to tolerate her medication, she should call her doctor. It's very important that she gets her blood glucose under control as soon as possible.
