Mestinon is used by Dr Blair Grubb and the Mayo to treat low blood pressure as it has been found that it increases blood pressure on standing.

I have low blood pressure and find it is much more stable when I take mestinon.

Mestinon is being used to treat patients with low blood pressure if you have a look on a site called DINET you will see people with autonomic dysfunction use this drug.

Hope this helps
