In the DIGest I received 31 August, David Ambuel writes <<My father, Philip, a retired pediatrician with PD has a problem I could use advise on. He has difficulty with frequent periods of low blood pressure. The episodes are frequent and severe enough that he feels washed-out and unable to move even though he is not rigid. Has anyone else encountered this problem? Are there any medications or herbal remedies that may raise blood pressure and not adversely affect the PD?>> I replied by e-mail, and was encouraged to send here my reply, which follows. Maybe I can help. I am a retired general practitioner, 51, with Parkinsons for 5 years. Your father's problem is actually quite common. The only side effect caused more frequently by anti-Parkinson meds is constipation. Almost all of the meds can lower the resting blood pressure, with the worst of the lot probably being the dopamine agonists, Parlodel and Permax. You don't say what your father is taking, but there are some considerations that are independent of meds. Probably the simplest thing to do is to increase salt intake. That of course implies that he could do that consistent with other medical needs. Often, support hose can help the "pooling" phenomenon in the lower extremities. Post-surgical knee-highs will often do the trick, but don't rule out just buying him a pair of women's panty hose with support. Leggs have two support models, one gentle, the other a little more squeeze. Licorice raises blood pressure, and has been used in this regard successfully by many folks. I am not aware whether there are herbal means to raise blood pressure, but there may be. General considerations are topped, of course, by safety concerns. Specifically, I refer to getting up from either a seated or recumbent position too fast. Most say that takinga few minutes to accomodate the blood pressure change. One little trick is to raise up to upright position from the bottom up, that is to straighten legs first, then allow upper body to gradually curl upwards to full upright. I should not fail to mention that all of this should be run past your father's physician. As docs, we are usually a little reluctant to have our own doc, to use him/her appropriately, and we tend to think that things like support groups for ourselves (and family members) are fiction.
