Will I feel sedated if I take prazosin hydrochloride?

Will I feel sedated if I take prazosin hydrochloride?

Possibly: First, remember that everyone is unique and respond to medications slightly differently. Some people may feel sedated with prazosin, not everyone will. It also depends on what dose you are taking and how often. Prazosin trials suggest that about 8 in 100 people feel a sedating effect. Dizziness, headache and weakness are just as common.

What is the best med or supplement for and overactive sympathetic nervous system that doesn't sedate you? Thanks Docs!

???: There is such a condition as sympathetic hyperfunction syndrome, which has various manifestations; but the phrase "overactive sympathetic nervous system" is far too vague and imprecise to refer to any valid physiological concept. It sounds like something fanciful you'd hear in a health food store or from a reflexologist. You should repost describing in specific detail what you mean by it. ...Read more

How does Norepinephrin block pain in the Cns?Docs say i have an overactive sympathetic nervous system?Would nortriptyline create more symp cns problms

Neurotransmitters: This is a very complex question, and you need to discuss this in detail with your treating physicians. Both Norepinephrine and serotonin act on the dorsal horns of the spinal cord to inhibit excessive transmission of nerve cell fibers, thereby decreasing the central (brain) perception of pain. Nortriptyline should not worsen that, and may help some. The SNRI's medications help with pain relief. ...Read more

I think i've overstimulated my sympathetic nervous system by repeated stage fright, and now my body overreacts to everything. How can I reverse this?

Meditation, relaxation therapies, yoga, & biofeedback are some means to this end. Students learn to use mind to control body. Read relaxation response by dr. Benson & see heartmath.Com. ...Read more
