@erinrackham: Week 1–Guanfacine for hyperadrenergic POTS (.25 mg IR). I still feel more sedated than normal (napping every day right now), but I’m also staying out of fight/flight, which feels great. My executive functioning is improved, heart rate is more stable & lower, and cold intolerance is still better. It feels like Guanfacine is “good, not great”, so far, but I want to give my body time to adjust and see how I feel in a few weeks! #Guanfacine #HyperadrenergicPOTS #HyperPOTS #longCOVID

Day 3 of 1mg ER guanfacine gave me terribly low blood pressure and low sleeping heart rate, had to stop.

I reacted bad to guanfacine, I like clonidine much more.

I’ve read that it takes a few weeks to regulate, I’m 4 days behind you on 1/2 a tab at night. So far so good

Same observations for me. The sedation was too much and although all those pros the sedation made me stop after trialing for three weeks.

Are you only taking Guanfacine or do you pair it with something else

What are your symptoms associated with hyperandregeneric pots and how were you diagnosed?

I don’t understand how .25 would sedate you. My 5 year old was taking 1-2mg to help her sleep and she was wide awake 😭

What is your cerebral blood flow looking like during all of this? I can’t speak to your case specifically but for me I have pretty severe cerebral hypoperfusion that is driving the dysautonomia symptoms hr and bp.

I’m only taking it at bed time. I’m a little sleepy for awhile in the morning but my brain fog has noticeably decreased. Executive function has also improved. Someone said they take it at like 7pm so they aren’t so tired in the morning.

I have some excessive sweating as a side effect 😭 do you feel it could help with that bc of the sympathetic effect? Beta blockers helped a little for me

Can I ask what your blood pressure looks like and if it was affected? My blood pressure sits on the lower to mid side but my pots symtoms a sympathetic so I’m scared to try

My daughter has been on Guanfacine for 5 years and the extended release did not work for her, like she never even took it

Also my doc said give it a month before deciding the side effects aren’t worth the benefits.

Guanfacine leveled out for me! Also I found 1mg extended release has a much smoother effect for me. You can’t split the pills but I found 1mg ER at night helped w insomnia and carried over into the AM well.

when I started propranolol I was exhausted for weeks, but I think it was my body adjusting from being in fight-or-flight for soooo long. maybe this is what’s happening to you too? i’ve been on a low dose of ER Guanfacine now for over a year now and it has helped my nervous system so much 🥰
