Common Questions and Answers about How epinephrine works
epipen
I have to go have a tooth filled tomorrow and I'm somewhat apprehensive about the anesthetic. I know most often the ones they use contain epinephrine because it's a vasoconstricter and causes the anesthesia to work longer. I know you can request the anesthetic without the epi but then it wears off quickly (like when they are drilling on your tooth). I asked my cardiologist and he said if I didn't get a big dose of the epi, if it was mixed, with the beta blockers I should be ok.
It probably isn't the lidocaine, it's the epinephrine that is in the lidocaine. You can ask your dentist to use an anesthetic without epinephrine, I have had tons of dental work and always ask for that. Dentist doesn't mind at all and I've never had any problems. It doesn't last as long but if you start to feel anything while they are working the dentist will just give you more. I have done fine with it.
Hi,
It is a serotonin and nor epinephrine reuptake inhibitor. The name of the neurotransmitter is nor epinephrine it is different from epinephrine.
Most of the side effects occur during the period when one is taking the medication. But the important thing to remember is to follow the doctors instructions carefully. To reduce the incidence of side effects it is always started with a low dose and then it is gradually increased.
Strattera... my salvation for concentration. Been taking it 7 years now to counteract the "attention and concentration deficits related to chronic dizziness," as the neuro put it. Gets rid of the constant struggle to fix my eyes and brain on the world. Such a relief it was. It's an excellent medication for me even though I don't have ADD.
Thanks for that explanation, Bob.
I have no idea if MS has any effect on epinephrine and norepinephrine, but I can't imagine how.
I had to get stitches last night, and was given 5-6 shots of epinephrine and lidocane. I told the intake nurse I was taking synthroid (which I presume implies thyroid problems). I felt a little "unusual" afterward (pounding heart, feeling calm and detached..), and was googling the side effects of the shot.. an article said this:
"Additionally, epinephrine and lidocaine usually aren’t used in patients with thyroid disease, or disease of the kidneys or liver.
m wondering with my heart problem how dangerous is it to get a dose of epinephrine and how will that affect my heart? I had an epinephrine dose in the early nineties due to a breathing problem, but that was before I was diagnosed with the mvp and atrial misfire.
I had a 2nd trimester miscarriage the day that I had a mole removed at my dermatologist. They used Epinephrine and Xylocaine and when we received the autopsy report it revealed that my baby was perfectly normal and healthy without chromosonal issues prior to him dieing in my womb that day. Has anyone experienced this or known anyone who has? I researched on the web and found many warnings about pregnant women receiving Lidocaine from the dentist but not what they gave me.
It makes a lot of sense to question whether to wait until he's done the test before taking a medication that blocks the action of epinephrine (metanephrine is the inactive metabolite of epinephrine, I believe what's left after the epinephrine is spent, and normetanephrine, the inactive metabolite of norepinephrine, which they also measure).
So far I always got eye drops without epinephrine/or something equal to epinephrine, but this last eye doctor did not want to use any drops at all. He examined my eyes without dialating them.
And it is a stimulant as well. It works on the Dopamine system, unlike other anti-depressants, which primarily work on the Nor-epinephrine and/or Serotonin systems. That's why the word, 'atypical'. Dopamine is an excitatory neurotransmitter (a stimulant).
Bupropion does help with mild to moderate levels of anxiety, but it is not known to more beneficial than the typical anti-depressants when the anxiety is severe.
It's the epinephrine in the anesthetic that causes the racing heart, etc. Next time you're at the dentist and you need/want an anesthetic ask for one WITHOUT epinephrine. The medication generally takes a little longer to "kick in" and wears off faster, but your dentist will work with you for maximum comfort.
Will the loose skin return to normal, how long does it take, and how can this be prevented in future dental work? Did the dentist inject the local too quickly or not quite in the right place? Did the local get into the soft tissues of my face and I don't know, displace adipose tissue or something, is that even possible?
husband has had low cortisol but works nights so dr does not think it is low because days and nights reversed although has ordered cortisol 1 hour after he wakes. AM ccrtisol has been between 1 and 5, below range low of 6.7. although cortisol stimulated to 13.7. Dr ordered 24 hour urine for catecholamines in July and December. both times epinephrine NE <5 &<6 below clinical reportable range.
In the second trimester it's safe.. I had a molar removed. You just have to get signed off by your ob.
Hi, welcome to the forum, Epipen delivers a measured dose of epinephrine (also known as adrenaline) using autoinjector technology, most frequently for the treatment of acute allergic reactions to avoid or treat the onset of anaphylactic shock. In certain cases it can be used to stop local bleeding.
Epinephrine is known to act on the uterus through beta 2 receptors and can cause relaxation of the uterus. At term, it can prevent the contraction and delay the labor.
