Myasthenia Gravis Support Group

Myasthenia gravis (MG) is a neuromuscular disease leading to fluctuating muscle weakness and fatiguability. The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest. Although myasthenia gravis may affect any voluntary muscle, muscles that control eye and eyelid movement, facial expression, and...

On friday had dental surgery done with several shots of lidocaine in upper gum and roof of mouth. Did fine during procedure,as was walking to car legs became rubbery and arms heavy. Made it home on side streets in case needed to pull over. Once home slowly experienced generalized weakness and fatigued..spent day in recliner and slept 12 hrs. that night.

Saturday did grocery shopping and 3 loads of laundry in am-slowly,then rested as was still weak and fatigued. a nap and 11 hrs of sleep this day/might.

Sunday for some reason was a little weaker and extremely fatigued (even talking was an effort), just took it easy all day. Monday got some strength back did a couple house chores- cooked some food for week,and rested as much as possible in between. Today doing some better- legs are def. weak, do not feel fatigued...still laying low as I go back to work tomorrow- glad I took off an extra day to recupe.

I am also taking amoxcillin 500 mg every 8 hrs. this might be affecting me?. I had to be down to10mg of prednisone for surgery and on monday i upped it to 12.5mg to help relieve symptoms. My Mg was fairly stable prior to surgery....so for anyone needing any medical work with lidocaine take caution and have plans in case have a reaction.

P.S. i have had lidocaine and versid in past for procedures with no problems but will be very careful in future. and give my neuro a heads up beforehand.

Thanks for the report, that's good to know. Hope you're back to full speed soon!

Thanks for the warning
I went inot crisis 5 days after lidocain and some say it only may have caused the problem. I now need more work done am not willing to take lidocain. So I am going to U of M to talk about alternative ways to deaden my nerves so I can have lidocain.
Oh well

Well, that settles it. Nitrous oxide for me going forward.

My dentist (who doesn't have NO2 capabilities) actually pooh-poohed me when I expressed some concern about this. I think (I know) he didn't want to lose me and my insurance. I haven't had any procedures since my dx, but this sounds like a rotten reaction. I always imagined the effects of lidocaine would be immediate, but with MG, you can exert and exert and then feel it hours or days later.

I'm bumping this up to go with the Dentist post. There are other "caines" less likely to cause problems like the faster acting ones, (remember novocaine is right out). I think I will add these discussions to the Links group. "Use with caution" means just that and if you chose to have dental work with lidocaine, be sure to have someone there to drive you home or to advocate at the ER.

I have used lidocaine different times and don't remember any problems, but it may have been before my diagnosis.
I do; however, experience mg symptoms with amoxicillin. You might want to consider, too, that the antibiotic may be adding to your weakness as well.

Thanks Olliepop, your probably right...I am doing better now but not back where i was prior to surgery...last dose of antibiotic is tonight. Guess I will put up weakness since i can function enough and breathe ok...better than getting an infection.

Interesting you had mg symptoms with amoxicillin, this one was not on my list of meds to stay away from but guess will have to be cautious with all antibiotics from now on. Definitely schedule a light week when on them.

This is interesting mermaid3. I had a tiny procedure to day - two very small biopsies where taken from my skin. So I had local anaesthesia in two different places. I had to to errands afterwards and after 1 and 1/2 hour I was so week and sleepy I had to go home. I fell asleep 15minutes after I came home and woke up 3 hours later because my phone rang. Now 1/2 hour later I'm still very week - more than I have been for the two months I have been taking Mestinon (newly diagnosed). So I sat to my computer and started to google lidocaine and MG and this led me to this thread. I'm not on any antibiotiks.

Yesterday 5-24-2017 I had an appointment with a new doctor, a Urologist. My GP sent me to the Urologist because my PSA Count has been increasing. Because I read this post recently I knew about the Lidocaine. My Urologist said I needed a biopsy of my prostate and that it would be done in his office with an ultrasound technician and the use of LIDOCAINE. I told him that I had MG diagnosed in December 2016. I had written on his forms that I had MG. But he had not read the forms that I submitted.

He then said that the biopsy will be done in the hospital. He said that he has another MG patient who also had MG but did not inform him that he had MG. This patient has a prostate with cancer and required surgery. The surgery was done in the hospital. The patients stopped breathing. The hospital had the equipment to save his life. In an office setting using Lidocaine he did not have equipment to intubate, etc. My Urologist said, "It scared me to death."

So in summary: Thanks for the post regarding Lidocaine.

Ladies, for the men in your life, fathers, brothers, husband and/or boy friends, make sure they get PSA blood tests.

If you have MG don't use Lidocaine.

They will not be using it on me in the hospital when I have my biopsy done in about a week.
