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...

Take of yourself,
Good luck with your testing,

I'm glad to hear that your life has improved since taking the mestinon. That gives me hope.
Thanks again and you take care too!

Mestinon does not work for everyone, but most of us get help with it. I had to take as much as eight 60 mg mestinon pills during the day to function when MG was first diagnosed and that didn't resolve my double vision. Only after I took prednisone for about 4 months at 60 mg/day did the double vision go away.
My mestinon prescription was up to 120/mg per every 4 hours as needed. The as needed meant that I could tell if I had enough or not. I couldn't take 120 per time, so took 60 mg every 2 hours if I needed to be very active, the rest of the time much less.
Mestinon helps, but does not stop the deterioration of our nerve to muscle connections and so that is why folks with MG have to take something to slow down our immune system from manufacturing antibodies that attack us. Mestinon is sort of like taking an aspirin for a brain tumor-- relives the symptoms but for most of us does nothing to prevent MG from getting worse.
Mestinon goes into our body, in about 30 minutes begins to help, and about 4 hours later is gone. It really is best described as acting like an aspirin on a headache. So if you wake up feeling better it would be unlikely it was from mestinon unless you took it at least a half hour before you felt good, as any you took more than 4 hours ago would have worn off.
The CT scan is likely to see if you have an abnormal thymus gland, as that sometimes is the cause of MG. In normal adults, it is almost shrunken to nothing having done its job when we are children. Sometimes MG can be a side effect of cancer, especially thymus cancer, but others too, and so a good workup includes checking for cancer of any kind. This is rare, but does happen often enough to be tested.
There are several types of MG, with different tests for them as well as some kinds that seem to not show up on existing tests. So diagnosis then is often based on symptoms and sometimes response to mestinon.
Often MG is associated with other auto-immune diseases. It seems that when our immune system runs amuck, it can attack many different systems. I have 3 different auto-immune conditions including MG. So treatment with an immune system suppressant helps in all of those.
And of course there is always the possibility that it is not MG. A mis-diagnosis is worse than no diagnosis.
Good Luck

Thank you for your reply, it’s so helpful in understanding this disease. I struggle as it is with FMS/CFS now this. It’s very upsetting and I wonder how I’m going to cope with another illness.
I can’t imagine taking the mestinon at such a high dose. I’m having issues just taking it at 30mg. It makes me feel sick. I’m to up my dose to 60 mg 3x a day.
Thanks again and good luck to you too.

After a month or two the side effects became less (or maybe I got used to them). I wanted to function, and the high doses let me. I quit taking it about 5 pm and not overnight as it gave me leg/calf cramps that were vicious. I found stretching by doing pushups against the wall helped with the muscle cramps. I also got eye twitches.
However, for 4 months without the doses of mestinon I would have been unable to do much at all. My wife was in cancer treatment at the same time and I wanted to be functional.
I chose prednisone as the immune system treatment as it was the fastest and it did not tie me to a hospital like IVIG. I think a month or two at 60 mg/day would have worked -- but my neuro wanted me to start at 20, then move to 30 and stay there and just wait. I was in a hurry and so she OKayed the higher dose that worked good to get me reaonably normal by 4 months from diagnosis. Of course there were mahy side effects of prednisone too, but after I got the symptoms under control, it takes much much less prednisone to continue with control.
I did not want to delay getting my life back, and larger doses of mestinon and prednisone were a way to do that and I figured the side effects were worth ridding me of the MG problems. And for me, that was true.
Good Luck

I will try Imodium, thanks for the tips!! I definitely make sure now I have a full stomach when I take the mestinon. I made the mistake several times of not eating something first and I got so sick. Now I eat a little more than usual and I notice the fuller I am the better, less side effects.
Also, this last week I noticed my calf’s were really hurting and I wasn’t sure why. I have fibromyalgia and I suffer from chronic muscle pain, but this is different. Like a cramp exactly what you described. Now I know I wasn’t crazy and it’s the mestinon. I also been having the muscle pain in my traps and neck.
I really hope I don’t have to go on any steroids. I use to get trigger point injection every month and I gain 40 lbs. I’ve worked hard to keep my weight down. I don’t like the side effects either.
I’m so sorry to hear your wife was battling cancer and you fighting your own battle with MG. That had to have been so hard. Thank goodness you were able to get the right combination of medication that made it possible for you to function. I’ve been amazed by the stories in this group. The information that is able to be exchanged between one another is so valuable. We can fight the fight together. Thanks again and I can’t tell you how much I appreciate you taking the time to respond to my posts.
Robin
I have my second appointment with the neurologist in 3 weeks. All of this is somewhat overwhelming since I am newly diagnosed. I will definitely keep an open mind and have patience.
Wskimball , I do know what you mean about the severe cramping, I have had the same problem. Yes it makes you cry. I have had several episodes this past week.
Good luck to everyone and thanks for the replies and input! This group is amazing and at least I don’t feel so alone anymore.
Take care everybody,
Carl
As for the sever hand and foot cramping, I am going to start tomorrow doubling my Mestinon to see if that helps. I am dreading the return of loose stool, and diarrhea, and all the issues that come with it but the cramping is bad. By the way, taking a probiotic, a good probiotic seems to help. Hang in there everyone, we have to keep up the good fight.
Walter
I was also diagnosed two years ago also but all my blood work did come back negative. I finally had the musk test done then it was confirmed . The only medicine that helped immeatatly was prednisone . Now it is a combination of mestinon prednisone and imuran.
Good luck
Mark
Thanks again.
