Too much mestinon ?

I accidentally took 2 dosages of mestinon today. I am wondering if anyone has done this and if this is very dangerous? I am a bit nervous as to what might happen. Usually I take 60 mgs but I took 120 by mistake.

If you feel any ill effects (for example, if you feel like your MG is getting worse), get to the doctor right away.

But honestly, you're probably fine. I usually take 60 to 90mg, but my neuro has said I can go up to 120mg without worry (I'm about 5'7" and 125 pounds if that gives you a sense of dosage to size).

You'll be okay. I took 120 quite a few times, and had no problems.

Thank you both for your replies, thankfully nothing happened lol I just tend to freakout about everything since being diagnosed.

I will also add, that when the MG starts to be under "somewhat" control that you might not need as much mestinon and seem like your symptoms are getting worse when really the MG is getting better. You can see how you feel after appox. one hour after you take the dose, which is the peak. Mestinon usually lasts 4-5 hours. So I try to use these guidelines when I need to adjust. My neuro doesn't want me to take more than 60 mg - 5 times a day. I recently had to adjust from 60 mg to 30 then to 15. IVIG is working for me. Good luck.
