Thx Rhanson ... for mentioning my earlier reply concerning the heating pad. And I was able to improve the strategy even more with a full mattress heating pad ... which meant that wherever/however I may have moved around on the bed overnight ... the mattress pad kept the cramps away. The problem with just using the small heating pad is you have to keep repositioning it all night on the particular cramping locations on your legs. The overall mattress pad keeps the entire mattress warm and I was very happily relieved and surprised to start enjoy full nights of sleep. E.g. Prior to heating pads, the only solid solution I found was staying up half the night, pacing around the house!! (Now I hasten to add, all the usual prudent points of advice like ensuring the heating/mattress pads have great safety shut offs, etc. etc.). Best wishes to concernedb ... it is a indeed a most irritating side effect of the mestinon and hopefully something we can leave behind over time as our docs decrease the mestinon/auto immune drugs balance.

I eat 1-2 bananas daily and it helps. I cramp up bad if I'm out and don't have one.

I eat a banana a day. It's worth checking his potassium level. My understanding is that Mestinon depletes potassium from the body. Leg cramps are one sign of low potassium. Don't just treat the symptom. Make sure there is not an organic cause. I have noticed the cramps get much worse minutes after I take my Mestinon extended relief pill at bedtime. I only take it after I am in bed and not moving around. That prevents a lot of cramping.

I have found that coconut water not only taste great, but keeps your potassium levels adequate and keeps you hydrated.

I took apple cider vinegar tablets from the health food store. It really does work. You can also drink an apple cider vinegar cocktail (I/2 cup water, 1-2 tablespoons of apple cider vinegar and 1 tablespoon of honey) that helps too, but I got tired of the taste. :-b

Is it possible to take Potassium tablets or something like that to get the levels back up in order to avoid cramps.

Leg and hand cramps are a big issue in my case.

Thanks

How much depends on lab test. Too much can give other issues. Take care

This isn't horrible, because I like canned spinach, but is has just about the biggest dose of potassium you can get in a food. It always helps my me Bananas aren't nearly enough for my cramps.

eat potatoes, bananas etc.

That isn't a long of mestinon, but you could also try to reduce the mestinon intake somehow.

Hi everyone,

I'm new to Daily Strength and this post has been helpful, thank you! My fiance was recently diagnosed with MG and I'm just trying to read as much as I can about it and try to find ways to reduce his discomfort.

He's also on Mestinon as well.

potassium, i take 3x450mg every other day, works pretty good, i still get hand and finger cramps, but my leg cramps have subsided, also occasional toe cramps. But potassium seems to fit well,

Mestinon does not directly reduce potassium levels. However, it can cause excess sweating, salivation, or diarrhea with can indirectly effect potassium levels.
