What are the side effects of Mestinon (pyridostigmine) for myasthenia gravis?

Mestinon side effects generally fall into two categories. Many are linked to taking too much of the medication, so it's worth keeping your neurologist in the loop if anything feels off.

Muscarinic side effects (often related to the digestive and glandular system):

- Nausea and vomiting
- Diarrhea and stomach cramps
- Increased saliva and mucus
- Sweating
- Small pupils

Nicotinic side effects (related to muscles):

- Muscle cramps and twitching
- Weakness
- A skin rash can also occur in some people Serious side effects to watch for:

- A cholinergic crisis — this is a dangerous worsening of muscle weakness caused by too much of the medication, and it can affect breathing. This is a medical emergency.
- Severe breathing problems

Seek medical help immediately if any serious reactions occur.

One MGteam member shared that taking a probiotic alongside Mestinon almost completely stopped their diarrhea — worth asking your doctor about if stomach issues are a problem!
