Pyridostigmine

Stabilize Your Heart Rate

Pyridostigmine helps to alleviate a rapid heart rate that occurs when standing, promoting stability for those experiencing autonomic dysfunction.

Improve Exercise Tolerance

By regulating the autonomic nervous system, pyridostigmine may enhance exercise capacity and neurovascular dysregulation, helping you regain physical activity.

Improves Orthostatic Hypotension (OH)

By enhancing nerve transmission, pyridostigmine improved standing blood pressure in patients with OH, without raising blood pressure while laying down.

Study #1: Pyridostigmine Improved Peak VO2 and Exercise Capacity in ME/CFS Patients

In this randomized, placebo-controlled trial at Harvard involving 45 patients with ME/CFS, pyridostigmine was found to improve peak oxygen uptake (VO2), indicating enhanced exercise capacity.

Study #2: Pyridostigmine significantly improved blood pressure related issues in 43% of POTS patients

This single-center study from Toledo Medical Center found that 43% of 203 total POTS patients experienced significant improvements in orthostatic intolerance. The symptoms that improved the most included fatigue (55%), palpitations (60%), presyncope (60%), and syncope (48%). [Syncope = fainting]

Study #3: Pyridostigmine improved fatigue, exercise intolerance, and cognitive function in 55% of ME/CFS patients.

In this observational study at Brigham and Women’s Hospital, 55% of patients with ME/CFS treated with pyridostigmine for over 6 months reported improvements in exercise tolerance, fatigue, and cognitive function.

Exercise Capacity in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Treated with Long-term Pyridostigmine

Study #4: Pyridostigmine improved central cardiac hemodynamics and exercise capacity.

In this retrospective study, long term treatment with pyridostigmine showed improved aerobic capacity in ME/CFS as measured by improvements in central cardiac hemodynamics.

“I’ve tried many drugs for my POTS/Dysautonomia with no success, but Mestinon is really helping me. I’m able to function more, and my fatigue is reduced. It sometimes has a side effect of extreme perspiration, but I can manage. It has been a game changer for me.”

“Pyridostigmine is way better for me. Propranolol helped somewhat with POTS but made the fatigue worse, and didn’t do much for the fight or flight. Pyridostigmine doesn’t cross the blood brain barrier though, it helps with POTS and shifting the body to a parasympathetic state but it’s unlikely to hel…”

“It’s been a life saver for me. I’ve been on it almost two years now…I find mestinon really helpful for blood pooling, fatigue and brain fog. It was a game changer in allowing me to be upright again.”

“Roughly 70% of patients reported that pyridostigmine was at least somewhat effective for POTS.”
